A 20‐year‐old male sustained a severe crush injury to his left leg, resulting in amputation of the foot at the level of the distal tibia. Tsu-Min Tsai Christine M. Kleinert Institute for Hand and Microsurgery, 225 Abraham Flexner Way, Suite 810, Louisville, KY 40202, USA E-mail : bhuvaneswari.bibleraaj@uhsm.nhs.uk Advancements in microsurgery have made lower extremity reconstruction possible even after major soft tissue loss or tibial nerve disruption. Zuker2 also talked about two significant problems associated with the use of loupes: slippage of the glasses towards the tip of the nose, and postauricular pain. L’artère était disséquée (radiale ou ulnaire) et le clamp démontable était introduit par un trocart sous la peau, puis installé sur l’artère qui était sectionnée. However, there exists no consensus on its use in microsurgery as concerns time of introduction (pre-, intra- or post-operative), recommended dosage, or duration of utilization. The rationale for hand transplantation. We dissected the donor limb and the recipient's arm simultaneously to identify anatomical structures. Nos résultats démontrent la faisabilité de microanastomoses vasculaires par voie endoscopique. A.J. Hirudin is a new antithrombotic agent and is reported to be much more powerful than heparin on a gravimetric basis. Le taux d’échec des lambeaux libres est d’environ 5 %, le plus souvent en lien avec une thrombose du pédicule vasculaire. All anastomoses were patent. A routine microanastomosis was done with one of seven irrigation solutions employed in the study. She earned her medical degree from Northeast Ohio Medical University in Rootstown, Ohio.

Various innovations have been described by surgeons in order to resolve the pressure in these areas. Biography. 3.5) for most procedures. AAOS Symposium on Microsurgery Practical Use in Orthopaedics (1979) C. V. Mosby St. Louis 36. Dr. Ben Tsai, MD is a colorectal surgeon in Indianapolis, Indiana. Surgical robots can extend the capabilities of surgeons by reducing fine tremors, increasing manual dexterity and offering real-time 3D visualisation during endoscopic surgery (1, 2). microsurgery became more prevalent and experi-ence with free tissue transfer mounted, the success rates of microvascular procedures also climbed, to >90% today (Table 1). These agents have been used clinically for several years. All DeepDyve websites use cookies to improve your online experience. These changes result in either fewer cone photoreceptors in the central macula, or a change in the orientation of their axons. 240-248, A comparison of irrigation solutions for microanastomoses, A new microsurgical research model using Thiel-embalmed arteries and comparison of two suture techniques, Treatment of pectoralis major flap myospasms with botulinum toxin type A in head and neck reconstruction, Foveal phase retardation changes associated with normal aging, Vascular microanastomosis through an endoscopic approach: Feasibility study on two cadaver forearms, The learning rate in three dimensional high definition video assisted microvascular anastomosis in a rat model, The effect of surgical and chemical denervation on ischaemia/reperfusion injury of skeletal muscle. The anastomoses were performed faster using HM than SI sutures (7:58 min vs. 12:41 min, respectively). Il n’existe pourtant pas de consensus sur son utilisation en microchirurgie, que ce soit sur le moment de son introduction (pré-, per- ou postopératoire), la durée ou encore la dose d’utilisation. The size of the incisions for free muscle flaps is often very large, and a source of deep adhesions and unaesthetic scars. There was a significant difference compared to the control groups having received heparin, urokinase, phentolamine, or mixtures of urokinase + heparin + phentolamine or tPA + heparin + phentolamine.However, no significant difference appeared between these different groups [10].Cox et al. This group of patients was followed up at regular intervals with clinical examinations, digital photography, range of motion (ROM) of the neck in different vectors, and neck disability system (NDS) questionnaires. L’anastomose durait deux heures sous insufflation, sans fuite. Annular regions of interest ranging from 0.25° to 3° eccentricity and centered on the fovea were used to generate intensity profiles from the phase retardation data, which were then analyzed using sine curve fitting and Fast Fourier Transform (FFT). No consensus exists on the ideal anticoagulation protocol for microsurgery. He is affiliated with Franciscan Health Mooresville, Community Hospital South, and Franciscan Health Indianapolis. 2002;74(6):749-753.

Tsai-Lung Tsai DO . Des résultats préliminaires dans 4 études semblent toutefois inciter à recourir à cette pratique. Grahaam3 mentioned a third concern: discomfort of the nose. . © 1997 Elsevier Science Ltd. Rinsing rat femoral arteries with various fluids in experimental conditions similar to those in clinical practice was found to have deleterious effects on the intimal and medial layers of the vessels. They have different mechanisms of action compared to heparin, a longer half-life and much higher bioavailability. The results indicate that high concentrations of topically administered heparin or hirudin minimize the systemic complications and maximize the antithrombotic effects. Presented at the Sixteenth Annual Meeting of the American Association of Hand Surgery, Los Angeles, California, October 24, 1986. e23-e28, Vision Research, Volume 51, Issues 21–22, 2011, pp. Eleven of them reported muscle twitching as a post-operative complication and are therefore included in this study. The antebrachial skin was detached then distended by gas insufflation. As far as animal research is concerned, 9 studies out of 11 showed the superiority of topical intra-operative heparin compared to saline in improving free-flap survival rates through improved patency of the anastomosis. Although the clotting mechanism prevents injured tissues from bleeding, it can be disruptive to a microvascular repair - inhibiting blood flow and promoting flap failure. Lignocaine 2% was found to be extremely damaging to the whole vessel wall, and highly thrombogenic. Board Certified: ... Hand Surgery encompasses neurosurgery, plastic, orthopedic, vascular, and microsurgery techniques covering just about every problem from A to Z. His clinical research studies the anatomy of microsurgical approaches and clinical outcomes of microsurgery for aneurysms, AVMs, and bypass surgery. In this study, low molecular weight heparin (Certoparin, Sandoz) was topically administered in a rabbit ear arterial crush-avulsion thrombosis model and compared with heparin. The patency rate in the heparin group was 95% (19 of 20) at 24 hrs and 80% (16 of 20) at 7 days. Some previous studies have shown that local vascular endothelial concentrations of heparin are 30 to 7500 times greater than those found in the circulating blood. Then she went back to Massachusetts for a year for boarding school. https://doi.org/10.1016/0363-5023(88)90195-5. It is our experience, and indeed was also reported previously, that high … DeepDyve's default query mode: search by keyword or DOI. Pour la diminuer, le but de ce travail était d’étudier la faisabilité de microanastomoses vasculaires par voie endoscopique. Chez l’animal, 9 articles sur 11 ont montré une amélioration du taux de survie des lambeaux grâce au flush des vaisseaux par du sérum hépariné avant la fin de la réalisation de l’anastomose micro-chirurgicale. Margaret Tsai, MD, is an Associate Staff Member in the Department for Rheumatic and Immunologic Disease. In the saline control group, the vessel patency rate was 17% at 24 hrs and 13% at 7 days. All in all, fifteen articles in animal and human research were selected. Three minor leaks occurred with HM sutures versus one with SI sutures. The phase retardation changes in the central macula indicate structural alterations in the cone photoreceptor axons near the fovea as a function of age. Les difficultés principales ont été causées par un fil trop long et une aiguille trop fragile. I have a very difficult case and I have full confidence he can make them perfect ! In the saline control group, the patency rate was 19.23% at 24 hrs and 15.38% at 7 days. Studies should be conducted to decide whether or not to validate a rather ritualistic practice that consists in irrigating the relevant vessels before anastomosis; does it or does it not improve the patency rate? Dr. Tsai attended the University of New England, where he received his medical degree, and completed his internship at Rowan University. All microsurgeons reported improved comfort for the 3D HD video system but found the image quality of the conventional microscope superior, facilitating technical ease. Tsai Ing-wen (born 31 August 1956) is a Taiwanese politician and academic serving as the seventh president of the Republic of China (Taiwan), since 2016.A member of the Democratic Progressive Party, Tsai is the first female president of Taiwan.She has served as Chair of the Democratic Progressive Party (DPP) since 2020, and previously from 2008 to 2012 and 2014 to 2018. This article reviews major pharmacologic modalities of anticoagulation, delineates the mechanism of action and study of efficacy of each agent, and compares the risks and benefits of popular anticoagulation therapies. Do not surround your terms in double-quotes ("") in this field. Start a 14-Day Trial for You and Your Team. This large sample size demonstrates systematic changes to the central cone photoreceptor morphology using scanning laser polarimetry. We have successfully evaluated all outcomes. Dr. Ben Tsai, MD is a colorectal surgeon in Indianapolis, Indiana. However, image quality was rated inferior with the 3D HD system resulting in prolonged anastomosis times. Save any article or search result from DeepDyve, PubMed, and Google Scholar... all in one place. A scanning laser polarimeter was used to acquire 15° × 15° macular images in 120 clinically normal subjects, ranging in age from the third decade to the eighth. Designer adjustable bracelets, stud & drop earrings, necklace, cufflinks. No statistically significant difference was found between the effects of Ringer's lactate and normal saline. When both are administered systemically, one of the common complications seen is bleeding. The donor's arm was irrigated with UW organ preservation solution at 4 degrees C, amputated 5 cm above the elbow, and transported in a cool container. The right biceps femoris muscle was used as the experimental muscle flap model. He also completed his residency in general surgery at St. Joseph’s Regional Medical Center La taille des incisions des lambeaux musculaires libres est souvent très grande, source d’adhérences profondes et de cicatrices inesthétiques. . This is the first study to evaluate the feasibility of a Thiel-embalmed artery model for research purposes. The HM microvascular suture is a promising technique that requires further in vivo validation. A higher patency rate at 7 days was obtained in groups treated with high concentration of heparin and hirudin. Khouri’s25 survey of 9 microsurgeons “clearly indicates that operative experience is the single most critical factor related to improved success rates. Antithrombotic drugs, such as heparin, have been used in the clinics for a long time. in Louisville, KY-Jun 15 2016Review for Dr. Tsai. Progressive changes in robotic and computer-guided systems have significantly altered operating practice across different medical and surgical specialties. To assess the utility of the Thiel arterial model in microsurgical research, we compared interrupted horizontal mattress (HM) sutures to simple interrupted (SI) sutures in human vessels. The aim of this study was to determine whether or not the use of intra-operative heparin, in its systemic or topical forms, can bring about improved survival of free flaps, and if and when it should be recommended in microsurgery. Thrombogenic occlusion, at the anastomotic microvessels, contributed impaired blood flow to flap failure. The effect of an orally active low molecular weight heparin (LMWH) derivative conjugated with deoxycholic acid (DOCA) on the patency of anastomosis of the crushed rat artery was investigated, expecting its antithrombogenic effect. The animals were divided into three groups: LMWH, heparin and saline control groups. There are few recent innovations in anticoagulation therapies for microsurgery, however, and anastomotic thrombosis remains an occasional cause of surgical failure. 15,000 peer-reviewed journals. The authors report their experience using botulinum toxin (BTX-A) injections as a treatment of PM flap myospasm complications in head and neck reconstruction. Finally, in clinical studies concerning humans, as of now no prospective randomized trial has proven that use of topical intra-operative heparin to ensure vessel irrigation in ex-vivo flaps is likely to increase free-flap survival. He is a Fellow in the American Academy of Orthopaedic Surgeons, holds memberships in the American Society for Reconstructive Microsurgery and the International Society of Reconstructive Microsurgery, and is an active member of the American Society for Surgery of the Hand. La peau antébrachiale a été décollée, puis distendue par insufflation de gaz. Edges were evenly everted without any intimal flaps with HM compared to SI. Comparable learning rates for anastomosis time were demonstrated for novice microsurgeons and modified OSATS scores did not differ between the different viewing technologies. We report a case in which vasospasm was quickly relieved by topical application of fasudil hydrochloride. Atroshi I, Gummesson C, Johnsson R, McCabe SJ, Ornstein E. Severe carpal tunnel syndrome potentially needing surgical treatment in a general population. In the hopes of shortening the size of incisions, the goal of this work was to study the feasibility of vascular microanastomoses through an endoscopic approach. It’s your single place to instantly 60 Femoral arteries of 30 rats, divided into three groups of 20 each, were reanastomosed. Degenerative histology and apoptosis scores were significantly better in groups to which BoNT-A and SD were applied 1 or 7 days before the ischaemia/reperfusion cycle. There seems to be a benefit with the addition of either vasoactive agents or clot-active agents to the microvascular irrigating solution during construction of a compromised microanastomosis. Anticoagulation in microsurgery . Despite 12‐h warm ischemia, replantation was attempted after radical debridement, bone shortening, and proximal fasciotomies. Lactated Ringer's solution is commonly used as an IV treatment for dehydration or acid-base imbalances. In clinical research in humans, there has been no prospective randomized trial studying the action of topical intra-operative heparin in vessel irrigation of ex-vivo free flaps before vascular repermeabilisation. En revanche, en ce qui concerne l’utilisation d’héparine systémique, les résultats sont partagés avec 2 études pour et 2 études contre. The medication of oral LMWH-DOCA conjugate has been vetted in microvascular anastomosis of the crushed artery. 1528-1536, Journal of Plastic, Reconstructive & Aesthetic Surgery, Volume 65, Issue 2, 2012, pp. De nombreux agents pharmacologiques ont été étudiés afin d’optimiser le succès des anastomoses microchirurgicales et ainsi d’améliorer la survie des lambeaux. The advent of microsurgical tissue transfer including replantation greatly has expanded the scope of reconstructive surgery. The assembling and disassembling of the clamp were time consuming. Evidence has accumulated to indicate a beneficial effect of heparin on anastomotic patency, implying that its topical use is critical to success even in routine microvascular repairs. Nevertheless, all the arteries in each group remained patent 4 days after rinsing. Application of soft foam or different types of padding, and even dental putty, has been applied to the undersurface of the nose or ear pieces with some degree of relief.3 In order to avoid slippage, sticky tape has been used between the brow bar of the glasses and the forehead, Figure 1. A comparative study of irrigating solutions that contained various clot-active substances and/or vasodilating substances was done using a crush injury model of the rat's femoral artery. Quinze articles ont été retenus en recherche animale ou chez l’homme. Lo S(1), Sebastin S, Tsai L, Pin PY. Doesn't seem to want to take time & interest in patient. Copyright © 2021 Elsevier B.V. or its licensors or contributors. discover and read the research Vessel patency, leak and stricture were evaluated using angiography, and vessel wall architecture was evaluated using light microscopy and scanning electron microscopy (SEM). ACT, PT and APTT performed on samples drawn one hour after drug administration were within the normal range in both the control and the treatment groups. Lees VC, McCabe SJ. The anastomosis lasted 2 hours under insufflation without any leak. It is intricate and challenging, and there is always something different every day! THE MICROSURGERY FELLOWSHIP AT CHANG GUNG MEMORIAL HOSPITAL, TAIWAN This sentinel program is the Microsurgery Fellowship at Chang Gung Memorial Hospital (CGMH) in Taiwan that was established almost 3 decades ago. Chez l’homme, il n’existe pas d’essai prospectif contrôlé randomisé étudiant l’action topique peropératoire du sérum hépariné pour le rinçage des vaisseaux des lambeaux libre ex-vivo en ischémie froide avant reperméabilisation vasculaire. The anastomosis was performed in good conditions. It's not the same as saline, although the two serve similar purposes. Author information: (1)Department of Hand and Reconstructive Microsurgery, National University Hospital, Lower Kent Ridge Road, Singapore, Singapore, stevenjlo@gmail.com There are very few reports in the literature … A systematic review on the PUBMED database enabled us to identify articles evaluating the benefits of intra-operative heparin with regard to free-flap survival. Four incisions, 1 cm each, allowed the insertion of four trocarts connected to the telemanipulator. The purpose of this study was to evaluate the potential to replace the binocular microscope for microarterial anastomoses and assess the rate of learning based on surgeons' experience. In the first stage, the effect of surgical denervation was investigated in four groups each containing six rats. Specialties: Hand Surgery, Orthopedic Surgery. Success in microsurgery requires intact circulation via microvascular blood vessel anastomoses. Personal innovation of loupes stabilization system. Only two of the 11 patients required two additional BTX-A sessions. Reste à réaliser le premier cas clinique, par exemple sur un lambeau de grand dorsal (latissimus dorsi). Anticoagulant drugs such as heparin have been used topically in our previous studies to avoid bleeding complications observed with systemic administration. Top special gift idea: … Une revue de la littérature effectuée sur la base de recherche PUBMED a permis d’identifier les articles étudiant les bénéfices de l’héparine peropératoire sur la survie des lambeaux libres. Scanning electron microscopy revealed the different extent of the clots on the injured intimal surfaces of the vessels in different groups. Get unlimited, online access to over 18 million full-text articles from more than 15,000 scientific journals. We provide a full range of services to meet all eye care needs, from the routine to the cosmetic to the surgical. All the latest content is available, no embargo periods. A number of pharmacological agents have been tested in order to enhance the patency of microvascular anastomosis and so to as extend the survival of free flaps. He graduated with honors from Tufts University School Of Medicine in 2004. The technique speed was also assessed. 2263-2272, Chirurgie de la Main, Volume 32, Issue 3, 2013, pp. After the first BTX-A infiltration, muscle twitching decreased, the ROM values increased and, according to the NDS, patients’ discomfort progressively decreased. Treatment options for muscle spasm complications of the pectoralis major (PM) flap in head and neck reconstruction have hardly been investigated. Appropriate lengths of viable structures were matched. This allows for highly precise movement in narrow and difficult-to-access spaces, and subsequently opens the door for minimally invasive surgery (Figure 1). ... Acland RD. However, prolonged anastomosis times were required when using the novel 3D-HD system rather than direct binocular vision. Degenerative histological analysis, apoptosis scoring and tissue levels of malonyl-di-aldehyde (MDA) and nitric oxide end products (NOx) were studied to understand the extent of ischaemia/reperfusion injury of skeletal muscles. Le but de cette étude est d’évaluer si l’injection d’héparine peropératoire par voie systémique ou locale permet d’améliorer le taux de survie des lambeaux libres et de justifier ainsi son utilisation d’héparine en pratique courante microchirurgicale. BTX-A infiltration is an effective non-invasive procedure that significantly reduces the PM muscular contraction in head and neck reconstruction. In the LMWH group, the patency rate was 71% (10 of 14) at both 1 and 7 days. The artery was dissected (radial or ulnar) and the vascular clamp was introduced under the skin through one of the trocarts, and then installed on the dissected artery. 2002;22(8):397-398. To subscribe to email alerts, please log in first, or sign up for a DeepDyve account if you don’t already have one. From January 2005 to May 2009, 83 patients underwent PM flap reconstruction. The office maintains state-of-the-art equipment, including digital X-rays, intraoral cameras, and the newest Zoom whitening technology. In the experimental groups, BoNT-A was applied 1 day, 7 days and 30 days before the ischaemia/reperfusion cycle. Whether you need a routine eye exam for eyeglasses or contact lenses, a medical eye exam for diabetes or other health-related issues and medications, cataract or oculoplastic surgery, eyelash enhancement with Latisse, or Botox injections, you will find excellence here.
