Renal transplantation by automatic anastomotic device in a porcine model
2015
Automatic vascular staplers for vascular anastomoses in kidney transplantation may dramatically reduce the operative time and, in particular, warm ischemia time, thus increasing the outcome of transplantation. Ten pigs underwent kidney auto-transplantation by automatic anastomotic device. Kidneys were collected by laparotomy with selective ligations at the renal hilum and perfused with cold storage solution. To overcome the shortage in length of renal hilum, a tract of the internal jugular vein was harvested to increase the length of the vessels. The anastomoses were totally performed by the use of the anastomotic device. On 10 kidney transplants, nine were successful and no complications o…
Transdermal Nitroglycerine Patch: An Optional Device to Reduce Flap Venous Congestion? A Case Report
2013
ABSTRACT Sometimes in free flap there is a venous congestion without an obstruction of the venous anastomosis or other organic causes of reduction venous drainage (haematoma, seroma compressing the pedicle). In these cases the authors suggest the application of nitroglycerine patch in the congested area of the flap few hours before the surgical exploration of the anastomosis. If there is a fast improvement of the clinical feature of the flap, the surgical exploration could be avoided. The authors underline that applying the nitroglycerin patch should not be regarded in any way as a therapy of a free flap venous thrombosis but only as an useful device, an option to be taken only when the sur…

Ascending Aorta Resection and End-to-End Anastomosis: Redistribution of Wall Shear Stress Induced by a Bioprosthetic Heart Valve
2020
Although aortic resection and end-to-end anastomosis are applied to repair ascending aortic aneurysm, there is a lack of information on the late risk of post-operative complications, such as aortic dissection and aneurysmal re-dilatation. It is recognized that altered hemodynamic forces exerted on an aortic wall play an important role on dissection and aneurysm formation. We present a case in which the hemodynamic forces were investigated prior and after repair of an ascending aorta treated by resection with end-to-end anastomosis and a bioprosthetic heart valve. Post-operative wall shear stress was redistributed uniformly along the vessel circumference, and this may suggest a reduced risk …
Applied Anatomy of the Cerebral Arteries
1991
Four arteries supply the brain with blood: the two carotid and the two vertebral arteries. Although these four vessels are ultimately interlinked via a basal arterial network, the circle of Willis, and anastomoses at the brain surface, Heubner’s anastomoses, it is useful to distinguish anterior (carotid anterior and middle cerebral) and posterior (vertebrobasilar posterior cerebral) vascular territories (Gillian 1957, 1968; Lazorthes 1961; Kaplan and Ford 1966; Ganshirt 1972; Seeger 1978; Dorndorf 1983; Duus 1983).
SULL'IMPIEGO SPERIMENTALE DI UN COLLANTE BIOLOGICO NELLE ANASTOMOSI INTESTINALI NEL RATTO IN ACCRESCIMENTO
1980
The problems that arise in the preparation of the anastomoses of channelicular organs have not found a unique solution. In fact, when it is necessary to proceed to the synthesis of very small gauge hollow organs as in the accreting subjects (infants) the risk of formation of a stenosis is always present despite the various techniques practiced. In recent years several experimental researches have been carried out in order to verify the validity of biological adhesives in intestinal anastomoses in rapidly growing animals. For this purpose we have chosen the rat whose rapidity of somatic growth permits an evaluation in times contained
Fugas de sutura en anastomosis ileocólicas. Análisis de una serie institucional y metaanálisis comparativo entre anastomosis manuales y mecánicas
2020
Objetivo: Evaluar la técnica quirúrgica (manual frente a mecánica) como factor de riesgo de fuga anastomótica (FA) ileocólica en una serie institucional, así como en el conjunto de la literatura científica publicada sobre el tema hasta el momento mediante un metaanálisis. Métodos: Análisis retrospectivo de 477 pacientes con anastomosis ileocólicas realizadas desde noviembre de 2010 a septiembre de 2016 en un hospital terciario. Las anastomosis se realizaron mediante técnicas estandarizadas. Se evaluaron los factores de riesgo independientes para FA, las complicaciones y la mortalidad. Las FA fueron divididas en menores o mayores según la necesidad de tratamiento médico o tratamiento invasiv…
Procalcitonina y proteína c-reactiva como marcadores precoces de fuga anastomótica en cirugía colorrectal
2013
Objetivo: Evaluar si la procalcitonina (PCT) y la proteína C-reactiva (PCR) son buenos predictores de fuga anastomótica en cirugía colorrectal. Métodos: Se analizaron prospectivamente 205 pacientes consecutivos operados de forma programada en cirugía colorrectal a los cuales se les realizó una anastomosis intestinal. Se registraron los datos demográficos y quirúrgicos, ASA, POSSUM y las complicaciones postoperatorias. En los primeros cinco días tras de la intervención se realizó analítica diaria incluyendo hemograma, bioquímica, PCR y PCT y se registraron las constantes vitales. Las fugas anastomóticas fueron divididas en menores o mayores según la necesidad de tratamiento médico o tratamie…
