Case Summary. A popliteal artery entrapment syndrome and subsequent bypass surgery could cause severe, hard, fibrous occlusion of the native popliteal artery. Endovascular therapy that opens the native vessel is important to keep patency. It was impossible to advance the antegrade wire, as the entry of the native artery was not found by angiography or intravascular ultrasound imaging, making re...

The aim of this paper was to report on further experience with a new technique for reanimation of the facial nerve. This procedure allows a straight end-to-side hypoglossal-facial anastomosis without interruption of the 12th cranial nerve or the need for graft interposition. It is technically demanding and time consuming but offers an effective, reliable, and extraordinarily quick means of rein...

BACKGROUND Side clamping to perform saphenous vein-to-aorta proximal anastomosis is a well known cause of cerebral embolization during coronary bypass surgery. Automatic and manual devices have been introduced to avoid aortic clamping and facilitate proximal anastomosis but the manual ones only allow the traditional hand-sewing running suture. Nevertheless, they are not easy to use and very exp...

Introduction: Esophageal cancer is a common gastro intestinal malignancy. One of the most common techniques of surgery in esophageal cancer is transhiatal esophagectomy with esophagogastric anastomosis in the neck. This technique is accompanied by complications like chronic gastero-esophegeal reflux and late stenosis. This study was designed to compare the risk of complications after two surgic...

We investigate how a straight skeleton can be used to approximate a motorcycle graph. We explain how to construct a planar straight-line graph G such that the straight skeleton of G reveals the motorcycle graph of M , for every given finite set M of motorcycles. An application of our construction is a proof of the Pcompleteness of the construction problem of straight skeletons of planar straigh...

A fast, easy anastomotic technique with a high patency rate would facilitate the development of microvascular surgery. This article describes a new nonsuture method of end-to-side microvascular anastomosis using a soluble polyvinyl alcohol (PVA) T-shaped tube as an internal stent and plastic adhesive. Two kinds of T-shaped tubes were used: Type I tube had a short straight tube connected to a lo...

background in this study, given the importance of gastrointestinal anastomosis in surgical procedures, attempts have been made to compare the results of employing magnetic compression anastomosis and magnetic coils in intestinal anastomosis of rats. materials and methods this study was an experimental trial on 60 rats which had been randomly divided into two experiment (30) and control (30) gro...
