Morphological vessel injury after clamping has been an important problem in vascular surgery. Although various techniques have been employed to occlude a vessel during a surgical procedure, a complete, atraumatic occlusion method has not yet been developed. In the present study, we describe use of a novel pressure-controlled and balloon-jawed vessel clamp to provide atraumatic vessel occlusion....
PURPOSE We introduce our transient vascular occlusion technique that uses a vessel loop and Hem-o-Lok clips in laparoscopic partial nephrectomy. MATERIALS AND METHODS From March 2009 to March 2011, 15 consecutive patients underwent laparoscopic partial nephrectomy. All operations were performed by a single surgeon using the transperitoneal approach. The transient vascular occlusion technique ...
BACKGROUND AND PURPOSE Time-of-flight (TOF) angiography detects embolic occlusion of arteries in patients with acute ischemic stroke due to the absence of blood flow in the occluded vessel. In contrast, susceptibility weighted imaging (SWI) directly enables intravascular clot visualization due to hypointense susceptibility vessel signs (SVS) in the occluded vessel. The aim of this study was to ...
OBJECTIVE To investigate the response of retinal vessel diameters to photocoagulation treatment and their role for the success of laser treatment in patients with retinal vein occlusion. METHODS The study included 14 patients with branch vein occlusion or macular vein occlusion. The ophthalmologic examination included best-corrected visual acuity, biomicroscopy, fundus photography, and fluore...
results prediction of the rca as culprit lesion using tierala's algorithm was 86% sensitive and 50% specific. prediction of lcx occlusion based on st-elevation ≥ 1 mm in v6 was 87% specific (p = 0.005). sum of st elevation in leads v5 and v6 more than 2.5 mm, was a good marker of lcx prediction (p = 0.044). st-elevation in v4r was 48% sensitive and 89% specific for rca prediction (p = 0.004). w...
