rectal surgery are leaks and stenosis, which occur with a frequency of 0.3% ± 30 % [1,2]. Strictures are commonly treat− ed with conservative treatments such as balloon dilatation, endoscopic incision, and placement of self−expanding metal stent (SEMS) [3 ± 5]. Two patients with complete colorectal anastomotic closure were successfully treated with an endo− scopic±radiologic rendezvous procedur...

Stent malapposition (whether acute and persistent, or late and acquired) is common, occurring in 10–20% of drug-eluting stent implantations in stable patients and 30–40% of ST-elevated myocardial infarction patients. Acute stent malapposition is not a predictor of early stent thrombosis. Conversely, late stent malapposition, especially the large late stent malapposition area, might be a cause o...

Background: In intracavitary brachytherapy for gynecological cancers, various techniques are used to locate the anterior rectal wall nearest to the sources but there is no consensus on the best method to do so. This study aimed to compare a technique used routinely in some centers that employs a wire marker to locate the position of the maximum rectal dose point, versus the method recommended b...

Objective The underlying mechanisms of stent thrombosis are not completely understood. Methods We experienced 12 definite stent thrombosis cases (1 early, 1 late, and 10 very late) at our hospital from July 2011 to April 2016 and evaluated the possible causes of stent thrombosis by intravascular ultrasound (IVUS). Results Five different potential morphological causes of stent thrombosis (neoath...

Abstract Left subclavian artery occlusion is frequently treated by stent placement. The most commented on In-Stent Restenosis excessive thrombus that squeezes the and leads to vessel occlusion. In this paper, an automatic system provided segment left arteries aortic arches from chest MRI (Magnetic Resonance Imaging) images, then identify of based gray-levels extracted arch. Experimental results...

We thank Dr Paul D. Williams, Dr Mama A. Mamas, and Dr Douglas G. Fraser for their interest in our article. First, we investigated the stent fracture after Xience V (Abbott Vascular) and Promus (Boston Scientific). As they note, our results, therefore, do not apply to all everolimus-eluting stents. Second, they suggest that double stent strut layer shown in Figure 4 is the consequence of stent ...

Coronary aneurysms in adults are rare clinical entities. Herein, we presented a 54-year-old man who was admitted with an acute extensive anterior myocardial infarction. The emergency coronary angiography revealed an isolated large aneurysm at the proximal segment of the left anterior descending coronary artery. The patient was successfully treated with a graft-coated stent

OBJECTIVE This study was conducted to evaluate stent compression in iliac vein compression syndrome (IVCS) and to identify its association with stent patency. MATERIALS AND METHODS Between May 2005 and June 2014, after stent placement for the treatment of IVCS with acute ilio-femoral deep vein thrombosis, follow-up CT venography was performed in 48 patients (35 women, 13 men; age range 23-87 ...

Intestinal perforation from a migrated biliary stent is a known complication of endoscopic biliary stent placement. We present a case of stent migration and resultant duodenal perforation after stent placement for a malignant biliary stricture in a 52-year-old woman. We review the current literature on the diagnosis and management of stent migration and intestinal perforation after endoscopic s...
