bowel stent insertion has a variety of complications one major of which is colonic perforation. the purpose of this article is to reveal two cases with delayed colonic perforation after stent placement to relieve bowel obstruction caused by rectal cancer. the first patient was a 55 year-old man who was a candidate for stent placement to avoid palliative surgery and relieve his bowel obstruction...

conclusions this nonrandomized comparison of stent types in kidney transplantation supports the use of prophylactic double-j stents in terms of decreased ureteric complications and reduced length of hospital stay. patients and methods a retrospective analysis was performed on data of renal transplantations performed at our institution in a 12-month period. in this period, external and double-j ...

The article presents our experience of observing two different approaches for endoscopic retrograde drainage in patients with malignant pathology the pancreatobiliary zone, complicated by bile duct obstruction. In one case, case dysfunction installed uncovered stent as a result incrustation salts and/or tumor invasion, stent-to-stent restenting was performed. second if it impossible to pass gui...

The Neuroform stent is a self-expanding nitinol stent designed for use in wide-necked intracranial aneurysms. Heating and imaging artifacts were evaluated by using a porcine carotid artery aneurysm model in a 3T MR system. A suspended Neuroform stent was tested for deflection. No heating was measured, and no evidence of deflection of the stent was found. Imaging artifacts were minimal. MR imagi...

introduction: this study aimed to evaluate the effects of four-time inflation of the stent balloon at nominal pressure on optimal stent expansion in resistant lesions. materials and methods: this interventional study was conducted on 39 patients with coronary artery lesions, in whom zotarolimus-eluting stents (n=20), paclitaxel-eluting stents (n=11) and other stents (n=8) were deployed four tim...

A 64-year-old man with multiple comorbidities (obesity and metabolic syndrome, dilated cardiomyopathy, type 2 diabetes mellitus, chronic renal insufficiency, obstructive sleep apnea syndrome, and colonic diverticula) underwent anterior resection for distal rectal cancer with protective ileostomy. A few days later, enteral juice was flowing from surgical drains; an urgent endoscopy with fluorosc...

Background Flow diversion (FD)-a young technique using stents with highly increased surface coverage-was introduced to treat complex aneurysms without intra-aneurysmal material placement and has amended the spectrum of endovascular techniques such as stent-assisted coil occlusion considerably. However, ischemic complications, a common side effect in FD, occur more frequently compared with the c...

Abstract. In this work we study the hemodynamics in a stented artery connected either to a collateral artery or to an aneurysmal sac. The blood flow is driven by the pressure drop. Our aim is to characterize the flow-rate and the pressure in the contiguous zone to the main artery: using boundary layer theory we construct a homogenized first order approximation with respect to ǫ, the size of the...

In the case of advanced stage gynecological disorders, most patients have a disturbance in upper urinary tract. Most with uterine cervical carcinoma are already 3B and require urine diversion. The purpose this study is to find determine profile disorders that diversion, type diverted output carcinoma. This descriptive analytical retrospective was conducted at Dr. Soetomo Hospital, Surabaya, Ind...
