BACKGROUND: During the past decade, endovascular treatment has become the treatment of choice for all types of aortoiliac occlusive disease, including TASC C and D lesions. Patency rates, however, are still below those of open surgical techniques. One propagated technique to improve patency rates is the use of covered stents. This review assessed the available literature on covered stents for aortoiliac occlusive disease. METHODS: An extensive search was performed of the MEDLINE, Embase, and Cochrane databases...

The kidney is the third most common abdominal organ to be injured in trauma, following the spleen and liver, respectively. The most commonly used classification scheme is the American Association for the Surgery of Trauma (AAST) classification of blunt renal injuries, which grades renal injury according to the size of laceration and its proximity to the renal hilum. Arteriovenous fistula and pseudoaneurysm are the most common iatrogenic biopsy-related or surgery-related vascular injuries in native kidneys. The approach to renal artery injuries has changed over time from more aggressive intervention to more conservative observational or endovascular management, including selective transcatheter arterial embolization (TAE) and the placement of stents/stent grafts...

Development of coronary artery aneurysm (CAA) after implantation of drug-eluting stent is occasionally observed. We present a case of a 67-year-old man who underwent everolimus-eluting stent (EES) implantation in right coronary artery (RCA) for inferior wall myocardial infarction, and thereafter, giant CAAs were developed in the vessel of stent deployment, within 2 months. However, the patient was managed with coronary artery bypass grafting (CABG). On follow-up, the patient's condition was stable. To the best of our knowledge, we report the first case of occurrence of EES-associated giant CAAs in RCA subsequently treated with CABG...

The patient was a boy of 7 years and 5 months of age, who underwent LDLT for acute liver failure at 10 months of age. HV stent placement was performed 8 months after LDLT because of intractable HV stenosis. At 7 years of age, his liver function deteriorated due to chronic rejection. The patient therefore underwent living donor liver retransplantation from his father. The HV was transected with the stent in situ. The IVC was resected due to stenosis. The pericardial cavity was opened and detached around the IVC to elongate the IVC...

BACKGROUND: We describe a simple and reliable orthotopic kidney transplantation method in rats with the use of sleeve arterial anastomosis and a modified stenting technique for anastomosis of the renal vein (RV). METHODS: Male Fischer and Lewis rats were used as kidney donors and recipients, respectively, and their left kidneys were harvested in situ. In the control rats (n = 30), the renal artery (RA) and RV anastomoses were performed end-to-end with interrupted sutures by means of the conventional technique...

This study describes the development of drug-loaded nanofibrous scaffolds as a nanocoating for endovascular stents for the local and sustained delivery of rosuvastatin (Ros) and heparin (Hep) to injured artery walls after endovascular procedures via the electrospinning process. PURPOSE: The proposed hybrid covered stents can promote re-endothelialization; improve endothelial function; reduce inflammatory reaction; inhibit neointimal hyperplasia of the injured artery wall, due to well-known pleiotropic actions of Ros; and prevent adverse events such as in-stent restenosis (ISR) and stent thrombosis (ST), through the antithrombotic action of Hep...

In the age of stent deployment after balloon angioplasty. In stent restenosis (ISR) has become a major concern. Various coronary interventional measures and coronary artery bypass graft (CABG) has employed to manage the ISR. Although CABG seems to offer advantages over other coronary intervention methods in patients with multi vessel ISR; lack of appropriate graftable vessels often make the surgery difficult and end up with incomplete revascularization. Coronary endarterectomy with stent removal mitigated some of the limitations of CABG but initial results of this surgical measure were not favorable...

BACKGROUND: The evidence base for coronary perforation (CP) occurring during percutaneous coronary intervention in patients with a history of coronary artery bypass surgery (PCI-CABG) is limited and the long-term effects unclear. Using a national PCI database, the incidence, predictors, and outcomes of CP during PCI-CABG were defined. METHODS AND RESULTS: Data were analyzed on all PCI-CABG procedures performed in England and Wales between 2005 and 2013. Multivariate logistic regressions and propensity scores were used to identify predictors of CP and its association with outcomes...

BACKGROUND: Biliary complications continue to be the 'Achilles heel' of living donor liver transplantation (LDLT). The use of biliary stents in LDLT to reduce biliary complication is a controversial issue. We performed a randomized trial to study the impact of intraductal biliary stents on postoperative biliary complications following LDLT. STUDY DESIGN: Of the 94 LDLT's, that were performed during a period of 16 months, ABO incompatible transplants, left lobe grafts, ≥3 ducts on the graft and those requiring bilio-enteric drainage were excluded...

Importance: In patients with left main coronary artery (LMCA) stenosis, coronary artery bypass grafting (CABG) has been the standard therapy for several decades. However, some studies suggest that percutaneous coronary intervention (PCI) with drug-eluting stents may be an acceptable alternative. Objective: To compare the long-term safety of PCI with drug-eluting stent vs CABG in patients with LMCA stenosis. Data Sources: PubMed, Scopus, EMBASE, Web of Knowledge, and ScienceDirect databases were searched from December 18, 2001, to February 1, 2017...
