Restenosis and stent thrombosis remain major concerns after percutaneous coronary intervention for the treatment of coronary artery disease. The present review was undertaken in order to highlight the various coronary stents that have been investigated in our Heart Research Center, and how far we have come from the first heparin-coated stent first used in the late 1990s. Thereafter, from the ab...

We report a rare case of aneurysm of splenic artery arising anomalously from the superior mesenteric artery (SMA). The aneurysm was treated successfully by coil embolization of the splenic artery distal to aneurysm and then deploying a stent graft in the SMA. A combination of stent graft and coil embolization for the treatment of aberrant splenic artery aneurysm has been reported only once. We ...

Traumatic splenic vein aneurysm (SVA) is an extremely rare entity. Traditionally, treatment varied from noninvasive followup to aneurysm excision with splenectomy. However, there has been no prior report of traumatic SVA treated with endovascular stent graft for SVA via percutaneous transsplenic access. Therefore, we report the case of a 56-year-old man successfully treated with endovascular st...

Carotid trauma demands early diagnosis and treatment. Open repair may be technically challenging if the trauma is at the base of the neck. We present a case of iatrogenic penetrating carotid trauma caused by insertion of a hemodialysis catheter. Treatment was accomplished by placement of a covered stent-graft in the common carotid artery, covering the puncture site. This case suggests that plac...

BACKGROUND Trauma-related subclavian and axillary vascular injuries (SAVIs) are generally associated with high morbidity and mortality rates in the surgical literature. There is an emerging trend towards increasing use of stent grafts (covered stents) for repair, with evidence limited to small case series and case reports. OBJECTIVES To report on the clinical and device-related outcomes of st...

BACKGROUND Access-site and access-related vascular injury (ASARVI) is still a major limiting factor in transcatheter aortic valve implantation and affects the outcome of patients. Management strategies for ASARVI include manual compression, stent grafts, and vascular surgery. We hypothesized that the standard use of a self-expanding stent graft for the management of ASARVI is feasible and safe....

pseudoaneurysm is rare, and generally occurs after a penetrating trauma rather than after blunt trauma. A bypass graft and sacrifice of the involved carotid artery was originally the treatment of choice until the advent of endovascular method. Currently, a traumatic carotidjugular fistula can be treated using endovascular methods such as ballooning, coiling, stent-graft deployment and stent ass...

Esophageal stent implantation can relieve esophageal stenosis and obstructions in benign esophageal strictures, and magnesium alloy stents are a good candidate because of biodegradation and biological safety. However, biodegradable esophageal stents show a poor corrosion resistance and a quick loss of mechanical support in vivo. In this study, we chose the elastic and biodegradable mixed polyme...

Arteriovenous grafts (AVGs) for hemodialysis have a high failure rate, often due to the development of stenosis at the graft-to-vein anastomosis. Angioplasty (PTA) has been used for over two decades to treat AVG stenosis, with good technical success but limited AVG patency. Results of a prospective multi-center randomized trial, comparing stent graft to PTA in AVGs, has demonstrated superior ac...
