Nitinol self-expanding stents are increasingly used to treat symptomatic peripheral arterial disease. Despite reduction in procedural complications and rates of stent fracture, femoropopliteal in-stent restenosis (FP-ISR) remains a common and important clinical problem. Due to heterogenous patient and angiographic characteristics, treatment of FP-ISR continues to evolve. Multiple modalities have been ...

Mitral valve operations are increasingly performed through minimally invasive approaches such as the right anterior minithoracotomy. To facilitate exposure with this technique, a diaphragmatic suture may be implemented. We describe a liver laceration caused by the diaphragmatic suture in minithoracotomy mitral repair and its successful nonoperative management with arterial embolization.

Endovascular approach is now the first option for the treatment of most intracranial aneurysms (IA). However, remaining limitations are the suboptimal stability of aneurysm occlusion and the treatment of complex IA. The use of conventional and flow diverter stents has partially addressed these limitations. Nevertheless, as intraluminal devices, stents require ...

Cryptogenic (of unknown cause) ischaemic strokes are now thought to comprise about 25% of all ischaemic strokes. Advances in imaging techniques and improved understanding of stroke pathophysiology have prompted a reassessment of cryptogenic stroke. There is persuasive evidence that most cryptogenic strokes are thromboembolic. The thrombus is thought to originate ...

Surgical clipping for upper basilar artery (BA) trunk aneurysms has become less common since the popularization of endovascular therapy. However, when endovascular therapy is not feasible, direct open surgery is still the treatment of choice. The anterior transpetrosal approach (ATP) is most often used to safely treat these aneurysms. We ...

Abdominal aortic aneurysm (AAA) is a chronic inflammatory disease affecting 4-8% of men older than 60 years. No pharmacologic strategies limit disease progression, aneurysm rupture, or aneurysm-related death. We examined the ability of rapamycin to limit the progression of established experimental AAAs. AAAs were created in 10-12-week-old male C57BL/6J mice ...
