Abdominal aneurysms and pseudoaneurysms represent an important finding every emergency radiologist must detect. True aneurysms are usually incidental to the presenting complaint, whereas pseudoaneurysms are nearly always symptomatic. We review the demographics, pathophysiology, clinical presentation, computed tomographic appearance, treatment approaches, and prognosis of visceral aneurysms and pseudoaneurysms involving splenic, gastroduodenal, ...

Raynaud's phenomenon is episodic vasospasm of the peripheral vessels. It presents as episodic colour changes of the digits (sometimes accompanied by pain and paraesthesia), usually in response to cold exposure or stress. The classic triphasic colour change is white (ischaemia), then blue (de-oxygenation), then red (reperfusion). Raynaud's phenomenon can be ...

Cytochrome P450 epoxygenase-derived epoxyeicosatrienoic acids (EETs) have multiple biological functions in cardiovascular homeostasis. The anti-inflammatory, anti-migratory and pro-proliferative effects of EETs suggest a possible beneficial role for EETs in the apoptosis, proliferation and migration of pulmonary vascular cells. In this study, we investigated the effects of exogenous EETs and cytochrome P450 2J2 ...

Dacron® (polyethylene terephthalate) and Goretex® (expanded polytetrafluoroethylene) vascular grafts have been very successful in replacing obstructed blood vessels of large and medium diameters. However, as diameters decrease below 6 mm, these grafts are clearly outperformed by transposed autologous veins and, particularly, arteries. With approximately 8 million individuals with peripheral arterial ...

Coronary artery bypass grafting (CABG) has been considered the standard therapy for unprotected (nonrevascularized) left main coronary disease (ULM). However, increasing experience with ULM percutaneous coronary intervention (PCI) has resulted in high procedural success and favorable early and late clinical outcomes. In particular, reduction in clinical restenosis with drug-eluting stents, ...

The extensive use of stents during percutaneous coronary intervention (PCI) is associated with concerns about their potential adverse effects. In-stent restenosis and stent thrombosis definitely significantly affect the PCI outcome. However, review of recent relevant studies suggests that stent-related problems may have been somewhat overestimated when compared to coronary artery ...
