Purpose: Patency of mature vascular access for hemodialysis is mostly limited by the growing stenoses leading to acute access thrombosis. The therapy of choice is usually percutaneous balloon angioplasty (PTA). However, PTA injures the vessel wall and subsequent re-stenosis develops faster than de novo stenosis. Therefore, the key is in ...

INTRODUCTION: Postmortem computed tomography can easily demonstrate gas collections after diving accidents. Thus, it is often used to support the diagnosis of air embolism secondary to barotrauma. However, many other phenomenons (putrefaction, resuscitation maneuvers, and postmortem tissue offgassing) can also cause postmortem gas effusions and lead to a wrong diagnosis ...

Coronary artery disease is the single leading cause of death in the United States. Commonly it is treated with coronary bypass grafting using the saphenous vein (SV) or internal mammary artery (IMA) as a conduit. Unfortunately, the SV has much lower patency rates compared with the IMA. Several hypotheses exist ...

BACKGROUND: Fenestrated endovascular aneurysm repair (FEVAR) is a technically challenging operation. The duration, blood loss, and risk of limb ischaemia, contrast-induced nephropathy and reperfusion injury are likely to be higher than after standard endovascular aneurysm repair (EVAR). Benefits of FEVAR over open repair may be less than those seen with ...

Objective.  Trigeminal neuralgia is rarely caused by arteriovenous malformations of the posterior fossa. Embolization of aberrant vessels can provide symptomatic relief; however, embolization is not always technically possible, and its effects can be temporary. Embolization of the nerve's blood supply could reduce its excitability and provide pain relief. Setting.  The ...
