Case ReportsTraumatic inferior gluteal artery pseudoaneurysm and arteriovenous fistula managed with emergency transcatheter embolization.
We present a case of blunt trauma to the buttock resulting in an inferior gluteal artery pseudoaneurysm and arteriovenous fistula. The characteristic diagnostic features on CT angiography and digital subtraction angiography (DSA), along with the emergency percutaneous management of this traumatic vascular injury, are described. A review of the literature demonstrates inferior gluteal artery pseudoaneurysm is a rare condition, while successful treatment with glue embolization is previously unreported.

Case ReportsInterventional management of massive hemothorax due to inadvertent puncture of an aberrant right subclavian artery.
We report a case of massive hemothorax due to inadvertent puncture of an aberrant right subclavian artery during central venous access. Iatrogenic laceration at the origin of the right internal thoracic artery was successfully treated with coil embolization of the internal thoracic artery followed by stent-graft placement into the subclavian artery. Due to its elongated and abnormal course, an aberrant right subclavian artery may predispose to inadvertent puncture during vein catheterization and should be recognized as a potential threat for such procedures. Our case emphasizes that ultrasound guidance should be used routinely for central venous lines wherever possible.

Large-bore gastrostomy feeding tube insertion by a pull technique using a snare.
We describe a series of three patients who had fluoroscopic-guided placement of a large-bore gastrostomy tube using a pull technique and a large snare placed via a nasogastric or orogastric tube.

Endovascular therapy of ruptured abdominal aortic aneurysm: mid- and long-term results.
As an alternative to open aneurysm repair, emergency endovascular aortic repair (EVAR) has emerged as a promising technique for ruptured abdominal aortic aneurysm (rAAA) within the last decade. The aim of this retrospective study is to present early and late outcomes of patients treated with EVAR for rAAA. Twenty-two patients (5 women, 17 men; mean age, 74 years) underwent EVAR for rAAA between November 2000 and April 2006. ⋯ The overall mortality rate in our study group was 36%. EVAR is an acceptable, minimally invasive treatment option in patients with acute rAAA, independent of the patient's general condition. Short- and long-term outcomes are definitely comparable to those with open surgical repair procedures.
