Purpose: To retrospectively review the outcomes of 21 patients with stab wounds to the gluteal region who underwent embolization for pseudoaneurysms causing active bleeding.
Materials And Methods: Between 1997 and 2007, 3 superior gluteal artery, 2 inferior gluteal artery and 16 deep femoral artery muscular branch pseudoaneurysms detected by digital subtraction angiography were selectively catheterized with diagnostic catheters with hydrophilic coating and embolized with pushable springcoils. 17 of the 21 pseudoaneurysms were located in a distal end of an artery where outflow vessels could not be depicted. The other 4 lesions were side wall injuries which required the placement of coils distal and proximal to the injury site.
Results: Embolization was successful in controlling the bleeding in all of the patients. 16 patients required 1 or 2 coils, 4 patients required 3 coils and 1 patient required 5 coils. 2 patients had femoral puncture site hematomas which resolved spontaneously. 2 patients required surgical evacuation of large gluteal hematomas following the embolization because of symptoms second to mass effect. There were no procedure related major complications or mortality.
Conclusions: Our experience demonstrates that pushable coil embolization is a relatively simple, effective and economic method for the embolization of pseudoaneurysms caused by penetrating gluteal injuries. Experimenting with other embolization materials does not seem to be justified.

Acute Necrotizing Pancreatitis Leading to Hemosuccus Pancreaticus and Hemorrhagic Shock in the Setting of Decompensated Cirrhosis.

Hemosuccus pancreaticus (HP) is a rare, life-threatening cause of upper gastrointestinal bleeding, often linked to chronic pancreatitis and pseudoaneurysm rupture into the pancreatic duct. However, its occurrence in acute necrotizing pancreatitis with decompensated cirrhosis is exceedingly rare and poses significant diagnostic and treatment challenges. We report a case of a 34-year-old male with decompensated alcoholic cirrhosis who developed hemorrhagic shock from HP following acute necrotizing pancreatitis.

Cystic artery pseudoaneurysms are a rare but life-threatening entity that commonly occurs as a sequela to acute cholecystitis. We present a case of a 52-year-old male with a past medical history of decompensated alcoholic liver cirrhosis who underwent a transjugular liver biopsy (TJLB) after correction of his baseline coagulopathy. On post-operative day one, the patient had significant blood loss with an inappropriate response to blood transfusions and without an identifiable source of bleeding.

Department of Radiology, Nippon Medical School.
As a blood flow control technique for embolization using glue (n-butyl cyanoacrylate; NBCA) for peripheral artery aneurysm/pseudoaneurysm, we placed a vascular plug or coils at the proximal inflow vessel before glue injection. We describe this maneuver, which we call the glue in lockdown technique. Four peripheral aneurysms-two pulmonary artery pseudoaneurysms, one pancreaticoduodenal arcade pseudoaneurysm, and one internal iliac artery aneurysm-deemed unsuitable for conventional embolization because of abnormal blood flow, coagulopathy, or anatomical complexity were embolized with our technique.

Introduction: The duodeno-pancreatic region is a highly vascularized area. The superior and posterior pancreaticoduodenal artery is a vessel primarily originating from the gastroduodenal artery. It exhibits rare anatomical variations, such as its emergence from the right branch of the hepatic artery, which we fortuitously identified during a cadaver dissection.
