A 70-year-old man presented with severe pain on the right side of the abdomen for 7 days. An abdominal CT angiographic scan showed an impending rupture of a large right internal iliac artery aneurysm which compressed to a right ureter causing hydroureteronephrosis. Fornix rupture of a right duplex kidney was also detected. Selective embolization of right gluteal arteries and then ligation of th...

The accuracy and usefulness of computed flow data in an artery is dependent on the initial geometry, which is in turn dependent on image quality. Due to the resolution of the images, smaller branching arteries are often not captured with computed tomography (CT), and thus neglected in flow simulations. Here, we used a high-quality CT dataset of an isolated common iliac aneurysm, where multiple ...

Thoracolumbar spinal angiomas are typically fed by intercostal or lumbar arteries [1] and are drained exclusively by perimedullary veins [2]. Rarely, internal iliac artery branches may supply a spinal arteriovenous malformation (AVM). Epidural venous drainage has not been reported [2-4]. Only eight cases of spinal A VMs fed by internal iliac branches have been described in the literature [2, 5-...

Isolated internal iliac aneurysms are rare. Unless rupture occurs, they usually remain asymptomatic. In this paper, a patient with a ruptured internal iliac aneurysm that resulted in chronic stage hematoma causing lumbosacral plexopathy and erosion of the pelvic bony structures is presented, along with magnetic resonance imaging (MRI) and computed tomography (CT) findings. To expedite the diagn...

The authors present five cases of combined oral mucosa-mandible defects reconstructed with the vascularized internal oblique-iliac crest myoosseous free flap. This technique has many advantages compared to other conventional methods such as the radial flap, scapula flap, and fibula flap. Vascularized iliac crest flaps provide sufficient high-quality bone suitable for reconstructing segmental ma...

Surgical repair of difficult or nonunion fractures is frequently performed with autogenous bone grafts, most commonly from the iliac crest. Complications from this procedure may include vessel injury, nerve injury, pelvic instability, bowel herniation, and ileus. The authors report a case of iliac crest herniation in a patient presenting with a small-bowel obstruction 2 years after anterior ili...

A 78-year-old man presented at Eulji University Hospital due to an abdominal aortic aneurysm with maximum diameter of 52 mm, which had been increased from 45 mm over 6 months. He underwent embolization of the left internal iliac artery with vascular plug, prior to endovascular abdominal aortic repair with a bifurcated stent graft system. Unfortunately, the inserted vascular plug was maldeployed...

Leriche syndrome involves atherosclerotic occlusion of the infrarenal aorta and bilateral common iliac arteries, and the inferior epigastric artery is an important route for lower-extremity perfusion. A 65-year-old Japanese man with sigmoid colon cancer was scheduled to undergo laparoscopic colectomy, and three-dimensional computed tomography angiography was performed to detect the feeding arte...
