To identify the optimal monochromatic energy of the dual energy spectral CT Angiography (CTA) of celiac artery with high image quality. 32 patients were tested by the contrast-enhanced CT with the dual energy spectral imaging mode. Based on the polychromatic data, images of celiac artery were reconstructed at the optimal monochromatic energy, 70 keV monochromatic energy level and the 140 kVp tu...

Celiac artery aneurysms are rare and usually asymptomatic. The management of these aneurysms is challenging, especially when they are large and involve the confluence of the trifurcation. We present here a case of a large celiac artery aneurysm involving its branches in a young woman. Preoperative investigations, intraoperative findings, and the operative procedure are also presented and discus...

A 50-year-old man presented with an acute type A aortic dissection with an aberrant right subclavian artery. Emergent total arch replacement with an elephant trunk was performed. Intraoperatively, the origin of the aberrant right subclavian artery could not be resected because it was located too far from the distal arch. After two weeks, the patient became aware of dysphagia. Postoperative comp...

The knowledge of the vascular anatomy of the concerned region is an important prerequisite for planning surgical intervention. The awareness of the existing vascular anomalies enhances the insight regarding that region. We report a patient undergoing preoperative evaluation with CTA finding of Superior Mesenteric Artery (SMA) originating from the celiac artery. This celiac-mesenteric trunk is r...

Aortopulmonary fistula is an uncommon but often fatal condition resulting as a late complication of an aortic aneurysm. The most common cause is erosion of a false aneurysm of the descending thoracic aorta into the pulmonary artery, resulting in the development of a left-to-right shunt and leading to acute pulmonary edema and right heart failure. We report an our experience with aortopulmonary ...

introduction: the persian squirrel (sciurus anomalus) is considered the only well-known species of the family sciuridae in the middle east. since some people keep this squirrel as a domestic pet, their attendance at veterinary clinics is increasing. so far, no study has been conducted on the arterial supply of the pelvic cavity and limb in the squirrel. hence, this research was performed to fil...

1 of 2 DESCRIPTION A 39-year-old man presented with sudden back pain and admitted. The contrast-enhanced CT showed the development of acute aortic dissection (AD) with patent false lumen. The dissection extended from just distal at the left subclavian artery to bilateral common iliac artery. The patient was treated with intensive blood pressure (BP) control with antihypertensive drugs, however ...

Patients with celiac artery stenosis often remain asymptomatic due to formation of extensive collateral pathways. Hepatic or anastomotic ischemia may occur when the gastroduodenal artery and these collaterals are ligated during pancreaticoduodenectomy. Here, we present a patient with severe atherosclerotic disease of the celiac axis who successfully underwent pancreaticoduodenectomy with aorto-...

We describe 2 cases of patients with loss of hepatic arterial flow during surgery for pancreatic head cancer due to celiac stenosis caused by median arcuate ligament compression. The first case underwent pylorus-resecting pancreatoduodenectomy for pancreatic head cancer. After resection of the gastroduodenal artery, flow in the common hepatic artery disappeared, and celiac axis stenosis was ide...

Celiac artery (CA) stenosis is a relatively common finding in patients undergoing pancreaticoduodenectomy (PD). In the presence of CA stenosis, arterial blood supply to the celiac territory is usually sustained from the superior mesenteric artery (SMA) through well-developed collaterals. In this paper, the authors report endosonographically identified prominent gastroduodenal artery as the sign...
