Renal nutcracker syndrome is an anatomic anomaly characterized by the compression of the left renal vein between the superior mesenteric artery and the aorta or between the aorta and the vertebral body. Diagnosis is often challenging. Common presenting symptoms include hematuria, abdominal pain, and pelvic congestion. Several open and endovascular techniques have been described to treat this sy...

A veia renal esquerda (VRE) se localiza anteriormente à artéria aorta abdominal e posteriormente mesentérica. Essa posição favorece a compressão da VRE, fato que tem como consequência manifestação síndrome do quebra nozes (SQN). Contudo, presença de uma variação anatômica extremamente rara na qual VRE assume retroaórtica apresenta um possível fator preventivo SQN. Assim, esta revisão literatura...

Introduction: Aneurysmal degeneration in patients with chronic type B dissection is common, occurring 20% – 40% of cases, which 10% develop late rupture. Open surgery for these cases associated high morbidity and mortality. Endovascular alternatives include fenestrated or branched endografts, although the use devices may be complex. Treatment usually involves implantation a device true lumen ob...

Variations in the urogenital vascular anomalies in the abdomen are very common. However, they warrant attention due to their importance in operative, diagnostic, and endovascular procedures. During routine dissection of abdomen in a male cadaver, unique urogenital vascular anomalies were observed. On the right side, the right renal artery was found to be originated from the abdominal aorta at t...

A 14-year old male with no previous medical history presented with headache, left third cranial nerve palsy, and generalized tonic-clonic seizures. Magnetic resonance imaging of the brain revealed subarachnoid hemorrhage secondary to an aneurysm of the left posterior communicating artery. The patient underwent successful transcatheter coil occlusion of the aneurysm, and his neurological symptom...

Variations of the arterial and venous system of the abdomen and pelvis have important clinical significance in hepatobiliary surgery, abdominal laparoscopy, and radiological intervention. A case of double inferior vena cava (IVC) with complex interiliac communication and variation of the common hepatic artery (CHA) arising from superior mesenteric artery (SMA) in a 79-year-old male cadaver is p...

A 73-year-old man with a history of hypertension and ascending aortic dissection was hospitalized for aggravated abdominal pain and general ache for 3 months. Follow-up CT showed aggravated abdominal aortic hematoma with aneurysm, atherosclerotic periaortitis and bilateral hydronephrosis. An initial laboratory finding showed elevated levels of inflammatory markers and renal dysfunction. Positro...

The aim of this study was to analyze the anatomical characteristics of patients with ruptured abdominal aortic aneurysms (AAAs) using computed tomography (CT) aortography in order to determine the risk factors for rupture.We retrospectively reviewed the CT aortography findings and medical records of patients with ruptured AAAs who underwent CT aortography between February 2002 and December 2014...

OBJECTIVE To determine whether there is a relation between aortic diameter and morbidity and mortality in men screened for abdominal aortic aneurysm. DESIGN Prospective cohort study. SETTING Highland and Western Isles (a large, sparsely populated area of Scotland). PARTICIPANTS 8146 men aged 65-74. MAIN OUTCOME MEASURES Morbidity and mortality in relation to presence of abdominal aortic...
