Evaluation of cerebrovascular reserve capacity in symptomatic and asymptomatic internal carotid stenosis with transcranial Doppler.

Cerebrovascular reserve capacity (CVRC) is a hemodynamic parameter indicating the brain's capacity to overcome ischemia. Transcranial Doppler (TCD) is a useful device to measure CVRC, with high availability and low cost. The aim of the study is to investigate asymptomatic patients with affected CVRC, who could benefit from CEA.

Abdominal aortic aneurysm in association with horseshoe kidney.

We report the preoperative diagnosis and surgical treatment of an abdominal aortic aneurysm (AAA) in association with a horseshoe kidney (HSK) in a 70-year-old man. Through a median laparotomy a vascular tube graft was successfully used for repair the AAA. The extensive parenchymal isthmus overlying the aneurysm remained intact.
