Innominate Artery Dissection Caused by Video-Mediastinoscopy.

Mediastinoscopy is considered a safe technique to biopsy mediastinal lesions. Among its complications, vascular ones are the most common. We present a rare case of intimal dissection of the innominate artery during the performance of a mediastinoscopy that caused an ischemic attack from which the patient recovered completely without long-term sequelae.

Acute renal infarction: Clinical characteristics and prognostic factors.

Introduction: Acute renal infarction (ARI) is an uncommon disease, whose real incidence is probably higher than expected. It is associated with poor prognosis in a high percentage of cases.

Objectives: To describe the main clinical, biochemical and radiologic features and to determine which factors are associated with poor prognosis (death or permanent renal injury).
