RESUMO
A case of acute thrombosis of a mechanical mitral valve prosthesis (Medtronic-Hall) in a 34 weeks pregnant woman is reported. The clinical diagnosis was confirmed by Doppler echocardiography. Emergency surgery was performed starting with a cesarean section to save the fetus, followed by an obstetric hysterectomy. Valve thrombectomy could then be safely carried out. Both, the mother and child could be rescued by this combined intervention and were discharged from the hospital without further complications.

A case of acute obstructive hydrocephalus in a patient undergoing an aortic valve replacement is presented. This condition came about as a result of massive left cerebellar hemisphere infarction, probably due to a calcific embolism from the aortic valve. The cerebrospinal fluid circulation was blocked by compression of the fourth ventricle and the Sylvius aqueduct secondary to ischemic edema. Following external ventricular drainage, the hydrocephalus resolved but a neurological deficit secondary to the cerebellar and brain stem infarction became evident. The diagnostic, prognostic and therapeutic implications of this unusual complication following cardiac surgery are discussed.
