Latrogenic aortic dissection during mitral valve replacement surgery--a case report.

Intraoperative aortic dissection is one of the complications of aortic cannulation, which is potentially lethal with an incidence of about 0.16%. Early diagnosis and treatment can lower the mortality rate effectively.

Cerebral arteriovenous malformation diagnosed during labor induction with headache and convulsions as presentations--a case report.

The occurrence of complications of intracranial arteriovenous malformation (AVM) during labor induction is relatively uncommon. Intracranial AVM can cause convulsions, headache, focal neurological deficits and intracranial hemorrhage if ruptures. We present a 33-year-old parturient with history of paroxysmal supraventricular tachycardia, who was admitted for labor induction.
