ABSTRACT
Coil embolization is a safe therapy for pulmonary arterio-venous malformations (PAVMs). We report the case of a 72-year-old woman affected by hereditary hemorrhagic teleangectasia who experienced right bundle branch block and atrial fibrillation 36 hours after embolization of an extended PAVM. To our knowledge, this is the first case of such a complication of embolization of a pulmonary fistula, presumably due to an acute pressure overload on both the right atrium and ventricle. This case report suggests that, after embolization of extended pulmonary fistulas, patients should be carefully monitored for rhythm disturbance and new onset of intraventricular conduction defects.

PURPOSE: To report the endovascular treatment of an intrahepatic portosystemic venous shunt (IPSVS) using a tissue adhesive solution. CASE REPORT: A 40-year-old woman without diagnosed liver disease presented for evaluation of vague abdominal pains. A latent portosystemic encephalopathy was diagnosed only during hospitalization, when ultrasound examination disclosed a venous-venous right hepatic communication. The patient was treated with selective percutaneous embolization using a tissue adhesive after blocking the lesion's venous inflow and outflow tracts. The result was excellent, and the patient recovered completely in a few days. After 5 months, the patient is asymptomatic and event-free. CONCLUSIONS: Large IPSVS may be successfully treated percutaneously using a tissue adhesive solution, avoiding a more invasive procedure.
