Extracardial migration of an atrial septal defect occluder device.

Several complications have been reported regarding the percutaneous closure of secondary atrial septal defects such as erosion, thromboembolic events, arrhythmias, and endocarditis. In this report, we describe the case of a 75-year-old woman who underwent percutaneous closure of a secondary atrial septal defect with a 12 mm Amplatzer septal occluder. Six months after the uneventful implantation of the device, we manifested an asymptomatic late embolization of the device in the abdominal aorta.

Impact of hyperthermic isolated limb perfusion on tumour oxygenation in soft tissue sarcoma.

Purpose: Hyperthermic isolated limb perfusion (ILP) with recombinant tumour necrosis factor alpha (TNF) and melphalan contributes to limb-saving treatment in patients with locally advanced extremity soft tissue sarcoma (STS). This study was conducted to evaluate the dynamic changes of tumour oxygenation and temperature during ILP and their effects on treatment response.

Patients And Methods: Tumour oxygenation (pO(2)) and tumour temperature were measured by intratumourally placed O(2)-sensitive catheter electrodes in 34 patients who underwent ILP for locally advanced or recurrent STS.
