PURPOSE To evaluate the long-term results of embolotherapy of pulmonary arteriovenous malformations (PAVMs) in a large group of patients. MATERIALS AND METHODS Between July 1988 and August 2001, 134 consecutive patients underwent embolotherapy of PAVMs with feeding arteries larger than 3 mm or that had previously caused bleeding or systemic complications.(More)
PURPOSE To prospectively evaluate emboli detected at transcranial Doppler ultrasonography (US) and outcome of carotid angioplasty and stent placement and compare these findings in patients treated with the use of filtering cerebral protection devices (CPDs) with the findings in patients treated without the use of filtering CPDs. MATERIALS AND METHODS This(More)
PURPOSE To assess, with magnetic resonance (MR) imaging, the number and size of new brain lesions after carotid angioplasty and stent placement (CAS) and to evaluate the association of these new lesions with neurologic deficits and transcranial Doppler ultrasonographic (US) data. MATERIALS AND METHODS Seventy-two consecutive CAS procedures were performed(More)
Vorstellung einer neuen nichtinvasiven Technik zur Untersuchung der Blutgefäße: Digitale Gefäßdarstellung. Sie gestattet eine Untersuchung von Gefäßveränderungen in Kopf- und Halsbereich ohne Stationierung der Patienten. Mit der neuen Methode konnten zwei Tumoren des Glomus caroticum aufgedeckt werden. This paper reports the findings of a new noninvasive(More)
OBJECTIVE Because stents can cause vessel angulation during movement, we hypothesized that internal carotid artery (ICA) stents might lead to alterations of cerebropetal blood flow. This study assessed three-dimensional anatomy and volumetric flow rate (VFR) in the ICA in various head positions by comparing patients treated with carotid angioplasty and(More)
OBJECTIVE We describe a new method for treating ureteropelvic junction (UPJ) obstruction using a detachable inflatable stent positioned via a cystoscopic transvesicular approach. CONCLUSION Eleven patients with UPJ obstruction were treated using a detachable inflatable stent, 64% of whom experienced complete pain relief. In 82% of patients, no obstruction(More)
