title: Stenting treatment for intra- and extra-cranial atherosclerotic diseases.
abstract: The purpose of this study was to investigate the effect, safety and short-term outcome of stenting treatment for extra- and intra-cranial atherosclerotic diseases. Forty-one patients underwent stenting treatment using coronary and biliary stents. Eleven patients had tubular or diffuse high-grade stenoses not amenable to standard balloon angioplasty involving intra-cranial arteries, while in thirty, extra-cranial arteries were involved. Stents were successfully implanted in 36 out of 41 lesions (88%) with 2% (1/41) of overall procedural morbidity rate. Procedural and clinical success rate of intra-cranial stent placement was 64% (7/11) and no complications occurred during or after intra-cranial stent placement: the morbidity rate was 0%. Hyperperfusion injury occurred in two patients after successful implantation of stents in subtotal occlusion of the internal carotid artery, and consequently the overall clinical success rate was 80% (33/41). Restenosis occurred in four (12%) out of 33 patients who underwent six month follow-up arteriography. No ischemic attacks or stent-deformation occurred during follow-up after stenting treatment. For lesions not amenable to standard balloon angioplasty, endovascular stent placement seems to be a safe and effective treatment of modality.
