To evaluate the results of balloon angioplasty of 17 stenoses resulting from intracranial atherosclerosis and vasculitis.
Seventeen skull-base and intracranial lesions were dilated with a microballoon angioplasty catheter.
Initially, 16 of the 17 stenoses showed improvement at angiography. Moderate residual stenosis was found in 2 of 12 atherosclerotic lesions, both in the distal vertebral artery. Angioplasty in 1 of 12 atherosclerotic lesions caused worsening of the stenotic site, also in the distal V4 region of the vertebral artery. All but one of the patients improved clinically. However, all five lesions caused by acute vasculitis progressed to occlusion after initial improvement.
Intracranial percutaneous transluminal angioplasty is a viable nonsurgical option for the treatment of atherosclerotic vascular insufficiency, but it may not be as successful in treating lesions caused by vasculitis in the acute phase.
评估对由颅内动脉粥样硬化和血管炎导致的17处狭窄进行球囊血管成形术的结果。
使用微球囊血管成形术导管对17处颅底和颅内病变进行扩张。
最初，17处狭窄中的16处在血管造影时显示有改善。12处动脉粥样硬化病变中有2处存在中度残余狭窄，均位于椎动脉远端。12处动脉粥样硬化病变中有1处的血管成形术导致狭窄部位恶化，同样位于椎动脉的V4远端区域。除1例患者外，其他所有患者临床症状均有改善。然而，由急性血管炎引起的所有5处病变在最初改善后均进展为闭塞。
颅内经皮腔内血管成形术是治疗动脉粥样硬化性血管功能不全的一种可行的非手术选择，但在治疗急性期血管炎引起的病变时可能不太成功。
