Challenges in management of cerebral ischemia due to Takayasu's arteritis / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the management of cerebral ischemia caused by Takayasu's arteritis.</p><p><b>METHODS</b>One hundred and three cases treated from 1984 to 2003 were reviewed including 92 females. Seven cases underwent ascending aorta to bilateral internal carotid artery (ICA) bypass, 38 cases to the axillary artery with graft to single ICA bypass. Six cases underwent ascending aorta to axillary bypass with 3 graft to single ICA bypasses as the second stage surgery. Three cases underwent ascending aorta to right ICA bypass with 2 graft to left ICA bypasses as well as 6 subclavian to carotid bypass, PTA in 5 and stenting in 3 cases, etc.</p><p><b>RESULTS</b>Twenty-seven patients with less clinical severity received conservative therapy, 9 of them had mostly temporarily improvement, 15 had slight improvement or basically no change, 1 had hemiplegia and 2 died of stroke and myocardial infarction respectively. Surgically, the short-term effective rate was 87% and operative death 7.8%. Fifty-five patients were followed up, a mean follow-up time was 48 months, and the follow-up rate was 80.9%. The excellently, good, fair, no change and death rate were 36.4%, 38.2%, 20.0%, 3.6% and 1.8% respectively. All patients with PTA or stent had an immediate good response and all recurred within 3 to 5 months.</p><p><b>CONCLUSIONS</b>For treating severe cerebral ischemia caused by Takayasu's arteritis, the ascending aorta to axillary and single ICA reconstruction or the ascending aorta-bilateral axillary bypass for patients with subclavian steal syndrome is advocated; second stage operation from graft to contralateral ICA can be carried out if necessary.</p>
