RESUMEN
Objective To investigate the causes of and prevention for cerebral complications in perioperative period in patients with carotid stenosis. Methods The causes and treatment of cerebral complications among 133 cases of carotid stenosis during perioperative period from May 2004 to Jun 2009 were analysed retrospectively. Results Among 133 cases, 94 cases underwent carotid endarterectomy (CEA) and 39 cases had carotid artery stenting(CAS). Cerebral complications developed in 16 cases including 3 cases of more than two attacks. 5 cases suffered from tansient ischemia attacks (TIA)or cerebral ischemia before operation. 5 developed TIA or cerebral hyperperfusion syndrome (CHPS) among those undergoing CEA and 4 developed TIA or CHPS among CAS cases. During postoperative period, 8 cases developed TIA, CHPS,cerebral infarction or cerebral hemorrhage. Conclusions Prevention and treatment of cerebral complications is extremely important durning surgical therapy of carotid stenosis.
RESUMEN
Objective To evaluate the value of non invasive examinations in the diagnosis of vascular disease of lower extremity. Methods Segmental systemic pressure (SEG), pulse volume recorder (PVR) and continuous wave (CW) were adopted to examination of 36 patients with arterosclerosis obliterans of lower limbs, and the foundings were compared with that of MRA and operation . Results In all 36 cases, non invasive examinations detected abdominal aorta and common iliac artery with femoral artery occlusion in 12 cases ,femoropoplitea artery occlusion in 28 cases, popliteal artery and the distal artery occlusion in 16 case; MRA together with operation confirmed abdominal aorta and common iliac artery with femoral artery occlusion in 11 cases, femoropopliteal artery occlusion in 32 cases and popliteal artery and the distal artery occlusion in 13 cases. The accurent diagnosis rate of non invasive examination was 85.7%. Conclusions Although PVR has not yet been used to replace the arteriography to directly observe the local situation of arterial lesions , it can preliminarily determine the obstruction sites and severe degree of the occluded arteries. PVR has convenient and reliability in the diagnosis,evaluation of the therapeutic effect and the postoperative follow up of blood vessel diseases,it is worthy to be widely applied in the clinical practice.
