ABSTRACT
【Objective】 To summarize a rapid and effective method to eliminate autoantibodies interference with blood group identification and evaluate its treatment effect. 【Methods】 Blood samples with suspicious results in initial blood group identification were collected, and those caused by autoantibodies were chosen, and their red blood cells were washed, dispersed or treated with sulfhydryl reagent. After allogeneic or autologous absorption of plasma, blood groups of those patients were re-detected to evaluate the effectiveness of the above method. 【Results】 Among 39 patients presenting suspicious ABO blood group, 9 were interfered by autoantibodies. After appropriate treatment, the ABO/RhD blood group of those patients could be identified. 【Conclusion】 Autoantibodies could interfere the identification of ABO/RhD blood group, and the efficiency and accuracy of blood group identification could be improved by analyzing the test results and selecting appropriate treatment methods.
ABSTRACT
Objective To retrospectively review the experience and early clinical result of carotid endarterectomy (CEA) for the treatment of symptomatic carotid artery stenosis. Method CEA was performed on 82 consecutive patients (66 males, 16 females), age ranged from 48 to 84 years (mean 68.6 years). Diagnosis was established by carotid artery Doppler ultrasonography and DSA in all patients. General anesthesia was used in 39 cases, regional anesthesia was used in 43 cases. Temporary intraluminal shunts were used in 56 patients. Results There was no surgical mortality. Postoperatively 76 patients were followed up from 4 months to 18 months. Symptoms significantly improved in 57 cases, mild improvement was achieved in 14 cases, severe postoperative complication occurred in 3 patients, including cerebral ischemia in 2 cases, intracarotid thrombosis in one. Conclusion CEA is an effective therapy for the treatment of symptomatic carotid artery stenosis.
