目的:探讨伴有高原红细胞增多症的深静脉血栓(DVT)的特点及诊断与治疗。方法:分析28例合并高原红细胞增多症的深静脉血栓形成的特点及诊断、治疗方法。结果:28例患者中有6例合并肺栓塞,占21.43%,全部病例经溶栓、抗凝治疗后均康复出院,随访期间红细胞数、血红蛋白含量、红细胞压积仍高于正常者20例,其中,复发下肢静脉血栓形成4例,动脉血栓1例,肠系膜上静脉血栓形成1例。结论:高原红细胞增多症并发深静脉血栓起病隐匿,易被忽视,且易复发,应早期诊断,抗凝治疗周期应延长。
Objective: To investigate the characteristics, diagnosis and treatment of deep venous thrombosis (DVT) associated with high altitude polycythemia. Methods: The characteristics of deep venous thrombosis in 28 patients with high altitude polycythemia and the methods of diagnosis and treatment were analyzed. Results: Among the 28 patients, 6 cases were complicated with pulmonary embolism, accounting for 21.43%. All cases were discharged after thrombolysis and anticoagulation therapy. The number of erythrocyte, hemoglobin and hematocrit were still higher than those of 20 cases during follow-up. Among them, 4 cases of recurrent lower extremity venous thrombosis, arterial thrombosis in 1 case, superior mesenteric vein thrombosis in 1 case. CONCLUSION: The pathogenesis of high altitude polycythemia complicated with deep venous thrombosis is insidious, easily overlooked, and easy to relapse. It should be diagnosed early and anticoagulant therapy should be prolonged.
