目的 :评价介入诊疗技术对血管性病变和恶性肿瘤的诊断和治疗价值。方法 :采用Seldinger技术动脉插管造影、药物灌注、栓塞 ;经皮穿刺活检、注射无水酒精 ,置管引流及内支架植入术对原因不明的消化道出血、肺 (肝 )结节状病灶、呼吸道大咯血、动脉血栓形成、动脉瘤、中、晚期恶性肿瘤及其并发症进行诊断和治疗。结果 :5 2 0例中属诊断性 10 3例 ,其中 ,经介入方法确诊的 97例 ,占 94.2 % ,未确诊的 6例占 5 .8% ,属治疗性 417例 ,其中有效 411例 ,占 98.6%。结论 :介入诊疗技术在血管性病变和恶性肿瘤的诊断和治疗中具有应用范围广、疗效佳、并发症少、损伤小等特点 ,在很大程度上能弥补传统诊疗技术和内外、科的不足 Objective: To evaluate the value of interventional diagnosis and treatment of vascular lesions and malignant tumors. Methods: Arterial catheterization, drug infusion and embolization were performed with Seldinger technique. Percutaneous biopsy, injection of anhydrous alcohol, catheter drainage and stent implantation were used to assess the causes of unexplained gastrointestinal bleeding, pulmonary (nodular) nodules , Massive haemoptysis of the respiratory tract, arterial thrombosis, aneurysm, advanced malignant tumor and its complications for diagnosis and treatment. Results: There were 103 cases diagnosed in 520 cases, of which 97 cases were diagnosed by interventional methods, accounting for 94.2%. Six cases were diagnosed as undiagnosed, accounting for 5.8%. There were 417 cases, of which 411 cases were effective, Accounting for 98.6%. Conclusion: Interventional diagnosis and treatment of vascular disease and malignant tumor diagnosis and treatment with a wide range of applications, good curative effect, fewer complications, less damage and other characteristics, to a large extent, make up for the traditional diagnosis and treatment technology and internal and external, lack of subjects
