目的 探讨下腔静脉 右心房自然转流技术在下腔静脉瘤栓切除术中的应用价值。 方法 报告 4例肾或肾上腺恶性肿瘤合并下腔静脉瘤栓患者的临床资料以及术中应用下腔静脉 右心房自然转流技术行下腔静脉瘤栓切除的方法。 结果 4例转流后下腔静脉阻断时的各项血液动力学指标无明显变化。 3例肾肿瘤患者下腔静脉瘤栓及原发肿瘤完全切除 ,1例肾上腺恶性肿瘤患者下腔静脉瘤栓大部分切除。术后恢复良好 ,无并发症。 结论 下腔静脉 右心房自然转流技术是下腔静脉瘤栓切除术中安全简便、切实可行的有效方法
Objective To investigate the value of natural bypass of inferior vena cava right atrium in resection of inferior vena cava tumor thrombus. Methods The clinical data of 4 patients with renal or adrenal malignant tumor complicated with inferior vena cava tumor thrombus and the method of intracavitary right atrium bypass were retrospectively analyzed. Results There were no significant changes in the hemodynamic parameters of the inferior vena cava after 4 cases of bypass. 3 cases of renal tumor patients with inferior vena cava tumor suppository and primary tumor completely resected, 1 case of adrenal malignant tumor patients with inferior vena cava tumor suppository resection. Postoperative recovery is good, no complications. Conclusion The right atrium natural bypass technique of inferior vena cava is a safe, simple, practical and effective method in the treatment of inferior vena cava tumor thrombus
