Two Broviac catheters were placed simultaneously in 93 patients who required prolonged intravenous support while receiving chemotherapy or a bone marrow transplant. The technique involved two venotomies in a single vein and was performed under local anesthesia in the operating room. Pancytopenia was not considered a contraindication. Blood sampling and intensive treatment with blood products, chemotherapy, parenteral nutrition and multiple antibiotics were facilitated by these durable, well-tolerated Silastic catheters. Patients were taught to care for them following discharge, and the majority of catheters were used for outpatient treatment. The few complications encountered were compensated for by the convenience and safety of the double Broviac method. The danger of chemotherapy extravasation was completely obviated, as were the complications of repeated central line insertion, and the anxiety and pain associated with multiple unsuccessful attempts at venipuncture. Because of the enthusiastic acceptance of long term Silastic catheters by patients and nursing staff, we regard this technique was a step forward in solving the problem of difficult vascular access in cancer patients.
在93例接受化疗或骨髓移植且需要长期静脉支持的患者中，同时置入了两根 Broviac 导管。该技术涉及在一条静脉上进行两次静脉切开术，在手术室局部麻醉下进行。全血细胞减少不被视为禁忌证。这些耐用且耐受性良好的硅胶导管便于进行血液采样以及使用血液制品、化疗药物、肠外营养和多种抗生素进行强化治疗。患者在出院后学会了如何护理导管，大多数导管用于门诊治疗。双 Broviac 方法的便利性和安全性弥补了所遇到的少数并发症。化疗药物外渗的风险完全消除，反复中心静脉置管的并发症以及多次静脉穿刺失败相关的焦虑和疼痛也得以避免。由于患者和护理人员对长期硅胶导管的热情接受，我们认为这项技术是解决癌症患者血管通路困难问题的一大进步。
