Limited vascular access hinders administration of chemotherapy, blood products and antibiotics in cancer patients. Repeated venous cannulation is often psychologically traumatic to patients. The use of a subcutaneous infusion port allows convenient vascular access. Twenty-two cancer patients had ports implanted for venous access (17 patients) and administration of regional chemotherapy (5 patients). The period of indwelling ranged from 70 to 470 days (median 270 days). Two patients (9%) had wound dehiscence that required port revision. Despite this, the wound did not heal in 1 patient and the port had to be removed. Other complications included venous thrombosis (5%) and subcutaneous haematoma (5%). There was no catheter-related bacteraemia. The subcutaneous infusion port provides a suitable vascular access in cancer patients.
血管通路受限会妨碍癌症患者化疗、血液制品及抗生素的给药。反复静脉插管对患者而言往往会造成心理创伤。皮下输注端口的使用可提供便捷的血管通路。22例癌症患者植入了端口用于静脉通路（17例患者）及区域化疗给药（5例患者）。留置时间为70至470天（中位值270天）。2例患者（9%）出现伤口裂开，需要对端口进行修复。尽管如此，1例患者伤口未愈合，不得不移除端口。其他并发症包括静脉血栓形成（5%）和皮下血肿（5%）。未发生与导管相关的菌血症。皮下输注端口为癌症患者提供了合适的血管通路。
