Major thromboses can occur in the venous system in association with central venous catheters. This usually necessitates removal of the catheter.
The effectiveness of low dose recombinant tissue type plasminogen activator (rt-PA) in combination with heparin was assessed in patients with central venous catheter associated thrombosis.
In five patients, all suffering from cancer, a 5-7 day continuous infusion resulted in complete lysis of the thrombus without complications in three. In the other two patients moderately severe haemorrhage was observed with only partial lysis, of the thrombus.
The infusion of heparin and rt-PA is potentially effective in thrombosis related to use of central venous catheters, but the risk of haemorrhage is not inconsiderable.
中心静脉导管相关的静脉系统中可能会发生严重血栓形成。这通常需要拔除导管。
评估低剂量重组组织型纤溶酶原激活剂(rt-PA)联合肝素对中心静脉导管相关血栓形成患者的疗效。
5例均为癌症患者,连续输注5 - 7天,3例血栓完全溶解且无并发症。另外2例出现中度严重出血,血栓仅部分溶解。
肝素和rt-PA输注对中心静脉导管相关血栓形成可能有效,但出血风险不可忽视。
