Aim:
Isolated limb perfusion (ILP) is a complex vascular procedure which uses an extracorporeal circuit with high doses of cytostatic drugs and often hyperthermia for the treatment of extremity tumours. Our study investigated the incidence, treatment and subsequent outcome of vascular complications after ILP, about which little is known.
Methods:
A retrospective study was performed, in which we found 10 vascular complications after 466 ILPs (2.1%).
Results:
In eight patients, acute arterial obstruction developed in the immediate post-operative period, resulting from a thrombus at the arteriotomy site. Prompt reintervention with thrombectomy restored the circulation in all patients. One patient developed an arterial thrombus in the brachial artery due to compression of the surrounding tumour 12 days after ILP, which was successfully treated with thrombectomy and freeing the artery from the tumour. One patient was treated conservatively for digital micro-emboli. All complications occurred in women, maybe because of their generally smaller vessel size. No limbs were lost and all patients were free of any vascular problem after a median follow-up of 3.6 years.
Conclusions:
We conclude that vascular complications after ILP are rare, consist mainly of thrombosis at the arteriotomy site and can be successfully treated by prompt thrombectomy. Therefore, close observation of the peripheral circulation after ILP is necessary.
