Early rethrombosis in femoropopliteal occlusions treated with percutaneous transluminal angioplasty.
One hundred and thirty-seven consecutive percutaneous transluminal angioplasties (PTA) were performed for femoropopliteal vascular disease including 58 stenoses and 79 total occlusions. Nine occlusions could not be crossed with the guidewire, but in the remaining 128 the haemodynamic and clinical success as well as vascular patency were evaluated. The results were grouped into the following subsets: the indication for PTA, the severity of the vascular lesion, the crural run-off and the length of lesion. The results were in every respect poor with total occlusions when compared with stenoses. This was explained by a high incidence (41%) of rethrombosis within hours of dilatation. Early rethrombosis was seen with all lengths of occlusion (1-27 cm) with no statistically significant difference from other subsets. This study concludes that conventional PTA in femoropopliteal occlusions should be reserved for cases of limb salvage, preferably in patients who are technically inoperable. We suggest a new technique of segmentally enclosed thrombolysis to prevent early rethrombosis after PTA in femoropopliteal occlusions.
