[Manifestation of popliteal aneurysm during pulse spray thrombolysis (PST)].

We report the case of a 32-year-old woman presenting with acute extremity ischemia due to thrombosis of a previously undetected popliteal artery aneurysm. The popliteal artery aneurysm was revealed by PST which was indicated for the treatment of thrombosis of the superficial femoral artery. PST was complicated by a peripheral embolism with subsequent severe extremity ischaemia. Immediate embolectomy and reconstructive vascular surgery led to a successful result. This case illustrates the diagnostic problems of a thrombosed popliteal artery aneurysm and warns of embolic complications during PST.
