Objective: To demonstrate the technical success and clinical follow-up after endovascular treatment of femoropopliteal segment TASC II C and D lesions.
Methods: From July 2002 to February 2007, 234 limbs in 190 patients with femoropopliteal segment TASC II C (n = 112) and D (n = 122) lesions were treated. Endovascular treatment consisted of PTA, fibrinolysis and PTA, subintimal recanalization and PTA, and finally stent graft. Patients were clinically evaluated at 30 days, 3, 6 month, and at 1 year in the outpatient setting with clinical examination and ankle-brachial indices (ABI). In the case of stent placement, additional ultrasound evaluation was performed at 12, 24, and 48 month.
Results: 49.5% of procedures were performed on patients with lifestyle-limiting claudication (IC) and 50.5% were performed for critical limb ischemia (CLI). Technical success, defined as successful recanalization and treatment of the occluded vessel, was achieved in 97% of cases. Periprocedural mortality was 3.15% and all deaths occurred in the CLI group. A follow-up 13 +/- 6 months and was achieved in 76%. During the follow-up, clinical outcome for IC group and clinical CLI group was asymptomatic 72% vs. 29.8%, symptomatic with clinical improvement 22% vs. 33.7%, and major amputation 3% vs. 23.3%.
Conclusion: The majority of claudicating patients with femoropopliteal TASC II C and D lesions will benefit from the endovascular treatment. Patient presenting CLI have a worse outcome, nevertheless the endovascular treatment can delay amputation, preserving the native vessel and does not impede surgical bypass if needed. For this reason, we consider that endovascular treatment may be the first choice treatment even in femoropopliteal TASC II C and D lesions.
