Background
Localized popliteal artery occlusion (LPAO) is a rare entity with a challenging therapy.
In selected patients, open popliteal endarterectomy (OPE) with infrapopliteal balloon
angioplasty (IPA) can be limb-saving. The aim of this retrospective study from Iraq-Kurdistan
is to assess the procedure outcomes.
Methods
Over 5 years, ending at 2020, 28 patients with atherosclerotic LPAO unsuitable for
femoropopliteal bypass or endovascular intervention received OPE + IPA through a medial
approach under spinal anesthesia. Perioperative data were obtained from patients’
records and entered into an Access database. Results were retrieved and statistically
analyzed.
Results
There were 18 (64.3%) males. The mean age was 66.4 ± 6.53 years (range 52–79 years).
Seventy five percent of patients had obesity, diabetes mellitus, and smoking. Twenty
six (92.9%) of patients were in Rutherford category 5 and 6 with an ankle-brachial
index < 0.40. Popliteal and pedal pulses were absent in 23 of 24 (95.8%) patients.
Doppler ultrasound showed a good distal runoff in 1 (3.6%) patient. Computed tomography
angiography revealed 20 (71.4%) femoropopliteal and 16 (57.1%) infrapopliteal lesions
of types A and B as per Trans-Atlantic Inter-Society Consensus II document. Mean endarterectomy
length was 5.1 cm (range 3–7), patched with a vein in (17, 60.7%) and primarily closed
in (11, 39.3%) patients. Early complications were none in (18, 64.3%) patients whereas
1 leg was amputated on day 30. On average, follow-up lasted 3.4 years. Twenty seven
(96.4%) vessels remained patent and 2 (7.1%) patients died.
Conclusions
Our study confirms safety and efficacy of OPE + IPA for selected patients with critical
limb ischemia due to LPAO.
