Nonatheromatous Popliteal Artery Disease.

OBJECTIVE

Peripheral artery disease (PAD) is often caused by atherosclerosis. However, causes other than atherosclerosis is often overlooked. Popliteal artery entrapment syndrome (PAES) and popliteal artery adventitial cystic disease (PACD) are two common nonatheromatous causes of claudication and critical limb ischemia. The purpose of this study is to present early results of treatment of PAES and PACD involving the lower limbs.

METHODS

From December 2019 to February 2021, 10 patients with PAES underwent surgeries, and 1 patient with PAES received conservative treatment. 2 patients with PACD underwent surgery. Patient data including age, gender, etiology of vascular pathology, diseased vessel, surgical method, and hemodynamic status were collected retrospectively.

RESULTS

The mean follow-up duration was 5.64 ± 3.72 months (range, 1-12 months). All patients had their symptoms improved or resolved. The success rate of surgery was 100%, the rate of freedom from reintervention for any reason was 100%. There were no death, bleeding, embolism, or skin ulcers during late follow-up.

CONCLUSIONS

PAES and PACD require early diagnosis and intervention, and early surgery may lead to good early- and mid-term results.
