Background: The treatment strategy for patients with multiple infrapopliteal artery occlusions remains controversial. In this study, we investigated how anatomic factors affect the treatment effect of infrapopliteal artery intervention and identified suitable intervention strategies for patients with multiple infrapopliteal artery occlusions. Methods: This was a prospective, single-center, observational cohort study. For each patient, the intrainterventional blood volume improvement of the dorsum and plantar surface was measured and classified into the direct perfused region (DR) or indirect perfused region (IR) on the basis of whether the supplying artery was revascularized. Digital subtraction angiography was performed to analyze how pedal arch patency affects blood communication between DR and IR. Results: A total of 38 patients treated with infrapopliteal intervention at the Department of Vascular Surgery of Peking Union Medical College Hospital from November 2016 to November 2020 were considered for inclusion in this study. Finally, 26 patients were included in the analysis. In patients with type III pedal arch, blood volume improvements for DR and IR were 70.50 (17.50, 191.75) and 11.25 (-10.25, 50.25) mL/1,000 mL, respectively (P=0.018). No significant difference was found between DR and IR in patients with type I pedal arch (P=0.208) and type II pedal arch (P=0.110). Conclusions: Impaired pedal arch has an adverse impact on foot collateral circulation. Patients with these conditions are more suitable for direct revascularization than other patients.
