[Choice of hybrid interventions for iliac-femoral arterial lesions]

To compare the short-term and long-term outcomes of hybrid interventions after various infrainguinal reconstructions (restoration of blood flow through superficial femoral artery and pulsatile blood flow through deep femoral artery) in patients with iliac-femoral arterial disease.

A retrospective analysis included patients after hybrid iliac-femoral interventions between 2014 and 2018. These interventions included stenting of iliac arteries and various open infrainguinal reconstructions. The first group (n=41) consisted of patients who underwent reconstruction of superficial femoral artery, the second group (n=88) - restoration of pulsatile blood flow in deep femoral artery. We analyzed the Rutherford score, perioperative complications, primary patency rates and limb salvage rates after 12 months in both groups.

Significant improvement (Rutherford score +3) was achieved in 28 (70%) and 14 (15.9%) patients, respectively (p<0.05). There were no significant between-group differences in the number of postoperative complications. Surgery time was longer in the first group (median 160 and 130 min, respectively, p<0.05). However, intraoperative blood loss was similar. Primary patency rates after 12 months were 82.4% and 95.1%, respectively (p=0.054). Limb salvage rates after 12 months were 94.7% and 100%, respectively (p<0.05).

This study highlights the potential advantages of restoring pulsatile blood flow through the deep femoral artery in hybrid interventions. Higher primary patency and limb salvage rates in the second group indicate better long-term outcomes after restoration of blood flow through the deep femoral artery. Further prospective studies are needed to confirm these results and determine the underlying mechanisms of differences.
