[Xenopericardial femoral artery surgery in hybrid treatment of critical ischemia of the lower extremities].

OBJECTIVE

To compare 6- and 12-month results of femoral artery repair with xenopericardial and autologous venous patch in hybrid treatment of critical lower limb ischemia.

MATERIAL AND

METHODS

A retrospective analysis included 60 patients with critical lower limb ischemia who underwent hybrid treatment (balloon angioplasty and stenting of iliac arteries and open reconstruction of femoral arteries). Patients were divided into 2 groups by 30 people depending on femoral artery repair (group 1 - autologous venous patch, group 2 - xenopericardial patch). Postoperative complications, symptoms of critical ischemia, ankle-brachial index and pain-free walking distance were assessed after 6 and 12 postoperative months.

RESULTS

Postoperative complications occurred in 3 (5%) patients. In 1 case (pulsating hematoma), they were associated with endovascular intervention, in 2 cases (bleeding and lymphorrhea) - with surgical intervention. After 6 months, resting pain and trophic disorders disappeared. Moreover, pain-free walking distance increased in both groups. The ankle-brachial index increased by 1.8 and 1.9 times compared to preoperative data in each group, respectively. After 12 months, femoral artery restenosis occurred in 2 patients of the 1st group.

CONCLUSION

After 6 months, there were no significant between-group differences. After 12 months, xenopericardial patch was superior to autologous venous patch.
