Abstract:
OBJECTIVE:To explore the effectiveness of primary interventional revascularization combined with secondary perforator composite flap in the treatment of peripheral arterial disease (PAD) accompanied by soft tissue defects around the ankle.
METHODS:Between January 2022 and January 2025, 12 patients with PAD and soft tissue defects around the ankle were admitted. Among them, there were 9 males and 3 females; their ages ranged from 52 to 82 years, with an average of 68.9 years. The causes of injury included 4 cases of traffic accident, 5 cases of falls, 1 case of falling from height, 1 case of foreign body puncture injury, and 1 case of electric shock injury. The infection duration ranged from 1 month to 35 years, with a median duration of 3.5 months. The wound size ranged from 5.5 cm×3.0 cm to 15.0 cm×9.0 cm. The ankle-brachial index (ABI) was 0.32±0.12. The visual analogue scale (VAS) score for pain was 3.3±0.5. Preoperative vascular stenosis assessment was performed in all patients, with primary intervention to dredge large and medium-sized arteries, followed by secondary repair of the wound using a perforator composite flap. The flap size ranged from 6.5 cm×4.0 cm to 16.0 cm×10.0 cm. The donor sites were sutured directly or repaired with skin grafts. After two stages of treatment, the effectiveness was evaluated by measuring ABI, observing flap survival and wound healing, assessing VAS scores, and American Orthopedic Foot and Ankle Society (AOFAS) scores.
RESULTS:All 12 cases completed two stages of treatment; all patients were followed up after the second-stage treatment, with a follow-up period ranging from 7 to 28 months, with an average of 16.8 months. After the first-stage treatment, the skin temperature around the ankle was significantly higher than that before treatment, and the ABI increased to 0.71±0.07, with a significant difference ( t=9.918, P<0.001). After the second-stage treatment, the blisters on the distal end of the skin flap occurred in 3 cases. The flaps survived and the wounds healed, with a healing time ranging from 10 to 14 days (mean, 11.8 days). The incisions at the donor site healed by first intention, and the skin grafts survived. The VAS score was 0.5±0.5 at 3 weeks, which was significantly lower than that before treatment ( t=13.675, P<0.001). No infection recurrence occurred during follow-up. At 6 months after the second-stage treatment, the AOFAS score of the ankle joint ranged from 92 to 97, with an average of 94.7, all reaching excellent.
CONCLUSION:Interventional revascularization combined with perforator composite flap for staged treatment of PAD with ankle soft tissue defects can obtain good effectiveness, by unclogging the main blood vessels, improving lower limb blood supply, and improving the survival rate of the skin flap.
