吻合血管的足内侧穿支皮瓣的应用解剖与临床应用

目的 研究足内侧穿支皮瓣的应用解剖及修复手部软组织缺损的临床效果.方法 10侧成人足踝标本经胴动脉注入红色乳胶液,解剖观测足底内侧动脉穿支血管在足内侧区的分布、起源等.临床设计吻合血管的足内侧穿支皮瓣修复手部软组织缺损11例,软组织缺损面积2 cm×2 cm～9cm×4 cm.结果 足底内侧动脉向<足母>展肌和趾短屈肌肌间隙内发出2支相对恒定的足底内侧皮穿支,供养足底内侧皮瓣;向<足母>展肌和舟楔骨间隙内发出2支相对恒定的足内侧皮穿支,供养足内侧皮瓣.11例足内侧穿支皮瓣完全成活,皮瓣面积2 cm×3 cm～11 cm×5 cm.随访6～24个月,皮瓣质地优良,外形与功能恢复满意,供区愈合良好.结论 以足内侧穿支血管营养的足内侧穿支皮瓣血供可靠,质地优良,是修复手部软组织缺损的良好选择.

Anatomy and application of free medial plantar perforator flap

Objective To reports to anatomy and clinical application of the medialis pedis perforator flap. Methods The origin, course, distribution and out diameter of medial plantar perforators, which were located at the septums between the abductor hallucis muscle and the flexor digitorum brevis, and between the abductor hallucis muscle and the skeleton, were observed on 10 sides adult feet specimens perfused with red latex. 11 free medialis pedis perforator flaps were transferred for soft-tissue defect in hand. The areas of tissue defect ranged from 2 cm x 2 cm - 9 cmx 4 cm. Results The medial plantar artery sends 2 perforators with regular anatomy through the septum between the abductor hallucis muscle and the flexor digitomm bre-vis, and 2 perforators with regular anatomy through the septum between the abductor hallucis muscle and nav-icluar bone and the medial cuneiform bone. These perforators supply the medial plantar flap and medialis pedis flap respectively. All of the 11 cases of free medialis pedis perforator flap survived uneventfully. The flap areas ranged from 2 cm × 3 cm - 11 cm× 5 cm. The appearance and functional results were satisfactory with following up for 6 to 24 months. Conclusion The free medialis pedis perforator flap is a good method in repairing soft-tissue defect in hand.
