Salvage of Free Second Toe with Venous Thrombosis by Shunting Backflow of Second Dorsal Metatarsal Artery-A Case Report

以動靜脈分流挽救靜脈阻塞之游離腳趾-病例報告

摘要


一位二十六歲泰國男性因左手二、三、四指近位指節及大拇指節遠位指節截肢進行腳趾移植重建手術。在術中靜脈發生散在性的血栓造成腳趾嚴重充血發紺,雖然給予抗凝血藥物,情況沒有改善。在挽救手術當中發現腳趾背側的第二背側腳掌動脈有大量的動脈血回流,且腳趾充血的情況獲得立即的改善,因此我們取一段九公分的靜脈,遠端接在第二背側腳掌動脈,將回流的動脈血引流到左手背近端的靜脈,成功的挽救了充血的遊離腳趾。

A 26-year-old Thai man underwent free toe transfer for reconstruction of his left band after multi-digit amputation. Unfortunately we encountered a problem of disseminated venous thrombosis. We dissected the thrombotic veins and found that the venous network was occluded by thrombi. Surprisingly, there was a retrograde arterial blood flow in the second dorsal metatarsal artery which immediately relieved the congestion. We shunted the backflow of the SDMA (second dorsal metatarsal artery) with a vein graft and successfully salvaged the free toe.
