Deep Vein Thrombosis in Combined Ankle Arthroscopy for the Anterior and Posterior Ankle Impingement Syndrome

[Introduction]The ankle arthroscopy complication rates from 7.6% to 13.6% and deep vein thrombosis (DVT) is considered as a serious complication. The risk of DVT for patients with isolated foot and ankle conditions, even with plaster cast immobilization, and the possible benefits of mechanical and chemical prophylaxis are poorly studied. Nevertheless, some studies mentioned the risk factors such as injury severity, immobilization, obesity, nonweight-bearing, hindfoot surgery, and tourniquet time.[Case Presentation]A 27-year-old male patient, smoker, and casual athlete with complaint of left recurrent painful ankle presented an anterior ankle impingement type B and a posterior impingement syndrome. In the immediate postoperative period, the patient developed a DVT as a complication of a combined ankle arthroscopy (anterior and posterior).[Conclusions]It seems that the use of prolonged tourniquet in addition to repositioning the patient may increase the risk of complications such as VTE (venous thromboembolism) and the combination was not included in any published protocol. The current study recommended the use of the Calder antithrombotic recommendations associated with the Caprini risk assessment model in order to cover a greater at-risk population.
