年輕人短途飛行後亞急性深靜脈血栓形成：病例報告

Subacute Deep Vein Thrombosis in a Young Adult after a Short Flight: A Case Report

旅行者血栓症(Traveler’s thrombosis)，又稱經濟艙症候群(Economy Class Syndrome)，通常指長時間(>4小時)飛行後發生的深部靜脈栓塞(DVT)。本報告描述一名33歲男性，在三小時飛行後出現小腿疼痛與腫脹，初期使用非類固醇消炎藥(NSAIDs)治療，但症狀復發。進一步檢查發現右側膕靜脈血栓，並確診抗凝血酶III缺乏症。患者接受血管內治療後恢復良好。本案例特殊之處在於患者年輕、飛行時間短，且無凝血異常病史。預防措施包括飛行期間保持活動與充足水分。近期旅行後若出現下肢腫脹與疼痛，應警惕DVT，診斷依賴Wells評分與超音波。治療重點在預防肺栓塞及血栓後症候群，主要為抗凝治療，必要時輔以血管內介入治療。

Traveler’s thrombosis, also known as Economy Class Syndrome, typically involves deep vein thrombosis (DVT) occurring after long flights over four hours. We report a case of a 33-year-old man who developed subacute DVT after a three-hour flight, who presented with calf pain and swelling, and was initially treated with nonsteroidal anti-inflammatory drugs, but his symptoms recurred. Further investigation revealed a thrombus in the right popliteal vein and antithrombin III deficiency. Endovascular treatment was performed, and the patient recovered uneventfully. This case was unusual, as the patient was young, had a short flight, and had no history of coagulation issues. Preventive measures for traveler’s thrombosis include staying active during flights and staying hydrated. It is important to assess leg swelling and pain following recent travel for DVT. Diagnosis often involves the Wells score and ultrasound. DVT treatment focuses on preventing pulmonary embolism and minimizing post-thrombotic syndrome, primarily through anticoagulation therapy and, when necessary, endovascular procedures.
