Majority of human animal-related injuries in the United Arab Emirates are caused by camels. These may involve major vessels and can be life-threatening. We aimed to study the biomechanism, injured regions, management, and outcome of major camel-related human vascular injuries.
We retrospectively studied all patients who were admitted to Al-Ain Hospital with camel-related major vascular injury during January 2001 to January 2020. Studied variables included demography, mechanism of injury, injured structures, clinical presentation, vital signs on arrival, associated injuries, surgical management, ICU stay, length of hospital stay, complications, and outcome.
Seven patients were studied; all were males having a median age of 26 years. Five out of six bite injuries (83%) occured during the camel rutting season. The injuries were severe and life-threatening. A camel bite causes four small elliptical wounds of the canine teeth which resembles two stab wounds of 8 cm long, penetrating deeply and injuring major vessels. Four involved the carotid artery, one the femoral artery and vein, one the external iliac vein and one the aorta which was due to a fall from a camel. Although the standard of surgical care was high, the outcome was poor. Six patients were admitted to the ICU for a median of 5 days. One patient died, one became vegetative, and one had arm paralysis.
Major camel-related vascular injuries have a poor clinical outcome. This is related to the biomechanism of injury which combines penetrating, crushing and blunt trauma. Neck wounds of camel bites can be closed primarily after debridement.
在阿拉伯联合酋长国，大多数与动物相关的人类损伤是由骆驼造成的。这些损伤可能累及大血管，且可能危及生命。我们旨在研究与骆驼相关的人类重大血管损伤的生物力学机制、损伤部位、治疗及预后。
我们回顾性研究了2001年1月至2020年1月期间因与骆驼相关的重大血管损伤入住艾因医院的所有患者。研究变量包括人口统计学、损伤机制、损伤结构、临床表现、入院时生命体征、合并损伤、手术治疗、重症监护病房（ICU）停留时间、住院时间、并发症及预后。
共研究了7例患者；均为男性，中位年龄26岁。六例咬伤中有五例（83%）发生在骆驼发情季节。损伤严重且危及生命。骆驼咬伤会造成四个犬齿形成的小椭圆形伤口，类似于两个8厘米长的刺伤，伤口深入且损伤大血管。四例累及颈动脉，一例累及股动脉和静脉，一例累及髂外静脉，一例因从骆驼上摔落导致主动脉损伤。尽管手术治疗水平较高，但预后较差。六例患者入住ICU，中位停留时间为5天。一例患者死亡，一例成为植物人，一例出现手臂麻痹。
与骆驼相关的重大血管损伤临床预后较差。这与损伤的生物力学机制有关，该机制兼具穿透伤、挤压伤和钝挫伤。骆驼咬伤的颈部伤口在清创后可一期缝合。
