Hypothenar hammer syndrome is an uncommon cause of symptomatic ischemia of the hand secondary to the formation of aneurysm or thrombosis of the ulnar artery as a result of repetitive trauma to the hypothenar region. The injury to the palmar ulnar artery occurs in subjects who use the hypothenar part of the hand as a hammer; the hook of the hamate strikes the superficial palmar branch of the ulnar artery in the Guyon space. Such injuries of the ulnar artery may lead to severe vascular insufficiency in the hand with thrombosis and distal embolization of the digital arteries. Imaging of vascular lesions of the hand has greatly improved in recent years with the use of Doppler, multislice computed tomographic angiography, magnetic resonance imaging, magnetic resonance angiography, and digital subtraction angiography. The aim of this article is to describe a case report using current-day imaging and to present a review of literature. Algorithms for the diagnosis and treatment of hypothenar hammer syndrome will be proposed.
小鱼际锤状指综合征是手部症状性缺血的一种罕见病因，继发于小鱼际区域反复创伤导致尺动脉形成动脉瘤或血栓。手掌尺动脉损伤发生在将手部小鱼际部分用作锤子的人群中；钩骨钩撞击Guyon管内尺动脉的掌浅支。这种尺动脉损伤可能导致手部严重的血管功能不全，伴有指动脉血栓形成和远端栓塞。近年来，随着多普勒、多层计算机断层血管造影、磁共振成像、磁共振血管造影和数字减影血管造影等技术的应用，手部血管病变的影像学检查有了很大改善。本文旨在描述一例使用当今影像学检查的病例报告，并对文献进行综述。将提出小鱼际锤状指综合征的诊断和治疗算法。
