A 43-year-old male was admitted for subcutaneous mass of rt. inguinal lesion. Saccular dilatation of vein is a rare phenomenon and usually termed "venous aneurysm". Venous aneurysm has been reported in the following vein: face, neck, extremities, superior vena cava region, portal vein region and by-pass grafting vein. This is the 1st report of a venous aneurysm found in V. saphena accessories in Japan. The true etiology is unknown, but underlying causes which produce damage to the venous wall (trauma, inflammation, congenital weakness, and localized degenerative change) have been mentioned as possible causes. Rarely, thrombosed venous aneurysm may cause pulmonary emboli. Definitive diagnosis is established by venography. Venous aneurysm often increases or reduces in size according to the change of venous pressure by proximal vein compression postural change and Valsalva maneuver. In general, surgical resection of the aneurysm is the treatment of choice.
一名43岁男性因右腹股沟区皮下肿物入院。静脉囊状扩张是一种罕见现象，通常称为“静脉瘤”。静脉瘤已在以下静脉中被报道：面部、颈部、四肢、上腔静脉区域、门静脉区域以及旁路移植静脉。这是日本首次报道在副隐静脉中发现静脉瘤。真正的病因尚不清楚，但已提及对静脉壁造成损伤的潜在原因（创伤、炎症、先天性薄弱和局部退行性改变）可能是病因。罕见情况下，血栓形成的静脉瘤可能导致肺栓塞。通过静脉造影可明确诊断。静脉瘤的大小常根据近端静脉受压、体位改变和瓦尔萨尔瓦动作引起的静脉压力变化而增大或减小。一般来说，手术切除动脉瘤是首选的治疗方法。
