文献概要
要旨:精索静脈瘤は主に内精索静脈経由の逆流で生じ,ときに外精索静脈,精管静脈,外陰部静脈,精巣導帯静脈からの逆流で生じる。精索静脈瘤は不妊症,精巣発育障害や陰囊症状の原因となり,治療の原則は主な逆流経路である内精索静脈を結紮・切断し,逆流を遮断することである。主な術式に顕微鏡下低位結紮術,高位結紮術,腹腔鏡下手術があり,①手術侵襲や術後の疼痛・回復期間,②静脈瘤の再発率,③精巣水瘤の発生頻度,④手術の難易度,⑤腹腔鏡下手術や顕微鏡下手術の経験,⑥動脈温存の必要性とそれに伴う難易度の上昇,⑦内精索静脈以外の静脈処理の必要性などを考慮し,術式を選択することが重要である。今回,主に顕微鏡下低位結紮術および高位結紮術について述べる。
