要旨 経皮的心膜生検を3例(癌性心膜炎2例,特発性1例)に対して施行した.剣状突起下より心嚢穿刺した後,セルジンガー針の外筒からガイドワイヤーを心嚢腔内に透視下で入れ,シースを挿入した.心筋生検用鉗子を挿入し壁側心膜より検体を採取した.合併症は認めなかった.経皮的心膜生検は低侵襲で簡便に行え安全性も高く,心嚢水細胞診に比べ組織診断が可能であり,診断と治療方針決定に有用な検査法になり得ると考えられた.
We have performed percutaneous pericardial biopsiesfrom three patients (two with malignant pericarditisand one idiopathic). Pericardiocentesis was performedthrough the subxiphoid approach. Through the needlesheath, a guidewire was inserted into the pericardialspace and the sheath was inserted over the guidewire. Amyocardial bioptome was introduced into the pericardial cavity. and pericardial biopsies were performed.There were no complications. Percutaneous pericardialbiopsies can be performed less invasively, easily andsafely, and be of great value in the histological diagnosisand treatment of pericardial effusion.
