 note = {【目的】海綿静脈洞部硬膜動静脈瘻（CSdAVF）に対するdouble micocatheter technique（DMT）による経静脈的塞栓術（TVE）の有用性について検討した．【対象と方法】CSdAVF 11例（男：女　１：10, 年齢56～81歳　平均66.9歳）に対して13回のTVEを行った．２本のマイクロカテーテルをCS内に留置後，それぞれのカテーテルを逆流静脈（RLVD）および上眼静脈（SOV）へ誘導し，RLVD，SOV，CSの順で塞栓した．【結果】13回のTVEのうち，11回（85%）で２本のマイクロカテーテルをCS内に誘導できた．すべてのRLVDにマイクロカテーテルを選択的に誘導でき，塞栓術中に新たに生じたRLVDに対しても，１本のマイクロカテーテルを移動させることですみやかに塞栓を行った．初回治療後の解剖学的および臨床的治癒率は，ともに82%であった．【結語】CSdAVFに対してDMTによるTVEを行った．RLVDへの選択的なマイクロカテーテルの誘導は困難ではなく，また術中の静脈流出路変化にも容易に対応できた．解剖学的および臨床的予後も良好であり，CSdAVFのTVEの有用な方法である． Objective: We describe a double microcatheter technique for transvenous embolization (TVE) of cavernous sinus dural arterio-venous fistulas (CSdAVFs). Method: Eleven patients with CSdAVF were treated by TVE. We tried to navigate two microcatheters through the inferior petrosal sinus to the cavernous sinus (CS) and catheterized to the veins which had shown retrograde leptomeningeal venous drainage (RLVD), and the superior ophthalmic vein (SOV). We evaluated success rate of navigation of double microcatheters to the CS, success rate of superselective catheterization to the RLVD and the SOV, and angiographical and clinical cure rates. Result: We performed 13 sessions of TVE for 11 patients. Two microcatheters were successfully navigated to the CS in 11 of 13 sessions (85%). The microcatheters were successfully catheterized to all of the RLVD and the SOV superselectively. In one case, we were able to transfer one of the two microcatheters to the new RLVD, which appeared during embolization of pre-existing RLVD, and were able to occlude dangerous drainage immediately. Both angiographical and clinical cure rates at the initial treatment were 82%, and final angiographic and clinical cure rates were 100%. Conclusion: A double microcatheter technique for TVE of CSdAVF is a safe and useful procedure with good angiographical and clinical outcomes.},
