World neurosurgery, Jan 6, 2024BACKGROUND: In >70% of patients with hemifacial spasm (HFS), the offending artery is either the anterior inferior cerebellar artery (AICA) or posterior inferior cerebellar artery (PICA), without a tortuous vertebrobasilar artery (VBA). We hypothesized that anchoring perforators around the root exit zone (REZ) of the AICA or PICA might induce vascular deviation and compression. We investigated the occurrence of these perforators from the AICA or PICA and the extent of VBA tortuosity to reveal the pathology of vascular compression. METHODS: This retrospective review included 110 patients after excluding those with vertebral artery (VA) compression alone. The occurrence of perforators was determined according to operative findings within 5 mm of the REZ, and VBA tortuosity was evaluated using MATLAB. We analyzed the association between perforators, VBA tortuosity, and the surgical implications. RESULTS: The occurrence of perforators from the offending AICA or PICA around the REZ was significantly higher in the group without VA compression (Group A) than in the group with VA compression (Group B). VBA tortuosity was significantly lower in Group A. VBA tortuosity was inversely correlated with the presence of AICA or PICA perforators in all 110 patients. Operative results were similar between the groups, although patients with low VBA tortuosity tended to require interposition in decompression procedures. CONCLUSIONS: Anchoring perforators around the REZ play a crucial role in vascular compression for patients with less tortuous VBAs. Moreover, surgeons should be prepared to deal with multiple perforators in a more complicated surgery in cases of less tortuous VBA.

Neuro-Oncologyの進歩, 20(1) 17-22, Dec, 20132006年12月〜2013年2月迄の75ヵ月間に経験した鞍結節髄膜腫35例(男性8例、女性27例、24〜90歳、平均57.4歳)を対象に、手術成績と外科治療における重要なポイントについて概説した。再発症例中、視機能が既に術直前に指数弁以下でかつ術中腫瘍組織が視神経を取り囲み、視神経ならびに穿通枝に強固に癒着していた2例は部分摘出に留めた。初発例中、1例は視神経表層と視床下部への癒着腫瘍をごく僅かに残存させた。残り32例はSimpsonI、IIの全摘除であった。VISを術前後で評価できた24例では術前平均35.9から術後平均20.0にスコアが改善した。このうち2例は術直後にそれぞれ11から33、62から100に一過性に悪化したが、いずれも1年後には改善した。

Medical Torch, 9(1) 60-62, Feb, 201356歳女。右眼瞼周囲から口角の痙攣を主訴とし、CT/MRIフュージョン画像で右後下小脳動脈(PICA)と前下小脳動脈(AICA)が右顔面神経のroot exit zone(REZ)を圧迫している所見を認めた。右片側顔面痙攣と診断し、症状緩和を目的に微小血管減圧術(MVD)を施行した。術中所見でPICAがAICA meatal loopを圧迫し、圧迫されたmeatal loop末梢枝がREZを圧迫していることが判明し、MVDをベリプラストPを微量滴下セットおよびシンプルチップを用いて行った。術翌日に顔面痙攣は軽減して徐々に消失し、術後7日に独歩退院となり、現在は外来通院中である。
