  <p><b>Introduction: </b>We conducted an investigation on cerebrospinal fluid leakage after planned dural incision in our department and compared the results.</p><p><b>Subjects and Methods: </b>The study included 75 cases (37 males, 38 females) with a mean age of 56.2 years and a mean follow-up period of 37.1 months. We examined the disease, laminectomy method (bilateral or unilateral), dural treatment method, and postoperative MRI.</p><p><b>Results: </b>The diseases comprised 72 cases of spinal cord tumors and 3 other spinal conditions. Laminectomy methods consisted of bilateral in 46 cases and unilateral in 29 cases. Dural treatment methods included suturing in 54 cases and the Vascular Closure System clips (VCS) in 21 cases. Cerebrospinal fluid leakage was observed in 20 cases (26.6%) overall on the first MRI at an average of 3 months postoperatively. With regard to laminectomy, no significant differences were found between bilateral (34.7%) and unilateral (13.7%) cases (NS). For dural treatment, suturing was observed in 29.6% and VCS in 19.0% (NS). In particular, leakage was significantly less (6.2%) in cases of unilateral laminectomy using VCS compared to three cases of bilateral laminectomy with VCS (60%) (P=0.03).</p><p><b>Conclusions: </b>Reducing dead space is crucial in the prevention of cerebrospinal fluid leakage. The combination of the less invasive unilateral laminectomy and VCS could help reduce postoperative cerebrospinal fluid leakage compared to bilateral laminectomy.</p>

  症例は69歳男性で、9ヵ月前から左後頭部に蟻走感を自覚しており、2ヵ月前から疼痛をきたして受診となった。神経学的所見では上下肢に筋力低下はみられなかったが、右二頭筋反射と両側膝蓋腱反射の亢進を認め、頸椎ダイナミックX線検査では環椎歯突起間距離は屈曲位で2.2mm、伸展位で1.2mmを示していた。C1/2関節に不安定性はみられず、MRIではT1強調像にて等信号、T2強調像にて低信号を示す歯突起後方偽腫瘍が検出され、左臓側に伸展して左C2神経根の圧迫所見が観察された。疼痛に対してセレコキシブとプレガバリンを処方し、C2神経根ブロックを施行した。神経根ブロック後には一時的に疼痛緩和が得られたものの、その後に再発を呈したため、外科的治療を行う方針とした。環椎後弓に対する椎弓切除を行ったところ、偽腫瘍は左C2神経根分岐部と脊髄との間に位置しており、左C2神経根は偽腫瘍によって圧迫されていた。偽腫瘍に対する部分切除で神経根の減圧が得られ、組織病理所見では偽腫瘍内に軟骨様組織が認められた。術後のMRIでは偽腫瘍の再増殖は認められず、術後9ヵ月、症状の再発は認めていない。
