【摘要】 目的 研究改良Paine點側腦室額角穿刺的解剖基礎及臨床應用。 方法 利用MRI模型的構建,模擬改良Paine點穿刺側腦室額角。測量穿刺距離、角度及其對Broca語言功能區和尾狀核的影響。改良Paine點(Pm點)比Paine點高1 cm,更加遠離Broca語言功能區,穿刺時需要與軸面夾角20°向下,可以越過尾狀核頭從側腦室額角上壁進入腦室;與矢狀面夾角約70°向下、冠狀面夾角約20°向后穿刺。從皮層計算進針4.0~5.5 cm可進入側腦室額角。 結果 同期7例顱內動脈瘤患者術中應用Pm點穿刺成功,術后無語言功能障礙,復查頭顱CT無穿刺道及尾狀核頭出血現象。 結論 Pm點法定位方法簡便準確,能避免Broca語言功能區和尾狀核頭部的損傷,有一定臨床應用推廣價值。
【Abstract】 Objective To analyze the anatomic characteristics and clinical application of modified Paine entry point (Pm) for lateral ventricular puncture through pterional approach. Methods We simulated the modified Paine entry point for lateral ventricular frontal horn puncture by reconstructing the model of MRI. Distance and angles of the puncture path were measured to evaluate the influence upon the language areas of Broca and the head of the caudate nucleus. The Pm point is 1 cm higher than the Paine point, so it is more far away from the Broca area. The direction of the puncture path should be 20° downward with the axial plane, 70° downward with the sagittal plane and 20° backward with the coronal plane. The catheter was inserted into the ventricle 4.0 to 5.5 cm deep to the cortex. Results Seven patients with intracranial aneurysms underwent ventricular puncture successfully through the Pm point in operation. None of them suffered language dysfunction or hemorrhage lesions in the caudate nucleus by the computed tomography. Conclusion The modified Paine entry point can be located accurately and has the clinical value for preventing damage of the Broca area and the caudate nucleus.
