【摘要】 <正> 我所神经外科自1977年5月以来,在10例颈内动脉海绵窦瘘患者中,采用电凝填塞术进行治疗,8例治愈,2例好转。此法能保持颈内动脉通畅,术后脑部血流恢复正常,是其主要优点。 手术原理和文献资料 电凝填塞术包括海绵窦直流电凝和切开填塞两种方法; 直流电凝术:此法的作用原理是:红细胞、白细胞和纤维蛋白原在正常酸碱值的血液中呈负电性。当血液中放入正、负电极时,它们移向正极;当血液中放入高电离常数的金属(如铁、铜、铍)时,它们附着于这些金属上形成血栓;当这些金属带正电时,血栓形成更更多还原

【Abstract】 Ten cases of oarotid-oavernous fistula were treated with direct operation which consisted of: (1) Five oases were treated by eleotrothrombosis according to Mullen and Hosobuohi. Four of them were cured and 1 improved. One case developed transient aphasia and hemiplegia after the operation due to cerebral arterial spasm. (2) Four oases were treated by packing the cavernous sinus with gelatin sponge. The bulging lateral wall of the sinus was incised horizontally on its antero-inferior as well as postero-superior portion. Pieces of gelatin sponge were packed into the sinus cavity, and the incisions were sutured thereafter. Among the 4 oases, 3 were cured, 1 improved. One case developed transient oculomotor palsy after surgery. (3) The remaining case was treated first with packing of the sinus but failed to obliterate the anterior portion of the fistula. A dilated pulsatile superior ophthalmic vein remained patent after the first operation. This draining vein was thrombosed with direct electric current after inserting a fine copper wire of 5 cm. in length into its lumen. The carotid-cavernous fistulae were thus occluded.The internal carotid arteries following the operations were all patent without disturbance of the normal blood circulation. The technical limitations and their risks were discussed accordingly.更多还原
