BACKGROUND: Evolution of keyhole techniques in aneurysm surgery allows for definitive surgical management of aneurysmal pathology with little disruption of normal surrounding tissue. While experienced vascular neurosurgeons are increasingly applying keyhole techniques to unruptured aneurysms, experience with ruptured aneurysms is limited. OBJECTIVE: We sought to explore technical nuances and present operative outcomes for our series of 40 consecutive patients presenting with ruptured intracerebral aneurysms treated with surgical clipping via a keyhole approach. METHODS: This study is a consecutive, single-surgeon, single-center retrospective case series of aneurysms clipped with keyhole approaches at Helen Joseph Hospital in Johannesburg, South Africa. Patients presenting with subarachnoid hemorrhage were worked up exclusively with computed tomography. On the basis of vessel location and unique anatomic features, aneurysms were clipped through one of these approaches: minipterional, supraorbital, or keyhole interhemispheric. Operative details were assessed on retrospective file review, and patient outcomes were assessed on clinic follow-up. RESULTS: A minipterional approach was used for 55% of cases, the supraorbital approach in 30% of cases, and the mini-interhemispheric approach in 15% of cases. The intraoperative aneurysm rupture rate was 26.2%. Complete aneurysm occlusion was achieved in 97.4% with none of the 40 cases requiring conversion of a keyhole to a larger craniotomy. A good outcome was achieved for 72.5% of patients (modified Rankin Scale score ≤2). For patients presenting with World Federation of Neurological Surgeons grade I to III subarachnoid hemorrhage, 92.9% achieved a good outcome. CONCLUSIONS: The present series supports the concept that sound technical execution of keyhole approaches, even in the setting of acutely ruptured cerebral aneurysms, is a viable option for clipping of intracranial aneurysms.
背景:锁孔技术在动脉瘤手术中的发展使得能够在不破坏正常周围组织的情况下对动脉瘤病变进行明确的手术治疗。虽然经验丰富的血管神经外科医生越来越多地将锁孔技术应用于未破裂的动脉瘤,但对破裂动脉瘤的经验有限。
目的:我们旨在探讨我们连续 40 例破裂性颅内动脉瘤患者通过锁孔入路手术夹闭的技术细节和手术结果。
方法:本研究是南非约翰内斯堡海伦约瑟夫医院的一项连续的、单外科医生、单中心回顾性病例系列研究,对蛛网膜下腔出血患者进行计算机断层扫描检查。根据血管位置和独特的解剖特征,通过以下方法之一夹闭动脉瘤:翼点入路、眶上入路或锁孔侧裂入路。通过回顾性文件审查评估手术细节,通过临床随访评估患者结局。
结果:55%的病例采用翼点入路,30%的病例采用眶上入路,15%的病例采用迷你侧裂入路。术中动脉瘤破裂率为 26.2%。97.4%的病例完全闭塞动脉瘤,无 40 例病例需要将锁孔转换为更大的开颅术。72.5%的患者(改良 Rankin 量表评分≤2)获得良好结局。对于 WFNS 分级 I 至 III 级蛛网膜下腔出血的患者,92.9%获得良好结局。
结论:本系列支持这样的观点,即在急性破裂性脑动脉瘤的情况下,即使采用锁孔技术,只要技术执行得当,也是颅内动脉瘤夹闭的可行选择。
