改良大骨瓣联合软通道微创介入逐渐减压术治疗重型颅脑损伤的疗效分析

目的：探讨改良大骨瓣联合软通道微创介入逐渐减压术治疗重型颅脑损伤的疗效。方法方便选择自2009年12月—2014年11月该院收治的重型颅脑损伤病例70例,随机分为改良组和对照组2组,每组35例,改良组施行改良大骨瓣联合软通道微创介入逐渐减压术,对照组按标准大骨瓣开颅、硬脑膜一次性全切开,对比分析两组的并发症发生率及预后。结果改良组发生迟发性颅内血肿、大面积脑梗塞及弥漫性脑肿胀等并发症9例(25.7％,9/35),预后良好者23例(65.7％,23/35),对照组发生并发症19例(54.3％,19/35),预后良好者14例(40.0％,14/35),两组并发症发生率和预后差异具有统计学意义(P<0.05)。结论改良大骨瓣联合软通道微创介入逐渐减压术治疗重型颅脑损伤,效果良好,显著降低死亡率。     

小骨窗术和碎吸术治疗脑出血的临床应用研究

目的对比研究颅内血肿小骨窗清除术和颅内血肿(钻孔)碎吸清除术治疗脑出血的疗效。方法87例脑出血患者分为小骨窗组(行颅内血肿小骨窗清除术)、碎吸组(行颅内血肿碎吸清除术)和对照组(行内科保守治疗)。分别比较小骨窗组、碎吸组、保守组治疗前后的GCS评分及3组的GCS评分差。采用t检验、χ2检验和单因素方差分析比较。结果小骨窗组、碎吸组与保守组的GCS评分差比较均有差异(P<0.05);小骨窗组和碎吸组的GCS评分差比较也有差异(P<0.05)。结论小骨窗颅内血肿清除术、碎吸颅内血肿清除术、内科保守疗法在脑出血治疗中均能发挥一定的作用。小骨窗术和碎吸术在治疗中均能提高疗效、加快神经功能恢复,但小骨窗术较碎吸术能更好地发挥疗效、提高病人的生存质量。

Remote subarachnoid haemorrhage in the posterior fossa following supratentorial surgery

Summary Haemorrhage in regions remote from the site of following intracranial operations is rare, but they do occur. We performed supratentorial craniotomy on 639 patients between the time of introduction of computed tomography (CT) for clinical use in 1983 and June 1992; subarachnoid haemorrhage (SAH) in the posterior fossa occurred postoperatively in six of these cases. These included four patients with tumours in the sellar region, one with an arteriovenous malformation (AVM) and one who underwent superficial temporal artery (STA)-middle cerebral artery (MCA) anastomosis. The ages of the six patients ranged from 17–72 years.Haemorrhage occurred on the day of operation in one case and was detected on CT examination on the day following surgery in the remaining five cases. Of three patients with disturbance of consciousness, two underwent suboccipital craniectomy for reduction of intracranial pressure, while one received barbiturate therapy and later underwent cerebrospinal fluid (CSF) shunt surgery. No special treatment was necessary for the remaining three patients with less serious lesions. Five of the six patients ultimately recovered their pre-operative neurological status apart from the primary diseases.Factors inducing such haemorrhages seem likely to include displacement of the cerebellum by reduced CSF pressure during and after operations, and stretching and tearing of the veins and venules in the sulci of the tentorial surface of the cerebellum. Consideration should therefore be given to the maintenance of an appropriate CSF pressure during operation; this is particularly important in elderly patients and those with an atrophied cerebral cortex.     

Anaesthetic management during awake craniotomy in a 12-year-old boy

We present our approach to the preoperative preparation and anaesthetic management for awake craniotomy in a 12-year-old boy. Management included conscious sedation with a propofol infusion plus local anaesthetic infiltration of the scalp, periosteum, and dura. The complications which may be encountered during such procedures and their treatments are reviewed.     

Results of surgical treatment in patients with arachnoid cysts

Summary A retrospective study of 35 patients operated upon for arachnoid cysts during the last 10 years was carried out. In 19 patients treated by craniotomy, membrane resection and drainage into the basal cisterns, clinical improvement could be noted in 13 cases. Correspondingly on the CT-controls the cysts were found to have disappeared in two cases and were reduced in size in seven patients.In 11 patients, however, who were initially treated by a shunting procedure, seven patients became free of symptoms. Postoperative CT-controls showed in three cases a significant reduction of the size of the cyst, which remained unchanged in two other cases.In five patients with the combination of a nonspace-occupying arachnoid cyst and subdural effusions, drainage of the latter only was sufficient to relieve the clinical symptoms.The prominent Endings were the high complication rate of the primary or secondary shunting procedures (48%), as well as the close correlation between the clinical outcome and the postoperative CT-controls.     

去骨瓣减压术治疗大面积脑梗死的短期疗效评价

目的:评价去骨瓣减压术治疗大面积脑梗死的效果。方法:制定入选和排除标准,统一术式,比较术前、术后不同时期的神经功能变化,并对存活病例进行随访(6个月),评价术后3和6个月时的预后评分(GOS)和BarthelIndex(BI)的变化。结果:按入选标准行去骨瓣减压术26例,术后死亡率为30.8%。术前昏迷评分GCS对决定手术时机有指导作用。共随访14例患者,术后3和6个月GOS分别为3.6±0.8和4.0±0.8,与出院时GOS评分比差异有统计学意义。术后3和6个月BI分别为68.9±29.4和77.5±28.3,其中术后6个月BI>60者占85.7%。结论:对保守治疗无效的大面积脑梗死患者,去骨瓣减压术不仅可作为一种“救命”手术,而且多数存活病例恢复较好。合理选择手术适应证、及时把握手术时机以及充分手术减压可能是影响预后的重要因素。

开颅术后张力性气颅

报告１９８８年１２月～１９９２年１２月开颅术后张力性气颅５例，男４，女１．５例中３例治愈，２例死亡。开颅术后张力性气颅产生的主要原因是颅内占位性病变切除后，脑脊液丢失，使颅内压降低，甚至呈负压状态，外界的气体从切口进入颅内的腔隙，ＣＴ扫描或颅骨Ｘ线平片可以确定诊断，钻孔置管排气是活疗张力性气颅的有效方法，作者探讨了预防此种并发症发生的措施。
