Evacuation of hematomas using liposuction technology: Technique and literature review

Established nonexpanding hematomas can be successfully treated with minimal morbidity using standard liposucstion techniques at the bedside or in an outpatient setting under local anesthesia. The authors presents a series of eight patients and discuss current concepts of dealing with this common and distressing surgical complication.     

头部外伤诱发颅内肿瘤卒中

目的 通过复习文献，对颅内肿瘤引起的颅内出血发生机制和临床特点进行探讨，旨在引起临床医师们的重视，以减少误诊误治。方法 本文报告9例误诊为外伤性颅内血肿的瘤卒中患者，其中5例术中发现颅内肿瘤同时切除，3例术后复查CT发现颅内肿瘤，二次手术切除。结果 全部病例随访6月，4例死亡，5例存活。结论 对疑为瘤卒中的颅内血肿患者，除仔细询问病史，全面体查外，术中应仔细寻找出血源，观察周围脑组织的改变，对可疑病变组织、血块及其腔壁一并切除，分送病检，从而作出正确的治疗方案。

Computed tomography features immediately after replacement of haematoma with oxygen through percutaneous subdural tapping for the treatment of chronic subdural haematoma in adults

Summary In an effort to achieve a simple and less invasive method for the treatment of chronic subdural haematoma, replacement of the haematoma with oxygen by percutaneous subdural tapping was employed in 36 patients. This study was conducted on 23 haematomas in 20 patients, whose computed tomography (CT) scans immediately following the treatment were available for evaluation, with particular regard to distinguishing between their findings and those seen with tension pneumocephalus. The CT features werde divided into two patterns according to the location of oxygen; a convexity type (19 haematomas) and an interhemispheric type (4 haematomas). Analysis of the CT appearances revealed the oxygen was exclusively confined to the haematoma cavity, distinguishing it from the findings in tension pneumocephalus. This observation indicates the safety of replacement of the haematoma with oxygen when combined with our percutaneuous subdural tapping technique which prevents lesions of the inner haematoma membrane.     

Bilateral organized chronic subdural haematomas: High field magnetic resonance images and histological considerations

Summary The authors describe a 66-year-old man with progressive gait disturbance caused by bilateral organized chronic subdural haematomas. The characteristics of these lesions on magnetic resonance (MR) images have not yet been clarified. The organized haematoma in our patient exhibited slight hypo-intensity on T 1-weighted MR images and marked hypo-intensity on T 2-weighted MR images obtained at 1.5 T. Preoperative MR imaging may give us useful information about surgical strategy in the case of chronic subdural haematoma with an unusual appearance on computed tomographic (CT) scans.     

影响急性外份性硬脑膜外血肿疗效的相关因素分析（附484例报告）

目的探讨影响急性外伤性硬脑膜外血肿疗效的相关因素。方法对1994年5月至2004年5月收治的484例外伤性硬脑膜外血肿患者的临床资料进行回顾性分析。结果无脑疝症状者手术死亡率7.7%,有脑疝症状者死亡率21.3%。手术距脑疝发生时间<1h死亡率8.2%,1～2h死亡率40.0%,>2h死亡率72.2%。结论影响外伤性硬脑膜外血肿疗效的相关因素较多,除脑疝形成及手术距脑疝发生的时间外,创伤性低血压、合并脑损伤的程度、呼吸功能不全、大面积脑梗塞、血糖与血浆渗透压升高及肝功能异常等均对患者预后有重要影响。     

简易定向锥颅脑内血肿碎吸术治疗高血压脑出血——介绍一种简易脑内血肿碎吸器的研制及临床应用

本文介绍一种高血压脑出血外科治疗的新方法,即简易定向锥颅脑内血肿碎吸术。截至1988年10月临床应用19例,年龄41～79岁,出血量平均为48.1ml,一次吸除量为总量的79％(38ml),术后立即清醒者8/19例,偏瘫好转者4/19例,死亡4例。实践证明本法简单,安全有效,病人负担轻。     

Acute subdural hematoma: Outcome and outcome prediction

Patients with traumatic acute subdural hematoma were studied to determine the factors influencing outcome.Between January 1986 and August 1995, we collected 113 patients who underwent craniotomy for traumatic acute subdural hematoma. The relationship between initial clinical signs and the outcome 3 months after admission was studied retrospectively.Functional recovery was achieved in 38% of patients and the mortality was 60%. 91% of patients with a high Glasgow Coma Scale (GCS) score (9–15) and 23% of patients with a low GCS score (3–8) achieved functional recovery. All of 14 patients with a GCS score of 3 died. The mortality of patients with GCS scores of 4 and 5 was 95% to 75%, respectively. Patients over 61 years old had a mortality of 73% compared to 64% mortality for those aged 21–40 years. 97% of patients with bilateral unreactive pupil and 81% of patients with unilateral unreactive pupil died. The mortality rates of associated intracranial lesions were 91% in intracerebral hematoma, 87% in subarachnoid hemorrhage, 75% in contusion.Time from injury to surgical evacuation and type of surgical intervention did not affect mortality. Age and associated intracranial lesions were related to outcome. Severity of injury and pupillary response were the most important factors for predicting outcome.     

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.
