早期DSA检查对蛛网膜下腔出血的临床意义

蛛网膜下腔出血（subarachnoid hemorrhage，SAH）是临床发病率和死亡率均较高的急性脑血管病之一，并呈逐年增高趋势。随着神经介入影像学的发展，对急性SAH患早期（72h内1开展数字减影血管造影（digital subtraction angiography．DSA）检查，使SAH的早期病因诊断及病因治疗成为可能，患的预后也得到显改善。我院自2003年1月至2006年4月收治96例SAH患行早期DSA检查并给予相应的病因治疗．取得较好的临床疗效。现将有关资料与临床治疗总结报道如下。[第一段]

目的 :探讨CT引导下微创清除术治疗急性高血压脑出血的疗效。方法 :对 38例急性高血压脑出血患者微创清除术前后行CT扫描 ,在CT引导下行微创清除术 ,并动态观察其疗效。结果 :38例急性高血压脑出血患者首次血肿清除率达 2 8.0 %～ 4 0 .0 %,其中 1 2例首次清除率为 4 0 .0 %～ 5 6 .0 %。存活 32例 7d后复查头颅CT证实者血肿清除率达 80 %以上。治愈有效率为 84 .2 %,死亡率为 1 5 .8%。结论 :CT引导下的微创清除术能有效地降低急性高血压脑出血的死亡率和致残率。     

开放性眼外伤玻璃体积血的手术治疗

①目的 探讨现代玻璃体手术对开放性眼外伤玻璃体积血的治疗效果。②方法 对108例开放性眼外伤玻璃体积血的病人，于伤后2～4周施行玻璃体切割置换术(单纯玻璃体切割术24例，联合晶体切割84例，联合视网膜手术76例)。③结果 术后经随访2周～18个月，48例达功能治愈，36例达解剖治愈，总治愈率达77．7％。24例继发青光眼者眼压控制在1．37～2．24kPa。④结论 适时地施行玻璃体切割置换术，可很大程度地改善开放性眼外伤玻璃体积血病人的预后，对有效防治外伤性玻璃体视网膜病变以及牵引性视网膜脱离等具有重要作用。     

Differences in arrhythmogenicity between the canine right ventricular outflow tract and anteroinferior right ventricle in a model of Brugada syndrome

BACKGROUND: The Brugada syndrome is characterized by ST-segment elevation on the ECG, especially in the right precordial leads sensitive to the right ventricular outflow tract (RVOT). OBJECTIVES: The purpose of this study was to evaluate the hypothesis that right ventricular electrophysiologic heterogeneity caused arrhythmogenicity in the Brugada syndrome. METHODS: Action potentials (APs) were mapped on the epicardium of 14 RVOT preparations and on the transmural surfaces of 15 pairs of RVOT and right ventricular anteroinferior (RVAI) preparations isolated from canine hearts. Brugada ECG and arrhythmias were induced with pilsicainide (2.5-12.5 micromol/L), pinacidil (1.25-12.5 micromol/L), and terfenadine (2.0 micromol/L). RESULTS: Low doses of drugs elevated the J-ST segment and induced APs with both short and long action potential durations (APDs) in contiguous RVOT epicardial regions. In addition, APs in the RVOT had a larger phase 1 notch and longer APD than in RVAI. The longest APDs were in the epicardium in RVOT but in the endocardium in RVAI regions. High doses of drugs eliminated the phase 2 dome of the AP and abbreviated APDs in the epicardium but not in endocardium and reduced the epicardial heterogeneity of APs but increased the transmural gradient of APD in 14 (93%) of the RVOT preparations. In contrast, abbreviations of epicardial APDs occurred in only 4 (27%) of the RVAI preparations. Ventricular tachycardia occurred more frequently in the RVOT (47%) than in paired RVAI preparations (7%). Blocking the transient outward current reduced the heterogeneity of APs and eliminated arrhythmogenicity in all preparations. CONCLUSION: Compared with the RVAI region, the RVOT has greater electrophysiologic heterogeneity that contributes to arrhythmogenicity in this model of Brugada syndrome.     

Pediatric intracranial aneurysms—clinical characteristics and outcome of surgical treatment

Object Intracranial aneurysms are rare in children and have different epidemiological, clinical, and morphological characteristics and outcome from those in adults. Materials and methods We analyzed demographic, clinical, radiologic features, treatment, and outcome in 55 patients <18 years of age, treated from Jan 1995 through December 2005. Results Intracranial aneurysms in children below 18 years constituted 4% of all intracranial aneurysms. Internal Carotid artery (ICA) bifurcation was the commonest location. About half of the aneurysms were complex. Three-fourth of the patients required surgical treatment. Two patients died, constituting 5% mortality. Two patients (5%) had poor outcome, whereas the majority (90%) had a favorable outcome. Conclusions Pediatric aneurysms have male predominance, higher incidence of clinical features of mass effect or seizures, high incidence of large, traumatic/mycotic aneurysms, associated illnesses and ICH/IVH and hydrocephalus, better Hunt and Hess grades at presentation, ICA bifurcation as the commonest site, and better outcome than their adult counterparts.     

颅脑损伤患者上消化道出血的预防和治疗(附625例报告)

目的探讨颅脑损伤后上消化道出血的预防措施及其治疗方法。方法回顾性分析625例颅脑损伤后上消化道出血的病例,在治疗原发伤病基础上,采用止血、制酸、保护胃黏膜等对症处理,同时应用阿托品治疗22例;胃镜下治疗8例;胃次全切除术5例。结果本组病例中,治愈572例,缓解36例,无效5例,死亡12例,其中阿托品治愈20例;胃镜下治愈6例;胃次全切除术治愈4例。结论预防和治疗的重点是消除颅脑损伤病灶和保护胃黏膜,常规处理方案效果满意,简单、经济且安全有效,但必要时应及时使用特殊治疗手段,以迅速控制出血病情。
