颅内破裂动脉瘤手术时机的探讨(附237例分析)

目的探讨颅内破裂动脉瘤手术时机与临床预后的关系。方法回顾性分析2005年我院收治的237例颅内破裂动脉瘤，其中196例行手术治疗。按入院时Hunt—Hess分级将手术病人分为A组（Ⅰ～Ⅲ级）162例，B组（Ⅳ、Ⅴ级）34例；根据手术时间分为早期手术组（SAH3d内手术）19例，延期手术组（SAH4～10d手术）82例，晚期手术组（SAH11d之后手术）95例。比较不同手术期别动脉瘤术中破裂率、术后1个月GOS评分及术后主要并发症（脑血管痉挛、脑积水）发生率，并进行统计学分析。结果24例（10．1％）因再出血丧失治疗机会。术中动脉瘤破裂早期手术组3例（15，8％），延期手术组8例（9．8％），晚期手术组6例（613％）。术后脑血管痉挛发生率早期手术组为15，8％，延期手术组为19，5％，晚期手术组为17，9％。脑积水发生率以晚期手术组最高（14，7％）。对术后1个月GOS评分Ridit分析结果显示：A、B两组中均以早期手术组治疗效果最佳．延期手术次之．晚期手术最差。结论早期手术可规避颅内破裂动脉瘤再出血的风险，降低主要并发症发生率。对于各个级别（包括Ⅳ、Ⅴ级）的SAH病人，均应根据治疗者的手术经验与技巧和所在医院的条件，及早诊断，尽早手术。     

Percutaneous Transhepatic Cholangiodrainage as Rescue Therapy for Symptomatic Biliary Leakage Without Biliary Tract Dilation After Major Surgery

Symptomatic biliary leakage following major upper abdominal surgery is a severe complication resulting in increased morbidity and mortality. Treatment options usually include either endoscopic intervention or surgical revision. These options may be burdened by a high perioperative risk for the patient (e.g., patients with severe disease) or simply may not be possible (e.g., nonpreserved gastroduodenal passage). In the past, percutaneous transhepatic cholangiodrainage did only seem to be a viable option for patients with dilated bile ducts. Here, we present our experience in a consecutive series of patients with symptomatic biliary leakage following major upper abdominal surgery and without dilation of the biliary system that underwent percutaneous transhepatic cholangiodrainage. Percutaneous transhepatic cholangiodrainage was feasible in 15 of 18 patients (83.3%). The procedure was technically not possible in three patients (16.7%). In 10 of the 15 patients (66.6%) with feasible percutaneous transhepatic cholangiodrainage, biliary leakage was definitely controlled without the need for surgical revision. Depending on the experience with the interventional procedure, percutaneous transhepatic cholangiodrainage should be considered as an alternative for treatment of symptomatic biliary leakage instead of immediate reoperation.

Use of laboratory data to identify risk factors of giant coronary aneurysms due to Kawasaki disease

BACKGROUND: Although some laboratory findings are known to be indicators of the risk of giant coronary aneurysm formation among Kawasaki disease patients, an appropriate cut-off point to predict aneurysm formation is not clear. METHODS: One hundred and five patients with giant coronary aneurysms were selected from the 15th and 16th nationwide surveys of Kawasaki disease in Japan. A total of 2936 patients without Kawasaki disease were recruited from a single hospital as a control group. Odds ratios were calculated for six laboratory data with specific values as cut-off points. Receiver operating characteristic (ROC) curves were observed to determine the most appropriate laboratory tests and cut-off points. RESULTS: Hematocrit, leukocyte count, neutrophil proportion, and hemoglobin had one or more peaks of odds ratio for specific cut-off points, but they did not have a clear cut-off point for the predictor according to the receiver operating characteristic curves. Alanine aminotransferase (ALT) increased the risk of giant coronary aneurysms continuously so no clearly appropriate cut-off point was identified. Serum sodium concentration of 135 mEq/L had a peak of odds ratio, and those with <135 mEq/L had the highest odds ratio (4.78). This value seemed appropriate with a sensitivity of 78% and specificity of 57%, although the predictive positive value was as small as 5%. CONCLUSION: The author's propose that a serum sodium concentration of <135 mEq/L at the patient's first visit to hospital may be a predictor of giant coronary aneurysms due to Kawasaki disease.     

造影剂到达腹主动脉的峰值大小与患者因素的关系

目的探讨造影剂到达腹主动脉的峰值大小与患者因素之间的关系。方法108例患者以2.5ml/s注射欧乃派克(300mgI/ml)20ml,12s后采用testbolus技术在腹腔干水平同层动态扫描腹主动脉,用dynamic evaluation软件测得腹主动脉的峰值大小,采用单因素回归分析和多因素逐步回归分析法研究患者的性别、年龄、身高、体重、心率、血压、注射位点、达峰时间及是否有心脏病、糖尿病、或化疗史对造影剂到达腹主动脉峰值大小是否有影响及影响程度。结果造影剂到达腹主动脉峰值大小,在男性平均比女性低;其随年龄、身高、体重、达峰时间的增加而逐渐降低,注射位点在手背静脉其值平均比在肘部静脉低;其不受心率、血压、是否有心脏病、糖尿病或化疗史的影响。参考公式:峰值大小(HU)=383.8400-身高(cm)×1.0909-体重(kg)×0.6760 注射位点×16.7878-达峰时间(s)×1.6882。结论可根据患者的性别、年龄、身高、体重、注射位点和达峰时间来适当调整患者CT血管成像时造影剂用量。

Saccular Aneurysm of the Azygos Anterior Cerebral Artery: Three Case Reports

The azygos anterior cerebral artery, a rare anomaly in the circle of Willis in which only a single vessel supplies the medial aspects of both anterior cerebral hemispheres, is closely associated with saccular aneurysms. We present three cases of azygos anterior cerebral artery aneurysms among the 781 cerebral aneurysms surgically treated at our institution in an 11-year period. These three cases all involved elderly women who presented with subarachnoid hemorrhage. Conventional cerebral angiography and CT angiography revealed small saccular aneurysms at the distal ends of the azygos anterior cerebral arteries. These aneurysms were clipped successfully using a bifrontal interhemispheric approach. Hence, the pathogenesis of these particular aneurysms relating to hemodynamic change, associated anomalies, and surgical pitfalls is discussed with review of literature.     

应用新型球囊Hyperglide或Hyperform辅助弹簧圈技术栓塞治疗颅内宽颈动脉瘤(附22例分析)

目的探讨采用新型MTI球囊重塑技术栓塞治疗颅内宽颈动脉瘤的可行性及有效性。方法总结22例26个宽颈动脉瘤的栓塞治疗经验。均采用新型球囊Hyperglide或Hyperform置于载瘤动脉处,同时将微导管置于动脉瘤内,充盈球囊以封闭瘤颈口后将合适的弹簧圈推送进入动脉瘤内,重复进行充盈球囊和填塞过程,直至动脉瘤致密填塞。结果19例23个动脉瘤成功填塞;1例前交通动脉瘤因血管迂曲致球囊不能到位而改用其他技术栓塞;另1例前交通动脉瘤因球囊选择不当,瘤颈封堵不完全,导致部分弹簧圈移位进入载瘤动脉;1例动脉瘤术中破裂出血,病人死亡。结论新型球囊重塑技术有助于达到宽颈动脉瘤致密、有效的栓塞。
