Summary In 50 rats, different types of end-to-side carotid artery anastomoses were compared. In one technique, a longitudinal split in the long axis of the vessel was performed to enhance the diameter of the anastomosis. This theoretical advantage was not confirmed in this series. The clamping time, anastomoses time, and tamponade time were increased significantly when compared with a simple, slightly oblique end-to-side anastomosis. This study highlighted that the most simple type of end-to-side anastomosis gave less bleeding, achieved a quicker water-tight anastomosis and decreased the risk of late problems. 相似文献

Pulmonary aspergillosis associated with old tuberculosis is generally resistant to treatment. Thus, if patients are treated
only with conservative therapy, their condition continues to deteriorate due to repetitive hemoptysis, and may even become
critical. Surgical treatment is required for these patients; however, it is extremely difficult to resect the lesion due to
severe adhesions to the chest wall and vascular proliferation surrounding the lesion. We performed preoperative arterial embolization,
achieving good results in three patients with hemoptysis caused by pulmonary aspergillosis. The feeding arteries were embolized
using microcoils and/or gelatin sponges, and a lobectomy was safely carried out in all patients. We concluded that preoperative
arterial embolization is a safe and effective technique to prevent massive hemorrhage occurring at the time of surgery.

Summary The sensitivity of the cochlea is dependent upon maintenance of a delicate homeostatic environment. One mechanism which participates in providing this environment is the autoregulation of cochlear blood flow. This autoregulation is ensured through the interaction of sympathetic, peptidergic and hemodynamic mechanisms. The current study demonstrates an adaptation that also participates in cochlear blood flow autoregulation. Specifically, an anterior inferior cerebellar arterial network is described and the relative contributions of each of its vessels to total cochlear blood flow is measured using laser Doppler flowmetry. The results show that each collateral vessel contributes to the blood supply of the cochlea and that reperfusion is accompanied by hyperemia. These findings suggest an adaptation that provides stable blood flow through redundancy and compensatory potential. Additionally, these observations have implications for experimental models of ischemia. 相似文献

阿霉素磁性明胶微球的研究 总被引:2,自引:0,他引:2
报告了阿霉素磁性明胶微球(Adr-MG-ms)的制备与性质,研究了超细氧化铁粒子的合成和磁性明胶微球(MG-ms)在狗体内的栓塞效果。阿霉素磁性明胶微球由2%阿霉素(Adr)、68%明胶和30%的磁铁粒子组成,微球的平均粒径为22μm。在体外实验中,药物释放速度证明微球有缓释的性质。磁铁粒子的平均粒径约为10nm,磁性明胶微球与 ̄(99m)Tc标记磁性明胶微球通过导管分别输入狗的肝动脉内进行栓塞,照相和血管造影显示在未加外磁场时磁性明胶微球在左右肝叶分布几乎相等,而在1200高斯的外磁场作用下,靶部位肝左叶的微球分布是肝右叶的2.25倍,而甲状腺、脑、心脏的微球很微量,结果表明磁性明胶微球在外磁场作用下是一个很好的治疗肝癌的栓塞剂。 相似文献

Summary Transcatheter inferior phrenic arterial (IPA) and hepatic arteriography was performed on 38 patients with advanced primary
hepatic carcinoma (PHC) with blood supplied by IPA and hepatic artery. 18 patients received single treatment with hepatic
arterial infusion (HAI) or embolization (HAE) 20 received double treatment with IPA and hepatic arterial infusion or embolization.
The results show that the double treatment is superior to the single one. The angiographic features and mechanism of parasitization
of inferior phrenic arterial supply to PHC were also discussed. 相似文献

Objective: To observe the oxidative modification of high density lipoprotein (HDL) induced by culturedhuman arterial smooth muscle cells (SMCs). Methods: HDL cocultured with SMCs at 37℃ in 48 h was subjected,and native HDL (N-HDL) served as control. Oxidative modification of HDL was identified by using agarose gel electro-phoresis. Absorbances of conjugated diene (CD) and lipid hydroperoxide (LOOH) were measured with ultravioletspectrophotometry at 234 and 560 nm respectively, and fluorescence intensity of thiobarbuturic acid reaction substance 相似文献

脾动脉栓塞治疗外伤性脾破裂28例临床疗效观察 总被引:3,自引:0,他引:3
目的:探讨脾动脉栓塞术对外伤性脾破裂的疗效及并发症的处理。方法:采用Seldinger法行脾动脉栓塞术治疗外伤性脾破裂28例。结果:所有患者出血立即停止,其中4例行2次栓塞。28例均有脾区疼痛,22例发热。脾动脉栓塞5天后血小板、白细胞上升近1倍,7天后恢复至正常范围。28例随访6-36月,查免疫球蛋白、CT等结果满意,未有再出血及发生暴发性感染。结论:脾动脉栓塞不但有良好的止血作用,而且能保留脾脏的免疫功能,可在非手术治疗失败时选用,是外伤性脾破裂的一种有效治疗方法。 相似文献

采用动脉血氧饱和度仪对52例新生儿肺炎患儿,在雾化吸入治疗过程中的动脉血氧饱和度(SaO2)进行了监测,对比了吸氧与否对SaO2改变的影响。结查表明:与基础值比较,雾化吸入时患儿的SaO2显著下降(P<0.01),而雾化吸入同时吸氧者SaO2无明显变化(P>0.05),但两者比较具有显著性差异(P<0.01)。结果提示雾化吸入可使新生儿肺炎患儿SaO2下降;同时吸氧,对防止SaO2的下降有一定作用。 相似文献
