目的 探讨腹主动脉预置球囊阻断术在凶险性前置胎盘患者剖宫产中的应用价值.方法 选取我院2015年9月～2019年9月收治的57例凶险性前置胎盘患者作为研究对象,行腹主动脉预置球囊阻断术的患者为研究组(n=22),未行腹主动脉预置球囊阻断术的患者为对照组(n=35).比较两组患者的术中出血量、术中输血量、手术时间、住院时间、转重症监护室率、子宫切除率及术后并发症的发生率.结果 研究组术中出血量、术中输血量、手术时间、住院时间、转重症监护室率以及子宫切除率均低于对照组(P＜0.05);两组患者产褥感染的发生率比较差异无统计学意义(P＞0.05);两组患者术后均未出现下肢动、静脉血栓.结论 腹主动脉预置球囊阻断术应用于凶险性前置胎盘患者的剖宫产术,能有效控制术中出血,减少输血量,降低子宫切除率,缩短手术及住院时间,提高剖宫产手术的安全性.

目的:探究经皮腔内血管成形术用于糖尿病足患者临床的应用效果.方法:研究对象选择为到我院进行治疗的糖尿病足患者,选取患者共计70例,收入患者的治疗时间为2017.12-2019.12,采用随机数字表法将患者均分为实验组和对照组两组,每组患者为35例,对照组给予保守治疗,实验组患者在保守治疗的基础上,采用经皮腔内血管成形术,分析治疗结果.结果:实验组患者足背动脉直径、患肢皮温指标变化、溃疡面积与对照组相比,统计学意义存在(P＜0.05).实验组治疗有效率高于对照组,患肢截肢率低于对照组,统计学意义存在(P＞0.05).结论:糖尿病足患者采用经皮腔内血管成形术的治疗有效率较高,截肢率较低,值得推广.

Objective To investigate the clinical efficacy of 125I seed implantation in the treatment of recurrent non-small cell lung cancer after radiation and chemotherapy. Methods 14 patients of recurrent non-small cell lung cancer after radiation and chemotherapy were treated with 125I seed implantation, postoperative complications were observed, and 2 months 125I seed implantation, the effect was evaluated by CT imaging. Results All the 14 patients completed the implantation at one time, and postoperative complications mainly included puncture bleeding, pneumothorax and so on. The effective rate of treatment was 7.1％, 42.9％, 64.3％ and 78.6％, respectively. On the second month, 4 th month, 6 th month and 12 th month after implantation, the 1-year survival rate was 85.7％. Conclusion 125I seed implantation is safe and effective in the treatment of recurrent non-small cell lung cancer after radiation and chemotherapy, which is worthy of clinical promotion.

Objective To explore the value of CTA in the diagnosis and treatment of gastrointestinal bleeding.Methods The clinical data of 60 patients with gastrointestinal hemorrhage were analyzed retrospectively, including preoperative and postoperative CTA examination and DSA data. The total time of interventional embolization, the time of exposure, the number of radiographs and the total radiation dose were recorded at the same time. There were 30 patients in the experimental group, who were examined by CTA before operation, and there were 30 patients in the control group who did not undergo CTA examination before the operation. CTA examination was performed 1 days after operation in the two groups, and the data above were analyzed statistically. Results The median age, the proportion of men and women and the median weight of the patients in the experimental group and the control group were basically the same, the difference was not statistically significant. The total time (65±12) min, the exposure time (218±22)s, the number of angiography (4±1) and the total radiation dose (468±35)mGy in the experimental group were significantly higher than those in the control group(81±15)min, (309±36)s,(6±2), (587±48)mGy (P <0.05). All cases underwent CTA after embolization, and gastrointestinal bleeding was found in 3 cases, followed by interventional embolization again, and CTA indicated bleeding stopped. No definite bleeding signs were found in all patients during the follow-up.Conclusion CTA examination before interventional embolization can evaluate the location of bleeding, the flow of bleeding and the shape of blood vessel, which have important guiding effect on the operation. It can shorten the total time of interventional embolization, the time of exposure, the number of radiography and the dose of radiation. The CTA examination after the interventional embolization can evaluate the curative effect and find the bleeding lesion in time, so it is worthy of clinical promotion.
