概括

大动脉疾病的奥扎基手术显示出稳定的血液动力学和良好的左心室重塑. 这种大动脉置换技术提供了低的重复手术率,支持其持续的临床使用.

科学领域:

心血管外科心血管外科
生物材料科学生物材料科学
医疗器械医疗器械

背景情况:

奥扎基手术,利用自身心脏为主动脉置换,于2007年推出.
这种技术的中期结果和门性能数据在很大程度上仍未报告.

研究的目的:

为了评估纵向血液动力学和左心室逆向重塑后的奥扎基手术.
为了评估接受原始Ozaki手术队列的患者的重新手术率和存活率.

主要方法:

分析了从2007年4月到2021年5月期间接受奥扎基手术的1,196名患者.
数据包括患者人口统计学,门病理学,并发手术,临床结果和心声回声图.
使用非线性混合效应回归评估了纵向的性能,并使用时间到事件方法分析了重新操作/死亡率.

主要成果:

大动脉的平均梯度在10年内保持稳定和低 (7.4-8.2 mm Hg).
左心室质量指数在手术后显著下降 (141到90g/m2).
十年生存率为78%,无需重新手术的比例为92%,吐率低但不断增加 (10年后为6.6%).

结论:

奥扎基手术的结果是功能性大动脉置换,持续的低梯度.
观察到显著的左心室逆转型改造和有利的长期存活率和复手率.
虽然大动脉反随着时间的推移而增加,但整体风险概况支持继续使用奥扎基手术.

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...
