概括

管道栓塞装置 (PED) 在胎儿类型的后沟通动脉 (fPComA) 动脉瘤中达到75%的阻塞率,与非fPComA病例相匹配. 远端PED放置与治疗这些复杂的大脑动脉瘤的成功结果有关.

科学领域:

血管神经学血管神经学
干预性神经放射学干预性神经放射学
脑血管外科脑血管外科

背景情况:

胎儿类型的后沟通动脉 (fPComA) 是威利斯圆的常见变体.
与非fPComA动脉瘤相比,fPComA动脉瘤的治疗结果可能不同.
之前的研究表明,使用流量转移治疗的fPComA动脉瘤的阻塞率较低.

研究的目的:

评估管道栓塞装置 (PED) 治疗fPComA动脉瘤的疗效.
在使用PED治疗的fPComA病例中,确定成功消灭动脉瘤的预测因素.
为了比较fPComA与非fPComA动脉瘤的PED治疗结果.

主要方法:

用PED治疗fPComA和非fPComA动脉瘤的患者的回顾性分析 (2013-2023年).
收集的数据包括人口统计,解剖学,动脉瘤特征,干预技术和结果 (闭塞,并发症).
血管造影随访评估了动脉瘤封闭;单变量分析比较了封闭率.

主要成果:

在96个PComA动脉瘤中,19个是fPComA变体. 三名患者失去了随访时间.
对于fPComA动脉瘤,PED在一年内实现了75%的完全/近乎完全闭塞 (>90%),与非fPComA病例相匹配.
在M1段的远端PED尖端放置与完全的fPComA动脉瘤封闭有显著的关联 (p=0.049). 在2名轻微中风的患者中发生了静脉栓塞.

结论:

经过PED治疗,fPComA动脉瘤的闭塞率达到75%,超过了之前的研究.
佩德安置的技术显著影响了高封闭率.
对于fPComA动脉瘤来说,PED是一种潜在的安全和有效的选择,技术是关键因素.

Fetal Circulation

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

The Arch of Aorta

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Aneurysm III: Interprofessional Care

Aneurysm III: Interprofessional Care

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
