概括

一种罕见的动脉变体,持续原始的低分泌动脉 (PPHA),在患有动脉狭窄的患者中引起后部循环中风症状. 需要创新的支架技术才能成功治疗.

科学领域:

神经学神经学
血管外科血管外科
放射学放射学是一门学科.

背景情况:

持久性原始性低分泌动脉 (PPHA) 是一种罕见的动脉-脊椎骨基动脉变异的罕见变体.
当PPHA与动脉狭窄并存时,通常会出现前部循环缺血症状.

研究的目的:

报告一个独特的常见动脉狭窄病例,PPHA仅呈现后部循环缺血症状.
突出这些病例的诊断挑战和创新的治疗策略.

主要方法:

一名65岁的女性患有复发的后部循环缺血症状,接受了成像检查.
确定了左侧CCA狭窄和供应后部循环的PPHA.
在PPHA分叉处使用创新的远端气球保护进行了动脉支架.

主要成果:

患者呈现出由于CCA狭窄和PPHA的排他性后部循环缺血症状.
标准的远距离保护是不可行的;创新的远距离气球保护成功地应用了.
患者经历了一个有利的术后过程,症状得到缓解.

结论:

与PPHA相关的带狭窄可以表现为后部循环症状,使诊断复杂化.
了解像PPHA这样的解剖变异对于有效治疗至关重要.
在复杂的情况下,创新的栓塞保护策略可能是成功的动脉支架所必需的.

Arteries of the Head and Neck

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

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...
