概括

高级动脉分叉 (HCB) 很难定义. 这项研究使用下角 (AM) 和C3脊椎水平来定义HCB,显示出比以前想象的更高的患病率.

科学领域:

人体解剖学解剖学解剖学
血管外科血管外科
放射学放射学是一门学科.

背景情况:

高水平动脉分叉 (HCB) 提出了外科手术的挑战.
对于HCB的最终参考点仍然不清楚.
下 (AM) 的角度是动脉手术暴露的重要因素.

研究的目的:

为了调查动脉分叉 (CB) 的水平.
定义HCB与下 (AM) 和脊椎水平的角度相关.
为了测量从HCB到ipsilateralAM的垂直距离.
根据脊椎水平,评估错误地将手术挑战性CBs归类为低CBs (LCBs) 的比例.

主要方法:

对接受部计算机断层扫描血管造影的患者进行了回顾性研究.
基于C3脊椎水平和/或ipsilateralAM的HCBs的分类.
对来自86名患者的172名CB的CB位置相对于C3和AM的分析.

主要成果:

冠状动脉分叉 (CB) 最常见的是C3 (44.19%),而下角 (AM) 通常在C2 (51.16%).
在基于脊椎水平的10.47%和基于AM的20.35%中确定了HCB.
在考虑C3和AM时,8.72%的CB被归类为HCB,11.63%只使用脊椎水平时被错误归类为LCB.

结论:

使用下角 (AM) 定义 HCB 识别了更多的高层分叉,而不是仅使用 C3 脊椎水平.
在考虑AM时,可能仅基于脊椎水平被归类为LCB的显著比例的CB实际上可能是HCB.
下的角度为定义HCB和评估手术难度提供了更全面的参考.

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...

Local Anesthetics: Clinical Application as Spinal Anesthesia

Local Anesthetics: Clinical Application as Spinal Anesthesia

Spinal anesthetics are given during lower abdomen and limb surgeries to block sensory and motor neurons. They are administered in the mid to low lumbar regions, primarily acting on the cauda equina's nerve roots. The blockade level depends on the local anesthetic (LA) concentration. Usually, low LA concentrations are sufficient to block sensory fibers, while only high LA concentrations block motor fibers. Other factors like injection volume and speed, the patient's posture, and the drug...
