概括

在民动脉动脉瘤 (PAA) 中,内血栓的体积显著与内流量减少相关. 较高的血栓负载表明较差的结果,特别是在紧急情况下.

科学领域:

血管外科血管外科
动脉瘤研究动脉瘤研究
医学成像分析医学成像分析

背景情况:

与选择性手术相比,对形动脉动脉瘤 (PAA) 的紧急手术导致患者的结果更差.
有限的肌肉血管流失是导致PAA紧急病例结果较差的主要因素.
了解PAA形态对骨干流失的影响对于预测手术成功至关重要.

研究的目的:

为了研究PAA直径,体积和内血栓负荷之间的关系.
为了确定这些PAA特征与手术前肌肉血管流失的相关性.
确定PAA患者的预后结果的预后指标.

主要方法:

对经过手术治疗的PAA患者的回顾性分析.
半自动定量CT分析PAA直径,体积和内血栓体积.
在PAA形态参数和专属肌肉血管数量之间的相关性分析.

主要成果:

内血栓 (ILT) 容量显示出与减少内流量 (r=-0.34,p=0.01) 最强的相关性.
在PAA直径和面流水之间没有发现显著的相关性 (r=-0.17,p=0.1).
减少骨外流量显著与无截肢存活率受损相关 (p=0.01).
血栓体积指数在紧急PAA病例中较高.

结论:

内血栓的体积是减少PAA中内流失的关键预测因素.
ILT量应被认为是预后重要因素,特别是在PAA快速增长的情况下.
基于CT的ILT负载评估可以帮助PAA患者的风险分层.

关键词:

脊柱动脉动脉瘤是一种动脉瘤.动脉瘤的体积和体积.农村的流失和流失.它的直径是直径直径的直径.内血栓是指内血栓.

Veins of Lower Limbs

Veins of Lower Limbs

The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...
