概括

在门静脉栓塞后,未来的肝残留物 (FLR) 中的度较高与FLR缩的增加有关. 双能CT (DECT) 可以量化这种含量,可能作为肝功能生物标志物.

科学领域:

肝胆道手术是肝胆道的手术.
放射学放射学是一门学科.
在瘤学瘤学.

背景情况:

门静脉栓塞 (PVE) 用于在主要肝切除术之前诱导未来肝残留物 (FLR) 的缩.
评估FLR缩对于预测术后肝功能和患者结果至关重要.
目前用于评估FLR缩的方法可能无法完全捕捉功能方面.

研究的目的:

为了研究FLR缩和PVE后FLR含量之间的相关性.
评估双能计算断层扫描 (DECT) 的实用性,以量化FLR中的含量.
探索含量作为FLR功能的潜在生物标志物.

主要方法:

对39名患有胆道癌的患者进行前性研究.
在直接向门静脉注射有的对比剂后进行DECT.
在FLR中计量度和含量.
计算FLR缩和运动生长率 (KGR).

主要成果:

在FLR中早期阶段的含量与高度 (DH) (r=0.380,p=0.038) 和KGR (r=0.401,p=0.028) 有显著的相关性.
在FLR中晚期含量也与DH (r=0.403,p=0.011) 和KGR (r=0.337,p=0.036) 有显著的相关性.
在含量和缩指数之间观察到温和的相关性.

结论:

在FLR中含量增加与PVE后更大的FLR缩有关.
基于DECT的定量可能为FLR功能提供补充信息.
需要进一步的研究来确定DECT衍生的含量作为FLR功能的预测生物标志物.

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow

Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

Effect of Hepatic Disease on Pharmacokinetics: Pathophysiologic Assessment and Liver Function Test

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...
