在PubMed上查看摘要
概括
此摘要是机器生成的。计算机断层扫描 (CTA) 衍生的外周动脉评分系统 (PACSS) 和其修改版 (mPACSS) 预测慢性肢体威胁性缺血症 (CLTI) 患者的膝下 (BTK) 重血管化的结果.
科学领域
- 血管外科
- 干预性放射学
- 医学成像
背景情况
- 膝下内血管再循环 (BTK) 是慢性肢体威胁性缺血 (CLTI) 的关键治疗方法.
- 结果受缺血严重程度,解剖学,并发症和血管化的影响.
- 目前基于血管造影的外周动脉评分系统 (PACSS) 在灵敏度和观察者间一致性方面存在局限性.
研究的目的
- 通过计算机断层扫描 (CTA) 来评估BTK内血管干预后原始和修改的PACSS (mPACSS) 的预后价值.
- 将基于CTA的化评分与传统方法的可靠性进行比较.
主要方法
- 在BTK干预后6个月内接受CTA的419名CLTI患者.
- 评估原始PACSS和修改后的PACSS (mPACSS),其中包括整个目标容器的化.
- 主要结局:3个月的肢体恢复和没有截肢的生存率 (AFS).
主要成果
- 在39. 7%的肢体中发现了PACSS4,并与年龄,糖尿病和较高的缺血阶段等不良因素相关.
- 无论是PACSS 4还是mPACSS ≥5都是下肢3个月恢复和AFS的显著预测因素.
- 在技术成功,初级通透性或整体存活率方面没有发现显著差异.
结论
- 在BTK干预后,CTA衍生的PACSS和mPACSS是可靠和独立的预测器.
- 这些基于CTA的评分比基于血管造影的方法在CLTI患者的手术前评估中提供了更好的可靠性.
- 需要在更大的群体中进行进一步的研究,以在不同的临床环境中探索PACSS和mPACSS.

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
