2025年3月11日 · Intravascular ultrasound (IVUS) has become an essential tool for endovascular procedures, particularly during complex interventions. The benefits include improved visualization of vascular and extravascular anatomy, reduced complication rates, and enhanced accuracy during catheter-based interventions.

2020年2月1日 · IVUS is routinely used in procedures such as transjugular intrahepatic portosystemic shunt (TIPS)/direct intrahepatic portosystemic shunt (DIPS), May-Thurner stenting, guiding percutaneous fenestration in the setting of aortic dissection, inferior vena cava (IVC) filter placement (without cavography and/or fluoroscopy in the setting of an ...

IVUS is no longer a luxury; it is a key tool to ensure optimal outcomes in endovascular intervention for PAD. The use of IVUS is beneficial both preintervention in guiding therapy and postintervention in understanding the efficacy of treatment.

There are several potential roles for IVUS with CTO interventions due to its high resolution cross sectional imaging of the coronary vessels. IVUS can help direct crossing total occlusions by showing the location of the wire in plaque, media/adventitia, or extravascular locations. These may lead to choosing

Intravascular ultrasound (IVUS) can provide real-time visualization of the hepatic and portal vein anatomy, potentially reducing the portal vein (PV) access time. The purpose of this study is to compare the time to get PV access and radiation dose between IVUS-guided (iTIPS) and conventional TIPS (cTIPS).

Learn how to interpret IVUS cross-sections and pullbacks for assessing lesion morphology for IVUS-guided PCI. Case Reviews Explore twenty-one detailed cases using IVUS for left main, bifurcations, calcified lesions, SCAD, ISR, and other complex interventions.

2023年3月17日 · Studies have reported that intravascular ultrasound (IVUS) guidance for transjugular intrahepatic portosystemic shunt (TIPS) creation decreases the number of needle passes, incidence of capsular perforation, procedure duration, contrast medium volume used, fluoroscopy time, and radiation dose (1–5).

Intravascular ultrasound (IVUS) has become an essential tool for endovascular procedures, particularly during complex interventions. The benefits include improved visualization of vascular and extravascular anatomy, reduced complication rates, and enhanced accuracy during catheter-based interventions.

IVUS is the only imaging modality that can differentiate a static/fixed/true stenosis from a dynamic stenosis, preventing unnecessary stenting, and because it is highly sensitive and accurate, it minimizes the chances of “missing” lesions that could compromise outcome .

IVUS guidance during TIPS creation improves procedural metrics such as radiation dose, contrast agent volume, procedure time, and technical success rate and is particularly beneficial in technically challenging cases (e.g., in patients portal vein thrombosis, small or variant portal vein anatomy, Budd-Chiari syndrome, or liver masses).

To assess whether intravascular ultrasound (IVUS) guidance in the creation of transjugular intrahepatic portosystemic shunts (TIPS) results in improved procedural success, as measured by decreased radiation exposure, procedure time, contrast volume required, and transhepatic needle passes performed.

2022年5月18日 · IVUS guidance for TIPS procedures facilitates obtaining PV access through direct real-time visualization of the HV and PV puncture sites and other relevant anatomic structures. IVUS guidance during TIPS creation improves procedural metrics such as radiation dose, contrast agent volume, procedure time, and technical success rate.

2022年10月12日 · The authors elegantly describe the types of IVUS probes and their applications not only in facilitating the portal vein puncture but also in parenchymal tract measurement and stent placement. In the literature, guidance for TIPS by IVUS has been shown to reduce the number of needle passes for entering the portal vein and radiation exposure [ 2 ].

IVUS是通过导管技术将微型超声探头送入血管腔内，通过超声波扫描和反射，从而提供在体血管腔内影像，其能清晰显示管壁结构的厚度、管腔大小和形状等，精确地测量血管腔径及截面积，甚至可以辨认钙化、纤维化和脂质池等病变。 因此，IVUS可为术者进一步介入治疗提供依据，达到精选支架、精准疗效的目的。 同时，也可通过IVUS确认植入后支架是否贴壁和扩张良好，有无支架边缘夹层，有无组织脱垂，有无物理丢失，支架压缩等情况。 IVUS作为冠脉血管检查的新“金 …

IVUS is the only imaging modality that can differentiate a static/fixed/ true stenosis from a dynamic stenosis, preventing unneces-sary stenting, and because it is highly sensitive and accurate, it minimizes the chances of “missing” lesions that could compromise outcome (Figure 8). However, IVUS technology is expensive and lacks reim-

IVUS image interpretation is easy with IVUS 123 Essentials. This guide, developed in partnership with physicians, provides a quick and easy methodology for every PCI procedure, helping to determine treatment strategy, guide stent placement, and assess procedural results to optimize coronary outcomes.
