Detection of Atherosclerosis by Small RNA-Sequencing Analysis of Extracellular Vesicle Enriched Serum Samples.

Atherosclerosis can occur throughout the arterial vascular system and lead to various diseases. Early diagnosis of atherosclerotic processes and of individual disease patterns would be more likely to be successful if targeted therapies were available. For this, it is important to find reliable biomarkers that are easily accessible and with little inconvenience for patients.

Effect of endoleaks on changes in aortoiliac volume after endovascular repair for abdominal aortic aneurysm.

Purpose: To evaluate changes in aortoiliac volume after endovascular repair (EVAR) for abdominal aortic aneurysm (AAA) in patients with and without endoleaks.

Materials And Methods: We retrospectively analyzed 137 patients who underwent EVAR for AAA. We manually measured the aortoiliac volume on pre-procedural baseline CT angiograms (CTAs) and post-procedural follow-up CTAs.

Type A aortic dissection model to improve endovascular research and technologies.

Objective: Type A aortic dissection is a life-threatening disease requiring immediate surgical treatment. With emerging catheter-based technologies, endovascular stent-graft implantation to treat aneurysms and dissections has become a standardized procedure. However, endovascular treatment of the ascending aorta remains challenging.

[Computed tomography angiography as the basis for optimized therapy planning before endovascular aneurysm repair (EVAR)].

Computed tomography angiography (CTA) of the aorta is an accepted standard diagnostic procedure for preoperative evaluation and planning of endovascular treatment of abdominal aortic aneurysms (endovascular aortic repair EVAR). The CTA method delivers all relevant anatomical and morphological information on the underlying pathology of the aorta and pelvic axes. Various software solutions are available for multiplanar reconstruction of the CT data for exact measurement of the access routes and landing zones and are essential components of individualized operation planning.

A comparison between contrast-enhanced ultrasound imaging and multislice computed tomography in detecting and classifying endoleaks in the follow-up after endovascular aneurysm repair.

Background: This study compared contrast-enhanced ultrasound (CEUS) imaging and multislice computed tomography (MS-CT) angiography in detecting and classifying endoleaks in the follow-up of patients after endovascular aneurysm repair (EVAR).

Methods: This retrospective study consisted of 171 patients with CEUS imaging and MS-CT angiography follow-up examinations after EVAR. During follow-up, 489 CEUS and 421 MS-CT examinations were assessed.
