Primary congenital abdominal aortic aneurysm associated with renovascular hypertension in pediatric patient.

Idiopathic congenital abdominal aortic aneurysm (AAA) is rare, with only a few cases reported in the literature. We present a case of a 3-year-old girl with a fusiform AAA measuring 19 mm in segments 4 and 5, associated with renal artery stenosis and severe hypertension. She was treated with three antihypertensive medications.

Rapid detection of ricin at trace levels in complex matrices by asialofetuin-coated beads and bottom-up proteomics using high-resolution mass spectrometry.

Ricin is a toxic protein regarded as a potential chemical weapon for bioterrorism or criminal use. In the event of a ricin incident, rapid analytical methods are essential for ricin confirmation in a diversity of matrices, from environmental to human or food samples. Mass spectrometry-based methods provide specific toxin identification but require prior enrichment by antibodies to reach trace-level detection in matrices.

The Value of Aortic Volume and Intraluminal Thrombus Quantification for Predicting Aortic Events after Endovascular Thoracic Aneurysm Repair.

To assess the ability of the aortic aneurysm volume (AAV), aneurysmal lumen volume (ALV), and aneurysmal thrombus volume (ATV) to predict the need for aortic reintervention when using the maximal aortic diameter as a reference. This monocentric retrospective study included 31 consecutive patients who underwent successful thoracic endovascular aortic repair (TEVAR) to treat an atheromatous thoracic aortic aneurysm. All patients underwent clinical and computed tomography angiography (CTA) for 3 years after TEVAR.

A ruptured penetrating atherosclerotic ulcer of the ascending aorta: a case report of an endovascular repair with extending the length of the aortic coverage by debranching the innominate artery.

Background: An endovascular approach to the management of a ruptured plaque in the ascending aorta may be an alternative to open surgery in high-risk patients. This option may become inevitable due to the number of elderly patients unfit for open cardiac surgery. There are very few stent grafts able to fit the ascending aorta and in emergency cases, most medical teams have been limited to current thoracic aortic endografts, the shortest of which measure 10 cm.

Preoperative Inferior Mesenteric Artery Embolization is a Cost-effective Technique that May Reduce the Rate of Aneurysm Sac Diameter Enlargement and Reintervention After EVAR.

Background: Type II endoleaks are the most common complications after endovascular repair of abdominal aortic aneurysms (EVARs). Some studies have shown the benefit of preventive inferior mesenteric artery (IMA) embolization, but its efficacy and cost-effectiveness continue to be controversial. The aim of this study was to evaluate the efficacy of this procedure on the increase in aneurysmal sac diameter during follow-up.
