Objective: Penetrating atherosclerotic ulcer generally occurs in elderly patients with systemic atherosclerosis, predominantly in the descending thoracic aorta, and it is uncommon in the infrarenal aorta. We reviewed our experience of endovascular treatment of penetrating aortic ulcer in the infrarenal aorta.
Methods: In the last 4 years, out of 348 patients who underwent abdominal aortic procedures, a total of 13 patients (12 men and 1 woman) were found to have an abdominal penetrating aortic ulcer, corresponding to an incidence of 3.7%. Mean age was 73+/-7 years. All patients had hypertension. Three lesions were discovered incidentally and 10 were symptomatic. All patients underwent endovascular treatment in the operating room. Follow-up included CT-A control at 1, 4 and 12 months after the intervention, and yearly thereafter.
Results: Primary technical success was 100%. No postoperative death was observed. Mean operative time was 100+/-29 min. Mean blood loss was 168+/-133 ml. No patient required intensive care unit stay. We observed one major complication (transient ischemic attack). Mean hospital stay was 4+/-1 days. During a mean follow-up period of 26 months no endoleak, aneurysm evolution or stent graft failure was recognized in any patient. One patient died 24 months after the intervention after a stroke.
Conclusions: In our experience, endovascular or repair of infrarenal aortic ulcer appears feasible, and midterm results satisfactory.

Thoracic Endovascular Aortic Repair for Penetrating Aortic Trauma.
Ann Vasc Surg
January 2025
Division of Vascular Surgery, University of Maryland, Baltimore, Maryland.
Background: Thoracic Endovascular Aortic Repair (TEVAR) reduced mortality for blunt aortic injury (BAI) from 30-50% to < 10%; however, penetrating traumatic aortic injury (PAI) remains highly lethal (>40% mortality). This study's goal is to determine outcomes of TEVAR for PAI.
Methods: Patients undergoing TEVAR for traumatic aortic injuries were identified from the Vascular Quality Initiative database from 2011-2022.

Acute aortic syndrome (AAS) encompasses a range of life-threatening conditions, including classical dissection, intramural hematoma, and penetrating aortic ulcer. Each of these conditions presents distinct clinical characteristics and carries the potential to progress to rupture. Because AAS can be asymptomatic or present with diverse symptoms, its diagnosis requires clinical evaluation, risk scoring, and biomarkers such as D-dimer (DD), C-reactive protein (CRP), homocysteine, natriuretic peptides (BNP), and imaging modalities like computed tomography (CT), magnetic resonance imaging (MRI), and echocardiography.

The term acute aortic syndrome (AAS) refers to a range of different entities, including dissection, intramural haematoma and penetrating atherosclerotic ulcer. Patients with chronic renal disease and particularly those with dominant polycystic kidney disease are susceptible to this pathology, given the underlying renal arteriopathy and hypertension. Imaging plays a crucial role in diagnosing, grading and guiding management of these patients, with computed tomography angiography (CTA) being on the frontline.

A woman in her 70s with hypertension, breast cancer and diverticulosis underwent laparoscopic anterior resection for a tubule-villous adenoma, converted to open Hartmann's with aorto-bi-iliac bypass due to a vascular injury. Intraoperative complications included haem-o-lok penetration of the calcified aorta, necessitating vascular team intervention. Postoperative issues included bilateral popliteal artery emboli requiring embolectomy and fasciotomy, and a parastomal abscess.

Indian J Thorac Cardiovasc Surg

Department of Engineering Design, Indian Institute of Technology Madras, Chennai, India.
Purpose: Despite significant improvements in the design and performance of continuous flow left ventricular assist devices (CFLVADs), one of the most important reasons hampering further penetration of this technology is the occurrence of adverse events, especially strokes. One of the well-known risk factors for strokes is hypertension which is particularly common in patients undergoing a CFLVAD implant. While the device is implanted in the heart, strokes happen due to pathology in the brain and we hypothesised that modelling the blood flow in the circle of Willis might shed light on the causation of strokes in this situation.
