Comparing outcomes after open and endovascular chronic mesenteric ischemia reva...

Abstract Introduction: Chronic mesenteric ischemia (CMI) is a rare but life-threatening disease. This study aimed to analyze the safety and effectiveness of open (OR) and endovascular (ER) revascularization and respective outcomes in a consecutive series of CMI patients. Methods: From 2013 to 2023, all CMI patients treated with OR and ER were retrospectively identified. Demographics, comorbidities, clinical pre...

Chronic limb-threatening ischemia under the age of 50 - a single-center 12-year...

Abstract Introduction: Premature peripheral artery disease (PAD), defined as occurring before or at the age of 50, is a poorly studied subset of PAD due to its low incidence. It has been associated with a higher risk of progression to chronic limb-threatening ischemia (CLTI), major adverse limb events and mortality. Etiology is multifactorial, with genetics and environmental causes at play, with the most common...

The role of femoropopliteal calcification pattern on outcomes after endovascula...

Abstract Introduction: Peripheral arterial calcification is typically most prominent in the femoropopliteal (FP) segment, and its effect on endovascular treatment (EVT) processes and outcomes is poorly understood. This study aimed to evaluate the impact of the pattern of FP calcification on EVT outcomes. Methods: We designed a retrospective, single-center, comparative study. From January 2023 to February 2024, ...

Bowel Obstruction after Liver Transplant: A Rare Cause

Fenestrated Physician-Modified Endografts (PMEGs) - a viable option for urgent ...

Abstract Introduction: Fenestrated and branched stent graft technology has come a long way over the past few years, enabling the treatment of complex juxtarenal aneurysms, thoracoabdominal aneurysms, and arch pathologies. Many innovations have been developed, namely device and delivery optimization and technical tricks. These concepts have proven to work well when there is sufficient time to plan and manufactur...

Portuguese Pancreatic Club Perspectives on Endoscopic Ultrasound-Guided and Sur...

Abstract Pancreatic neuroendocrine tumors (panNETs) are a group of neoplasms with heterogenous biological and clinical phenotypes. Although historically regarded as rare, the incidence of these tumors has been increasing, mostly owing to improvements in the detection of small, asymptomatic tumors with imaging. The heterogeneity of these lesions creates significant challenges regarding diagnosis, staging, and tre...

Deep Learning and Minimally Invasive Endoscopy: Panendoscopic Detection of Pleo...

Abstract Introduction: Capsule endoscopy (CE) is a minimally invasive exam suitable of panendoscopic evaluation of the gastrointestinal (GI) tract. Nevertheless, CE is time-consuming with suboptimal diagnostic yield in the upper GI tract. Convolutional neural networks (CNN) are human brain architecture-based models suitable for image analysis. However, there is no study about their role in capsule panendoscopy....

A Gastric Lesion Revealing a Small-Cell Lung Cancer: A Rare Case

Artificial Intelligence and Capsule Endoscopy: Automatic Detection of Small Bow...

Abstract Introduction: Capsule endoscopy has revolutionized the management of patients with obscure gastrointestinal bleeding. Nevertheless, reading capsule endoscopy images is time-consuming and prone to overlooking significant lesions, thus limiting its diagnostic yield. We aimed to create a deep learning algorithm for automatic detection of blood and hematic residues in the enteric lumen in capsule endoscopy...

Methicillin resistant Staphylococcus aureus infection in vascular surgery patients

Abstract Introduction: Surgical site infections are associated with devastating consequences in vascular surgery patients but the data on Methicillin Resistant Staphylococcus aureus (MRSA) infection among those remains scant and conflicting. Most vascular surgery antibiotic prophylaxis assume that all patients submitted to surgery are tested prior to the intervention or that all patients with risk factors for M...
