Association of Narrow Anterior Communicating Artery or Contralateral A1 Segment with Poor Outcomes After Mechanical Thrombectomy.

Contralateral A1 and AComA aplasia/hypoplasia are critically important in distal ICA T occlusion as the protective collateral blood supply from the circle of Willis via the anterior communicating artery is compromised. Although the terms aplasia/hypoplasia are used broadly in the literature, the need for concrete measurements and data on their clinical significance is apparent. Features of the individual anatomy of the circle of Willis may determine patient outcomes.

A multi-center study of the MicroNET-covered stent in consecutive patients with acute carotid-related stroke: SAFEGUARD-STROKE.

Introduction: Acute carotid-related stroke (CRS), with its large thrombo-embolic load and large volume of affected brain tissue, poses significant management challenges. First generation (single-layer) carotid stents fail to insulate the athero-thrombotic material; thus they are often non-optimized (increasing thrombosis risk), yet their use is associated with a significant (20-30%) risk of new cerebral embolism.

Aim: To evaluate, in a multi-center multi-specialty investigator-initiated study, outcomes of the MicroNET-covered (cell area ≈ 0.

Circle of Willis Configuration and Thrombus Localization Impact on Ischemic Stroke Patient Outcomes: A Systematic Review.

: The published literature highlights the fact that the integrity of the Circle of Willis has a direct impact on stroke outcome, especially in cases of distal internal carotid T occlusion. The aim of this study was to review the available data on the Circle of Willis configuration and thrombus location impact on patient outcome in cases of ischemic stroke. : A systematic search according to PRISMA guidelines was performed in PubMed, Cochrane, and EMBASE databases to identify studies investigating the influence of Circle of Willis variants on ischemic stroke outcomes published up to March 2023.

Abdominal Aortic Aneurysm Diameter versus Volume: A Systematic Review.

Unlabelled: Recently, AAA volume measurement has been proposed as a potentially valuable surveillance method in situations when diameter measurement might fail.

Objective: The aim of this systematic review was to analyze the results of previous studies comparing AAA diameter and volume measurements.

Methods: A systematic search in PubMed, Cochrane, and EMBASE databases was performed to identify studies investigating the use of diameter and volume measurements in AAA diagnosis and prognosis in English, German, and Russian, published until December 2022.

Measurement of Revascularization Effect Using Near Infrared Spectroscopy in Below the Knee Arteries.

Background: Current methods evaluating tissue ischemia are based mainly on evaluating blood flow and not tissue perfusion. However, diabetes mainly affects small vessels and blood flow evaluation is insufficient. The aim of the trial was to evaluate the feasibility of NIRS in measuring perfusion changes during chronic total occlusion (CTO) revascularization in below the knee (BTK) arteries.

Enterocutaneous Fistula: Open Repair after Unsuccessful Stenting-A Case Report.

Enterocutaneous fistula (ECF) is an abnormal connection between the gastrointestinal tract and the skin; by some estimates, it represents 88.2% of all fistulae. It can either develop spontaneously due to underlying malignancy, inflammatory bowel disease, radiation exposure, or, more commonly, as a complication of gastrointestinal surgery.

The use of near-infrared spectroscopy in the diagnosis of peripheral artery disease: A systematic review.

Background: Peripheral arterial disease is a stenosis or occlusion of peripheral arteries that results in compromised blood flow and muscle ischemia. The available diagnostic methods are mostly used to measure and visualize blood flow and are not useful in the evaluation of perfusion, especially in diabetic patients, which is now considered to be a research priority by most of the vascular societies around the world as this is still a relatively poorly studied phenomenon.

Objective: The aim of this review is to explore the clinical significance of muscle tissue oxygenation monitoring in lower-extremity peripheral artery disease diagnosis using the near-infrared spectroscopy method.

A Bleeding Uretero-Arterial Fistula: Open Repair After Unsuccessful Endovascular Treatment.

Introduction: Uretero-arterial fistula (UAF) poses major challenges in management and diagnosis due to the rarity of this condition and associated high morbidity/mortality rates.

Methods: We describe a case of a UAF associated with previous aorto-biiliac grafting, ureteric stenting and right nephrectomy because of chronic pielonephritis and complicated by surgical site infection. This case illustrates a very complex pathology, with a challenging diagnosis and multiple treatment options.
