Role of Antiplatelet Therapy in Patients Managed for Complex Aortic Aneurysms using Fenestrated or Branched Endovascular Repair.

Objective: Despite the increasing number of fenestrated and branched endovascular aortic repair (F/B-EVAR) procedures, evidence on post-operative antiplatelet therapy is very limited. This study aimed to investigate the role of single antiplatelet therapy (SAPT) vs. double antiplatelet therapy (DAPT) after F/B-EVAR in 30 day and follow up outcomes.

Maximal Systolic Acceleration and Near-Infrared Fluorescence Imaging With Indocyanine Green as Predictors for Successful Lower Extremity Revascularization.

Background: Patients with lower extremity arterial disease (LEAD) frequently require revascularization procedures. Currently used diagnostic methods are insufficient in predicting successful outcomes and focus on macrovascular rather than microvascular state. Several promising modalities to increase diagnostic accuracy are emerging, including maximal systolic acceleration (ACC), measured by duplex ultrasound (DUS).

The association between sarcopenia and adverse outcomes after complex endovascular aortic repair.

Background: Sarcopenia is identified as a predictive factor for adverse outcomes after complex endovascular aortic repair (complex EVAR). Consensus on preferred parameters for sarcopenia is not yet reached. The current study compares three CT-assessed parameters on their association with adverse outcomes after complex EVAR.

Therapeutic management of in-stent thrombosis after thoracic endovascular aortic repair for blunt thoracic aortic injury in a coronavirus disease 2019 patient.

A 27-year-old man underwent thoracic endovascular aortic repair for blunt thoracic aortic injury. Fourteen months later, he presented with intermittent paraplegia, congestive heart failure, and a decline of kidney function as a result of high-grade aortic stenosis caused by in-stent thrombosis. He had a concurrent infection with coronavirus disease 2019.

Increased Aortic Exclusion in Endovascular Treatment of Complex Aortic Aneurysms.

Purpose: Perioperative risk assessments for complex aneurysms are based on the anatomical extent of the aneurysm and do not take the length of the aortic exclusion into account, as it was developed for open repair. Nevertheless, in the endovascular repair (ER) of complex aortic aneurysms, additional segments of healthy aorta are excluded compared with open repair (OR). The aim of this study was to assess differences in aortic exclusion between the ER and OR of complex aortic aneurysms, to subsequently assess the current classification for complex aneurysm repair.

Secondary objectives are to analyze the correlation between ablation margins and local recurrence and to assess efficacy.

Materials And Methods: This study is a prospective, multicenter, non-experimental, non-comparative, open-label study.

Functional Performance After Complex Endovascular Aortic Repair: A Single-Center Retrospective Cohort Study.

Purpose: Complex endovascular aortic repair (EVAR) procedures provide a treatment option for patients with aortic aneurysms involving visceral branches. Good technical results and short-term outcomes have been reported. Whether complex EVAR provides acceptable outcomes is not clear.

Perfusion Parameters in Near-Infrared Fluorescence Imaging with Indocyanine Green: A Systematic Review of the Literature.

(1) Background: Near-infrared fluorescence imaging is a technique capable of assessing tissue perfusion and has been adopted in various fields including plastic surgery, vascular surgery, coronary arterial disease, and gastrointestinal surgery. While the usefulness of this technique has been broadly explored, there is a large variety in the calculation of perfusion parameters. In this systematic review, we aim to provide a detailed overview of current perfusion parameters, and determine the perfusion parameters with the most potential for application in near-infrared fluorescence imaging.

Efficacy of Sclerotherapy With Polidocanol (Ethoxysclerol) in Primary Aneurysmal Bone Cysts in Children and Adolescents.

Background: Aneurysmal bone cysts (ABC) are rare benign osseous lesions that can be locally aggressive. Traditionally, curettage with or without bone grafting is the treatment of choice. Recent data suggest that percutaneous sclerotherapy is a safe alternative to surgery.

Risk assessment in aortic aneurysm repair by medical specialists versus the American College of Surgeons National Surgical Quality Improvement Program risk calculator outcomes.

Objective: The aim of this online clinical vignette-based survey study was to compare risk assessments by vascular surgeons, anaesthesiologists and interventional radiologists involved in treating patients with aortic aneurysms in the Netherlands with the NSQIP risk calculator outcomes.

Methods: Participants, recruited using purposive sampling, provided their estimation of the likelihood of postoperative complications and events following aortic surgery in five fictional cases. These cases were subsequently scored using the NSQIP calculator.

Rupture of a Median Sacral Artery Aneurysm in a Patient with Vascular Ehlers Danlos Syndrome.

Introduction: Vascular Ehlers Danlos syndrome is a rare connective tissue disease that is associated with various arterial complications.

Report: A 25 year old man with vascular Ehlers Danlos syndrome presented with acute lower back pain as a result of a ruptured aneurysm of the median sacral artery (MSA). Prior medical history included several vascular events resulting in a right iliac occlusion.

Is Gorlin-Chaudhry-Moss syndrome associated with aortopathy?

Gorlin-Chaudhry-Moss syndrome (GCMS) is a rare disorder consisting of craniofacial dysostosis, hypertrichosis, underdeveloped genitalia, and ocular and dental anomalies. Recently, GCMS has been reclassified together with Fontaine syndrome as Fontaine progeroid syndrome (FPS), after a common genetic basis was found. It was previously thought that GCMS/FPS was not associated with aortopathy, but in recent years 3 patients with aortic disease have been described.

A novel technique to restore access in patients with central venous occlusion using the Surfacer Inside-Out Access Catheter System.

Exhausted central venous access is a potentially life-threatening situation for patients dependent on haemodialysis. If standard guidewire recanalisation fails, unconventional venous access or central venous needle recanalisation can be considered but are often associated with higher rates of complications and/or dysfunction. Here, we report about two patients treated successfully with the Surfacer Inside-Out Access Catheter System (Bluegrass Vascular Technologies, San Antonio, TX, USA) to achieve transmediastinal central venous access.

Introduction: Optimal management of soft tissue sarcoma (STS) remains a challenge. A nationwide survey assessed the quality of STS care in the Netherlands, thereby aiming to identify potentialities for improvement through more centralized disease management.

Methods: From the Netherlands Cancer Registry (NCR), data were obtained on 3317 adult STS patients (excluding gastrointestinal stromal tumor, GIST) diagnosed in 2006-2011.

Soft Tissue Tumors in Adults: ESSR-Approved Guidelines for Diagnostic Imaging.

Soft tissue sarcomas are rare, but early, accurate diagnosis with subsequent appropriate treatment is crucial for the clinical outcome. The ESSR guidelines are intended to help radiologists in their decision-making and support discussion among clinicians who deal with patients with suspected or proven soft tissue tumors. Potentially malignant lesions recognized by ultrasound should be referred for magnetic resonance imaging (MRI), which also serves as a preoperative local staging modality, with specific technical requirements and mandatory radiological report elements.
