Focal Aortic Dissection With Significant Stenosis: A Rare Long Term Complication After TEVAR for Blunt Traumatic Aortic Injury in an Adolescent Patient.

Background: Thoracic endovascular aortic repair (TEVAR) in children and adolescents after blunt traumatic aortic injury (BTAI) is being performed increasingly despite no endovascular graft being approved for TEVAR in this population. The smaller diameter of the aorta and access vessels and steeper angle of the aortic arch pose specific challenges for TEVAR in this population. Moreover, data are lacking regarding medium to long term complications.

Identifying Patients at High Risk for Post-EVAR Aneurysm Sac Growth.

Purpose: Post-EVAR (endovascular aneurysm repair) aneurysm sac growth can be seen as therapy failure as it is a risk factor for post-EVAR aneurysm rupture. This study sought to identify preoperative patient predictors for developing post-EVAR aneurysm sac growth.

Material And Methods: A systematic review was conducted to select potential predictive preoperative factors for post-EVAR sac growth (including a total of 34.

Administrative healthcare data as an addition to the Dutch surgical aneurysm audit to evaluate mid-term reinterventions following abdominal aortic aneurysm repair: A pilot study.

Background: The Dutch Surgical Aneurysm Audit (DSAA) is a nationwide mandatory quality registry that evaluates the perioperative outcomes of abdominal aortic aneurysms (AAAs). The DSAA includes perioperative outcomes that occur up to 30 days, but various complications following AAA repair occur after this period. Administrative healthcare data yield the possibility to evaluate later occuring outcomes such as reinterventions, without increasing the registration burden.

Nationwide Outcomes of Octogenarians Following Open or Endovascular Management After Ruptured Abdominal Aortic Aneurysms.

Purpose: Octogenarians are known to have less-favorable outcomes following ruptured abdominal aortic aneurysm (rAAA) repair compared with their younger counterparts. Accurate information regarding perioperative outcomes following rAAA-repair is important to evaluate current treatment practice. The aim of this study was to evaluate perioperative outcomes of octogenarians and to identify factors associated with mortality and major complications after open surgical repair (OSR) or endovascular aneurysm repair (EVAR) of a rAAA using nationwide, real-world, contemporary data.

Treatment Outcome Trends for Non-Ruptured Abdominal Aortic Aneurysms: A Nationwide Prospective Cohort Study.

Objectives: Low profile endovascular aneurysm repair (EVAR) devices such as the Cordis INCRAFT AAA Stent Graft System may expand the category of patients suitable for endovascular repair. We report our experience with the INCRAFT system in treating ruptured abdominal aortic aneurysms (rAAA).

Methods: We included all patients presenting with rAAA from 2015 to 2019 in our hospital who were treated by percutaneous EVAR with the INCRAFT system.

Clinical Relevance of Closed-Incision Negative Pressure Therapy (ciNPT) for SSI-Risk Reduction in Vascular Surgery Through a Groin Incision.

Background: Vascular surgery, especially lower limb revascularization surgery, has one of the highest rates of surgical complications, predominantly surgical site infections (SSI). Resulting in a significant burden of additional costs due to longer hospital stays, re-admissions and re-interventions, mainly attributable to deep incisional SSIs. Closed incisional negative pressure therapy (ciNPT) is a relatively new strategy in the postoperative management surgical wounds, aiming to reduce surgical wound complications.

Wall Shear Stress Assessment of the False Lumen in Acute Type B Aortic Dissection Visualized by 4-Dimensional Flow Magnetic Resonance Imaging: An Ex-Vivo Study.

Background: Four-dimensional flow magnetic resonance imaging (4D flow MRI) can accurately visualize and quantify flow and provide hemodynamic information such as wall shear stress (WSS). This imaging technique can be used to obtain more insight in the hemodynamic changes during cardiac cycle in the true and false lumen of uncomplicated acute Type B Aortic Dissection (TBAD). Gaining more insight of these forces in the false lumen in uncomplicated TBAD during optimal medical treatment, might result in prediction of adverse outcomes.

Outcomes in Octogenarians and the Effect of Comorbidities After Intact Abdominal Aortic Aneurysm Repair in the Netherlands: A Nationwide Cohort Study.

Objective: Age is an independent risk factor for mortality after both elective open surgical repair (OSR) and endovascular aneurysm repair (EVAR). As a result of an ageing population, and the less invasive nature of EVAR, the number of patients over 80 years (octogenarians) being treated is increasing. The mortality and morbidity following aneurysm surgery are increased for octogenarians.

Nationwide Study to Predict Colonic Ischemia after Abdominal Aortic Aneurysm Repair in The Netherlands.

Background: Colonic ischemia remains a severe complication after abdominal aortic aneurysm (AAA) repair and is associated with a high mortality. With open repair being one of the main risk factors of colonic ischemia, deciding between endovascular or open aneurysm repair should be based on tailor-made medicine. This study aims to identify high-risk patients of colonic ischemia, a risk that can be taken into account while deciding on AAA treatment strategy.

Long-term Follow-up of a Randomized Clinical Trial Comparing Endovascular Revascularization Plus Supervised Exercise With Supervised Exercise Only for Intermittent Claudication.

Objective: The goal of this study was to assess the long-term effectiveness of combination therapy for intermittent claudication, compared with supervised exercise only.

Background: Supervised exercise therapy is recommended as first-line treatment for intermittent claudication by recent guidelines. Combining endovascular revascularization plus supervised exercise shows promising results; however, there is a lack of long-term follow-up.

10-Year Paclitaxel Dose-Related Outcomes of Drug-Eluting Stents Treated Below the Knee in Patients with Chronic Limb-Threatening Ischemia (The PADI Trial).

Purpose: Recently, two meta-analyses concluded that there appears to be an increased risk of long-term mortality of paclitaxel-coated balloons and stents in the superficial femoral and popliteal artery, and paclitaxel-coated balloons below the knee. In this post hoc study of the PADI Trial, we investigated the long-term safety of first-generation paclitaxel-coated drug-eluting stents (DES) below the knee and the dose-mortality relationships of paclitaxel in patients with chronic limb-threatening ischemia (CLI).

Materials And Methods: The PADI Trial compared paclitaxel-coated DES with percutaneous transluminal angioplasty with bail-out bare-metal stents (PTA ± BMS) in patients with CLI treated below the knee.

The Influence of Aortic Wall Elasticity on the False Lumen in Aortic Dissection: An In Vitro Study.

Background: Hemodynamics, dissection morphology, and aortic wall elasticity have a major influence on the pressure in the false lumen. In contrast to aortic wall elasticity, the influence of hemodynamics and dissection morphology have been investigated often in multiple in vitro and ex vivo studies. The purpose of this study was to evaluate the influence of aortic wall elasticity on the diameter and pressure of the false lumen in aortic dissection.
