Incidence and risk factors for incisional hernia after open abdominal aortic aneurysm repair.

Introduction: Incisional hernia (IH) is common after open abdominal aortic aneurysm (AAA) repair. Recent studies reported incidence rates higher than previously stated. The aim of this study was to quantify the IH incidence after open AAA surgery.

Systematic Review on the Use of Physician-Modified Endografts for the Treatment of Aortic Arch Diseases.

Background: The total endovascular approach is in current evolution, and many series have described variable outcomes for branched technology, chimney techniques, or fenestrated repair; and even a combination of some of them. We aim to describe the current outcomes on physician-modified endograft for the treatment of arch diseases.

Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used for this systematic review.

Pelvic radiation therapy as a potential risk factor for ischemic colitis complicating abdominal aortic reconstruction.

A 78-year-old man with a 56-mm juxtarenal aneurysm and previous pelvic radiotherapy for prostate cancer (3 years earlier) who was disease free during follow-up received elective aortoaortic bypass suprarenal clamping through a transperitoneal approach. After the patient experienced initial abdominal pain and diarrhea, a computed tomography scan showed mild sigmoid inflammation, and the patient received conservative treatment. One month after discharge, the patient underwent urgent laparotomy and bowel and sigmoid resection for an enterocutaneous fistula.

The Potential Relation Between polytetrafluoroethylene Grafts after Open Reconstructions for Abdominal Aortic Aneurysm and Perigraft Seromas.

Background: The presence of sac enlargement after abdominal aortic aneurysm (AAA) open repair, a condition usually called perigraft seroma (PGS), nearly always has a benign behavior. Some theories implicated for PGS formation include coagulation abnormalities, fibroblast inhibition, low-grade infection, or improper graft handling.

Methods: This is a retrospective study including patients treated for AAA in 2 academic vascular surgery departments from 2007 to 2014, where 1 center preferably used polytetrafluoroethylene (PTFE) grafts whereas the preference of other center was mostly Dacron graft.

Predictors of inadequate EndoAnchors aortic wall penetration for the Endosutured therapy in hostile neck patients.

Background: The use of EndoAnchors is increasing; however, not much about appropriate use in terms of aortic wall penetration (AWP) is described. We aim to evaluate the procedural and anatomical conditions related with borderline (b) or absence (ab) of AWP when checked on first CT-scan after the Endosutured aortic repair (ESAR) for hostile neck anatomies (HNA).

Methods: This study with NCT04100499 is a single center prospective evaluation of patients receiving EndoAnchors for prevention or treatment of a proximal EVAR failure.

Adapting Vascular Surgery Practice to the Current COVID-19 Era at a Tertiary Academic Center in Madrid.

Background: The epidemic potential of coronavirus infection is now a reality. Since the first case detected in late 2019 in China, a fast worldwide expansion confirms it. The vascular patient is at a higher risk of developing a severe form of the disease because of its nature associating several comorbid states, and thus, some vascular surgery communities from many countries have tried to stratify patients into those requiring care during these uncertain times.

Partial Renal Coverage after Endovascular Aortic Aneurysm Repair with Suprarenal Fixation Seems Not to be Associated with Early Renal Impairment.

Background: Efforts to achieve optimal seal during endovascular aortic aneurysm repair (EVAR) may produce partial coverage of the lowest renal artery and in some cases even occlusion. This coverage might alter the renal ostial flow, which could finally affect renal function. We sought to evaluate the incidence of renal ostium coverage and its possible effects on renal function.

Impact of the Aortic Graft on Arterial Stiffness and Inflammatory Biomarkers after Endovascular Aortic Repair or Open Surgical Repair in Abdominal Aortic Aneurysm Disease.

Background: Abdominal aortic aneurysm (AAA) is an important cardiovascular (CV)-related disease that requires surgical treatment to prevent rupture. The elevation of arterial stiffness (AS) is an increasingly recognized independent determinant of CV morbidity and mortality and plays a special role in atherosclerosis. The importance of the surgical technique used for AAA repair in the long-term outcomes still needs to be clarified, and whether endovascular aortic repair (EVAR) or open surgical repair (OSR) confers high AS measurements and thus worse prognosis in terms of CV morbidity needs further investigation.

Symptomatic Aortic Bare-Metal Stent Fracture after PETTICOAT Technique for Complicated Type B Aortic Dissection.

Background: Aortic bare-metal stent rupture is an exceptional complication, associated with high risk of aorta rupture and death. We describe a successful endovascular approach for a symptomatic aortic bare-metal stent fracture after the provisional extension to induce complete attachment (PETTICOAT) technique.

Methods: A 53-year-old man with a complicated type B aortic dissection (visceral malperfusion) was treated with thoracic endovascular aortic repair (TEVAR) and "PETTICOAT" technique.

Expanded Suitability of Ruptured Abdominal Aortic Aneurysms for Total Endovascular Repair Using the Endurant Endograft and Heli-FX EndoAnchors.

Purpose: To assess if the suitability of endovascular aneurysm repair (EVAR) of ruptured abdominal aortic aneurysms (RAAAs) can be expanded by combining the Endurant stent-graft with the Heli-FX EndoAnchors.

Materials And Methods: Contrast-enhanced computed tomography (CT) scans of 90 patients (mean age 73.2±9 years; 87 men) with RAAA admitted between January 2014 and January 2018 in 2 tertiary care centers were analyzed in a 3-dimensional workstation.

Descending Aorta Rupture after Transcatheter Aortic Valve Embolization.

Background: To report a case of rupture of the descending aorta after aortic migration during transcatheter aortic valve replacement (TAVR).

Methods: An 85-year-old man with a severe and symptomatic aortic stenosis underwent elective TAVR, which complicated with embolization into the ascending aorta. While repositioning into the descending aorta, the procedure complicated with aortic rupture.

The Cuff Plus Anchoring Funnel Technique for Endovascular Aortic Repair (CAF-EVAR) for Large Infrarenal Necks.

Purpose: To present a case of a patient with possible short (2 years approximately) life expectancy and a 68-mm abdominal aortic aneurysm with a large infrarenal neck and large suprarenal aorta that precluded chimney endovascular aortic repair (Ch-EVAR) treatment.

Materials And Methods: The technical aspects of a modification of the funnel technique (thoracic endograft as a proximal extension of a main infrarenal device in wide necks) are described. We advocated a migrated bifurcated 36-mm endograft in a 34-mm native aorta, ten mm below the lowest renal artery and added endoanchor (four) fixation to this "intentionally migrated main endograft.

Failed Minimally Invasive Staged Treatment of a Giant Symptomatic Aortic Perigraft Hygroma after Open Aortic Repair.

Background: Perigraft hygromas or seromas are an unusual finding and/or complication after open aortic repair.

Methods And Results: We present a case of an 82-year-old man with a previous urgent aortic bifurcated graft for abdominal aortic aneurysm rupture. He received several treatments due to abdominal compartment syndrome, requiring a Bogota Bag and colostomy derivation.

A Word of Caution for Extra Large Self-expandable Nitinol Stents.

Background: To report an unsuccessful use of large nitinol stent to prevent proximal endoleak in endograft treatment for juxtarenal aortic aneurysm.

Case Report: An 82-year-old male presented coronary disease and severe chronic obstructive pulmonary disease requiring oxygen support. A large 80-mm juxtarenal aneurysm was found on routine urological examination.

Treatment of aberrant right subclavian artery aneurysm with endovascular exclusion and adjunctive surgical bypass.

Aberrant right subclavian arteries occur in as much as 2% of the population. Aneurysms in this vessel are rare but exhibit a marked propensity toward rupture; therefore, early elective treatment is indicated. Transluminally placed stent-grafts offer an alternative approach to the standard surgical treatment.
