Chronic aortic dissecting aneurysms (TAAD) presenting after acute Stanford Type A or B dissection includes both arch and/or thoracoabdominal aortic aneurysms (TAAA). Approximately 60% of patients who survive surgical treatment of acute Type A aortic dissections will require another aortic procedure. Similarly, more than 70% of patients with chronic Type B aortic dissections will experience false lumen dilation at 5-year follow-up, often requiring intervention. Open or hybrid aortic repairs of complex TAAD involving the arch and the TAAA are very demanding procedures for both patients and clinicians...

PURPOSE: To investigate the initial proximal position and seal of the Nellix EndoVascular Aneurysm Sealing (EVAS) system in the aortic neck using a novel methodology. METHODS: Forty-six consecutive patients who underwent elective EVAS for an abdominal aortic aneurysm were retrospectively selected and dichotomized into an early (n = 23) and a late (n = 23) group. The aortic neck morphology and aortic neck surface (ANS) were determined on preoperative computed tomography (CT) scans; the endograft position and nonapposition surface (NAS) were determined on the 1-month CT scans...

BACKGROUND: Circulatory collapse is a leading cause of mortality among traumatic major exsanguination and in ruptured aortic aneurysm patients. Approximately 40% of patients die before hemorrhage control is achieved. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an adjunct designed to sustain the circulation until definitive surgical or endovascular repair. A systematic review was conducted for the current clinical use of REBOA in patients with hemodynamic instability and to discuss its potential role in improving prehospital and in-hospital outcome...

OBJECTIVE: Proximal neck dilation is a serious long-term complication directly causing the failure of endovascular aneurysm repair (EVAR) and open surgical repair (OSR) of abdominal aortic aneurysms. However, the implantation of a fenestrated device presents the opportunity for proximal extension of the aortic reconstruction into a healthy segment while maintaining patency of the visceral vessels. The objective of this investigation was to report perioperative and follow-up outcomes using the Zenith Fenestrated (ZFEN; Cook Medical, Bloomington, Ind) aortic stent system in salvaging previous aortic repairs undergoing type IA endoleak or aneurysmal degeneration of the proximal neck...

OBJECTIVE: Open aortic repair (OAR) is associated with higher risk of mortality compared with endovascular aneurysm repair (EVAR). The aim of this study was to compare failure to rescue (FTR) after major predischarge complications in patients undergoing OAR and EVAR. METHODS: Patients who underwent OAR or EVAR in the American College of Surgeons National Surgical Quality Improvement Program between 2011 and 2015 were selected. Patients with ruptured aneurysm and those with type IV thoracoabdominal aneurysms were excluded...

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) is the standard treatment of blunt thoracic aortic injury (BTAI). The concept of seal was derived from the treatment of aneurysms and has been adopted for BTAI. Given the location of injury in BTAI, left subclavian artery (LSA) coverage is sometimes necessary. In these often healthier aortas, a shorter proximal landing zone may be acceptable and beneficial in avoiding some complications. Current practice patterns vary, and long-term effects of LSA coverage remain unknown...

Background: There is a potential for direct model manufacturing of abdominal aortic aneurysm (AAA) using 3D printing technique for generating flexible semi-transparent prototypes. A patient-specific AAA model was manufactured using fused deposition modelling (FDM) 3D printing technology. A flexible, semi-transparent thermoplastic polyurethane (TPU), called Cheetah Water (produced by Ninjatek, USA), was used as the flexible, transparent material for model manufacture with a hydrophilic support structure 3D printed with polyvinyl alcohol (PVA)...

BACKGROUND: In Marfan syndrome early impairment of left ventricular systolic function has been reported. Our aim was to evaluate the left ventricular systolic function in young adults with Marfanoid habitus (MH) (includes arachnodactylia, dolichostenomelia, high palate, deformations of the thorax). METHODS: We studied 137 young subjects (mean age 21.3±1.5) - 58 male, 79 female. Transthoracic echocardiography (Vivid 7 Dimension, GE) was performed in 24 asymptomatic MH with excluded Marfan syndrome and 42 healthy control subjects...

We present here a case of successful staged treatment of a patient with para-aortic abscess that arose 5 years after thoracic endovascular aortic repair because of thoracic aortic aneurysm. After stabilization of the patient's condition by intensive antibiotic therapy we performed left-subclavian extra-thoracic debranching as the first stage of the surgical treatment. In 2 weeks via median sternotomy and on-pump we removed the infected endograft and performed extraanatomical ascending-to-descending aortic bypass with good postoperative result...

BACKGROUND: In patients undergoing open surgery for a ruptured abdominal aortic aneurysm (rAAA), survivors demonstrate a high platelet count, and proactive administration of platelets (and fresh frozen plasma) appears to influence mortality. OBJECTIVES: This trial investigated the effect of platelets administered before transport to surgery. METHODS: In a prospective study design, patients were randomised to receive platelets (intervention; n = 61) or no platelets (control; n = 61) before transport to vascular surgery from 11 local hospitals...

Introduction: Hybrid aortic arch repair for the treatment of aorto-bronchial fistulas has been suggested as a safe alternative to open repair. However, surgical morbidity and mortality are still significant and re-intervention is sometimes inevitable. Report: Successful rescue by a hybrid approach is reported in a 76 year old woman who was transferred from another centre with recurrent episodes of left hemiplegia shortly after debranching of the supra-aortic vessels and thoracic aortic stent grafting for an aorto-bronchial fistula associated with a true aneurysm at the level of origin of the left subclavian artery...

Introduction: Although thoracic endovascular aortic repair (TEVAR) has become a promising treatment for complicated acute type B dissection, its role in treating chronic post-dissection thoraco-abdominal aortic aneurysm (TAA) is still limited owing to persistent retrograde flow into the false lumen (FL) through abdominal or iliac re-entry tears. Report: A case of chronic post-dissection TAA treatment, in which a dilated descending FL ruptured into the left thorax, is described...

Aortic coarctation is one of the most common congenital cardiac pathologies. Repair of native aortic coarctation is nowadays a common and safe procedure. However, late complications, including re-coarctation and aneurysm formation, are not uncommon. The incidence of these complications is dependent on the type of the initial operation. Both endovascular and conventional open repair play important roles in the treatment of late complications after previous coarctation repair. This article will review the incidence of late complications after coarctation repair and will discuss the treatment options for redo coarctation repair in adult patients...

Genetic discovery for heritable thoracic aortic disease (HTAD) has been progressing at a brisk pace. Surgical management of thoracic aortic aneurysms and dissections has become more personalized, with genetic factors increasingly informing the decision of when to operate on patients. An improved understanding of genotype-phenotype correlations in patients with HTAD will ultimately lead to gene- and mutation-specific recommendations for surgical repair. Until more robust data from larger cohorts can inform our decisions, patients with HTAD should be seen by an aortic specialist for a tailored approach to elective surgical repair...

Introduction: Iodinated contrast media completion angiography (ICM-A) may underestimate the presence of type II endoleak (ELII) after endovascular aortic repair (EVAR), particularly if they are at low flow. Contrast-enhanced ultrasound (CEUS) has been proposed as the gold standard in ELII detection during EVAR follow-up. Intraprocedural carbon dioxide (CO2 ) angiography has been shown to be useful in this setting; however no comparative studies including these three techniques are currently available...

OBJECTIVE: Patient-based decision aids and other multimedia tools have been developed to help enrich the preoperative discussion between surgeon and patient. Use of these tools, however, can be time-consuming and logistically challenging. We investigated whether simply showing patients their images from preoperative computed tomography (CT) or angiography would improve patients' satisfaction with the preoperative discussion. We also examined whether this improved the patient's understanding and trust and whether it contributed to increased preoperative anxiety...
