OBJECTIVES: The objective of this study is to analyse the flow conditions in the AFX and Nellix endografts (EGs) accounting for their postimplantation configuration in patients with an endovascular aneurysm repair-treated abdominal aortic aneurysm. METHODS: We reconstructed post-endovascular aneurysm repair computed tomography scans of patients treated with an AFX or Nellix EG creating post-implantation EG models. We examined 16 patients, 8 in each group. The blood flow properties were obtained by computational fluid dynamics simulations and were subsequently compared with physiological infrarenal blood flow properties measured in 5 healthy subjects...

Aneurysmal disease involving the origins of supra aortic vessels often requires complex open and/or endovascular repair that is not only associated with significant risk of mortality and morbidity but also often with perioperative blood loss requiring transfusion. We report a successful repair of a large thoracic aortic aneurysm (TAA) involving the aortic arch with a custom-made Bolton Relay 2-vessel branched thoracic aortic endograft in a 42-year-old Jehovah's Witness who would otherwise be very unlikely to survive an open repair...

PURPOSE: To describe a modified up-and-over access technique for treatment of iliac artery aneurysms in patients with prior bifurcated stent-grafts for endovascular aneurysm repair (EVAR). TECHNIQUE: This technique uses a coaxial 12-F flexible sheath that is docked with a through-and-through wire into a 7-F sheath advanced from the contralateral femoral approach. This maneuver allows both sheaths to be moved as a unit while maintaining position of the apex of the system as it loops over the flow divider, avoiding damage to or displacing the extant endograft...

Thoracic aortic endograft implantation has become a widespread procedure in recent years, yet no report is available about Hungarian outcomes. Examination of our results is crucial to define further treatment strategies. Analysis of perioperative data from Hungarian thoracic endograft implantations based on the experience of 5 years is presented. Our retrospective, multicentric study analysed voluntarily reported data from all Hungarian institutions where thoracic endograft implantations are performed. Information was collected from every procedure performed in 5 years...

OBJECTIVES: Endovascular repair of aortic arch pathologies remains challenging. Recently, needle based in situ fenestration (ISF) has shown great potential in endovascular total aortic arch repair (ETAAR). This study aimed to evaluate the feasibility, effectiveness, and safety of ETAAR via needle based ISF, and to present initial experience with this technique. DESIGN AND METHODS: Patients who met the inclusion criteria were enrolled in this prospective study. The supra-arch branches were manually punctured in a retrograde manner using liver biopsy needles (18 gauge/30 cm) in the left common carotid artery (LCCA) and brachiocephalic trunk (BCT), and endo-puncture system or aspiration biopsy needles (21-gauge) in the left subclavian artery (LSA)...

OBJECTIVES: The aim of this study was to evaluate the diagnostic possibilities of accurately locating the entry site in acute retrograde Type A aortic dissection and the results of the corresponding endovascular treatments. METHODS: Among 100 patients who underwent surgery for the treatment of spontaneous acute Type A aortic dissection between 2012 and June 2017, all but 1 patient had preoperative computed tomographic angiography. A total of 8 retrograde extensions originated from the descending aorta, in which 6 of them were diagnosed correctly using radiological imaging...

The most common visceral revascularization technique during open repair of thoracoabdominal aortic aneurysms (TAAA) is the "inclusion technique," but its main long-term drawback is that the retained portion of the diseased aorta might be prone to further dilatation, thus giving rise to a recurrent visceral aortic patch aneurysm. This brief report presents 4 consecutive cases of visceral aortic patch aneurysms treated by means of fenestrated and branched endovascular approach with custom-made endografts. The procedures were technically successful in all 4 patients and no major complications were recorded at 11...

PURPOSE: To report the use of a branched iliac endograft to maintain internal iliac artery (IIA) patency in a patient with an infrarenal aortic aneurysm and short common iliac arteries (CIA). CASE REPORT: A 74-year-old man presented with an asymptomatic, fusiform, 67-mm infrarenal aortic aneurysm confirmed on computed tomography. The right CIA was funnel shaped and only 15 mm in length, providing no appropriate stent-graft landing zone. The left CIA measured 14 mm in diameter and 25 mm in length...

An 83-year-old man with aortic arch aneurysm underwent zone 0 thoracic endovascular aortic repair (TEVAR) by the chimney graft technique with two supra-aortic arch debranching grafts and developed subacute type A ascending aortic dissection. We performed emergency open conversion with circulatory arrest under deep hypothermia. The tip of the chimney graft (around the sino-tubular junction in the ascending aorta) was stiff, making it difficult to inspect the lumen and perform anastomosis. Deep hypothermic circulatory arrest and cutting the endograft stents to mobilize the graft were necessary for secure anastomosis...

Infectious complications of open and endovascular procedures for descending thoracic aortic disease are relatively rare, affecting 1% to 6% of treated patients. However, the number of thoracic aortic procedures, especially endovascular, is increasing continuously, and infectious complications involving the graft or endograft have been observed more frequently in recent years. Several causative factors may play a role in thoracic aortic prosthetic infections, including hematogenous seeding, local bacterial translocation, and iatrogenous contamination...

Although the incidence of abdominal and thoracic aortic endograft infection is infrequent, ranging between 0.2% and 5%, stent-graft infection carries significant morbidity and mortality and exemplifies a formidable therapeutic challenge. The treatment goal is to eradicate the infectious process by endograft explantation, regional tissue debridement, and arterial reconstruction by either an extra-anatomic or in situ grafting procedure using autologous vein, cryopreserved allograft, or antibiotic-soaked prosthetic grafts...

Due to the aging population, the number of patients treated with aortic grafts or endografts continues to increase. Although infection after these procedures is uncommon, aortic graft infection is a life-threatening condition, and refinement of management guidelines based on implant pathophysiology is appropriate. In the early 1990s, our European collaborative retrieval program, European Group for Research on Prostheses Applied for Vascular Surgery (GEPROVAS) was commissioned to analyze the degenerative phenomenon occurring on explanted grafts or endografts...

PURPOSE: To describe the application of uncovered chimney stent grafts with the Nellix endovascular aneurysm sealing technique (ChEVAS) for juxtarenal abdominal aortic aneurysms (JAAAs). CASE REPORT: Two patients with JAAA and multiple comorbidities were considered unfit for open surgery and were selected for an endovascular approach. Fenestrated and branched endografts were too expensive, and a chimney endovascular approach was considered inappropriate for the relatively high incidence of proximal type I endoleak and graft migration...

OBJECTIVE: Because of advances in technology and experience of the operator, endovascular aneurysm repair (EVAR) has supplanted open repair to treat abdominal aortic aneurysm (AAA). The low 30-day mortality and morbidity of EVAR make the endovascular approach particularly suitable for patients at high surgical risk. However, endoleak or endograft migration requiring secondary intervention or open surgical conversion is a limitation of EVAR. The Nellix system (Endologix, Inc, Irvine, Calif) has been designed to seal the entire AAA to overcome these limitations with EVAR...

PURPOSE: Thoracic endovascular aortic repair (TEVAR) is the preferred treatment of descending thoracic aorta pathology. However, TEVAR in the aortic arch remains challenging. Customized fenestrated TEVAR (fTEVAR) allows extension of the proximal seal zone, while preserving the involved supra-aortic vessels. There is a paucity of information on fTEVAR; hence, we aim to evaluate our early experience and lessons learnt with fTEVAR in the aortic arch. METHODS: This is a retrospective single-centre review of fTEVAR endografts for aortic arch pathology over 24 months...
