Purpose:To assess the significance of aortic remodeling in prevention late events after thoracic endovascular repair (TEVAR) for dissection. Methods:The study involved 52 patients (41 men; mean age was 59.7±13.3 years) with type B dissections and patent false lumens treated TEVAR between 2004 2011. Of patients, 18 were acute phase rupture (n=1), malperfusion (n=10), diameter over 40 mm at onset (n=3), rapid enlargement lumen (n=4). In chronic setting, indications (n=2), >50 (n=18), (n=13)....
Conventional total aortic arch repair is a high-risk procedure, particularly for patients. Although endovascular treatment of aneurysm recently induced only few cases are indicated and outcomes questionable. Here, we report on the early short-term results our surgical i.e. hybrid with supra-aortic debranching endografting into ascending aorta.Of 514 patients who underwent repairs from 1997 to March 2012, 40 (28 males; mean age 74.4 years) were whom landing zone was performed. Aortic...
Type 1a endoleak is one of the most severe complications after thoracic endovascular aortic repair (TEVAR), because it carries risk rupture. The association between bird-beak configuration and remains unclear. purpose this study was to analyse predictors following Zone 1 2 TEVAR, with a particular focus on effect configuration.From April 2008 July 2015, 105 patients (mean age 68.6 years) who underwent landing TEVAR were enrolled, mean follow-up period 4.3 years. categorized into groups,...
In recent years, supra-aortic rerouting and thoracic endovascular aortic repair (TEVAR) for treating arch pathology have emerged as a less invasive option high-risk patients. This study aimed to assess our strategy preventing stroke improving late outcomes after TEVAR. Between July 2008 2015, we performed 280 cases of TEVAR pathologies, using manufactured stent grafts. reviewed 101 patients who underwent degenerative distal aneurysms (80 men, mean age 73.1 Zone 1/Zone 2 = 48/53). Since 2011,...
The objective of this study was to evaluate the effectiveness embolic protection filter device in stroke prevention during hybrid endovascular arch repair patients with significant aortic atheroma.Twenty-two (20 men, mean age 79.0 years, logistic EuroSCORE 23.9%) arch/proximal descending diseases and atheroma (atheroma grade ≥ II) who were deemed unfit for conventional open surgery underwent supra-arch vessels using a balloon catheter devices. preventing evaluated by postoperative...
Zone 0 landing in thoracic endovascular aortic repair (TEVAR) has recently gained increasing attention for the treatment of high-risk patients. The aim this study was to compare outcomes total arch between branched TEVAR (bTEVAR) and chimney (cTEVAR) zone (LZ) 0.This a single-center, retrospective, observational cohort study. From January 2010 March 2020, 40 patients (bTEVAR, n=25; cTEVAR, n=15; median age: 79 years) were enrolled study, with follow-up period 4.1 years. These considered...
Stent grafting for complex aortic anatomy remains a challenge. In particular, stent graft collapse (i.e. infolding) is possible when an excessive oversized device needed. We describe case of preoperative simulation using three-dimensional (3D) printed model extensive arch repair in 69-year-old woman with multiple aneurysms combined coarctation. The patient was scheduled to undergo staged hybrid repair. A larger than 28 mm diameter needed deploy into coarctation 15 during the 2nd stage...
Silent cerebral infarction is the most common brain injury incidentally detected on imaging and can be associated with increased risks of future stroke cognitive decline. However, incidence risk factors silent after thoracic endovascular aortic repair (TEVAR) for arch pathologies remain unclear. This study aimed to examine following TEVAR using diffusion-weighted (DW) magnetic resonance (MRI).Nineteen patients (16 men, mean age 73.3 years) who underwent elective debranching (zone 0/1/2 =...
The repair of extensive thoraco-abdominal aortic aneurysms (TAAAs) is invasive and carries a high risk for spinal cord injury (SCI). aim this study was to assess the early results collateral circulation after hybrid Crawford extent II aneurysms.Between 1997 2013, we performed 128 thoracic endovascular (TEVAR) procedures TAAAs. This reviews 12 patients who underwent TEVAR aneurysm (mean age: 56 years, 6 men, chronic dissection: 10). Aortic arch create proximal landing zone visceral...
Abstract OBJECTIVES To evaluate the impact of coronavirus disease 2019 (COVID-19) pandemic on acute and elective thoracic abdominal aortic procedures. METHODS Forty departments shared their data procedures between January May 2020 in Europe, Asia USA. Admission rates as well delay from onset symptoms to referral were compared. RESULTS No differences number observed reference period [incidence ratio (IRR): 0.96, confidence interval (CI) 0.89–1.04; P = 0.39]. Also, no difference time was...
Resection of a primary entry tear is essential for the treatment Stanford type A acute aortic dissection (AAAD). In DeBakey III retrograde AAAD (DBIII-RAAAD), resection in descending aorta sometimes difficult. The frozen elephant trunk technique and thoracic endovascular repair (TEVAR) enable closure aorta. aim this study was to investigate efficacy or entry, i.e. exclusion, patients with retrograde-AAAD.
Stent graft-induced distal re-dissection (SIDR) is a burdensome complication after thoracic endovascular aortic repair (TEVAR) for Type B dissection. We developed novel method to prevent SIDR by placing small-diameter short stent graft [Excluder Aortic Extender (Cuff)] at the landing zone (DLZ) and reviewed its effectiveness in this study.Ninety patients who underwent TEVAR dissection using commercially available devices between January 2008 September 2016 were retrospectively reviewed....
Objective: This study aims to determine how instructions for use affect the occurrence of aneurysm sac growth and endoleaks after an endovascular repair (EVAR).
Aortic graft infection (AGI) is a serious condition associated with high mortality rate. However, optimal surgical options have not been identified. Therefore, we retrospectively reviewed AGI cases, including those in the thoracic and abdominal regions, or without fistula formation, to investigate various for better outcomes.We 50 patients who underwent interventions out of 97 arterial infective disease. The mean patient age was 67 ± 17 years. Fourteen (28%) had gastrointestinal tract lung....
Optimal methods to quantitatively evaluate the blood flow in each cerebral artery after zone 1-2 thoracic endovascular aortic repair (TEVAR) remain unknown. Our objective was differences between preoperative and postoperative flows debranching TEVAR (dTEVAR).Between January 2016 August 2018, a prospective analysis of both internal carotid vertebral 16 patients before dTEVAR conducted. Zone 1 with right axillary artery-left common (RAxA-LCCA-LAxA) bypass performed on 7 patients. 2 9 patients:...
We describe the successful treatment of a patient with extended-aortic prosthetic graft infection (PGI) by surgery limited to infected lesion based on 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) findings.A 54-year-old man, who had undergone three replacements (GRs) for extended-thoracic aortic aneurysms, was diagnosed PGI complicated an aorto-esophageal fistula. On basis 18F-FDG PET/CT findings, we performed redo total arch replacement, preserving...
Abstract OBJECTIVES The risk of spinal cord injury after thoraco-abdominal aortic aneurysm repair increases when the segmental arteries (SAs) in critical segment are sacrificed. Such SAs cannot be reconstructed performing thoracic endovascular (TEVAR). We aimed to elucidate extrathoracic collaterals (T9–L1) that develop TEVAR. METHODS Between 2006 and 2018, 38 patients were sacrificed during Nineteen these who underwent multidetector row computed tomography 6 months surgery included (mean...
A 72-year-old man underwent sutureless repair of an oozing-type left ventricular free wall rupture. Echocardiography 8 months after revealed a huge pseudoaneurysm and severe mitral regurgitation (MR). Therefore, reconstruction restrictive annuloplasty were performed. The patient's clinical condition was improved no residual MR has been detected for 12 months. We conclude that could be useful with MR.
