BACKGROUND: Thoracic endovascular aortic repair (TEVAR) requires large-bore vascular access due to the considerable diameters of the endoprosthesis and delivery device. The preclose technique preceding endograft delivery has opened the door for an evolved access strategy. In addition, treatment under local anesthesia offers the advantage of optimal neuromonitoring. The goal of this study was to analyze the efficacy and safety of percutaneous TEVAR under local anesthesia. METHODS: All patients undergoing TEVAR in an elective setting at the Antwerp University Hospital between June 2012 and June 2015 were prospectively entered into an endovascular database...

Endovascular repair has a firmly established role in the treatment of aortic disease. The development of endovascular devices to treat even complex aortic disease has broadened the panorama of repair significantly but has also introduced new forms of repair failure. Standard devices for EVAR and TEVAR have also been enhanced, providing better adaptation to the anatomy treated, smaller delivery systems, more intuitive delivery designs as well as improved features to facilitate precise delivery of the device...

OBJECTIVES: To quantify the impact of thoracic endovascular aortic repair (TEVAR) on radial aortic strain with the aim of elucidating stent-graft-induced stiffening and complications. METHODS: Twenty fresh thoracic porcine aortas were connected to a mock circulatory loop driven by a centrifugal flow pump. A high-definition camera captured diameters at five different pressure levels (100, 120, 140, 160, and 180 mmHg), before and after TEVAR. Three oversizing groups were created: 0-9% (n = 7), 10-19% (n = 6), and 20-29% (n = 6)...

Left subclavian artery (LSA) revascularization is recommended during elective thoracic endovascular aortic aneurysm repair (TEVAR) when coverage is required for adequate proximal seal. Reported method for LSA revascularization includes open bypass, covered stent placement using chimney technique, and in situ laser fenestration. We reported a novel technique using percutaneous Outback reentry device for LSA revascularization in a 68-year-old male patient who underwent TEVAR for a 9-cm thoracic aortic aneurysm...

OBJECTIVES: Reference values of aortic deformation during the cardiac cycle can be valuable for the pre-operative planning of thoracic endovascular aortic repair (TEVAR) and for facilitating computational fluid dynamics. This study aimed to quantify normal aortic extensibility (longitudinal extension) and distensibility (radial expansion), as well as pulsatile strain, in a group of 10 (>60 years) individuals with abdominal or thoracic aortic aneurysms. METHODS: ECG gated CT images of the thoracic aorta were reconstructed into virtual 3D models of aortic geometry...

The patient described herein was a 75-year-old female. Echocardiography showed patent ductus arteriosus (PDA). Heart failure symptoms gradually appeared, and she was referred to our department for treatment. Contrast-enhanced computed tomography (CT) revealed a tubular structure communicating between the aortic arch and pulmonary artery trunk, suggesting adult PDA. Thoracic endovascular aortic repair (TEVAR) was performed to close PDA. Completion angiography confirmed the disappearance of PDA. Post-TEVAR CT revealed no endoleak...

Endovascular repair has become the treatment of choice for thoracic and abdominal aortic pathologies in the last decades, and is associated with excellent results in terms of perioperative, mid- and long-term morbidity and mortality. Access vessels play a central role in these procedures since access-related issues can increase the rates of technical failures and determine clinical complications for the patient. Therefore, accurate preoperative clinical evaluation and review of the preoperative images are mandatory...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) is the optimal therapy for complicated acute type B aortic dissection (aTBAD). This study examined clinical outcomes and aortic remodeling parameters after TEVAR for patients with complicated aTBAD. METHODS: From January 2012 to December 2015, 51 patients underwent TEVAR for complicated aTBAD. Preoperative and postoperative imaging studies were analyzed for sizes of the true lumen (TL) and false lumen (FL) and for the FL thrombosis status at five locations in the thoracic and abdominal aorta...

To observe the mid- and long-term result of intentional coverage of celiac artery in thoracic endovascular aortic repair (TEVAR) surgery for aortic dissection.
 Methods: We retrospectively analyzed 21 cases who received TEVAR with celiac artery coverage during the operation. The existence of collaterals between celiac artery (CA) and superior mesenteric artery (SMA) was confirmed by preoperative CT angiography (CTA) or digital substract angiography (DSA) for each patient. We used the stent-graft precisely above the orifice of SMA...

Living donor kidney transplantation (LDKT) is the optimal treatment for end-stage kidney disease (ESKD). The evaluation process for a kidney transplant is complex, time consuming, and burdensome to the ESKD patient. Also, race disparities exist in rates of transplant evaluation completion, transplantation, and LDKT. In December 2012 our transplant center implemented a streamlined, one-day evaluation process, dubbed Kidney Transplant Fast Track (KTFT). This paper describes the protocol of a two-part study to evaluate the effectiveness of KTFT at increasing transplant rates (compared to historical controls) and the TALK intervention (Talking About Live Kidney Donation) at increasing LDKT during KTFT...

Hospital mortality after the replacement of chronic type B aortic dissection is around 8-10% and adverse outcomes include paraplegia and stroke. However, the level of evidence for indication of thoracic endovascular aortic repair (TEVAR) for type B chronic aortic dissection is Class IIa. Results of the INSTEAD-XL trial have verified that preemptive TEVAR for uncomplicated type B aortic dissection improves prognosis. The indication for this procedure is reportedly a maximum aortic diameter >40 mm during the acute phase and a patent primary entry site in the thoracic aorta, while the optimal timing for TEVAR would be the subacute phase, from 2 weeks to 3-6 months after onset...

After Thoracic Endovascular Aortic Repair (TEVAR) for chronic type B aortic dissection (cTBD) the patency of the false lumen is quite common and its presence is associated with the risk of developing complications and is a predictor of death by aortic rupture. We report a case of a patient treated in emergency for the rupture of the false lumen in cTBD. He had previous TEVAR with persisting distal dissection and retrograde reperfusion of the false lumen. We performed an original endovascular treatment with graft relining and false lumen occlusion with a home-made "candy plug" obtained with two commercially available stent grafts...

Sonography has detected urate deposits in 34%-42% of the patients with asymptomatic hyperuricemia. This may prompt reclassification of asymptomatic hyperuricemia into "asymptomatic gout" and consideration of urate lowering therapy (ULT) to resolve urate deposits. In patients with gout and no visible tophi, sonography has detected urate deposits in half of the patients. This may allow diagnosing "tophaceous gout" and influencing the serum urate target level, prophylaxis to avoid acute gout flares during ULT, and clinical follow-up...

Several studies have suggested that surgical procedures performed at high-volume centers may result in superior outcome. Technically more demanding procedures such as aortic aneurysm repair appear to demonstrate a stronger relationship with volume. The present chapter reviewed the literature using the MEDLINE database to identify studies investigating the effect of volume in aortic aneurysm repair outcomes. The great majority of studies identified shows an advantage for high-volume hospitals with regard to perioperative mortality of abdominal (AAA), thoracic (TAA) and thoracoabdominal (TAAA) aortic aneurysm repair...

BACKGROUND: Closure of the proximal tear by thoracic endovascular aortic repair (TEVAR) at the acute phase appears to be a safe effective treatment to prevent aneurysmal degeneration type B dissection. However, it appears to be inefficient in up to a third of the patient. We report the technical aspects of our experience with patients undergoing secondary open repair after TEVAR for dissecting thoracoabdominal aneurysm despite early closure proximal tear by TEVAR. METHODS: During a period of 5 years, 96 patients presenting acute type B aortic dissections were treated by TEVAR and followed-up in our institution...
