OBJECTIVES: The best surgical strategy for acute Stanford Type A aortic dissection (aTAAD) involving the arch remains controversial. Here, we report on the satisfactory results following aTAAD repair using a novel arch fenestrated stent graft. METHODS: From December 2014 to December 2015, 42 aTAAD patients (27 male and 15 female) underwent ascending aorta replacement and fenestrated stent graft implantation. The fenestrated stent graft was implanted into the true lumen of the aortic arch and proximal descending aorta, with the fenestration opening located at the ostia of 3 head vessels in the arch...

BACKGROUND: Stentless aortic valves have been developed to overcome obstructive limitations associated with stented bioprostheses. A new concept of surgical sutureless (SU) bioprosthesis has been developed in the last decade. In this multi-institutional study we sought to compare hemodynamics of different bioprosthesis concept as transcatheter (TAVR), Livanova Perceval S sutureless valve and Freedom Solo Stentless (FS) valve in patients undergoing aortic valve replacement (sAVR). METHODS: From 2010 to 2016, 478 patients underwent sAVR with FS, 518 Perceval S and 367 patients underwent TAVR...

BACKGROUND: Although reducing the incidence of unplanned readmission after thoracoabdominal aortic aneurysm (TAAA) repair represents an important opportunity to improve outcomes, predictors of readmissions are not known. We sought to characterize and identify factors associated with unplanned readmission after discharge in survivors of open TAAA repair. METHODS: Through prospective phone contact and retrospective record review, we determined the frequency and characteristics of unplanned readmissions within 30 days of discharge in 363 patients who were discharged after open TAAA repair...

BACKGROUND: Open surgical repair remains the "gold standard" treatment for chronic type B aortic dissection (cTBD) with aneurysm. Thoracic endovascular aortic repair (TEVAR) has gained popularity in recent years for the treatment of thoracic aortic diseases, including cTBD. We assessed the effectiveness of TEVAR in the treatment of cTBD using the Vascular Quality Initiative (VQI) database. METHODS: The VQI registry identified 4713 patients treated with TEVAR from July 2010 to November 2015, including 125 repairs for cTBD...

OBJECTIVES: Type 1a endoleak is one of the most severe complications after thoracic endovascular aortic repair (TEVAR), because it carries the risk of aortic rupture. The association between bird-beak configuration and Type 1a endoleak remains unclear. The purpose of this study was to analyse the predictors of Type 1a endoleak following Zone 1 and Zone 2 TEVAR, with a particular focus on the effect of bird-beak configuration. METHODS: From April 2008 to July 2015, 105 patients (mean age 68...

Endovascular fenestration on the abdominal aorta is effective for preventing visceral malperfusion in aortic dissection. We report a case of stented balloon fenestration before residual entry repair using the frozen elephant trunk technique for chronic aneurysmal dissection after ascending aortic replacement for DeBakey I aortic dissection. We recognized poor communication between the true lumen and false lumen in the abdominal aorta, and visceral perfusion depended almost entirely on the proximal large entry...

The reattachment of the supra-aortic vessels during hybrid arch repair using a branched prosthesis is time consuming and sometimes technically challenging. Here, we describe the surgical technique of bridging the end-to-end anastomoses between the graft branches and the supra-aortic vessels by self-expanding covered stents to reduce suturing time, avoid anastomotic bleeding, enhance true lumen remodeling, and improve vessel alignment to the hybrid graft.

A 72-year-old man previously treated for an abdominal aortic aneurysm (AAA) was diagnosed with the 70-mm-sized type IIIb aortic dissection. Endovascular repair was considered, but there was no stent graft passing through the 8-mm iliac graft that was used for open repair of the AAA. We sealed the 5-mm-sized intimal tear site, using an Amplatzer Vascular Plug, which successfully repaired. The patient was discharged and had no complications. Serial follow-up computerized tomography scans showed that the vascular plug was positioned without migration, and the size of the aorta decreased...

OBJECTIVE: A number of adjunctive "off-the-shelf" procedures have been described to treat complex aortic diseases. Our goal was to evaluate parallel stent graft configurations and to determine an optimal formula for these procedures. METHODS: This is a retrospective review of all patients at a single medical center treated with parallel stent grafts from January 2010 to September 2015. Outcomes were evaluated on the basis of parallel graft orientation, type, and main body device...

OBJECTIVE: We report our experience of the treatment of postdissection arch aneurysms and thoracoabdominal aortic aneurysms (TAAAs) by endovascular repair using fenestrated and branched endografts. METHODS: This study includes all patients presenting with chronic postdissection aneurysms >55 mm in diameter deemed unfit for open surgery and treated by complex endografting between October 2011 and April 2017. Where appropriate, staged management strategies including left subclavian artery revascularization, thoracic endografting, dissection flap fenestration, and tear enlargement were performed before the complex endovascular repair...

This case report is about an 85-year-old woman with bicuspid aortic stenosis (AS). Although preoperative multimodality imaging showed challenging anatomical aspects, transcatheter aortic valve replacement (TAVR) was selected to be performed as a less invasive alternative treatment approach, owing to her comorbidity. Postoperative transesophageal echocardiography and multidetector-row computed tomography revealed the presence of "locked-in leaflet" caused by stent distortion due to pinching by calcified native leaflets, with nodular calcification preventing the full expansion of the valve, which resulted in moderate perivalvular leakage...

Aortic aneurysms are life-threatening conditions with effective treatments mainly limited to emergency surgery or trans-arterial endovascular stent grafts, thus calling for the identification of specific molecular targets. Genetic studies have highlighted controversial roles of transforming growth factor β (TGF-β) signaling in aneurysm development. Here, we report on aneurysms developing in adult mice after smooth muscle cell (SMC)-specific inactivation of Smad4, an intracellular transducer of TGF-β. The results revealed that Smad4 inhibition activated interleukin-1β (IL-1β) in SMCs...

Herein, we report a rare case of type B aortic dissection that occurred after endovascular aortic aneurysm repair (EVAR). A 66-year-old man underwent successful EVAR for an abdominal aortic aneurysm (AAA). Computed tomography (CT) 2 years after EVAR showed a type B aortic dissection with stent-graft migration and AAA expansion. Juxtarenal aortic expansion precluded simple stent-graft placement. He underwent hepato-spleno-renal bypass followed by stent-graft placement just below the superior mesenteric artery...

Isolated abdominal aortic dissection (IAAD) is a rare form of aortic dissection involving usually the infrarenal part of the abdominal aorta. A 45-year-old male presented with lumbar pain and claudication. Computed tomography angiography (CTA) revealed an infrarenal IAAD extending to the left external iliac artery (EIA), causing ≥90% narrowing of the lumen. An endovascular approach was decided, with deployment of an aortic stent-graft and two balloon expandable stents in both common iliac arteries (IAs), applying the kissing stents technique...

OBJECTIVE: Isolated spontaneous dissection of the superior mesenteric artery (SMA) and celiac artery (CA) remains a rare condition; however, it has been increasingly noted incidentally on diagnostic imaging. The purpose of this study was to examine the natural history and outcomes of patients presenting with isolated spontaneous mesenteric artery dissection (SMAD). We hypothesized that most SMADs can be treated nonoperatively. METHODS: This was a single-center retrospective review of patients presenting with the diagnosis of SMAD between 2006 and 2016...

In patients with abdominal aortic aneurysms (AAA) and complete iliac occlusion, endovascular aortic aneurysm repair (EVAR) using a bifurcated stent graft has clear advantages over aortouniiliac stent grafts. Bifurcated stent grafts had improved hemodynamic flow and increased primary and secondary patency rates compared with aortouniiliac stent grafts. The use of aortouniiliac stent grafts with femorofemoral crossover bypass is associated with complications including infection of the prosthesis, steal phenomenon, and the associated difficulties for further endovascular access at the site of the femoral anastomosis...

Thoracic endovascular repair (TEVAR) has recently been established as the preferred treatment option for complicated type B dissection. This procedure involves covering the primary entry tear to stimulate aortic remodelling and promote false lumen thrombosis thereby restoring true lumen flow. However, complications associated with incomplete false lumen thrombosis, such as aortic dilatation and stent graft induced new entry tears, can arise after TEVAR. This study presents the application and validation of a recently developed mathematical model for patient-specific prediction of thrombus formation and growth under physiologically realistic flow conditions...

OBJECTIVES: The aim of this study was to investigate the accuracy of stent graft deployment in the distal landing zone (LZ) during thoracic endovascular aortic repair (TEVAR). Currently, TEVAR focuses on accurate stent graft deployment in the proximal LZ. Data on landing in the distal LZ are lacking. METHODS: Of 195 TEVAR patients (2005-16) with a non-dissected aortic pathology, 59 [median age 73 years (first quartile 68; third quartile 77), 20 women] patients had a distal LZ shorter than 40 mm...

Retrograde false-lumen flow after thoracic endovascular aortic repair of Type B aortic dissection occurs occasionally and may have a negative impact on aortic remodelling and even prevent the decompression of the false lumen. A 67-year-old man with a Type B aortic dissection underwent thoracic endovascular aortic repair for severe compression of the true lumen and visceral malperfusion 7 weeks after the onset. Intraoperative angiography revealed proximal entry tear closure, but the false-lumen flow increased because of retrograde flow through the re-entry tear...
