PURPOSE: To evaluate the applicability of an off-the-shelf scalloped stent-graft to preserve left subclavian artery (LSA) flow in thoracic endovascular aortic repair (TEVAR) for acute type B aortic dissection. METHODS: The computed tomography angiograms (CTA) of 70 consecutive patients (median age 64 years; 44 men) with acute Stanford type B aortic dissection were retrospectively analyzed to identify patients in whom a short proximal landing zone (<15 mm from the retrogradely dissected wall layers) would require LSA overstenting during TEVAR...

PURPOSE: To describe an innovative endovascular technique that successfully reconstructs a renal artery completely perfused by the false lumen after thoracic endovascular aortic repair (TEVAR). CASE REPORT: A 65-year-old patient diagnosed with acute Stanford type B aortic dissection underwent successful TEVAR 4 years ago. Regular follow-up found that the thoracic aorta was well repaired, but the false lumen in the abdominal aorta had enlarged year by year. The left renal artery was supplied entirely by the false lumen, which caused kidney hypoperfusion...

BACKGROUND: Currently, optimal medical therapy is first-line therapy for uncomplicated acute type B aortic dissection (aTBAD) despite poor long-term outcomes. This study examines the impact of thoracic endovascular aortic repair (TEVAR) in the acute and chronic phases on short-term and long-term survival of patients presenting with aTBAD. METHODS: A review of the Emory aortic database from 2000 to 2016 identified 398 patients diagnosed with aTBAD. At index hospitalization, complicated patients underwent TEVAR (aTEVAR [thoracic endovascular aortic repair in the acute phase], n = 80) and uncomplicated patients received optimal medical therapy (n = 318)...

OBJECTIVES: Actin, alpha-2, smooth muscle, aorta (ACTA2) mutations are one of the major causes of familial thoracic aortic aneurysms and dissections. The aim of this study was to review our clinical results of young adult patients with aortic disease caused by ACTA2 mutations. METHODS: We reviewed the medical records of 251 patients (<50 years old) who underwent surgery for thoracic aortic diseases between 2004 and 2014. Among them, nine patients (3.5%) had ACTA2 mutations...

OBJECTIVES: The prognosis of patients with intramural haematoma (IMH) of the aorta beyond the first year after diagnosis remains largely unknown. In particular, patients that do not undergo interventions are lost to follow-up. The aim was to assess medium-term outcome in IMH patients. METHODS: Post hoc analysis of 63 consecutive patients presenting with IMH between 1999 and 2013 was performed. Patients meeting imaging criteria at the first presentation were included even if follow-up imaging showed evidence of intimal disruption or false lumen flow...

PURPOSE OF REVIEW: Intramural hematoma (IMH) is one of the acute aortic syndromes. IMH was originally noted as an 'aortic dissection without intimal tear.' It had been speculated that IMHs were caused by ruptured vasa vasorum in the aortic media and distinguished from classical aortic dissections. However, the majority of IMHs are now detected with an intimal defect using high-resolution computed tomography, which implies that IMHs may be a subset of aortic dissections with very limited flow in the false lumen...

BACKGROUND AND AIM: Concomitant endovascular stent grafting of the descending thoracic aorta during open repair for acute DeBakey I aortic dissection can be performed in patients with extensive dissection and malperfusion. We analyzed the effects of this strategy on distal aortic remodeling. METHODS: From 2006-2014, acute DeBakey I dissection patients without primary aortic arch tear undergoing open distal hemiarch reconstruction (Standard group) versus those undergoing hemiarch with descending thoracic aorta (DTA) thoracic endovascular aortic repair (TEVAR group) were retrospectively reviewed...

Herein, we report the case of a 60-year-old man, a smoker with a history of arterial hypertension and diabetes mellitus. After computed tomography (CT) for an episode of hemoptysis, the patient underwent elective thoracic endovascular aortic repair (TEVAR) because of a degenerative aneurysm of the descending thoracic aorta. The area of perianeurysmal pulmonary atelectasis reported on the CT scan was not considered. Three months later, he developed an aortopulmonary fistula without endoleaks. Although TEVAR is a relatively safe procedure, no detail should be overlooked in the preoperative evaluation in order to avoid life-threatening complications...

Aorto-esophageal fistula (AEF) is a rare and lethal entity, and the difficulty of making diagnosis of AEF is well-known. As promising results in the short-term effectiveness of thoracic endovascular aortic repair (TEVAR) promote its usage, the occurrence of AEF after TEVAR (post-TEVAR AEF) increases as one of the major complications. Therefore, we provide a review concerning the management strategy of post-TEVAR AEF. Although its representative symptom was reported as the triad of mid-thoracic pain and sentinel hematemesis followed by massive hematemesis, the symptom-free interval between sentinel hemorrhage and massive exsanguination is unpredictable...

PURPOSE: Report mid-term outcomes of thoracic endovascular aneurysm repair (TEVAR) with chimney and periscope grafts (CPG) in supra-aortic branches (SAB). METHODS: Retrospective analysis, from October 2009 to May 2014, of patients with aneurysms requiring TEVAR with zone 0/1/2 proximal landing in association with at least one CPG in the SAB. All patients were considered at high risk for conventional surgery. Peri-operative mortality and morbidity, retrograde type A dissection, maximum aortic transverse diameter (TD) and its post-operative evolution, endoleak, survival, freedom from cardiovascular re-interventions, and CPG freedom from occlusion during the follow-up were analysed...

OVERVIEW: To describe a new endovascular procedure for acute type A aortic dissection (TAAD) repair. METHODS: Between 2013 and 2016, 12 patients (average age 54±9.6 years; 10 men) with acute TAAD (mean EURO score 11.4%±3.2%, range 5-17) and unfit for surgery underwent thoracic endovascular aortic repair (TEVAR) with 2 periscope grafts to preserve blood supply to supra-aortic branches plus bypass grafting as needed. If the ascending aorta was dilated to >40 mm, sternotomy was performed to wrap the ascending aorta and reduce its diameter to accommodate the aortic stent-grafts...

BACKGROUND: Thoracic Endovascular Aortic Repair (TEVAR) has substantially decreased the mortality and major complications from aortic surgery. However, neurological complications such as spinal cord ischemia may still occur after TEVAR. S-100β is a biomarker of central nervous system injury, and oxidant injury plays an important role in neurological injury. In this pilot study, we examined the trends of S-100β and antioxidant capacity in the CSF during and after TEVAR. METHODS: We recruited 10 patients who underwent elective TEVAR...

Open total arch replacement (TAR) has become safer with refinements in cerebral protection techniques. The frequent extension of aortic arch aneurysms into the descending thoracic aorta customarily requires a two-staged conventional elephant trunk procedure, carrying relatively high mortality and morbidity risks and high rates of rupture in the interval between the two open surgeries. The technical demands and invasive nature of TAR has therefore precluded many high-risk patients from being surgical candidates for aneurysm repair...

Iliac arterial disease, unfavorable anatomy, and prior stenting all pose challenges to access in endovascular abdominal aortic repair (EVAR) and thoracic aortic repair (TEVAR). Iliac access injury during T/EVAR may lead to rupture, dissection, thrombosis, or distal ischemia. Some have advocated iliac stent prior to T/EVAR in patients with suboptimal iliac access. The rate of complication and iliac stent migration during subsequent T/EVAR is undocumented. This case report describes a unique instance of self expanding iliac stent migration during TEVAR which pinched the thoracic aortic endograft causing functional aortic coarctation...

We describe a rare case of acute type B dissection causing collapse of a previously placed infrarenal stent-graft, resulting in acute limb ischemia due to left iliac limb thrombosis in a 59-year-old male. The patient presented with acute back and abdominal discomfort radiating to his back, bilateral buttock stabbing discomfort, and left> right thigh and calf rest pain. CTA showed a spiral type B dissection with collapse of the proximal portion of the EVAR device and left limb occlusion. Urgent treatment with TEVAR distal to the left subclavian covered the entry tear and redirected the majority of the flow to the true lumen leading to near immediate expansion of the proximal portion of the EVAR device...

BACKGROUND: Promising results of thoracic endovascular aortic repair (TEVAR) in patients with complicated type B aortic dissection (TBAD) have been well documented. However, whereas early results have led many to hypothesize a benefit of TEVAR in uncomplicated patients, the natural history of TEVAR after the treatment of TBAD has yet to mature. In this review, we evaluated the available data to investigate whether longer term TEVAR warrants enthusiasm for all comers with TBAD. METHODS: A systematic review of the literature was performed searching specifically for studies assessing medium- and long-term outcomes after TEVAR for the treatment of TBAD...
