BACKGROUND: The best management strategy for the left subclavian artery (LSA) in pathologic processes of the aorta requiring zone 2 thoracic endovascular aortic repair (TEVAR) remains controversial. We compared LSA coverage with or without revascularization as well as the different means of LSA revascularization. METHODS: A retrospective chart review was conducted of patients with any aortic diseases who underwent zone 2 TEVAR deployment from 2007 to 2014. Primary end points included 30-day stroke and 30-day spinal cord injury (SCI)...

BACKGROUND: Patients suffering blunt thoracic aortic injury (BTAI) can be treated by use of thoracic endovascular aortic repair (TEVAR). In this setting, the coverage of the left subclavian artery (LSA) is frequently necessary. Nevertheless, the functionality of the upper left extremity after TEVAR had been rarely analyzed. Thus, this study intends to underline the safety of TEVAR as well as to determine the functionality of the left arm after coverage of the LSA. METHODS: All patients suffering from BTAI treated by endovascular means in 3 centers (Aachen [Germany], Maastricht [Netherlands], and Innsbruck [Austria]) between 1996 and 2009 were retrospectively analyzed...

PURPOSE: To evaluate risk factors for early (<30 days) type I endoleak following thoracic endovascular aortic repair (TEVAR). METHODS: A retrospective study was conducted of 439 consecutive patients (mean age 74.0±10.0 years; 333 men) who underwent TEVAR at a single center between June 2006 and June 2013. Pathologies included 237 aortic arch aneurysms and 202 descending thoracic aortic aneurysms (dTAA). Maximum TAA diameter was 63.6±13.7 mm. Among the distal aortic arch aneurysms, 124 required coverage of the left subclavian artery (LSA), while the remaining 113 arch aneurysms had debranching (n=40), the chimney technique (n=52), and a branched stent-graft (n=13)...

BACKGROUND: Controversy exists as to whether revascularisation of the left subclavian artery (LSA) confers improved outcomes in patients undergoing thoracic endovascular aortic repair (TEVAR). Even though preemptive revascularisation of the LSA has theoretical advantages, including a reduced risk of ischaemic damage to vital organs, such as the brain and the spinal cord, it is not without risks. Current practice guidelines recommend routine revascularisation of the LSA in patients undergoing elective TEVAR where achievement of a proximal seal necessitates coverage of the LSA, and in patients who have an anatomy that compromises perfusion to critical organs...

BACKGROUND: Practice guidelines for management of the left subclavian artery (LSA) during thoracic endovascular aortic repair (TEVAR) are based on low-quality evidence, and there is limited literature that addresses optimal revascularization techniques. The purpose of this study was to compare outcomes of LSA coverage during TEVAR and revascularization techniques. STUDY DESIGN: We performed a single-center retrospective cohort study from 2001 to 2013. Patients were categorized by LSA revascularization and by revascularization technique, carotid-subclavian bypass (CSB), or subclavian-carotid transposition (SCT)...

Endovascular repair of blunt aortic injury is now a first-line approach in management. This can warrant coverage of the left subclavian artery (LSA), which could lead to posterior strokes. In this case report, we present a severe complication of endovascular repair of a traumatic aortic aneurysm. A 53-year-old man presented with blunt aortic injury, endovascular repair was carried out where the left subclavian artery was covered. The intervention had a 100% technical success. Twelve hours later, he was discovered to have quadriplegia, a CT scan showed a large left cerebellar infarction extending to the medulla oblongata and proximal spinal cord...

We report the case of a 76-year-old man presented with three saccular aneurysms at the aortic arch and descending thoracic aorta. A two-staged hybrid approach was performed. A left common carotid-to-left subclavian artery bypass and a custom-made fenestrated endograft were used for the two proximal aneurysms. The endograft deployment was complicated by the unadverted coverage of the left common carotid artery ostium, promptly corrected with the chimney technique. The endovascular treatment was completed with the third endovascular aneurysm exclusion 5 months after the first procedure to reduce the risk of spinal cord ischemia...

We consider model selection and estimation in a context where there are competing ordinary differential equation (ODE) models, and all the models are special cases of a "full" model. We propose a computationally inexpensive approach that employs statistical estimation of the full model, followed by a combination of a least squares approximation (LSA) and the adaptive Lasso. We show the resulting method, here called the LSA method, to be an (asymptotically) oracle model selection method. The finite sample performance of the proposed LSA method is investigated with Monte Carlo simulations, in which we examine the percentage of selecting true ODE models, the efficiency of the parameter estimation compared to simply using the full and true models, and coverage probabilities of the estimated confidence intervals for ODE parameters, all of which have satisfactory performances...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) is widely used for treatment of traumatic aortic injury (TAI). Stent graft coverage of the left subclavian artery (LSA) may be required in up to 40% of patients. We evaluated the long-term effects of intentional LSA coverage (LSAC) on symptoms and return to normal activity in TAI patients compared with a similarly treated group whose LSA was uncovered (LSAU). METHODS: Patients were identified from a prospective institutional trauma registry between September 2005 and July 2012...
