We report a 78-year-old man who presents progression of his aneurysmatic pathology with previous abdominal infrarenal aortic surgery 20 years later. The computed tomography (CT) scan showed proximal degeneration of the infrarenal aorta, left iliac aneurysm and a new descending thoracic aneurysm close to the aortic arch. The surgical treatment was staged in two times due to the evolution of the aneurysm measures. First, the thoracic and the infrarenal aneurysms were covered each one with endoprosthesis. Four years later the iliac disease was solved with a branched specific iliac endograft...

OBJECTIVE/BACKGROUND: The aim of the study was to assess a model of physician modified scalloped stent graft (PMSG) on currently available thoracic aortic devices to extend the proximal landing zone in either zone 2, 1 or 0 of the aortic arch while preserving flow in the supra-aortic vessels on human cadaveric aorta. METHODS: Fresh human aortas were harvested at autopsy from adult subjects. A proximal scallop was made on the stent grafts based on direct measurements on the aortas to extend the proximal landing zone in zone 0 (n = 5), zone 1 (n = 5), and zone 2 (n = 5)...

PURPOSE: To describe a quick, simple, and reliable technique to confirm successful catheterization of a branched thoracic endograft's inner branch. TECHNIQUE: Accurate cannulation of inner branches can be verified through insertion and mild retraction of a Universal Flush angiographic catheter, whose tip hooks the branch and slightly opens. CONCLUSION: The use of an angiographic catheter with a curved tip is a safe and easy procedure that can be adopted to check the correct position inside the branch of an endograft designed for treatment of the aortic arch...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) for thoracic aortic aneurysms (TAAs) is in rapid expansion due to its minimal invasiveness. However, TEVAR for an arch aneurysm with a straight stent graft needs surgical reconstruction for supra-aortic vessels. A branched stent graft pioneered by Inoue (branched Inoue Stent Graft [ISG]) has been expected to resolve this problem, but its utility remains to be established in the real clinical setting. This study evaluated the long-term clinical outcome of branched ISGs for TAAs...

The present study was aimed at working out a methodology combining clinical, haemodynamic, and functional parameters of lesions of arterial basins in patients presenting with concomitant lesions of the aortic arch branches and arteries of lower extremities. The authors retrospectively investigated the results of examining a total of 181 patients operated on for concomitant atherosclerotic lesions of the aortic arch branches, terminal portion of the abdominal aorta, and lower limb arteries. In patients subjected as the first stage to interventions on the aortic arch branches (Group 1), the index of severity of the lesion of the aortic arch branches (Cs) was higher than in those from Groups 2 and 3...

Variations in the origins and the branching pattern of the carotid system of arteries are not uncommon. Here we report a rare case of higher bifurcation of the common carotid artery (CCA) (at the level of the greater cornu of the hyoid bone), thyrolinguofacial trunk (TLFT) originating from the CCA, superior laryngeal artery (SLA) arising from the external carotid artery (ECA) on the left side, and linguofacial trunk arising from the ECA on the right side. In the present case, the CCA and carotid bifurcation may have arisen from the second aortic arch...

BACKGROUND: The chimney technique has been developed for the treatment of complex aortic aneurysms. We analyzed the midterm to long-term outcomes of this approach from a single- centre experience. METHODS: From October 2008 to July 2016, 58 patients underwent endovascular aortic aneurysm repair using the chimney technique. Indications for treatment were thoracic aortic aneurysm (TAA) (n = 11), thoracoabdominal aortic aneurysm (TAAA) (n = 2), pararenal aortic aneurysm (PAAA) (n= 15), aortoiliac/isolated hypogastric artery aneurysm (n = 25), type I endoleak after previous TEVAR/EVAR (n=4), proximal pseudoaneurysm after AAA open repair (n = 1)...

Donkeys are a member of the horse family (Equidae) and share a common ancestor. However, in morphological terms, donkeys and horses are regarded as two separate subgenus. Given variations in the branching pattern of the brachiocephalic trunk (BCT) in different species of animals and the use of donkeys in anatomy courses at colleges of veterinary medicine, we conducted this study in order to investigate the branching patterns of BCT and to describe detailed morphological information regarding donkeys. Seventeen mature donkeys were examined following euthanasia by exsanguination from the common carotid artery under general anaesthesia...

INTRODUCTION: Prophylactic open surgery is the standard practice in patients with connective tissue and thoraco-abdominal (TAAA) and aortic arch disease. Branched and fenestrated devices offer a less invasive alternative but there are concerns regarding the durability of the repair and the effect of the stent graft on the fragile aortic wall. The aim of this study was to evaluate mid-term outcomes of fenestrated and/or branched endografting in patients with connective tissue disease. METHODS: All patients with connective tissue disease that underwent TAAA or arch aneurysm repair using a fenestrated and/or branched endograft in a single high volume centre between 2004 and 2015 were included...

OBJECTIVES: The first publication of Loeys-Dietz syndrome (LDS) described aortic rupture at young ages. Experience with new LDS types showed that the clinical course varies, and thresholds for prophylactic surgery are discussed. As this is an uncommon disease, experience needs to be shared. METHODS: Retrospective review of patients with LDS types 1-4 undergoing cardiovascular surgery during the years 1991-2016. RESULTS: Thirty-five patients (including 6 children with LDS2) underwent 57 operations...

OBJECTIVES: Although conventional open repair is our preference for patients with aortic arch aneurysms, we have often chosen thoracic endovascular aneurysm repair (TEVAR) with a handmade branched stent graft (bTEVAR) in high-risk patients. The aim of this study was to compare the midterm clinical outcomes of our bTEVAR technique to those of the open repair. METHODS: Between January 2007 and December 2014, we treated 129 patients with aortic arch aneurysm by means of either conventional open repair (OPEN, n  = 61) or bTEVAR ( n  = 68) at our institution...

BACKGROUND: Left aberrant subclavian artery (LASA), is a type of right aortic arch (RAA) branching, which takes-off distally to the right subclavian artery and usually crosses behind the esophagus to the left upper limb. Taking into account the rarity of RAA, LASA is much more rarely seen than the right aberrant subclavian artery (RASA) originating from the left aortic arch. However, RAA may be associated with much more frequent presence of LASA, than left aortic arch with RASA. Anatomical LASA characteristics were not described up to date...
