Endovascular aortic repair (EVAR) has been shown to be a valid and minimally invasive alternative to open abdominal aortic aneurysm repair. A major shortcoming for EVAR is the need to submit patients to regular follow-up to detect potential complications such as endoleak, limb occlusion, aneurysm expansion, aneurysm rupture, infection, structural failure, and migration. In this case report, we describe an uncommon case of late type III endoleak due to complete detachment of the stent-graft main body segment from its suprarenal uncovered fixation stent...

Endovascular correction of aortic arch pathology remains a challenge, with a variety of techniques proposed over the years to minimize complications and enhance the probability of a successful result. A variety of approaches have been developed in order to deal with the aortic arch pathology and its idiosyncrasies. We review potential interventional techniques for the repair of aortic arch pathologies, beginning with conventional aortic arch surgery, followed by hybrid treatments and those along the endovascular spectrum (parallel and fenestrated endografts, scalloped endografts, and ascending and new branched endografts)...

Right-sided aortic arch (RAA) is a rare congenital disorder. We describe herein two cases of thoracic aortic aneurysm with a right aortic arch and right-sided descending aorta treated with thoracic endovascular aortic repair (TEVAR). In one case, a 70-year-old man with Edwards type 1 RAA underwent TEVAR using a Relay stent-graft (Bolton Medical, Barcelona, Spain). In another case, a 72-year-old woman with Edwards type 3 RAA underwent TEVAR using a Kawasumi Najuta stent-graft (Kawasumi Laboratories, Inc., Tokyo, Japan) with the "buffalo horn chimney technique", our original method for left subclavian artery flow preservation...

OBJECTIVE: Late thoracic aneurysms develop in 5% to 12% of patients having undergone open repair for coarctation of the aorta (CoA). We report our early results for thoracic endovascular aortic repair for pseudoaneurysms after CoA repair. METHODS: From 2008 to 2013, data regarding demographics, aneurysm morphology, procedure, and follow-up were collected prospectively on all patients treated for pseudoaneurysms after CoA repair. Retrospective analysis of identified patients was then performed...

We show the use of a proximal scalloped stent graft for an pseudoaneurysm of the descending thoracic aorta to avoid occlusion of the left subclavian artery. A 63-year-old man with sudden onset dysphonia was diagnosed with left vocal fold paralysis and the presence of a lung mass. A computed tomography scan revealed saccular dilatation of the aortic arch (proximal neck: <10 mm) with suggestive images of a penetrating ulcer and degenerative pseudoaneurysm. A RELAY Plus thoracic stent graft (Bolton Medical, Sunrise, FL) with proximal scallop was implanted to preserve the left subclavian artery...

We report two cases of descending thoracic aorta floating thrombus treated with Bolton Relay thoracic free-flow stent graft. The patients had symptoms of lower limb ischemia; they underwent preoperative angiography and CTscan, then we proceeded with endovascular exclusion of the thrombus from the systemic circulation. At 12 months, the graft was still patent in both patients, without any signs of endoleak.

Thoracic endografting has been proposed as an effective alternative to open repair to treat several aortic pathologies. Cranial migration is one of the critical issues concerning long-term durability. The scalloped thoracic endograft was proposed to improve distal sealing and fixation crossing the diaphragm. The objective of this study was to evaluate technical feasibility and experience with a custom-made scalloped thoracic endograft using the Relay platform (Bolton Medical, Sunrise, FL) in selected cases...

Our goal was to achieve complete proximal sealing in severe aortic neck angulation (SNA) during endovascular aneurysm repair (EVAR) of a patient with an abdominal aortic aneurysm (AAA) unfit for surgery. An 82-year-old patient with an infrarenal AAA of 9.8 cm with an SNA of 90 degrees was admitted for acute coronary syndrome. Following coronary treatment, the patient was considered unfit for surgery and therefore was evaluated for EVAR. Aneurysm sac exclusion was obtained with the deployment of a Powerlink bifurcated graft (Endologix Inc, Irvine, CA) inside a Relay thoracic endograft (Bolton Medical, Florida) placed just below the most distal renal artery...

PURPOSE: The aim of this study was to evaluate the efficacy and safety of thoracic endovascular aortic repair with a newly designed Relay thoracic stent graft (Bolton Medical, Sunrise, FL). DESCRIPTION: Between 2005 and 2007, 22 patients (71.8 +/- 8.5) received 24 stent grafts. Indications were aneurysms (n = 13), penetrating atherosclerotic ulcers (n = 7), and dissections (n = 2). Due to the proximity of the lesions to the aortic arch, rerouting procedures (ie, subclavian transposition [n = 1], double transposition [n = 12], and total arch rerouting [n = 6] were performed pre-interventionally; three patients did not undergo rerouting)...

It is well established that the vestibular system influences the sympathetic nervous system and the respiratory system; presumably, vestibulosympathetic and vestibulorespiratory responses participate in maintaining stable blood pressure and blood oxygenation during movement and changes in posture. Many brainstem neurons that generate vestibulospinal reflexes integrate signals from the labyrinth and neck muscles to distinguish between head movements on a stable body and whole body movements. In the present study, responses were recorded from the splanchnic (sympathetic), hypoglossal (inspiratory) and abdominal (expiratory) nerves during stimulation of the C2 dorsal root ganglion or C2 or C3 nerve branches innervating dorsal neck muscles...

BACKGROUND: There is some evidence to suggest that dysfunction in the sensory system of the neck may result in a gamut of signs and symptoms. However, a sound understanding of the somatosensory system in the neck and its normal influence on the central nervous system is essential before signs and symptoms can be identified as representations of ill health or disease arising from the neck. OBJECTIVE: To briefly review current knowledge of the somatosensory system of the neck and to consider its connections and influence on the central nervous system...

In the decerebrate cat, recordings were made from neurons in the caudal medullary raphe nuclei to determine if they responded to electrical stimulation of the vestibular nerve and thus might participate in vestibulosympathetic reflexes. Many of these cells projected to the upper thoracic spinal cord. The majority (20/28) of raphespinal neurons with conduction velocities between 1 and 4 m/s received vestibular inputs; 13 of the 20 were inhibited, and 7 were excited. Since many raphespinal neurons with similar slow conduction velocities are involved in the control of sympathetic outflow, as well as in other functions, these cells could potentially relay vestibular signals to sympathetic preganglionic neurons...

Experiments were performed on rats to determine the location of thalamic projecting neurones in the medulla which receive direct contacts from neck primary afferents. The medullary terminations of primary afferents from the cervical region were identified by silver staining their degenerating terminals, diffusely filling their axons with horseradish peroxidase (HRP), or reacting for transganglionically transported HRP applied to muscle or cutaneous nerves. Neurones projecting to the ventrobasal thalamus were identified in the same experimental animals by using retrograde transport of HRP or Fluoro-Gold...
