INTRODUCTION: Segmental arterial mediolysis (SAM) is a rare nonatherosclerotic, noninflammatory vasculopathy causing arterial wall necrosis that leads to strictures, dissections, and aneurysms, particularly in medium-sized abdominal arteries. Awareness of SAM is important because, unlike vasculitides, immunosuppressive treatment may worsen the disease process. CASE: A 58-year-old man with multiple medical comorbidities presented with acute epigastric pain and a right incarcerated inguinal hernia that was interpreted as showing bowel strangulation on computed tomography...

PurposeWe delineate the clinical spectrum and describe the histology in arterial tortuosity syndrome (ATS), a rare connective tissue disorder characterized by tortuosity of the large and medium-sized arteries, caused by mutations in SLC2A10.MethodsWe retrospectively characterized 40 novel ATS families (50 patients) and reviewed the 52 previously reported patients. We performed histology and electron microscopy (EM) on skin and vascular biopsies and evaluated TGF-β signaling with immunohistochemistry for pSMAD2 and CTGF...

OBJECTIVE: Endovascular treatment of vertebral intradural dissecting aneurysms is complex and requires different strategies for each case. The current study aims to classify these aneurysms for an easy selection of optimal strategies for endovascular therapy. MATERIALS AND METHODS: This study is a retrospective evaluation of 10 patients harbouring a vertebral intradural dissecting aneurysm (including 6 female and 4 male patients). The clinical, procedural, and angiographic data were evaluated...

Objectives Cardiovascular disease is a leading cause of sudden unexpected death even in hospitalized patients. Infectious aortitis is a rare disease that has the potential to cause aortic tears and hemorrhage followed by sudden death. The aim of this study was to reveal the clinicopathological features of infectious aortitis that are related to sudden unexpected death. Methods We retrospectively reviewed 1,310 autopsy cases over 15 years and selected the cases involving patients who died suddenly due to aortic tears...

The study purpose is to optimize modeling parameters, specifically segmentation spacing and centerline extraction, to efficiently construct accurate 3D aortic models. Models are constructed by centerline extraction and orthogonal 2D segmentations. We examine the effect of segmentation interval spacing (2, 1, 0.5, 0.25 cm) and orthogonal segmentation and centerline extraction iteration (one, two, three iterations) for constructing models of Healthy, Tortuous, Aneurysmal, and Dissected human thoracic aortas...

Background: Pulmonary sequestration (PS) is a rare congenital pulmonary malformation. In this study, we aimed to retrospect and evaluate the diagnosis, treatment, and outcomes of PS in 28 patients at our institute. Methods: The files of 28 patients with PS who were treated with surgery (21 cases) or endovascular intervention (7 cases) between May 2005 and June 2016 from a single institute were retrospectively reviewed. The following data of all patients were analyzed: age, sex, clinical symptoms, diagnostic methods, operative techniques, and treatment outcomes...

OBJECTIVE: To assess the mid-term outcomes and feasibility of branched endovascular repair (b-EVAR) of ruptured thoracoabdominal aortic aneurysms (rTAAAs). METHODS: All patients undergoing b-EVAR of rTAAAs between 2011 and 2016 were included. Pre-, intra and postoperative imaging was reviewed to assess technical success, outcomes, and feasibility of b-EVAR in the emergent setting. RESULTS: Eleven emergency b-EVAR of rTAAAs (10 aneurysms and 1 chronic dissection) were performed using off-the-shelf (OTS) branched stentgrafts...

PurposeSmooth muscle dysfunction syndrome (SMDS) due to heterozygous ACTA2 arginine 179 alterations is characterized by patent ductus arteriosus, vasculopathy (aneurysm and occlusive lesions), pulmonary arterial hypertension, and other complications in smooth muscle-dependent organs. We sought to define the clinical history of SMDS to develop recommendations for evaluation and management.MethodsMedical records of 33 patients with SMDS (median age 12 years) were abstracted and analyzed.ResultsAll patients had congenital mydriasis and related pupillary abnormalities at birth and presented in infancy with a patent ductus arteriosus or aortopulmonary window...

Increasing researches suggest that inflammatory response is involved in vascular remodeling, which plays an important role in the development of aortic dissection. Glucocorticoids have been widely used in the clinical practice due to its powerful and effective anti-inflammatory property. However, the potential relationship between glucocorticoids and aortic dissection was still obscure. This study sought to elucidate the effect of glucocorticoids on the development and progression of aortic dissection, and the potential mechanism involved...

Eric E Roselli
The number of aorta procedures performed annually in the United States has grown substantially during the past decade. Cleveland Clinic is a leader in research on the risk of aortic dissection in patients with a bicuspid or tricuspid aortic valve and associated aneurysm, which has led to changes in the recommendations of when to operate. Safety and efficacy data support more proactive treatment for most patients with thoracic aortic aneurysm and/or dissection with a growing emphasis on the need to provide life-long care to patients with aortic conditions...

OBJECTIVE: Acute dissecting aneurysms of the posterior circulation are a rare cause of SAH. Established endovascular treatment options include PAO and stent-assisted coiling, but appear to be associated with an increased risk of ischemic stroke. Vessel reconstruction with flow-diverters is an alternative treatment option, however, its safety and efficacy in the acute stage remains unclear. METHODS: Multi-centric retrospective analysis of 15 consecutive acutely ruptured dissecting posterior circulation aneurysms treated with flow-diverters...

BACKGROUND: Patients with acute severe headache, normal neurological examination, and a normal noncontrast head computed tomography (NCCT) may still have subarachnoid hemorrhage, cerebral venous thrombosis (CVT), cervical arterial dissection, or reversible cerebral vasoconstriction syndrome (RCVS). Computed tomography angiography (CTA) is used increasingly in the emergency department for evaluating this, but its added value remains controversial. METHODS: We retrospectively collected data on the diagnostic yield of CTA in patients with acute severe headache, normal neurological examination, and normal NCCT who received additional CTA in the acute phase in 2 secondary referral centers for vascular neurology...

Late aneurysm formation in the proximal aorta or distal aortic arch is a recognized sequela of untreated stenosis of the aortic isthmus and is associated with substantial risk of aortic rupture. We describe the case of a 44-year-old man with untreated coarctation of the aorta who presented with a prestenotic dissecting thoracic aortic aneurysm. He declined surgery because he was a Jehovah's Witness. Instead, we performed emergency endovascular aortic repair in which 2 stent-grafts were placed in the descending aorta...

OBJECTIVE: This study investigated the growth and behavior of the ascending aorta in patients with descending thoracic aortic disease. METHODS: We examined 200 patients with descending thoracic aortic disease including acute type B dissection (n = 95), chronic type B dissection (n = 38), intramural hematoma (n = 23), and thoracoabdominal aortic aneurysms (n = 44). Images from computed tomography and magnetic resonance imaging were evaluated after three-dimensional reconstruction to examine the growth rate in those with >1 year of imaging follow-up (n = 108)...

BACKGROUND: A single-institutional study comparing early and long-term outcomes of thoracic endovascular aortic repair (TEVAR) and open surgical repair (OSR) was performed to determine the appropriate treatment option for descending thoracic aortic aneurysm (DTAA). METHODS: Between 2005 and 2014, 438 DTAA patients were treated (TEVAR, 88; OSR, 350). Acute dissection and traumatic injury were excluded. Perioperative and follow-up data were reviewed. Stratified analyses were conducted to identify patients most likely to benefit from TEVAR...

A 69-year old man presented to the emergency department with back pain and paraplegia. Computed tomography showed acute type A aortic dissection with primary tear right below the origin of the left subclavian artery. He had undergone endovascular aneurysm repair (EVAR) 13 months earlier, and the previously inserted EVAR graft totally collapsed. Total arch replacement covering primary entry tear was performed. Femoral pulse was undetected prior to surgery, but was monitored post-surgically after cardiopulmonary bypass weaning...
