INTRODUCTION: Chronic aortic dissection with aneurysm development that includes the aortic arch and/or thoraco-abdominal aorta (TAAA) is traditionally treated with open or hybrid surgery. Total endovascular treatment with fenestrated and branched stent grafts (F/B-EVAR) has recently been introduced as a less invasive alternative. The aim was to report short- and mid-term outcome from a single tertiary vascular center. METHODS: All patients with chronic aortic dissection treated with F/B-EVAR 2010-2019 at Uppsala University Hospital were identified...

BACKGROUND: Fetal double aortic arch (DAA) malformation is a rare congenital heart disease with few reported cases in the literature. We aimed to investigate the characteristics of prenatal ultrasound and postnatal computed tomography angiography (CTA) of DAA and to describe the associated anomalies and clinical outcomes to improve prenatal diagnosis and assist in perinatal management. METHODS: The obstetric ultrasound imaging databases of seven tertiary referral centers were reviewed retrospectively to identify fetuses with a prenatal diagnosis of DAA between January 2013 and December 2018...

We report a case of a 69-year-old male who was planned for a transcatheter aortic valve replacement (TAVR) with a 26 mm Sapien 3 Valve (Edwards Lifesciences, Irvine, California) for the treatment of symptomatic severe aortic stenosis. During rapid ventricular pacing and implantation of the TAVR valve, there was a loss of pacing capture and subsequent embolization of the valve into the aortic arch. Retrieval of the embolized valve was attempted unsuccessfully using several techniques. Finally, by using a 34 mm Evolut R Valve (Medtronic, Minneapolis, Minnesota), we were able to secure the embolized valve in the transverse segment of the aortic arch without compromising the branch vessels...

BACKGROUND: A right sided aortic arch (RAA) and an aortic diverticulum (AD) are a rare congenital anomaly associated with an aortic rupture and dissection. Recently, various methods for the surgical management have been described to treat RAAs and ADs. CASE REPORT: We describe a case of an RAA with a mirror image branching (RAMI) and AD in a teenager who complained of chest pain. We planned a total arch replacement with the frozen elephant trunk technique. Further, we needed to devise a way to reconnect the cerebral vessels because of his small arch anatomy and limited space in the mediastinum...

Giant cell arteritis (GCA) is a chronic granulomatous vasculitis of unknown aetiology occurring in the older patients and affecting mostly the cranial branches of the arteries originating from the aortic arch. GCA is associated with polymyalgia rheumatica (PMR). Clinical features of the disorder include headache, scalp tenderness, jaw claudication, temporal artery abnormalities on physical examination, vision changes, and symptoms associated to PMR. Systemic manifestations include fever, anorexia and weight loss while less rare manifestations are related to the nervous system, the respiratory system, the pericardium and extra-cranial large vessels...

Background Endovascular repair has become a viable alternative for aortic pathological features, including those located within the aortic arch. We investigated the anatomic suitability for branched thoracic endovascular repair in patients previously treated with conventional open surgery for aortic arch pathological features. Methods and Results Patients who underwent open surgery for aortic arch pathological features at our institution between 2000 and 2018 were included. Anatomic suitability was determined by strict compliance with the anatomic criteria within manufacturers' instructions for use for each of the following branched thoracic stent grafts: Relay Plus Double-Branched (Terumo-Aortic), TAG Thoracic Branch Endoprosthesis (W...

Vascular rings (VRs) are rare aortic arch anomalies that may present with a wide variety of symptoms related to esophageal and/or airway compression. We reviewed our surgical experience in both symptomatic and asymptomatic children. All children (n = 58) who underwent surgical repair of VRs or slings (mean age 27.4±45.60 months; 36 males [62%]) between March 2000 and April 2020 were included. The most common anatomic variant was a right aortic arch (RAA) with aberrant left subclavian artery (ALSCA)(n = 29; 50%)...

Introduction The brachiocephalic artery (BCA) is the largest branch that arises from the aortic arch, which varies in length. The present study focuses on BCA length and its probable correlation with height and torso length. Methods The BCA length (from the artery's origin to the arcus aortae), the length of the torso, and height were measured in 76 embalmed adult human cadavers of Caucasian (Hellenic) origin. Results A total of 74 arteries were measured (36 females and 38 males). The mean length was found to be 3...

ATF3 (activating transcription factor 3) is a member of the mammalian activation transcription factor/cAMP-responsive element-binding (CREB) family. It plays a role in inflammation and innate immunity, and suggests that ATF3 is associated with atherosclerosis. In our study, we analyzed datasets of atherosclerosis from the NCBI-GEO (Gene Expression Omnibus) database and found that expression levels of ATF3 were lower in macrophages from ruptured atherosclerotic plaques than from stable atherosclerotic plaques...

OBJECTIVES: Aortic dissection involving the ascending aorta and aortic arch is a serious condition. Treatment using traditional surgical methods has certain disadvantages. This study investigated the effectiveness of thoracic endovascular repair of aortic dissection using an external prefenestrated stent. METHODS: We present a series of aortic dissection cases involving the ascending aorta and aortic arch treated with an external prefenestrated stent. RESULTS: Postoperative follow-up of the patients showed that all stents were released at the proper position and that branch vessels were not occluded, and there were no instances of type I endoleak...

Aortogenic embolic stroke (AES) is an important stroke mechanism. However, as many stroke patients have aortic atheromatous lesions, it is unclear whether these lesions are the cause of these strokes. Cholesterol crystals are the solid, crystalline form of cholesterol that is found in atherosclerosis, but not in cardiac diseases such as atrial fibrillation, valvular diseases, and cardiomyopathy. Therefore, if a cholesterol crystal is found in a thrombus removed by mechanical thrombectomy (MT), this makes it possible to diagnose a patient as having an atheromatous lesion...

Extracorporeal membrane oxygenation (ECMO) is increasingly deployed to provide percutaneous mechanical circulatory support despite incomplete understanding of its complex interactions with the failing heart and its effects on hemodynamics and perfusion. Using an idealized geometry of the aorta and its major branches and a peripherally inserted return cannula terminating in the iliac artery, computational fluid dynamic simulations were performed to (1) quantify perfusion as function of relative ECMO flow and (2) describe the watershed region produced by the collision of antegrade flow from the heart and retrograde ECMO flow...

OBJECTIVES AND BACKGROUND: Coarctation of the aorta represents 5-8% of all congenital heart disease. Although balloon expandable stents provide an established treatment option for native or recurrent coarctation, outcomes from transverse arch (TAO) stenting, including resolution of hypertension have not been well studied. This study aims to evaluate immediate and midterm results of TAO stenting in a multi-center retrospective cohort. METHODS: TAO stenting was defined as stent placement traversing any head and neck vessel, with the primary intention of treating narrowing in the transverse aorta...

Background and objectives: Anatomical dissection is an indispensable means of acquiring knowledge about the variability of the human body. We detected the co-existence of several arterial variations within one female anatomic specimen during routine anatomical dissection. The aim of this study was to evaluate if this status is a regular pattern in any of other vertebrates. Materials and Methods : Besides of a meticulous anatomic dissection, we performed a literature review concerning the frequency, the phylogenesis, and ontogenesis of all of these variations...

Right aortic arch anomalies are a spectrum of malformations that include right aortic arch with mirror image branching, right aortic arch with an aberrant left subclavian artery, and double aortic arch. Although these are rare anomalies, they are of importance as they form vascular rings, which can cause symptoms in the newborn period. These anomalies are not detected with routine cardiac views, and it is only with the 3-vessel, and the 3-vessel tracheal view that they can be identified and characterized. We describe specific sonographic findings of these anomalies on the 3-vessel and the 3-vessel tracheal view...

Sarv Priya, Prashant Nagpal
A double aortic arch (DAA) with atresia is an uncommon cause of a symptomatic vascular ring resulting in trachea-esophageal compression. An atretic double aortic arch can resemble the right aortic arch with a mirror image branching pattern or the right arch with an aberrant left subclavian artery depending upon the level of atresia. The double aortic arch with atresia is difficult to detect on pre-surgical computed tomography angiography or magnetic resonance angiography due to a lack of contrast in the obliterated arch segment...
