INTRODUCTION: Floating thrombus in an aberrant right subclavian artery is a rare cause of peripheral arterial embolic events. CASE REPORT: We report a 45-year-old woman who presented with an ischemia of the right superior limb from embolic event. The diagnosis of mobile thrombus in an aberrant right subclavian artery was obtained with transoesophageal echocardiography and computed tomography. After three weeks of oral anticoagulant therapy, there was no significant resolution of the thrombus, and a surgical treatment was performed to prevent further embolization. The surgical procedure consisted of thrombectomy and reimplantation of the aberrant right subclavian artery to the right carotid artery. Postoperative recovery was uneventful. CONCLUSION: This case report illustrates that transoesophageal echography and computed tomography are useful to detect mobile thrombus of the thoracic aorta and is warranted in any embolic event in young patients.
Aberrant right subclavian arteries are the commonest of the aortic arch anomalies. A bulbous enlargement of the proximal segment of the aberrant right subclavian artery at its origin from the aortic arch is also demonstrated suggestive of Kommer...
... is a rare vascular anomaly that is present from birth. It usually causes no symptoms and is often discovered as an incidental finding (such as through a barium swallow or echocardiogram). Occasionally the anomaly causes swallowing difficulty (dysphagia lusoria). Swallowing symptoms in children may present as feeding difficulty and/or recurrent respiratory tract infection. When aberrant subclavian artery causes no symptoms, treatment is not needed. If the anomaly is causing significant symptoms, treatment may involve surgery. Children with symptomatic aberrant subclavian artery should be carefully evaluated for additional vascular and heart anomalies ...

A 49-year-old man was incidentally found to have a right-sided descending thoracic aorta and multidetector computed tomography was performed. There was a right aortic arch with separate arch branches arising in the following order: left common carotid artery (Lt.CCA), right common carotid artery (Rt.CCA), right subclavian artery (Rt.SA), and left subclavian artery (Lt.SA), which was aberrant, all arising from a Kommerell diverticulum (KD) (1) and passing through the dorsal side of the trachea and esophagus. His coronary arteries had the dominant left circumflex artery and the hypoplastic right coronary artery. This anomaly is explained by atresia of left aortic arch between left carotid artery and left subclavian arteries in Edwards hypothetical double aortic arch (2) (type E). The left panelis a front view and the right panelis a back view. Separate arch branches and KD were recognized by these images. CRT = cranial; LAO = left anterior oblique.. ...
A two-year-old Border Collie presented with a three-month history of regurgitation. Investigation with plain radiography, digital fluoroscopy, endoscopy and CT angiography (CTA) confirmed the presence of an aberrant right subclavian artery causing dorsal oesophageal compression. In this report, CTA was used to depict the anatomy of an aberrant right subclavian vessel and to highlight the importance of this imaging modality to identify the structures involved in a vascular ring. This report also identifies a patient with a congenital vascular ring anomaly presenting with adult-onset regurgitation, which has been successfully managed with medical treatment. ...
Abstract: An unusual vascular ring anomaly consisting of a persistent right aortic arch and a left ligamentum arteriosum extending from the main pulmonary artery to an aberrant left subclavian artery and left aortic arch remnant complex was identified in a German shepherd dog and a great Dane. The left subclavian artery and left aortic arch remnant complex originated at the junction between the right distal aortic arch and the descending aorta and coursed dorsal to the oesophagus in a cranial direction. The attachment of the ligamentum arteriosum to the aberrant left subclavian artery was approximately 5 cm cranial to the point of origin of the aberrant left subclavian artery and left aortic arch remnant complex from the descending aorta in both dogs. This anomaly observed in both dogs is similar to an anomaly reported in humans, in which a persistent right aortic arch is found in conjunction with an aberrant left subclavian artery and a left aortic arch remnant (Kommerells diverticulum). ...
In human anatomy, the subclavian arteries are paired major arteries of the upper thorax, below the clavicle. They receive blood from the aortic arch. The left subclavian artery supplies blood to the left arm and the right subclavian artery supplies blood to the right arm, with some branches supplying the head and thorax. On the left side of the body, the subclavian comes directly off the aortic arch, while on the right side it arises from the relatively short brachiocephalic artery when it bifurcates into the subclavian and the right common carotid artery. The usual branches of the subclavian on both sides of the body are the vertebral artery, the internal thoracic artery, the thyrocervical trunk, the costocervical trunk and the dorsal scapular artery, which may branch off the transverse cervical artery which is a branch of the thyrocervical trunk. The subclavian becomes the axillary artery at the lateral border of the first rib. From its origin, the subclavian artery travels laterally, passing ...

A 65-year-old man presented to our hospital with a chief complaint of hoarseness. Chest radiography and computed tomography detected a right subclavian artery aneurysm. The aneurysm had a maximum diameter of 85 mm, and was associated with a mural thrombus and displacement of the trachea to the left, which led to airway stenosis. In case ventilatory insufficiency developed during anesthesia induction, an extracorporeal membrane oxygenator was prepared, followed by administration of anesthesia. Careful administration of anesthesia allowed for anesthesia management without the extracorporeal membrane oxygenator. We approached the periphery and the proximal portion of the aneurysm through a right subclavicular incision and partial median sternotomy, respectively. After excision of the aneurysm, we performed EPTFE prosthesis implantation. The patient fs postoperative course was uneventful, which led to postoperative improvement of the airway stenosis. The combination of a right subclavicular incision ...

Four patients were diagnosed with post-traumatic aneurysms including one iatrogenic aneurysm following fixation of a fractured clavicle; one patient experienced post-traumatic injury to subclavian artery; one with iatrogenic perforation of subclavian artery with bleeding into pleural cavity; and the last one with another iatrogenic injury resulting from attempts to place a central access line following surgical, restoration of patency within subclavian and axillary arteries. All patients underwent endovascular treatment with the use of self-expanding peripheral stentgrafts
In human anatomy, the subclavian arteries are two major arteries of the upper thorax (chest), below the clavicle (collar bone). They receive blood from the top (arch) of the aorta. The left subclavian artery supplies blood to the left arm and the right subclavian artery supplies blood to the right arm, with some branches supplying the head and thorax. On the left side of the body, the subclavian comes directly off the arch of aorta. On the right side of the body, the subclavian arises from the relatively short brachiocephalic artery (trunk) when it bifurcates into the subclavian and the right common carotid artery. The usual branches of the subclavian on both sides of the body are the vertebral artery, the internal thoracic artery, the thyrocervical trunk, the costocervical trunk and the dorsal scapular artery. The subclavian becomes the axillary artery at the lateral border of the first rib ...
Subclavian artery aneurysms are relatively rare in comparison with other peripheral aneurysms. We report a 65-year-old woman with multiple atherosclerotic aneurysms of the subclavian artery, aortic arch saccular aneurysm and abdominal aortic aneurysm
The left subclavian artery arises directly from the arch of the aorta, while the right arises from the brachiocephalic artery. The left lies deeper, is longer and more vertical. The relations of the second and third portions of the subclavian artery are alike on both sides. In its second portion, the artery lies behind the anterior scalene and in front of the scalenus medius muscle. At this point, it rises highest above the clavicle, usually about two centimeters. It is covered by the skin, the superficial fascia, the platysma muscle, the superficial layer of the deep fascia, the clavicular origin of the sternomastoid muscle, the posterior process of the deep fascia, the phrenic nerve, and the anterior scalene muscle. Above it lies the lowest of the three cervical trunks of the brachial plexus of nerves. Behind it are the scalenus medius muscle and the apex of the lung and of the pleura. Below it are the pleura, while below and in front of it is the subclavian vein. This portion gives off only ...
Aberrant right subclavian artery (ARSA), also called "lusorian artery", is a well known anatomical variant of the origin of the right subclavian artery, one of the most common congenital vascular abnormalities of the aortic arch (the prevalence among the population is 1-2% in according to different authors) [1-4]. Usually ARSA arises after the left subclavian artery and crosses the mediastinum behind the oesophagus and the trachea. For its particular position ARSA can cause compression to the close anatomical structures. Dysphagia lusoria is the most frequent symptom (in 10 % of cases). For the same reason the prolonged compression caused by medical devices such as nasogastric or endotracheal tubes on the arterial wall of the ARSA can cause severe injury, especially when an ARSA aneurysm is present. In rare cases it can lead up to an oesophageal fistula with profuse bleeding characterised by high mortality rate (till now less than 20 cases were reported in literature). In our case fistulisation ...
A 4-year-old boy was referred to our hospital for further treatment of pulmonary atresia (Fallot type), multiple systemic to pulmonary collateral arteries, and hypoplastic central pulmonary arteries. Echocardiography revealed cervical origin of the right subclavian artery, which originated close to the bifurcation of the internal and external carotid arteries (Figure 1, Movie I, and Movie II). The anomaly of the subclavian artery was confirmed with cardiac catheterization (Figure 2A, Movie III). In addition, the boy had dysmorphic features of conotruncal anomaly facies syndrome, and monosomy 22q11 was confirmed by cytogenetic testing. To improve antegrade perfusion of the hypoplastic central pulmonary arteries, the patient underwent creation of a central aortopulmonary shunt followed by interventional coil occlusion of a large collateral artery from the descending aorta. The postoperative course was complicated by formation of a seroma of the polytetrafluoroethylene shunt, diagnosed by computed ...

METHODS: The clinic data of 42 cases of congenital vascular from January 2010 to December 2013 was analyzed retrospectively (accounting for 1.04% congenital heart operations over the same period ). There were 26 male and 16 female patients, aged at surgery 24 days to 6 years (average 10.7 months). The diagnosis including pulmonary artery sling in 26 cases, double aortic arch in 10 cases, right aortic arch with aberrant left subclavian artery in 3 cases, pulmonary artery sling and right aortic arch with vagus left subclavian artery in 2 cases, pulmonary artery sling and left aortic arch with vagus right subclavian artery in 1 case ...
Four vessels arise sequentially from the aortic arch: the right common carotid artery, the left common carotid artery, the left subclavian artery and the aberrant right subclavian artery, which crosses upwards and to the right in the posterior mediastinum. It results from a disruption in the complex remodelling of the paired branchial arches, typically of the right dorsal aorta distal to the sixth cervical intersegmental artery. [1, 2 ...
face and neck. There are arteries that can be found on both sides of the body, and these are the right subclavian artery and the left subclavian artery. They form the internal thoracic artery, the thyrocervical trunk, the vertebral artery, and the costocervical artery. At the lateral first rib border, the subclavian artery becomes the auxiliary artery, while the subclavian artery on the left ...

Aberrant right subclavian artery (ARSA) or arteria lusoria is one of the most common congenital aortic arch anomaly with prevalence ranging from 1-2%. However, it is mostly asymptomatic and consequently often found sporadically during various diagnostic procedures with prevalence of 0.45% during coronary angiography.

Kutsche and Van Mierop4 described CORSA in 1984. They found this anomaly in 4 of 21 infants (19%) studied for aortic arch interruption. The origin of the vessel was seen along with the origins of the internal and external carotid arteries as a trifurcation, at the level of the thyroid gland. It then descended down the neck to enter the right arm. The right recurrent laryngeal nerve was seen to course around the origin of the right subclavian artery, much higher than normal. The pathogenesis of CORSA can be explained by impairment of fourth aortic arch development, before the involution of the right ductus caroticus (segment of the dorsal aorta between the third and fourth arches). The right ductus caroticus, which normally involutes at the 14-mm crown-rump length, is retained and forms the initial segment of the right subclavian artery at its origin from the common carotid bifurcation. The seventh intersegmental artery and the dorsal aorta below the level of the third arch form the rest of the ...

Right aortic arch with aberrant left subclavian artery (RAA/aLSCA) is a rare aortic arch anomaly. The clinical association of aLSCA stenosis with RAA/aLSCA has not yet been fully elucidated. The aim of this study was to investigate the diagnosis, incidence, management and outcome of aLSCA stenosis in infants with prenatally diagnosed RAA/aLSCA. Ten fetuses who were diagnosed as having RAA/aLSCA in Kyushu University Hospital between January 2011 and December 2014 were enrolled. The maternal and child medical records were reviewed to investigate sex, gestational age at the fetal diagnosis, gestational age and body weight at birth, the findings of computed tomography (CT), Doppler ultrasonography of the vertebral artery and angiography, and the complications and outcomes of aLSCA stenosis ...

Angiographies of the supra-aortic vessels by magnetic imaging have become common recently. So it was the purpose of this study to evaluate the imaging potential of different contrast agents.. Three contrast agents for magnetic resonance imaging are compared in angiographies of the supra-aortic arteries in a intraindividual study of 10 patients.. All applications of these contrast agents are performed with a flow of 2 ml/s. One contrast medium is applicated a second time with a reduced flow of 1 ml/s.. The angiographies of the supra-aortic vessels are evaluated by two experienced readers in a consensus reading. The signal/noise- and contrast/noise-ratio of anatomic vessel segments of the carotic and vertebral arteries are measured and compared to each other. ...
The CX Aortic Edited Cases session yesterday provided the unique opportunity for the audience to interact with experts and ask questions about the cases being presented. The first session focused on thoracic aortic cases and the remainder were abdominal aortic cases.. Michael Dake (Stanford, USA) presented a case with the TAG thoracic branch endoprosthesis (Gore) which is part of a US feasibility multicentre trial that has evaluated 22 patients (mean age 74.1±10.5 years, 54.5% male) undergoing branched thoracic endovascular aortic repair (B-TEVAR) in Ishimaru zone 2.. According to Dake, the endograft features a single side branch designed to facilitate aortic coverage proximal to the left subclavian artery, while maintaining branch vessel patency. Pathology treated included fusiform (n=10) or saccular (n=12) aneurysm, with a mean aortic diameter of 5.7±1.1cm.. Reporting on the progress of the trial, he said that the primary endpoints of device delivery and branch vessel patency was achieved in ...

Subclavian artery stenosis (SAS) is a significant form of peripheral artery disease, which may be a marker of diffuse atherosclerosis and increased risk for cardiovascular events. SAS can lead to symptomatic ischemia affecting the upper extremities, the brain, and, in some cases, the heart. In general, asymptomatic subclavian artery disease is treated with medical therapy and invasive treatment is reserved for the more symptomatic patients. This article discusses the evaluation of four patients with varying presentations of subclavian artery disease. [Rev Cardiovasc Med.
Transradial approach has gained progressive acceptance because it has been shown to have fewer hemorrhagic and vascular-related complications than the femoral approach does for diagnostic and therapeutic percutaneous coronary artery procedures. However, transradial access is not free of complications (1). A 43-year-old man was admitted with a non-ST-segment elevation acute coronary syndrome. A transradial coronary angiography was performed, followed by a drug-eluting stent implantation in the proximal descendent artery. Twenty-four hours after the procedure, he experienced an intense, continuous chest pain in his right upper hemi-thorax that irradiated to the right forearm, without electrocardiographic changes or elevated markers of myocardial damage, and required a high dose of analgesia. A computed tomogram was performed, revealing a subclavian artery pseudoaneurysm that compressed the brachial plexus (Figs. 1A to 1D). A few days later, an endovascular covered self-expanding stent was ...
A 68-year-old hypertensive man was admitted to our center for a non-ST-elevation acute coronary syndrome with normal troponin value. The clinical history was remarkable for enabliting pain of the left upper arm. After a positive stress test, the patient was scheduled for coronary angiography. The coronary angiography revealed severe 3-vessel coronary artery disease and a slight impairment of left ventricular function. Because the patient appeared to be a candidate for coronary surgery via the left internal mammary artery, a subclavian artery angiography was performed in the same session to exclude any subclavian artery stenosis and assess the suitability of the internal mammary artery as an arterial conduit. A tight stenosis of the middle portion of the left subclavian artery was detected (Figure, A). Because we believed that the patient had thoracic outlet syndrome (TOS), the patients left arm was mildly adducted and a magnified subclavian angiogram performed. The angiogram revealed that the ...

Results Thirty patients underwent LSA embolization during TEVAR. Six CCEs in 6 patients were performed from June 2013 to November 2013, while twenty-four CAEs in 24 patients were performed from December 2013 to March 2016. Technical success was achieved in all patients in both groups. No embolization-related complications or type II endoleaks from LSA were recorded during the follow-up period in all patients. In both groups, all embolic materials were detected in the proximal portion of the LSA from the LSA orifice to the vertebral artery origin and no vertebral artery occlusions were detected. The mean compression ratio of AVP II was 58 ± 5.9% of predicted length of standard procedure. In the CAE group, one AVP II was sufficient to achieve complete LSA occlusion in all patients. On the other hand, multiple coils (10.2 ± 2.7) were used in the CCE group (P , .01), resulting in a significantly lower cost incurred in the CAE group (CAE: 129,000 JPY vs. CCE: 639,600 ± 140,060 JPY; P , .01 ...
