The left aortic arch with an aberrant right subclavian artery, or arteria lusoria, is the most common aortic arch anomaly, occurring in 0.5-2.5% of individuals. In such cases, the angular course of the arteria lusoria to the ascending aorta imposes difficulty in passing a guide wire to the ascending aorta during right transradial catheterization. Here, the case of a 53-year-old woman with intermittent chest tightness and coughing is reported. Aberrant right subclavian artery (arteria lusoria) was diagnosed via aortogram during right transradial coronary angiography. Compression of the esophagus and trachea by the aberrant right subclavian artery was demonstrated by chest computed tomography (CT).

An aberrant right subclavian artery is a rare congenital anomaly that usually does not produce symptoms. Symptomatic patients require surgical intervention. Ligation of the aberrant artery through a left thoracotomy has been advocated as the operation of choice. If development of vertebrobasilar insufficiency is anticipated, division and ligation of he aberrant artery and its anastomosis to the right common carotid artery or aortic arch are performed at a second operation. Experience with successful surgical treatment of a patient with an aberrant subclavian artery is described. A right thoracotomy incision was utilized for division of the subclavian artery and for reestablishment of arterial continuity with Dacron graft. Postoperative arteriography demonstrated a good reconstruction and normal blood flow was established to the right upper extremity.

Aberrant right subclavian arteries were experienced in two young children. This is a rare aortic arch anomaly that usually does not produce symptoms. Symtomatic patients require surgical interventions.We describe two young children who had aberrant right subclavian artery with symptoms of difficulty in swallowing and respiratory problems. Diagnosis was made by esophagography, aortography and 3-Dimension chest CT. Operation had been advocated through right thoracotomy without difficulty for ligation, division and anastomosis to the ascending aorta. Dysphagia lusoria was immediately relieved and postoperative course was uneventful. We consider that the right thoracotomy is the choice of operative approach and noninvasive diagnosis by 3-Dimension chest CT is easily made for infant with aberrant right subclavian artery.

A 30-year-old male with a symptomatic aberrant right subclavian artery underwent surgical intervention on January 17, 1990. An aberrant right subclavian artery is a rare congenital anomaly, but it is the most common one of the aortic arch anomalies. This anomalous vessel usually does not produce symptoms, but occasionally symptomatic patients require surgical intervention. Although ligation and division of the aberrant right subclavian artery through left thoracotomy has been advocated by many surgeons, the ischemic symptoms of the upper extremity or the brain can occur. In the procedure described here, ligation and division of the aberrant artery and its anastomosis to the ascending aorta with Gore \ulcornerTex vascular graft was performed simultaneously through midsternotomy. With this procedure, we relieved the esophageal obstruction and established normal blood flow to the right arm. Hoarseness developed postoperatively. We consider that above symptom has been attributed to the injury of the left recurrent laryngeal nerve during dissection.

Objective : Aberrant right subclavian artery (ARSA) is a rare anatomical variant of the origin of the right subclavian artery. ARSA is defined as the right subclavian artery originating as the final branch of the aortic arch. The purpose of this study is to determine the prevalence and the anatomy of ARSA evaluated with computed tomography (CT) angiography. Methods : CT angiography was performed in 3460 patients between March 1, 2014 and November 30, 2015 and the results were analyzed. The origin of the ARSA, course of the vessel, possible inadvertent ARSA puncture site during subclavian vein catheterization, Kommerell diverticula, and associated vascular anomalies were evaluated. We used the literature to review the clinical importance of ARSA. Results : Seventeen in 3460 patients had ARSA. All ARSAs in 17 patients originated from the posterior aspect of the aortic arch and traveled along a retroesophageal course to the right thoracic outlet. All 17 ARSAs were located in the anterior portion from first to fourth thoracic vertebral bodies and were located near the right subclavian vein at the medial third of the clavicle. Only one of 17 patients presented with dysphagia. Conclusion : It is important to be aware ARSA before surgical approaches to upper thoracic vertebrae in order to avoid complications and effect proper treatment. In patients with a known ARSA, a right transradial approach for aortography or cerebral angiography should be changed to a left radial artery or transfemoral approach.

A 6-month-old, female poodle presented with a three-month history of persistent regurgitation immediately after eating. On physical examination, the patient was emaciated and dehydrated. Thoracic radiography showed ventral displacement of the trachea and increased radiopacity in the mediastinum, cranial to the heart base. A severely dilated esophagus was identified cranial to the heart on esophagram. Computed tomography (CT) revealed the esophagus was filled with gas, fluid and a little of contrast and dilated from caudo-cervical to cranio-thoracic part. The esophageal diameter was markedly decreased at the heart base. In addition, the trachea was displaced to the left-ventral side of the right aortic trunk and an aberrant left subclavian artery originating from the aorta was identified. There was no evidence of abdominal vascular anomaly. Based on diagnostic imaging, persistent right aortic arch (PRAA) with an aberrant left subclavian artery was diagnosed. The patient did not undergo surgery and died at 15 days after diagnosis. This report describes imaging diagnosis, including CT and radiography in a weaned dog with regurgitation due to esophageal obstruction by PRAA. When PRAA is suspected and conventional radiography or contrast study is insufficient for diagnosis, CT may be helpful for diagnosing PRAA.

이상우쇄골하동맥은 약 0.5～2%에서 발생하며, 성인의 경우 대부분이 임상적인 증상 없이 생활하나 약 10%에서 기관이나 식도의 압박에 의한 임상증상을 나타내는 것으로 알려져 있다. 본 증례는 수년간 연하곤란 및 반복되는 폐렴을 주소로 한 이상우쇄골하동맥을 가진 64세 여자 환자를 보고한다. 혈관 촬영상 좌우 경동맥(carotid artery)이 하나의 동맥간(common trunk)에서 기시하고 우측 쇄골하동맥은 좌측 쇄골하동맥 기시부 가까이의 상행대동맥 후방에서 기시하여 식도의 후방으로 주행하는 이상 우쇄골하동맥을 진단하였다. 수술적 치료는 우측 개흉술을 통하여 이루어졌다. 식도의 후방부위를 박리하여 이상우쇄골하동맥을 완전히 박리하여 유동시켰다. 우쇄골하동맥을 박리한 후 근위부를 결찰하여 분리한 후 원위부를 인조혈관을 이용하여 대동맥 근위부와 연결하였다.

혈관륜이 있는 경우 드물게 동맥 식도루가 발생하여 대출혈이 발생할 수 있다. 42세 남자환자가 교통사고 후 7주간 비위관을 삽입하고 있던 중 상부 위장관 출혈이 발생하여 응급수술을 하였다. 수술 소견상 우측 쇄골하동맥 기시이상이 있었으며 오랜 비위관 상관으로 발생된 것으로 생각되는 동맥-식도루가 있어 이를 수술교정 하였다. 술후 환자상태는 안정 되었으나 술후 5일째 흉관 자극과 염증에 기인 하는 대동맥 봉합부위의 출혈이 발생하여 재수술을 하였고 의식불명 상태로 술후 8일째 사망하였다.

The case of a 40-year-old male with symptom related to a anomalous right subclavian artery [dysphagia lusorium] combined with thymoma is described. He was treated by removal of the thymoma and resection of the retroesophageal right subclavian artery with anastomosis of its distal end to the ascending aortic arch by Gore-Tex. This procedure relieved the dysphagia and provided the right arm with normal arterial circulation.
