ABSTRACT
Case 1 is a 70-year-old male. He has a history of cholelithiasis and left inguinal hernia. A preoperative examination of the inguinal hernia showed the enlargement of the mediastinal shadow, and he was referred to our department. A close examination revealed a right-sided aortic arch, a right descending aorta, and a descending aortic diverticulum. No subjective symptoms, intracardiac malformations, or other cardiovascular diseases were observed. The surgery was scheduled for descending aorta replacement including a diverticulum with right posterior lateral 4th intercostal thoracotomy and lower body partial extracorporeal circulation. However, due to aortic intima injury at the proximal end, hypothermic cerebral circulatory arrest and proximal anastomosis were performed by the open proximal method. There was no problem with the postoperative course, and he was discharged 19 days after surgery. Case 2 is a 51-year-old female. Born in China, she has lived in Japan for 15 years. No notable history. An abnormal shadow was shown on chest Xp performed in a medical examination, and aortic malformation was suspected on chest CT. She was referred to our department. The diagnosis was right-sided aortic arch, right descending aorta, aberrant left subclavian artery, and Kommerell diverticulum. There were no subjective symptoms and no intracardiac malformations. The operation was a two-stage operation. As the initial surgery, median sternotomy was performed, total arch replacement with intrathoracic reconstruction of the left subclavian artery, and open stent graft insertion, and the Kommerell diverticulum was covered with an open stent graft. We did not treat the diverticulum because it was located on the dorsal side. At 15 days after surgery, we performed embolization of the origin of the left subclavian artery from the Kommerell diverticulum. There was no problem with the postoperative course, and she was discharged 19 days after the initial surgery.
ABSTRACT
We report a case of debranching thoracic endovascular aortic repair for Kommerell's diverticulum with right-sided aortic arch in 78-year-old women. The computed tomography (CT) demonstrated Kommerell's diverticulum with a right-sided aortic arch and the trachea and esophagus were compressed by the diverticulum. The diverticulum had a maximum diameter of 32 mm, and surgical intervention was chosen because of the aneurysmal change and the possibility of rupture. We performed endovascular aortic repair for Kommerell's diverticulum with a right-sided aortic arch because of low lung function and low frailty. The patient was discharged on the 21st postoperative day. There was no evidence of aortic event during 2 years follow up.
ABSTRACT
The patient was a 73-year-old man who was referred to our hospital due to an abnormal thoracic shadow. CT scans revealed Kommerell's diverticulum and saccular aortic arch aneurysm accompanied by abnormal origins of the right aortic arch and the left subclavian artery. Although there were no subjective symptoms, a surgical operation was planned considering the risk of a rupture of the saccular aneurysm. For the surgery, a median sternotomy approach was employed. Under cardiopulmonary bypass, the aortic arch was detached using the open distal method. Further, an open stent graft was inserted, and the aortic arch was replaced with a four-branched artificial blood vessel. After weaning off the cardiopulmonary bypass, coil embolization was performed on the left subclavian artery, and the site was checked to ensure that there was no endoleak. Although hoarseness was noted postoperatively due to paralysis of the right vocal cord, the patient progressed without any other major complications and was discharged 30 days after the operation.
ABSTRACT
A 69-year-old man with type II right-sided aortic arch (RAA) underwent an off-pump coronary artery bypass grafting (OPCAB) in December, 2017. He underwent an abdominal aortic aneurysm resection and graft replacement in April, 2018. The postoperative computed tomography (CT) that was performed in May 2018 revealed aortic dissection from the ascending aorta to the aortic arch, although he was asymptomatic. We evaluated the native coronary artery and patent bypass grafts by coronary CT. Graft replacement of the ascending aorta and partial aortic arch was carried out on an elective basis and the proximal anastomotic site of the vein grafts was attached to the prosthetic graft. Stanford type A aortic dissection (AAD) after previous coronary artery bypass grafting differs from spontaneous AAD in presentation, management and outcome. We report here a successful surgical case with RAA and AAD after OPCAB.
ABSTRACT
Vascular rings which can cause symptoms related the trachea and esophagus compression occur in less than 1% of all cardiovascular malformations. Double incomplete aortic arch with right-sided aorta and aberrant left subclavian artery is the rarest one, and its present in 0.04-0.1% of autopsy series. A case of this malformation with a Kommerell's Diverticulum is presented. This diverticulum has risk of severe complications such as dissection and/or rupture.
Los anillos vasculares pueden causar síntomas relacionados a compresión de tráquea y esófago y ocurren en menos del 1% de todas las malformaciones cardiovasculares. El doble arco aórtico incompleto con arco aórtico a la derecha y arteria subclavia izquierda aberrante es la forma más rara y se presenta en el 0.04 a 0.1% de las series de autopsia. Se presenta un caso de esta malformación con un divertículo de Kommerell. El divertículo tiene riesgo de complicaciones severas como disección y/o ruptura.

Aim: We reported a rare case of an anomalous origin of the left pulmonary artery (AOLPA) from the ascending aorta associated with pulmonary atresia and right sided aortic arch diagnosed at a relatively late age. Case: 13 year-old girl presented to our pulmonology clinic with complaints of cough and dyspnea. On chest X-ray cardio thoracic ratio was increased and shadow of the arch was not seen on the left. On her echocardiography pulmonary arteries couldn't be demonstrated. Computed tomography angiography was performed to the patient. Right sided arch aorta with pulmonary atresia associated with an anomalous origin of the left pulmonary artery from the ascending aorta with a well developed collateral blood supply to the right lung and coexisting pulmonary infection was detected. She was managed medically. She is on the first year of her follow up. Her medical status is stable. Conclusion: We presented a case of relatively rarely seen anomalous origin of the left pulmonary artery from the ascending aorta with a rarely seen association of pulmonary atresia and wanted to take attention to its presentation in a late childhood.
ABSTRACT
A 74-year-old woman was referred to our unit with a chief complaint of dysphagia. Enhanced CT showed a Kommerell diverticulum with a maximum diameter of 46 mm, associated with a right-sided aortic arch and aberrant left subclavian artery. We performed two-staged operations : left subclavian-common carotid artery bypass followed by total arch, and descending aortic replacement by an antero-lateral thoracotomy with partial sternotomy (ALPS). The postoperative course was uneventful. Total arch and descending aortic replacement for a Kommerell diverticulum by an ALPS approach is rare. ALPS approach for Kommerell diverticulum achieves safe surgery with good exposure.
ABSTRACT
Kommerell's diverticulum is a rare congenital disorder characterized by typical right sided aortic arch and aberrant left subclavian artery which are usually detected by accident in asymptomatic patients. However, some of patients complain of severe symptoms caused by compression of the adjacent organs or complicated aortic dissection by the diverticulum. Early detection of the disease can lead to elective surgical correction. In this article, we report a Kommerell's diverticulum case initially detected by transesophageal echocardiography.

We present a rare variation of the right-sided aortic arch with the retroesophageal left subclavian artery as the forth branch found in a cadaver of an 89-year-old Korean woman during a routine dissection. In this case, the first branch that arose from the ascending aorta was the left common carotid artery, which crossed ventral to the trachea in a left cephalic direction, followed by the right common carotid artery and then the right subclavian artery. Distal to these branches the aortic arch ran dorsally, passing between the esophagus and the vertebra. The left subclavian artery arose from the descending portion of the aortic arch, crossing over to the left upper extremity behind the esophagus. This anomaly was not accompanied by congenital heart disease. Accurate information regarding this variation is of great importance to surgeons for its early identification and preservation during interventions and to radiologists for precise interpretation of angiograms.

Right sided aortic arch is an uncommon congenital anomaly. It can be classified into three types, depending on the left aortic arch's degenerating pattern and the branching pattern of the great vessels. It can be associated with major congenital heart disease, depending on the type of right sided aortic arch. We report a case of an 18-years-old female who has right sided aortic arch with atrial septal defect (ASD). In our case, the patient had a right sided aortic arch and aberrant left subclavian artery, also she had ASD (ostium secundum) and moderate tricuspid regurgitation with pulmonary hypertension. The patient was successfully performed patch closure of ASD and tricuspid valve annuloplasty via midline sternotomy. The patient had uneventful postoperative course.

A right-sided aortic arch and Kommerell's diverticulum, remnants of the left dorsal aortic arch in the circulation of the embryo, are uncommon congenital defects of the aorta. They may be asymptomatic in most cases, but symptoms are manifested by compressing mediastinal structures or are related to congenital heart anomalies. If aneurismal dilatation of the diverticulum presents with rupture, it is lethal. We report a case of esophageal compression by a right-sided aortic arch and Kommerell's diverticulum that mimicked an esophageal submucosal tumor in a patient who complained of symptoms during the past ten years of food retention in the upper thorax when a bolus of food was ingested.
