Objective: Rare disease Background: Kommerell diverticulum with a right-sided aortic arch is a rare congenital anatomical condition most often observed in adults. A possible etiology of the subclavian artery's anomalous origin would be an abnormality in regression of the fourth primitive aortic arch during embryonic development. Case Report: We report on the case of a 16-year-old female patient presenting with complaints of occasional tachycardia and mild non-specific dyspnea after anxiety crises. Physical examination revealed lower amplitude of the pulses in the left upper limb compared to the right upper limb, and difference in blood pressure (BP) values of 80×60 mmHg, and 100×60 mmHg, respectively. Different radiological imaging modalities were performed to elucidate a possible vascular abnormality. Multislice detector computed tomography angiography of the thoracic aorta and supra-aortic trunks showed a right-sided aortic arch and an aberrant origin of the left subclavian artery with a retroesophageal course and dilation of its emergence (Kommerell diverticulum), as well as duplicity of the right vertebral artery (RVA). Considering the actual small diameter of the diverticulum and the absence of dysphagia or severe external esophageal compression analyzed by the esophagogram, vascular surgery was not indicated. Since complications have been described in the literature, the patient must be kept under observation in the future. Conclusions: Congenital vascular alterations, including Kommerell diverticulum with right-sided aortic arch and the aberrant origin of the left subclavian artery, should be suspected in otherwise asymptomatic young patients with few clinical manifestations. Investigation with different imaging methods helps to clarify the vascular abnormalities, to support a possible surgical procedure indication, and to monitor the patients in follow-up.

Kommerell's diverticulum is an aortic arch deformity associated with an aberrant subclavian artery. Symptoms related to compression of adjacent structures, dilatation of the aortic diverticulum or accelerated atherosclerosis leading to increased risks of dissection and rupture represent the indications for surgical treatment. Several surgical strategies have been used for the management of this congenital abnormality. We present the case of a 56-year-old male with a pseudo-aneurysm of a left aortic arch adjacent to a Kommerell's diverticulum at the orifice of a left subclavian artery. The patient also presented an aberrant right subclavian artery originating from the posterior wall of the ecstatic take-off of the left subclavian artery. Our surgical strategy was limited to the resection of the aneurysm without any manipulation of the aortic diverticulum and aberrant right subclavian artery, as the wall of both aorta adjacent to the saccular aneurysm and left subclavian artery was normal, the Kommerell's diverticulum was small and the patient was asymptomatic.

Background: Kommerell’s diverticulum is a rare vascular anomaly characterized as an outpouch at the onset of an aberrant subclavian artery. In the variant of a right-sided aortic arch, the trachea and esophagus are enclosed dorsally by the arch. In the configuration of an aberrant left subclavian artery, a Kommerell’s diverticulum and persisting ductus arteriosus or ductal ligament enclose the lateral side, forming a vascular ring which may result in (symptomatic) esophageal or tracheal compression. Spontaneous rupture of an aneurysmatic Kommerell’s diverticulum has also been reported. Due to the rarity of this condition and underreporting in the literature, the clinical implications of a Kommerell’s diverticulum are not well defined. Case summary: We describe seven consecutive adult patients with a right-sided aortic arch and an aberrant course of the left subclavian artery (arteria lusoria), and a Kommerell’s diverticulum, diagnosed in our tertiary hospital. One patient had severe...

A right-sided aortic arch is an anatomic variant occurring in approximately 0.1% of the population, 1 and in half of these cases the left subclavian artery is also aberrant. 2,3 These anomalies may be isolated or occur in combination with congenital heart defects. We conducted a review of the literature and report one case of a Kommerell's diverticulum of an aberrant left subclavian artery in a patient with a right-sided aortic arch and a descending thoracic aortic aneurysm.

Congenital variations and anomalies of the aortic arch are important entity in vascular imaging. Most of them are asymptomatic. About 30-40% presents with tracheo-oesophageal symptoms like dyspnea and dysphagia. A 27 year-old female presented with persistent dysphagia for 6 months duration and cause of persistent dysphagia was the right sided aortic arch with aberrant left subcalvian artery from Kommerell’s diverticulum. The diagnosis was made through combination of chest X-Ray, echocardiography, non-ionic contrast swallow and Computed Tomography angiography. Non-invasive modalities (CT and MR Angiography) play an important role in diagnosis and pre-operative surgical planning providing relationship with the surrounding structures especially trachea and esophagus.
Kommerell's diverticulum and right-sided aortic arch: a cohort study and review of the literature
Journal of Vascular Surgery, 2004
We report four consecutive cases of Kommerell's aneurysm of an aberrant left subclavian artery in patients with a right-sided aortic arch and the results of a systematic review of the literature. In our cohort of patients, three had an aneurysm limited to the origin of the aberrant subclavian artery, causing dysphagia and cough, and one had an aneurysm involving also the distal arch and the entire descending thoracic aorta, causing compression of the right main-stem bronchus. A left subclavian-to-carotid transposition was performed in association with the intrathoracic procedure, and a right thoracotomy was used in all patients. One of the patients underwent surgery with deep hypothermia and circulatory arrest, and the others with the adjunct of a left-heart bypass. The repair was accomplished with an interposition graft in two patients and with endoaneurysmorrhaphy in the others. The postoperative course was complicated by respiratory failure and prolonged ventilation in one patient, and one patient died because of severe pulmonary emboli. The survivors are alive and well at a follow-up of 1 to 3 years. Only 32 cases of right-sided aortic arch with an aneurysm of the aberrant subclavian artery have been reported: 12 were associated with aortic dissection, and 2 presented with rupture. Surgical repair was accomplished in 29 patients. A number of operative strategies were described: right thoracotomy, bilateral thoracotomy, left thoracotomy with sternotomy, sternotomy with right thoracotomy, and left thoracotomy. In only 12 cases was the subclavian artery reconstructed. We believe that a right thoracotomy provides good exposure and avoids the morbidity associated with bilateral thoracotomy or sternotomy and thoracotomy. We feel that a left subclavian-to-carotid transposition completed before the thoracic approach revascularizes the subclavian distribution without increasing the complexity of the intrathoracic procedure.

Aberrant Subclavian Artery (ASA) is a rare anomaly within the aortic arch. In some cases, an aneurysm can also develop in the proximal ostium of the ASA which is called Kommerell diverticulum. In this article we report two symptomatic patients with a rare anatomical anomaly caused by a right sided aortic arch and left aberrant subclavian artery with Kommerell diverticulum causing dysphagia lusoria. In the first patient with hemoptysis we conducted surgical excision of the left subclavian artery origin along with bypass end-to-side bypass grafting. In the second patient we transected and ligated the left subclavian artery and with an end-to-side bypass transposition graft, followed by thoracic endovascular repair with simultaneous coil embolization of the Kommerell diverticulum.
