The cisterna chyli, a dilated lymphatic sac in the retrocrural space, is usually located to the right of the aorta. We report a case of a left-sided cisterna chyli, which was incidentally detected on the radiologic examinations of a preoperative workup for cholangiocarcinoma. Computed tomography (CT) and magnetic resonance (MR) images revealed a cisterna chyli measuring 2.5 cm in length in the left retrocrural space. The dilated lumbar lymphatics joined with the cisterna chyli, which was continuous with the left-sided thoracic duct. To the best of our knowledge, this is the second antemortem case of a left-sided cisterna chyli in literature. The cisterna chyli can mimic retrocrural lymphadenopathy, solid tumor with cystic degeneration, abscess or hematoma. The left-sided cisterna chyli should be referred to as a structure so as to be cautious in surgical approach.

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.

We present an unusual case of vascular sling, tracheal stenosis by complete cartilaginous ring, and aberrant left subclavian artery with right aortic arch that underwent successful surgical repair for the sling. These abnormalities were suspected from unusual multiple indentations found on esophagogram. Complete preoperative diagnosis was established with chest computerized tomogram combined with angiography.

This report describes coexistence of anomalous branches of the aortic arch and the costocervical vein malformation in a German shepherd dog. The first branch of the aortic arch was a bicarotid trunk that divided into the left and right common carotid arteries. The next branch to leave the aortic arch was a common trunk for the right and left subclavian arteries, a bisubclavian trunk, which was immediately bifurcated. The right subclavian artery passed over the esophagus forming a deep groove, so-called incomplete vascular ring on the dorsal wall of the esophagus. Although the esophagus was constricted by the right subclavian artery dorsally and by the trachea ventrally, no clinical symptoms of esophageal obstruction and dysphagia were observed. The left costocervical vein coursed caudoventrally, passed over the aortic arch, and entered the left ventricle. This vessel was much smaller than the right costocervical vein and was partially occluded at its origin.

An aberrant right subclavian artery (ARSA) is the most common vascular abnormality of the aortic arch and is associated with development of aneurysms in 3-8% of these anomalies. In this case report, we describe an 84-year-old man with a symptomatic ARSA treated with staged hybrid procedure combining surgical replacement of the ascending aorta and bilateral carotid-to-subclavian artery bypass with implantation of a stent graft in the aortic arch and descending aorta. Our case suggests that a less invasive hybrid therapy can be performed successfully for the treatment of ARSA with aneurysmal change in patients at high surgical risk.

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.
