Polysplenia syndrome is a rare condition (about 2.5:100,000 live births) wherein a person has two or more spleens with accompanying various thoracic and abdominal organ abnormalities. Polysplenia is usually associated with situs ambiguous, while polysplenia with situs inversus is very rare. Herein, we report a rare case of incidentally found polysplenia syndrome combined with situs inversus in a 59-year-old female who also had an interrupted inferior vena cava (IVC) with azygos continuation, patent ductus arteriosus (PDA), and variations in the aortic arch branches...

Several congenital anomalies regarding the right (RVA) and left (LVA) vertebral artery have been described. The current paper aims to perform a systematic literature review of the variable vertebral artery (VA) origin from the aortic arch (AOA) and its branches. The incidence of these variants and the ensuing AOA branching pattern are highlighted. Atypical origin cases were found more commonly unilaterally, while LVA presented the majority of the aberrancies. The LVA emersion from the AOA (3.6%) and the RVA from the right common carotid artery (RCCA) (0...

A double left brachiocephalic vein is an uncommon anatomic variation. Among these, a accessory branch with preaortic course is extremely rare. In this case, both branches of the left brachiocephalic vein were anterior to the aortic arch. We describe the computed tomography findings with volume-rendering imaging of this rare anatomic variation.

AIM: The aim of this study is to investigate the incidence of variation in the branching pattern of aortic arch (AA) vessels in an Irish population. METHOD: A cadaveric study of 24 subjects was conducted. The vessels of the AA were identified, their branching patterns were noted and photographed and the following measurements were recorded: the angle of the AA to the coronal plane, the distance from the midline to the brachiocephalic trunk (BCT); the left common carotid artery (LCC) ; the left subclavian artery (LSC), the distance between the BCT and the right subclavian artery (RSC); the RSC and the right vertebral artery (RVA), and between the LSC and left vertebral artery (LVA)...

Here, we present a unique case with 5 branches of the aortic arch (AA), namely the right common carotid artery, left common carotid artery, left thyrocervical trunk, left subclavian artery and right subclavian artery (RSA), from right to left. We found that the left thyrocervical trunk originated directly from the AA rather than the left subclavian artery. In addition, the RSA arose dorsally as the last branch of the AA and passed posteriorly to the oesophagus to supply the right upper limb. In addition, the right vertebral artery originated from the right common carotid artery instead of the RSA...

OBJECTIVE: The aortic arch (AA) is the main conduit of the left side of the heart, providing a blood supply to the head, neck, and upper limbs. As it travels through the thorax, the pattern in which it gives off the branches to supply these structures can vary. Variations of these branching patterns have been studied; however, a study providing a comprehensive incidence of these variations has not yet been conducted. The objective of this study was to perform a meta-analysis of all the studies that report prevalence data on AA variants and to provide incidence data on the most common variants...

Variations in the origins and the branching pattern of the carotid system of arteries are not uncommon. Here we report a rare case of higher bifurcation of the common carotid artery (CCA) (at the level of the greater cornu of the hyoid bone), thyrolinguofacial trunk (TLFT) originating from the CCA, superior laryngeal artery (SLA) arising from the external carotid artery (ECA) on the left side, and linguofacial trunk arising from the ECA on the right side. In the present case, the CCA and carotid bifurcation may have arisen from the second aortic arch...

Donkeys are a member of the horse family (Equidae) and share a common ancestor. However, in morphological terms, donkeys and horses are regarded as two separate subgenus. Given variations in the branching pattern of the brachiocephalic trunk (BCT) in different species of animals and the use of donkeys in anatomy courses at colleges of veterinary medicine, we conducted this study in order to investigate the branching patterns of BCT and to describe detailed morphological information regarding donkeys. Seventeen mature donkeys were examined following euthanasia by exsanguination from the common carotid artery under general anaesthesia...

BACKGROUND: Reconstruction of the aortic major branches during thoracic endovascular aortic repair is complicated because of the complex anatomic configuration and variation of the aortic arch. In situ laser fenestration has shown great potential for the revascularization of aortic branches. This study aims to evaluate the feasibility, effectiveness, and safety of in situ laser fenestration on the three branches of the aortic arch during thoracic endovascular aortic repair. METHODS AND RESULTS: Before clinical application, the polytetrafluoroethylene and Dacron grafts were fenestrated by an 810-nm laser system ex vivo, which did not damage the bare metal portion of the endografts and created a clean fenestration while maintaining the integrity of the endografts...

Tracheostomy is a common procedure in head and neck surgery and emergency medicine to secure a patent airway. Surgeons should always be aware of anatomical variants of the branches of the aortic arch, which could lead to life-threatening complications. Open tracheostomy is the safest emergency procedure.

Internal thoracic and inferior thyroid arteries mainly supply the thymus. However, very few studies have been reported on the arterial variations of the thymus. The first author, a cardiac surgeon, happened upon a thymic artery arising from either proximal aortic arch or distal ascending aorta in a few cases during routine cardiac surgery in infants and neonates. Hence a study on the prevalence of the variant thymic artery during open heart surgery was contemplated, as knowledge of its presence could avoid its injury during surgical and diagnostic procedures of the region...
