Unlabelled: PurposeThe aim of the study was to perform CT angiography-based evaluation of aberrant right subclavian artery prevalence, anatomy, and its influence on clinical symptoms.

Methods: A total of 6833 patients who underwent 64-slice or dual-source CT angiography and those who revealed aberrant right subclavian artery underwent evaluation of its anatomy and were interviewed for the presence of clinical symptoms.

Results: Aberrant right subclavian artery was found in 32 (0.47%) patients consisting of 13 males and 19 females, with mean age of 60.8±13.4 years. Among the interviewed 30 (94%) patients, oesophageal compression was observed in 14 cases (47%) and tracheal compression in three cases (10%). None of the patients underwent surgery related to aberrant right subclavian artery. Dysphagia was the most common clinical symptom in nine cases (30%), and in those patients the median distance between aberrant right subclavian artery and trachea was lower (4 mm) than in individuals without dysphagia (7.5 mm) (p = 0.009). The median lumen area of the aberrant right subclavian artery at the level of oesophagus was higher in patients with dysphagia (208 mm2) compared with individuals without dysphagia (108 mm2) (p = 0.01).

Conclusions: Aberrant right subclavian artery is a rare occurring abnormality in CT angiography. In the evaluated adult population, the most common symptom was dysphagia, which occurred in patients with decreased distance between aberrant right subclavian artery and trachea and increased lumen area of the aberrant artery at the level of compressed oesophagus.

Background: The optimal treatment of complicated type B aortic dissection (cTBAD) involving arch anomalies remain unclear.

Methods: We consecutively enrolled patients with cTBAD involving arch anomalies who underwent endovascular repair using a single-branched stent graft (SBSG) at our medical center between January 2020 and January 2023. The demographics, clinical manifestation, operation detail, and follow-up outcomes of these patients were retrospectively collected and analyzed.

Analysis of associated malformations by computed tomography in adults with polysplenia syndrome: A pilot study.

PLoS One

December 2024

Department of Medical Imaging, The Affiliated Suzhou Hospital of Nanjing Medical University, Gusu School of Nanjing Medical University, Suzhou, Jiangsu, China.

Objective: To analytically depict the associated malformations of polysplenia syndrome (PS) in adults via computed tomography (CT).

Materials And Methods: The incidence of malformations associated with PS in twelve adult patients was retrospectively analyzed via CT imaging.

Results: The number of splenic nodules ranged from three to twelve; the splenic nodules were located in the left upper quadrant in nine patients and in the right upper quadrant in three patients.

Dysphagia lusoria is a rare condition characterized by swallowing difficulties due to vascular compression of the esophagus. While most commonly caused by an aberrant right subclavian artery (ARSA), other vascular anomalies can also lead to this condition. We present a unique case of dysphagia lusoria in a 20-year-old Ethiopian male, caused by a vertebral artery originating anomalously from the aortic arch.

Objectives: This study aimed to evaluate the association of aberrant right subclavian artery (ARSA) with genetic abnormalities and postnatal symptomatology, by comparing isolated and non-isolated ARSA cases.

Methods: Retrospective, descriptive and comparative study involving fetuses diagnosed with ARSA during routine fetal ultrasound scans, between 19 and 40 weeks, in a tertiary referral university hospital in Barcelona from January 2007 to December 2023.

Results: Out of 154 fetuses diagnosed with ARSA, 75.
