Accidental central venous catheter cannulation into aberrant arterial anatomy requiring endovascular intervention

Journal of Vascular Surgery Cases and Innovative Techniques, 2023
Central venous catheter placement continues to be an extremely common procedure throughout hospital systems. Although ultrasound guidance can mitigate some placement risks, misplacement of lines into neighboring structures, such as arteries, remains an ...

Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

The Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

Hybrid repair of an aberrant right subclavian artery with Kommerell's diverticulum

, 2010
This publication describes a hybrid endovascular and open surgical approach to treating a large aneurysm of an aberrant right subclavian artery (Kommerell’s diverticulum). A 76-year old man presented with dysphagia lusoria due to a 3.5 x 3.0 cm aneurysm

Preclinical 1H MRS Study of a Porcine Model Shows Evidence and Mechanisms for Acute Neuronal Injury in Neonatal Cardiopulmonary Bypass (CPB) Surgery

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 557-567, August 2026.
ABSTRACT Purpose Congenital heart disease affects 1% of US births, with some infants requiring cardiothoracic surgery under cardiopulmonary bypass (CPB). Optimal surgical parameters to minimize neuronal injury are unknown. We used serial 1H MRS in a neonatal CPB porcine model to assess acute neuronal damage and associated injury mechanisms.

Malposition of a Port Catheter in the Azygos Vein: Endovascular Repositioning Using a Long Loop Snare Technique

Catheterization and Cardiovascular Interventions, Volume 108, Issue 1, Page 33-35, July 1, 2026.
ABSTRACT Port catheters provide a reliable, long‐term venous access option in children for repeated administration of medications or parenteral nutrition. A cardiac catheterization procedure was performed in a 7‐year‐old girl in whom lateral chest radiography revealed posterior deviation suggestive of azygos vein malposition.

Hybrid repair of Kommerell's diverticulum with aberrant subclavian artery

Journal of Vascular Surgery Cases and Innovative Techniques
Kommerell's diverticulum (KD) is a rare aortic arch anomaly associated with aberrant subclavian arteries and risk of rupture. We present an 80-year-old woman with a right-sided aortic arch and aberrant left subclavian artery arising from a 5.0-cm KD.

Right Sided Aortic Arch and its Rare Associations- A Case Series

International Journal of Anatomy Radiology and Surgery, 2018
Right sided aortic arch is a rare incidental anomaly in adults often asymptomatic. Most common subtype is Right Aortic Arch (RAA) with aberrant left subclavian artery. We report three cases of right sided aortic arch with multiple vascular anomalies. Two

Central Venous Pressure Referencing in the Lateral Position: Comparison With Direct Right Atrial Pressure in Mechanically Ventilated ICU Patients

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 6, July 2026.
ABSTRACT Background Right atrial pressure (RAP) is a key determinant of venous return and reflects right‐sided filling pressures in critically ill patients. Central venous pressure (CVP) is commonly used as a surrogate, but its accuracy depends on appropriate transducer levelling. While reference points have been evaluated in supine positions, evidence

Structural aortic arch shift and supraaortic angle configuration changes after subclavian to carotid transposition as a proposed mechanism for relief of severe esophageal compression in aberrant subclavian artery anatomy

Annals of Vascular Surgery - Brief Reports and Innovations
Objective: – Adult patients with a right-sided aortic arch and aberrant left subclavian artery with a co-existing Kommerell’s diverticulum (KD) can develop clinically significant esophageal compression requiring staged, open, followed by endovascular ...
