Tuberculous Subclavian Artery Pseudoaneurysm in a Young Male With Hemoptysis.

Vascular Surgery, Unidade Local de Saúde São José, Lisbon, PRT.
Subclavian artery pseudoaneurysms (SAPs) are rare and most often secondary to trauma. On the contrary, a mycotic origin is exceedingly rare, and defining this etiology can become challenging. We present a rare case of a tuberculous SAP in a young patient.

Background: The sympathetic autonomic nervous system plays a major role in arrhythmia development and maintenance. Historical preclinical studies describe preferential increases in cardiac sympathetic tone upon selective stimulation of the subclavian ansae (SA), a nerve cord encircling the subclavian artery.
Objectives: This study sought to define, for the first time, the functional anatomy and physiology of the SA in humans using a percutaneous approach.
Comprehensive Analysis of Neurologic Complications Following Transradial Cerebral Angiography.
AJNR Am J Neuroradiol
December 2024
From the Department of Neurosurgery, Bucheon St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea.
Background And Purpose: Transradial access (TRA) for cerebral angiography has become more popular due to fewer complications and greater patient comfort compared to transfemoral access. However, the frequency and nature of neurologic complications linked to TRA remain unclear. This study aimed to determine the incidence of symptomatic neurologic complications after transradial cerebral angiography, identify risk factors, and characterize clinical and imaging features of these complications.

Department of Medical Imaging, Jewish General Hospital.
Objective: Fluorodeoxyglucose PET/computed tomography (FDG PET/CT) is effective in detecting large vessel vasculitis. Digital PET cameras have improved spatial resolution compared with analog PET, resulting in more prominent physiological uptake in arterial walls. This study's goal was to define qualitative normal variants of arterial activity on digital PET/CT.

Vasculitis is an autoimmune disease defined by inflammation within blood vessels, typically manifesting systemically with multi-organ complications and clinical features. Isolated vasculitis itself, however, is extremely rare and not characteristically based on the pathophysiology of the condition. Whilst there have been cases of isolated vasculitis in large-medium vessels (e.
