Background: Radial loops are rare congenital radial artery anomalies that may pose a significant challenge to successful transradial neuroangiography. In this case series, we describe the anatomy and frequency of radial artery loops and provide a technique for successful navigation of this anatomic anomaly.
Methods: We reviewed our database of radial diagnostic or interventional neuroangiographic procedures to identify cases in which a radial loop was encountered during the procedure. The loop pattern, the presence of an associated recurrent radial artery branch, navigation technique, and procedure-related complications were recorded. A descriptive analysis was performed.
Results: A total of 997 transradial approach procedures were performed over a 9-month period. A radial loop was identified in 10 (1.0%) patients. The average age was 68.6 ± 14.3 years. A microcatheter advanced over a microwire was used to navigate the loop and avoid entry into the recurrent branch. A diagnostic neuroangiographic procedure was performed successfully in 8 cases and an intervention was performed successfully in 1 case. A 360° loop was present in 2 of these cases. In each case, transradial access was performed successfully. In 1 other diagnostic case, transradial access was aborted, and the femoral artery was accessed to perform the procedure.
Conclusions: A radial loop was present in 1% of the cases in this series. Our technical results suggest that this anomaly should not be considered a contraindication to transradial neuroangiography because the procedure was successfully performed in most (9 of 10) cases using a microcatheter system to navigate the loop.

This study aimed to analyze the clinical characteristics and prognosis of Takayasu's arteritis (TA) with carotid artery occlusion in children. This study collected clinical data and follow-up information on the first diagnosis and treatment of c-TA combined with carotid artery occlusion in pediatric patients at the Children's Hospital affiliated with the Capital Institute of Pediatrics and Inner Mongolia Medical University Affiliated Hospital from 2013 to 2023. This study included four female patients with a mean age of (13.

Background: Radial artery cannulation can be challenging, particularly for inexperienced providers. This study aimed to compare the success rates of resident physicians performing radial artery cannulation with mild sedation and analgesia versus without.
Materials And Methods: This study was a prospective, single-center, double-blind randomized controlled trial.

The Pulse Index Contour Continuous Cardiac Output (PICCO) module provides advanced and continuous monitoring of cardiac output through the use of arterial pulse contour analysis and transpulmonary thermodilution. The objective of this study was to compare the early postoperative outcomes of patients who were monitored using the conventional method and the pulse contour analysis method. A prospective observational study was conducted involving 45 patients who underwent cardiac surgery between 2020 and 2022.

Femoral artery closure devices are used to shorten vascular closure time and reduce bleeding. We sought to examine sex-based outcomes of femoral artery vascular closure devices (VCD) in patients undergoing PCI.

Background: Small fetuses include constitutional small for gestational age (SGA) and fetal growth-restricted (FGR) fetuses. Various adverse intrauterine environments can lead to FGR which has higher risk of abnormal perinatal outcome. The fetal heart is very sensitive to the effects of a negative intrauterine environment.
