CT Angiography of the Upper Extremities: Review of Acute Arterial Entities.
Radiographics
January 2025
From the Mallinckrodt Institute of Radiology, Washington University in St. Louis School of Medicine, 510 S Kingshighway Blvd, St. Louis, MO 63110.
Historically, evaluation of the upper extremity vasculature was performed using digital subtraction angiography. With the advancement of cross-sectional imaging and submillimeter isotropic data acquisition, CT angiography (CTA) has become an excellent noninvasive diagnostic tool for evaluation of the vasculature of the upper extremities. CTA allows quick evaluation of vessel patency and irregularity and achievement of the anatomic detail needed in preoperative planning.

Background: Sutural anatomy variation has long been a topic of debate among anatomists, paleontologists, and morphologists. While the exact reasons for the prevalence of this variance remains a topic of ongoing discussion, developmental and genetic factors are hypothesized to be the main reasons. Understanding the morphology and occurrence of normal sutural variations in pediatric patients is essential to making the right diagnosis, where a misinterpretation of a sutural bone may lead to an inaccurate assessment, completely misleading the diagnostic process.

Objective: Diffuse coronary artery disease remains a critical issue that heart surgeons continue to research in terms of treatment options. An alternative method applied during coronary bypass surgery to achieve complete revascularization is coronary artery endarterectomy. Since the reliability of this technique and its effects on mortality and morbidity are still debated in the literature.

Department of Radiology, Kanazawa University Graduate School of Medical Sciences, 13-1 Takara-Machi, Kanazawa, 920-8641, Japan.
Background: The effect of vessel morphology on the technical success and patency of Viabahn stent-grafts in treating postoperative arterial injuries and bleeding (AIB) after hepatopancreatobiliary surgery is not well understood. Difficulties in stent insertion persist despite using stiff guidewires to straighten tortuous vessels. This study aimed to identify vessel morphologies linked to technical success and short-term patency and to explore effective management strategies.

A functional vascular access (VA) is of paramount importance to patients on hemodialysis therapy. While arteriovenous fistula (AVF) remains the preferred VA, their long-term patency is unpredictable. A dysfunctional VA contributes to a high morbidity rate, an increased susceptibility to major adverse cardiovascular events, recurrent hospitalization, and a poor quality of life.
