This study aimed to investigate the prevalence of persistent trigeminal arteries (PTAs) using computed tomography (CT) angiography, emphasize its major characteristics, and compare the ndings with those reported in the relevant literature. MethodsPatients who underwent cerebral CT angiography in our radiology clinic for any preliminary diagnosis between December 2013 and December 2020 were included in this retrospective study. The patients were reviewed in terms of their age, sex, and the presence of PTAs. The localization of the PTA, vascular connection, PTA type (according to Saltzman and Salas classi cation), and vascular pathology at the level of anastomoses were examined in the patients with PTAs. ResultsA total of 1150 patients, (632 [55%] males and 518 [45%] females) were included in this study. A total of seven (0.6%) patients had PTAs. PTAs were located on the right and left sides in 3 (43%) and 4 (57%) patients, respectively. A total of 3 (43%), 2 (28%), and 2 (28%) cases were classi ed as types I, II, and III PTA based on the Saltzman classi cation, respectively. Moreover, 4 (57%) and 3 (43%) cases were lateral and medial types based on the Salas classi cation, respectively. ConclusionIn conclusion, understanding the diagnosis and classi cation of PTAs is crucial for the diagnosis of possible vascular pathologies by neuroradiologists and physicians performing neurovascular interventional procedures or operations. If these vascular pathologies remain undetected, they may cause fatal bleeding or embolism during surgeries and endovascular procedures.

A previously healthy 12-year-old girl presented to the emergency department with severe chest pain and dyspnea that woke her from sleep. She had short-term syncope just before the emergency admission. On physical examination, respiratory rate was 26 breaths per minute while resting, and blood pressure was 92/56 mmHg. Other physical examination findings were insignificant. She had no past medical history, and her family history was unremarkable. Laboratory test results showed elevated C-reactive protein (27 mg/L; reference range: <5 mg/L) and white blood cell count (13.7 K/μL; reference range: 4-12 K/μL).Other laboratory test results were within normal limits, including troponin T value
