AI Article Synopsis
- * A 59-year-old man had a series of TIAs and was diagnosed with idiopathic internal carotid artery (ICA) dissection, which was ultimately linked to his elongated styloid process.
- * After undergoing surgery to remove the elongated styloid process and placing a cervical stent, the patient experienced no further ischemic attacks, indicating a potential solution for similar cases.
Article Abstract
Background: An elongated styloid process is known to cause ischemic stroke. Previous reports claim that internal carotid artery (ICA) dissection due to the elongated styloid process has good outcomes when treated conservatively; however, long-term follow-up has not been attempted and recurrence in the later period has not been reported so far. We report a case of recurrence of symptoms over a decade after the initial onset.
Case Description: A 59-year-old man experienced a transient ischemic attack (TIA) 10 years ago. Six years ago, he experienced hemispheric TIA, and magnetic resonance angiography revealed a diminished signal of the left ICA; however, no further examination was performed. Four years ago, he experienced another transient amaurosis attack and was treated with antiplatelet therapy because no embolic source was detected using ultrasonography examination, and he was diagnosed with idiopathic ICA dissection. Recently, he experienced a third amaurosis fugax attack. Digital subtraction angiography and cone-beam computed tomography demonstrated left cervical ICA dissection due to elongated styloid process. He underwent surgical resection of the left styloid process and cervical stent placement. He had no ischemic attacks postoperatively.
Conclusion: The elongated styloid process may cause recurrent ischemic attacks over a decade due to ICA dissection.

Division of Oral Radiology, School of Dentistry, Federal University of Ceará, Fortaleza, Ceará, Brazil.
Purpose: This study aimed to assess the styloid process (TBSP) phenotype and to identify suggestive images of calcified atheromatous plaques (CAP) in panoramic radiographs of patients with primary hyperparathyroidism (PHPT) and post-surgical hypoparathyroidism (hypoPT). Additionally, it aimed to analyze the association between the bone mineral status of patients with parathyroid diseases and the radiographic findings.
Material And Methods: A cross-sectional case-control study was conducted with individuals diagnosed with PHPT (n = 25) and post-surgical hypoPT (n = 25).

Superficial palmar branch of radial artery flap for digital skin reconstruction: anatomical study and clinical applications.
Surg Radiol Anat
December 2024
Faculty of Medicine, Dokuz Eylul University, Izmir, Turkey.
Article Synopsis
- The study examines the superficial palmar branch of the radial artery (SUPBRA) to improve techniques for reconstructing palmar skin, focusing on its anatomy and harvesting methods.
- Researchers dissected 19 male hand specimens to gather detailed anatomical data, including dimensions and positions of key structures related to SUPBRA, analyzing how best to utilize this flap in reconstruction efforts.
- Results indicated that the SUPBRA has adequate dimensions for viability in surgical applications, with specific measurements and the identification of critical vascular contributions that ensure successful use in cases of hand injury.
