Comparative analysis of arterial involvement in predominant cranial and isolated extracranial phenotypes of giant cell arteritis using F-FDG PET-CT.

Department of Rheumatology, Hospital Universitario de Bellvitge. Bellvitge Biomedical Research Institute (IDIBELL), Barcelona, Spain.
Objective: To investigate differences in arterial involvement patterns on F-FDG PET-CT between predominant cranial and isolated extracranial phenotypes of giant cell arteritis (GCA).
Methods: A retrospective review of F-FDG PET-CT findings was conducted on 140 patients with confirmed GCA. The patients were divided into two groups: the cranial group, which presented craniofacial ischemic symptoms either at diagnosis or during follow-up, and the isolated extracranial group which never exhibited such manifestations.
Neurovascular Complications Following Clavicle Fracture Fixation: Timing, Mechanisms, and Clinical Implications.

This review addresses the neurovascular complications associated with the surgical treatment of clavicle fractures through open reduction and internal fixation (ORIF). Despite being a generally safe procedure, it can lead to severe complications including brachial plexopathy, pseudoaneurysm, arteriovenous fistulas (AVF), deep vein thrombosis (DVTs), and thoracic outlet syndrome (TOS). One significant observation, not often highlighted in previous literature, is that neurovascular complications are more common in cases involving delayed fixation, nonunion, or malunion, compared to those treated acutely.

Aortic dissection is the most common thoracic aortic emergency and is associated with significant morbidity and mortality. Initial complications are dependent on reduction of sheer stress against the aortic wall to protect against rupture and minimize progression of the aortic wall injury. In patients with dissection starting at or distal to the left subclavian artery (Stanford type B), initial management includes strict blood pressure and heart rate control with monitoring for any complications such as malperfusion, rupture or hemodynamic instability.

Internal Medicine, St Johns Hospital, Livingston, GBR.
Iatrogenic type A aortic dissection (IAAD) is a rare but life-threatening complication of percutaneous coronary intervention (PCI), often presenting significant therapeutic challenges. A looped guidewire between the right subclavian artery and brachiocephalic artery during coronary angiography (CAG) via right radial artery access can complicate catheter manipulation. This report discusses the case of a 58-year-old hypertensive female patient who developed aortic dissection during PCI, specifically due to wire manipulation at the brachiocephalic loop.

December 2024
Department of Rheumatology, Hospital Universitario La Paz, Madrid, Spain.
Objectives: To determine if the subtype of vascular ultrasound (US) presentation is associated with different types of ischaemic complications (IC) in giant cell arteritis (GCA).
Methods: Retrospective observational analysis of GCA clinically confirmed patients referred to US fast-track clinics at two centres. All patients underwent baseline US of cranial and extracranial arteries (carotid, subclavian and axillary).
