Objectives/hypothesis: Massive epistaxis due to ruptured pseudoaneurysm of the internal carotid artery (ICA) is an often fatal complication of radiation treatment for patients with nasopharyngeal carcinoma. We review the clinical characteristics and predictors of survival in patients suffering from this serious complication after radiotherapy.
Study Design: Retrospective case series.
Methods: Clinical records and radiological investigations of postirradiated NPC patients with ICA pseudoaneurysm diagnosed with digital subtraction angiography in Queen Mary Hospital from January 2003 to December 2012 were reviewed. Risk factors analyzed for survival included gender, size of initial tumor, history of second course of radiotherapy, history of previous maxillary swing nasopharyngectomy, presence of persistent disease, successful initial hemostasis, successful airway control, and endovascular treatment.
Results: Twenty-six were included in the analysis. Twenty-three patients underwent endovascular treatment, and 20 (87%) had successful control of the bleeding. Eighteen (69%) patients survived. Univariate analysis showed that successful temporary control of bleeding and airway control were associated with survival.
Conclusions: Prompt bleeding control and airway management is necessary to improve survival. Endovascular treatment is a good definitive treatment option with a high success rate.

Background: Central arterial stiffening is associated with brain white matter (WM) damage and gray matter (GM) volume loss in older adults, but little is known about this association from an adult lifespan perspective.
Purpose: To investigate the associations of central arterial stiffness with WM microstructural organization, WM lesion load, cortical thickness, and GM volume in healthy adults across the lifespan.

Cardiovascular disease remains a prominent cause of disability and premature death worldwide. Within this spectrum, carotid artery atherosclerosis is a complex and multifaceted condition, and a prominent precursor of acute ischaemic stroke and other cardiovascular events. The intricate interplay among inflammation, oxidative stress, endothelial dysfunction, lipid metabolism, and immune responses participates in the development of lesions, leading to luminal stenosis and potential plaque instability.

Background: Heart failure with preserved ejection fraction (HFpEF) is a high prevalence condition, with high rates of hospitalization and mortality. Arterial hypertension is the main risk factor for HFpEF. Among hypertensive patients, alterations in cardiac and vascular morphology identify hypertension-mediated organ damage (HMOD).

We report a rare case of a missed intracavernous internal carotid artery dissecting aneurysm occurring as a complication of the base of skull fracture with severe brain injury causing acute cavernous sinus syndrome with permanent vision loss. A 31-year-old Myanmar lady had an alleged motor vehicle accident and suffered severe traumatic brain injury with multiple intracranial bleeds, multiple facial bone and base of skull fractures, and limb fractures. At one week post-trauma, she had severe right eye proptosis with vision loss, ophthalmoplegia, chemosis, and high intraocular pressure.

Objective: The objective was to evaluate the relationship between carotid stenting and off-pump coronary artery grafting (CAS-OPCABG) and OPCABG only in patients with asymptomatic severe carotid stenosis.
Methods: This study retrospectively included 669 patients with asymptomatic severe carotid artery stenosis who underwent OPCABG at multiple centers. After propensity score matching for baseline characteristics, the study compared two groups of patients with clinical data, early and midterm death, stroke, and myocardial infarction (MI).
