Background: Vascular embolism is a severe complication following hyaluronic acid (HA) filler injections, with hyaluronidase injection being the most effective treatment. The nasal region, including the nose and nasolabial fold, is the most common site of vascular embolism after facial HA injections. Currently, there is insufficient clinical evidence regarding the benefits of facial artery thrombolysis.
Objectives: This article aimed to evaluate the efficacy of hyaluronidase injection via the facial artery as an emergency treatment for vascular embolism induced by facial aesthetic HA fillers.
Methods: We reviewed 14 patients who experienced nasal vascular embolism following facial HA filler injections. All 14 patients underwent percutaneous facial artery thrombolysis with a combination of hyaluronidase and urokinase administered intravascularly. For patients with longer occlusion duration and severe necrosis, femoral artery interventional thrombolysis was performed, with local injection of platelet-rich plasma to promote recovery. Follow-up ranged from 1 month to 1 year.
Results: Following facial artery hyaluronidase injection, all cases showed improvement in nasal skin lesions. Twelve patients fully recovered, while 2 patients were left with minor superficial scars and defects in the nasal wings.
Conclusions: Early thrombolysis postnasal embolism is crucial, and percutaneous facial artery puncture is an effective emergency treatment. Arterial intervention targeting the facial artery in the nasolabial fold may offer more precise thrombolysis. The combined use of hyaluronidase and urokinase is both safe and effective.

Arterial hypertension in young adults, which includes patients between 19 and 40 years of age, has been increasing in recent years and is associated with a significantly higher risk of target organ damage and short-term mortality. It has been reported that up to 10% of these cases are due to a potentially reversible secondary cause, mainly of endocrine (primary aldosteronism, Cushing's syndrome, and pheochromocytoma/paraganglioma), renal (renovascular hypertension due to fibromuscular dysplasia and renal parenchymal disease), or cardiac (coarctation of the aorta) origin. It is recommended to rule out a secondary cause of high blood pressure (BP) in those patients with early onset of grade 2 or 3 hypertension, acute worsening of previously controlled hypertension, resistant hypertension, hypertensive emergency, severe target organ damage disproportionate to the grade of hypertension, or in the face of clinical or biochemical characteristics suggestive of a secondary cause of hypertension.

Background: Adults with congenital heart disease (ACHD) can face a lifelong risk of premature cardiovascular events. Endothelial dysfunction and arterial stiffness may be some of the key mechanisms involved. Early identification of endothelial damage in ACHD could be crucial to mitigate the adverse events.

However, its performance in a Vietnamese population remains unknown. We aimed to evaluate the predictive value of the Rapid Arterial oCclusion Evaluation (RACE) scale for LVO detection in patients with ischemic stroke presenting within 24 hours in Vietnam.

Hemifacial spasm (HFS) is a disorder that causes involuntary movements of the ipsilateral facial muscles because of vascular compression of the facial nerve. Microvascular decompression (MVD), a surgical procedure to detach the culprit vessel from the nerve is believed to be the most effective treatment for HFS. Nevertheless, in the rare case in which the vessel penetrates the nerve, positioning the vessel sufficiently far from the nerve is challenging.

Glabellar filler injections are a popular non-surgical approach to address depressions and wrinkles caused by aging, muscle activity, and soft tissue loss. An anatomy-based technique emphasizes understanding the complex structure of the glabellar region, including the corrugator supercilii and procerus muscles, and the superficial vascular pathways, such as the supratrochlear and supraorbital arteries. Effective treatment involves precise filler placement, often combined with botulinum toxin to address both volume loss and dynamic wrinkles.
