Purpose: Report of a case of central retinal artery occlusion following sphenopalatine artery (SPA) embolization. A review of the literature describing complications following SPA embolization and ligation.
Methods: Retrospective case report and literature review.
Results: A 68-year-old woman with a history notable for hypertension, hyperlipidemia, and eight years of intermittent right-sided epistaxis previously requiring blood transfusions underwent right-sided embolization of the SPA with the neurosurgery service. SPA embolization was achieved with Embosphere microspheres and Concerto coils. No thromboembolic complications were noted at the conclusion of the case. On waking from general anesthesia, the patient reported painless right sided vision loss and was found to have best-corrected visual acuity of light perception, a relative afferent pupillary defect, and a cherry-red spot with vascular attenuation consistent with central retinal artery occlusion (CRAO).
Conclusions: CRAO can be a complication of ipsilateral SPA embolization.

Introduction: Middle Meningeal Artery Embolization (MMAE) in patients with chronic SubDural Hematoma (cSDH) is a novel treatment approach, albeit the specific role of MMAE in the treatment of cSDH is not yet defined.
Research Question: The aim of this work is to provide a consensus-based statement from a multidisciplinary panel on the current role of MMAE in patients with cSDH.
Materials And Methods: A literature search was performed using the keywords MMAE and cSDH.

Background: Trans-arterial embolization (TAE) via the ophthalmic artery and middle meningeal arterial are the common arterial routes for anterior cranial fossa (ACF) dural arteriovenous fistulas (DAVFs). However, TAE via the sphenopalatine artery (SPA) to treat ACF DAVFs is rarely reported. Here, we describe 14 cases of ACF DAVFs that were either treated solely or in conjunction with other arterial routes via the SPA.

Sphenopalatine artery pseudoaneurysm masquerading as a second primary maxillary carcinoma.

Purpose: Maxillary sinus carcinomas usually present as a locally advanced disease at the time of diagnosis and it is extremely unusual to have a second primary maxillary carcinoma on the contralateral side after many years of completion of treatment of the first malignancy. We present here a case report of a sphenopalatine artery (SPA) pseudoaneurysm mimicking the second primary maxillary carcinoma.
Methods: We reviewed the literature for SPA pseudoaneurysm.

Article Synopsis
- A review analyzes various treatment plans for posterior epistaxis, acknowledging the limitations of existing research due to its retrospective nature and the ethical challenges of large-scale studies.
- The research utilized PubMed to gather literature on treatment methods and guidelines, focusing on key terms related to management and surgical options for posterior epistaxis.
- The findings suggest that early surgical intervention may be more effective than nasal packing, and there is a call for updated treatment guidelines based on the latest research outcomes.
