Management of pseudoaneurysms of the internal maxillary artery derived from orthognathic surgery based on one case.

Purpose: The purpose of this article is to highlight the risk of pseudoaneurysms formation after orthognathic surgery, their clinical features and management.

Methods: A case report of a 24-year-old man who suffered a pseudoaneurysm of the internal maxillary artery after sagittal osteotomy during orthognathic is reported. After three bleeding episodes, a pseudoaneurysm was diagnosed with a computed tomography angiogram (CTA) and treated with an embolization of the internal maxillary artery with polyvinyl alcohol (PVA) successfully.

Accuracy of SCORTEN and ABCD-10 to predict mortality and the influence of renal function in Stevens-Johnson syndrome/toxic epidermal necrolysis.

Epidermal necrolysis (EN) compromises a spectrum of life-threatening dermatoses (Stevens-Johnson Syndrome [SJS], overlap syndrome and toxic epidermal necrolysis [TEN]). Currently, no active therapeutic regimen with unequivocal benefit exists for SJS/TEN. SCORTEN is the widely-used prognostic scale specific for SJS/TEN.
