ABSTRACT
Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder. Pseudoaneurysms formation and rupture is an unusual complication of neurofibromatosis. To date, pseudoaneurysm of the internal pudendal artery associated with NF-1 has not been reported. In this article, we present a 62-yr-old man with NF-1 suffering from spontaneous hematoma of the perinea and scrotum. A digital substraction angiography disclosed a ruptured pseudoaneurysm of the right internal pudendal artery, which was successfully managed with transcatheter embolization.

OBJECTIVE: To investigate the clinical efficacy of individual endovascular management for the treatment of different traumatic pseudoaneurysms presenting as intractable epistaxis. MATERIALS AND METHODS: For 14 consecutive patients with traumatic pseudoaneurysm presenting as refractory epistaxes, 15 endovascular procedures were performed. Digital subtraction angiography revealed that the pseudoaneurysms originated from the internal maxillary artery in eight patients; and all were treated with occlusion of the feeding artery. In six cases, they originated from the internal carotid artery (ICA); out of which, two were managed with detachable balloons, two with covered stents, one by means of cavity embolization, and the remaining one with parent artery occlusion. All of these cases were followed up clinically from six to 18 months, with a mean follow up time of ten months; moreover, three cases were also followed with angiography. RESULTS: Complete cessation of bleeding was achieved in all the 15 instances (100%) immediately after the endovascular therapies. Of the six patients who suffered from ICA pseudoaneurysms, one presented with a permanent stroke and one had an episode of rebleeding requiring intervention. CONCLUSION: In patients presenting with a history of craniocerebral trauma, traumatic pseudoaneurysm must be considered as a differential diagnosis. Individual endovascular treatment is a relatively safe, plausible, and reliable means of managing traumatic pseudoaneurysms.

Primitive trigeminal artery (PTA) and primitive otic artery (POA) is a very rare entity in adult life. We present a case of PTA and POA associated with a giant unruptured cavernous aneurysm in a 54-year-old woman. The PTA and the POA arose from the sac of the aneurysm directly, which greatly complicated endovascular therapy management.
