Traumatic pseudoaneurysm of the superficial temporal artery treated by endovascular coil embolization

Palpable Pulsatile Mass of the Forehead: A Case Series of Superficial Temporal Artery Pseudoaneurysms

“…However, only three case reports with spontaneous rupture of the STA-pseuodoaneurysm have been described in literature. Surgical resection under general or local anesthesia is considered the standard therapy [1,2,4,9]. The pseudoaneurysm is localized with subsequently ligation of the proximal and distal STA; next, the pseudoaneurysm is completely resected [10].…”

“…In these cases, adequate dissection of the parotid gland and the facial nerve before ligation and resection of the aneurysm may pose a greater threat than the aneurysm itself, justifying endovascular embolization as the first choice of treatment [1]. Compared to surgical resection, coil embolization requires a longer peroperative time but has a shorter recovery time and avoids/minimizes the surgical scar [1,9]. Nikolakopoulos et al, suggest that an endovascular approach should only be performed when angiography is mandatory for diagnosis [5].…”

“…In contrast to coil-embolisation, local injection of thrombin has a higher incidence of complications such as allergic reactions, risk for recanalisation and distal ischemia [5,9]. Other disadvantages are the lag time for resolution of the thrombosed pseudoaneurysm and the need for reexamination with duplex ultrasound to ensure no recanalization of the pseudoaneurysm has occurred [5].…”

Management of Pseudoaneurysm of Internal Maxillary Artery Resulting from Trauma

“…Numerous sizes and types of stents are utilized for many different clinical applications; viz., covered and bare stents. Stents and stent grafts have the advantage that they maintain the patency of vessel lumen [14,15]. However the presence of extensive collateral between vessels of the right side and left side of the face and various anastamosis between internal and external carotid arteries, the embolisation or surgical ligation of external carotid artery does not cause any significant compromise of blood supply to the peripheral tissues.…”

Traumatic Pseudoaneurysm of the Superficial Temporal Artery due to Gardner Traction

“…Most STA pseudoaneurysms occur within 2-6 weeks after injury, although the time window ranges from just a few hours to as long as 10 years 6,7,13) . The majority of STA pseudoaneurysms involve the anterior branch because of the lack of cushioning at the site where the artery crosses from the temporalis to the frontalis muscle, and because of the tethering effect of the fascia at this level which limits any lateral displacement of the artery in response to tangential forces 4,5) . More than 95% of pseudoaneurysms are traumatic in origin.…”
