Objective: To investigate the safety and efficacy of Willis covered stents (WCSs) in the treatment of traumatic pseudoaneurysm of the cranial internal carotid artery (CICA). Methods: Fifteen patients with traumatic pseudoaneurysm of the intracranial segment of the ICA treated with the WCS system at our institution from 2013 to 2019 were analyzed retrospectively. Follow-up observation and digital subtraction angiography (DSA) examination were conducted approximately 6 months after the treatment. Results: DSA performed immediately after stent deployment revealed that complete occlusion of the lesion was achieved in 13 patients and that endoleak occurred in 2 patients. In 12 patients, postoperative DSA examination indicated that the lesions were completely occluded. In 2 patients who had a second stent implantation at the break of the ICA, traumatic ICA rupture was essentially completely obstructed in 1 patient. The endoleak remained in 1 patient with carotid cavernous sinus fistula because the placement of the second stent system was difficult with his ICA tortuosity. No recurrence of aneurysms, hemorrhage, or other lesions was observed, and the patients’ parent arteries were patent without stenosis. No procedure-related complications or deaths occurred during the follow-up period of approximately 6 months. Conclusions: For treatment of traumatic pseudoaneurysm of the CICA, Willis covered stent implantation is safe and effective. However, large-sample controlled studies and multicenter studies are needed for further confirmation.

OBJECTIVEThe endoscopic endonasal approach has become a routine corridor to the suprasellar region. The superior hypophyseal arteries (SHAs) are intimately related to lesions in the suprasellar space, such as craniopharyngiomas and meningiomas. Here the authors investigate the surgical anatomy and variations of the SHA from the endoscopic endonasal perspective.METHODSThirty anatomical specimens with vascular injection were used for endoscopic endonasal dissection. The number of SHAs and their or...

Objective We investigated immediate/late endoleaks and long-term patency following stent-graft placement for treatment of intracranial aneurysms located within the distal internal carotid artery (ICA) or vertebral artery (VA).

Object In this study the authors determined the patency rate of the ophthalmic artery (OphA) after placement of 1 or more flow diversion devices across the arterial inlet for treatment of proximal internal carotid artery (ICA) aneurysms, and correlated possible risk factors for OphA occlusion. Methods Nineteen consecutive patients were identified (mean age 53.9 years, range 23–74 years, all female) who were treated for 20 ICA aneurysms. In all patients a Pipeline Embolization Device (PED) was pl...

We report a case of traumatic internal carotid artery pseudoaneurysm near the skull base that was successfully treated with anticoagulation and antiplatelet therapy and two overlapping bare stents placed under intravascular ultrasound guidance. Although incomplete exclusion of the pseudoaneurysm was seen on completion angiography, follow-up computed tomography angiography revealed complete resolution of the treated lesion. The patient remains asymptomatic at the 18-month clinical follow-up. This...

Objective We designed a carotid siphon (CS) aneurysm model in dogs to test a new stent graft (the Willis covered stent) and compared tissue reaction over 12-month follow-up versus a comparison group with stents implanted in straight vessels.

Blunt traumatic injuries of the intracranial carotid arteries can result in pseudoaneurysm formation. A pseudoaneurysm of the intracavernous carotid artery may rupture into the cavernous sinus, causing life-threatening epistaxis. We report a case of intracavernous traumatic psedoaneurysm presenting with delayed massive epistaxis. The endovascular treatment with overlapping self-expanding stents achieved complete exclusion of the pseudoaneurysm with preservation of the intracavernous carotid arte...

BACKGROUND AND PURPOSE: We present our preliminary experience, including mid-term angiographic and clinical follow-up results, with an alternative technique for the endovascular treatment of intracranial aneurysms in a series of patients. This new method, previously described in anecdotal case reports, consists of endovascular deployment of an artificial vessel graft (stent graft or covered stent) in the parent vessel to exclude the intracranial aneurysm sac from circulation. METHODS: Twenty-fiv...
