Introduction: Treatment of wide-necked bifurcation aneurysms often poses procedural and long-term outcome challenges. The initial preclinical experience with the Pulsar Vascular Aneurysm Neck Reconstruction Device (PVANRD) in a canine bifurcation model is described.
Methods: Experimental bifurcation vein pouch aneurysms were surgically created in the carotid arteries of eight dogs. Endovascular coiling of the aneurysms with assistance of the PVANRD was performed in all cases with acute performance compared with Y-stenting.
Results: Twelve devices were deployed in the eight cases. Deployment of the devices was straightforward and successfully protected the parent artery and maintained patency of the bifurcation in all cases, despite the use of oversized coils.
Conclusion: The PVANRD is a novel bifurcation stent that facilitates treatment of wide-necked bifurcation aneurysms compared with currently available adjunctive devices.

Background: Early literature on the Woven EndoBridge (WEB) device reported 80-90% adequate aneurysm occlusion but low complete occlusion (40-55%). It is uncertain whether residual or recurrent aneurysms require re-treatment to prevent future rupture.
Objective: To systematically review the literature to meta-analyze occlusion and complication rates after re-treatment of these aneurysms.

Venous aneurysms are fairly rare entities as compared to arterial aneurysms. Very few cases of spontaneous external jugular venous aneurysms are documented in literature without any previous history of trauma. Bilateral involvement is a further scarce finding.

Objective: To analyse the clinical, radiographic, and pathological characteristics of aneurysmal bone cyst of the jaws (JABCs), and to provide reference for clinical diagnosis and treatment.
Materials And Methods: A retrospective study was conducted on 19 patients with JABC diagnosed from 2018 to 2022.
Results: Of the 19 JABC patients (5 males, 14 females, aged 7-53 years, mean 23.

Aneurysms of the middle cerebral artery (MCA) account for up to 40% of all unruptured intracranial aneurysms [1-3] and 14% to 20% of ruptured ones. [4-5] Giant MCA aneurysms are rare, representing 10% of cases [6], but carry an aggressive natural history, with the UCAS Japan study reporting an annual rupture rate of ∼ 17%. [7].

Rupture of the thyrocervical trunk aneurysm into the thoracic cavity does not occur very often. It is an urgent condition due to hemorrhagic shock by massive hemothorax with potentially fatal consequences. Pregnancy and puerperium are additional risk factors for a rupture of the thyrocervical trunk aneurysm in patients with neurofibromatosis and aneurysms.
