Background: Survival for glioblastoma remains very poor despite decades of research, with a 5-year survival of only 5%. The technological improvements that have revolutionized treatment of ischemic stroke and brain aneurysms have great potential in providing more precise and selective delivery of cancer therapeutic agents to brain tumors.
Methods: We describe for the first time the use of perfusion guidance to enhance the precision of endovascular super-selective intra-arterial (ESIA) infusions of mesenchymal stem cells loaded with Delta-24 (MSC-D24) in the treatment of glioblastoma (NCT03896568).
Results: MRI imaging, which best defines the location of the tumor, is co-registered and fused with the patient's position using cone beam CT, resulting in optimal vessel selection and confirmation of targeted delivery through volumetric perfusion imaging.
Conclusions: This technique of perfusion guided-ESIA injections (PG-ESIA) enhances our ability to perform targeted super-selective delivery of therapeutic agents for brain tumors.

Peripheral aneurysms associated with moyamoya disease, particularly those originating from the anterior choroidal artery, often have a poor prognosis and are typically managed with endovascular treatments. Comprehensive imaging diagnostics and anatomical expertise are critical in minimizing ischemic complications during treatment. We present a case of a 55-year-old woman with a rapidly enlarging distal anterior choroidal artery aneurysm identified during an intracerebral hemorrhage associated with moyamoya disease.

High-grade gliomas (HGGs) have a poor prognosis and are difficult to treat. This review examines the evolving landscape of endovascular therapies for HGGs. Recent advances in endovascular catheter technology and delivery methods allow for super-selective intra-arterial cerebral infusion (SSIACI) with increasing precision.

Introduction And Importance: Intraparenchymal renal artery aneurysms are a really rare condition that represents <10 % of all renal artery aneurysms. They are more often caused by trauma or iatrogenic injury and their rupture can lead to life-threatening hemorrhage.
Case Presentation: We report the case of a 25-year-old male with history of back stab wound three months before being admitted to our unity.

Background: True uterine artery aneurysms, especially during pregnancy, are a rare entity and not well understood. Clinical symptoms are unspecific pelvic pain and pressure. Diagnosis can be confirmed by transvaginal color-coded-sonography and/or magnetic resonance imaging.
