This study has demonstrated that aneurysms occur in about 50 percent of the rat femoral arteries subjected to microvascular anastomosis. These aneurysms are consistent histologically--being characterized by medial necrosis, loss of elastic lamellae, and subintimal hyperplasia. Mechanical trauma is implicated as a factor in their pathogenesis, though further study in necessary to define the exact etiology.

Purpose: This study aims to present our experience with superselective embolization of the anterior spinal artery-bearing segmental artery (ASAbSA) using a microvascular plug (MVP) during the minimally invasive segmental artery coil embolization (MISACE) procedure prior endovascular repair of the thoracoabdominal aortic aneurysms.
Methods: We retrospectively evaluated all MISACE procedures performed between May 2018 and July 2023, where MVP was deployed into an angiographically confirmed ASAbSA. Data were analyzed regarding interventional details, technical aspects, and safety protocols.

Purpose: To determine the efficacy and safety of proton beam irradiation (PBI) and anti-vascular endothelial growth factor (anti-VEGF) therapy for polypoidal choroidal vasculopathy (PCV)/ aneurysmal type 1 macular neovascularization (AT1).
Methods: The randomized clinical trial consisted of newly diagnosed active PCV/AT1 patients who were randomized 1:1 to treatment with three initial monthly intravitreal anti-VEGF agent (conbercept) injections with or without single 14 GyE radiation. Subsequent anti-VEGF therapy was given pro re nata.

Rationale: Rete mirabile (RM) is rare in humans, normally existing in lower mammalian arteries. To study its clinical and imaging features, we report an extremely rare case that occurred in humans and review the literature.
Patient Concerns: A 43-year-old female patient was admitted to our hospital because of recurrent dizziness and headache for 4 years.
