Surgical excision of orbital cavernous venous malformations located in the orbital apex is challenging due to difficulty obtaining surgical exposure and higher risk of morbidity. Intralesional bevacizumab injection has been utilized for the treatment of choroidal and intracranial cavernous venous malformations. A 52-year-old woman with an orbital apical mass consistent with a cavernous venous malformation causing decreased visual acuity, diminished color vision, and visual field loss was treated with intralesional bevacizumab injected under direct surgical visualization. Subsequently, she demonstrated improved visual acuity, color vision, and slow but dramatic visual field improvement over one year. Injection of bevacizumab may be a viable alternative treatment for orbital cavernous venous malformations.

Objective: This study aims to elucidate the anatomical principles governing the surrounding venous structures (VS) of the horizontal part of the third segment of the vertebral artery (V3h) and develop a safe and bloodless surgical technique for exposing V3h.
Methods: This study used ten formalin-infused cadaveric head specimens. The dissections were performed stepwise to simulate the far lateral approach process, exposing the V3h with a novel technique.

Description: Portal vein thromboses (PVTs) are common in patients with cirrhosis and are associated with advanced portal hypertension and mortality. The treatment of PVTs remains a clinical challenge due to limited evidence and competing risks of PVT-associated complications vs bleeding risk of anticoagulation. Significant heterogeneity in PVT phenotype based on anatomic, host, and disease characteristics, and an emerging spectrum of therapeutic options further complicate PVT management.

Background: Liver hemangiomas (HGs) are characterized by cavernous venous spaces delineated by a lining of vascular endothelial cells and interspersed with connective tissue septa. Typically, a liver HG has higher apparent diffusion coefficient (ADC) and T2 values than those of hepatocellular carcinomas (HCCs) and liver metastases, and lower ADC and T2 values than those of liver simple cysts. However, a portion of HGs shows ADC and T2 overlapping with those of HCC, liver metastasis, and simple cyst.

Carotid-cavernous aneurysms (CCAs) have the potential for growth, and their risk of rupture can lead to severe complications. Treatment is typically recommended to prevent these complications, with endovascular therapy being the preferred approach due to the challenging surgical access. This case presents a rare instance of rupture of a CCA that had been previously treated with a flow-diverting stent, which resulted in the development of a carotid-cavernous fistula, requiring venous access endovascular treatment.
