Developmental venous anomalies (DVAs) are common congenital venous drainage anomalies. Although they typically have a benign clinical course and a low symptomatic rate, thrombosis of a drainage vein may occur, leading to potentially debilitating complications. We report imaging findings of posterior fossa DVA with a thrombosed drainage vein in a patient with nonhemorrhagic cerebellar infarct. We also review the relevant literature on the subject.

Objectives: In recent years, with the advancement of sublobar resection, A safe, painless method for locating peripheral pulmonary nodules is required. Previously, an alternative method of arterial watershed localization was been introduced to remedy the shortcomings of preoperative CT-guided localization or other methods for locating pulmonary nodules, but its technical limitations were discovered during clinical application. Therefore, we innovated a technique to localize non-subpleural nodules using basin analysis of the target vein and validated its feasibility and safety.

Objective: This study initiated a preliminary computational fluid dynamics (CFD)-based study to investigate the relationship between quantitative hemodynamics of arteriovenous malformation (AVM) draining veins and rupture.
Methods: The quantitative hemodynamics of AVM draining veins were generated from computed tomography angiography (CTA)-based steady-state CFD models. Morphological and hemodynamic parameters were compared between the ruptured and unruptured groups.

Bacterial liver abscesses commonly occur in patients with immune deficiencies such as diabetes, post-chemotherapy, or post-immunosuppressive therapy. The recommended treatment for liver abscesses exceeding 5 cm in a diameter is anti-infection therapy combined with percutaneous catheter drainage. Complications may include local spread to adjacent tissues or organs and thrombosis of the liver and portal veins.

Background: Laparoscopic radical antegrade modular pancreatosplenectomy combined with celiac axis resection and portal vein reconstruction is a new procedure for the treatment of pancreatic cancer. This surgical technique may offer patients with pancreatic cancer involving the portal vein and celiac axis an opportunity for radical surgical resection. We aim to evaluate the short- and long-term efficacy and describe the surgical details of this technique.
