Polyvinyl alcohol (PVA) particles have been widely used as an embolic material for endovascular treatment of vascular enriched tumors, especially for meningiomas. However, there are disadvantages with their use due to the fact that they are radiolucent, with a very irregular shape and a tendency for self-adhesion. With alternative organic liquids there is also a possibility of toxicity. We have therefore developed a new embolic material, platinum balls, which feature radioopacity, a relatively well-defined oval shape, multi-pitted and indented surfaces on electron microscopy and a lower tendency for self-adhesion Based on positive findings in experimental studies, embolization of meningiomas was conducted with platinum balls in 27 patients and the results compared with findings for a matched group previously treated with PVA particles.Total volume of blood transfused during surgery was comparable in the two cases, although a tendency for lower values was noted with the platinum balls, and outcome was equally positive.

Introduction: Achieving an early diagnosis of chronic thromboembolic pulmonary hypertension (CTEPH) in pulmonary embolism (PE) survivors results in better quality of life and survival. Importantly, dedicated follow-up strategies to achieve an earlier CTEPH diagnosis involve costs that were not explicitly incorporated in the models assessing their cost-effectiveness. We performed an economic evaluation of 11 distinct PE follow-up algorithms to determine which should be preferred.

Introduction: During a cerebrovascular procedure, diligent care is made to ensure no air is present in lines and connectors. Should air enter the cerebral vasculature, cerebral air emboli can cause worsening neurological outcome or death. This communication outlines how a process change of refrigerating mixed heparin for storage lead to the presence of unintentional air, or off-gassing of the fluid.

Introduction: Dural arteriovenous fistulas (dAVF) are abnormal anastomoses between meningeal arteries and dural venous sinuses. Typically, dAVF treatment involves an endovascular or microsurgical approach. Anterior ethmoidal artery (AEA) dAVFs pose unique challenges due to their anatomy and location.

Objective: To study immediate therapeutic outcomes, subsequent fertility effects and menstrual changes in cesarean scar pregnancy patients who received uterine artery embolization with or without methotrexate followed by ultrasound guided curettage.
Materials And Methods: Totally, 82 patients who met the inclusion criteria were enrolled in our study and divided into two groups. Group I included 50 patients who received uterine artery embolization and ultrasound guided curettage, and Group II had 32 patients who received uterine artery embolization plus methotrexate and ultrasound guided curettage.

Objective: This study aimed to evaluate the safety and efficacy of vacuum-induced intrauterine balloon tamponade (vIBT) using the modified Bakri system in a clinical setting.
Materials And Methods: This single-center observational study included women who had undergone vIBT for primary postpartum hemorrhage (PPH). Vacuum induction at 60 kPa in the uterus was continued for 1 h with 50-100 ml saline, and the balloon was promptly removed after the protocol was completed.
