“…Currently, PVA is considered a promising permanent terminal embolization agent with good biocompatibility and is commercially available for use in interventional clinical practice. [ 33 ] Of these, Libro ® Non-Adhesive Embolization [ Figure 5 ] is an ethylene vinyl alcohol copolymer containing suspended micronized tantalum powder for radiopacity, manufactured by Invamed (Ankara/Turkey). The Libro ® embolization procedure consists of MMA catheterization with access to the femoral or radial artery, followed by injection of 150–250 μm PVA.…”

Chronic subdural hematoma (c-SDH) is a frequent and serious neurological disease. It develops due to hemorrhage to the subdural space, mainly caused by head trauma. The middle meningeal artery (MMA) plays a critical role in the supply of blood to c-SDH. The decision on the type of treatment for c-SDH depends mainly on clinical and imaging evaluation. In cases in which patients are critically ill, the hematoma must be evacuated immediately. For this purpose, surgery is generally accepted as the mainstay of treatment. Among surgical techniques, twist-drill craniotomy, burr-hole craniotomy, and craniotomy are the three most used. The recurrence rate of c-SDH after surgery is an important problem with a rate of up to 30%. The technical success classification embolization of MMA (EMMA) has emerged as an effective and safe option for the treatment of c-SDH, especially those that recur. EMMA is commonly used as an adjunct to surgery or less frequently alone. The technical success of EMMA has been a promising minimal invasive strategy as an alternative or adjunctive therapy to surgical methods. Polyvinyl alcohol is the most widely used among various embolizing agents, including n-butyl cyanoacrylate, coil, and gelatin sponge. EMMA has been shown to prevent the formation or recurrence of c-SDH by eliminating blood flow to the subdural space. Complication rates are low. The large-scale comparative prospective will ensure efficacy and safety. This article aims to highlight the current information about EMMA in patients with c-SDH.

“…Each agent has its advantages and disadvantages, with factors such as size, solidity, and the need for imaging contrast agents playing a role in their effectiveness 16-18,38-40 . Gelatin sponge particles have various sizes depending on the prepared cuts, and some of its disadvantages are weak solidity leading to unstained terminal effects 41 . Polyvinyl embolic materials were used in GAE based on the experience of the interventional radiologist 17 .…”

“…Polyvinyl embolic materials were used in GAE based on the experience of the interventional radiologist 17 . Polyvinyl alcohol is a permanent embolic agent, which has several disadvantages such as vascular recanalization, lack of adhesion, and the need for an imaging contrast agent to avoid accidental embolization 41 . Bhatia et al compared IMP/CS and Embosphere microspheres for 2 years and concluded that there is no major difference in outcomes; both reduce pain and have no major AEs 22 .…”

» Genicular artery embolization (GAE) is a promising treatment option for patients with knee osteoarthritis who are unresponsive to nonsurgical treatments and not yet candidates for surgery.» Current evidence supports the effectiveness of GAE in reducing pain and synovitis, with few reported major adverse events.» The cost-effectiveness and long-term results of GAE compared with other treatment options require further investigation.» Limitations of existing studies include small sample sizes, single-center trials, and lack of comparison between embolic agents and other treatments.» Future research should focus on larger, multicenter trials with longer follow-up periods and head-to-head comparisons with alternative treatment modalities to establish the role of GAE in the management of knee osteoarthritis.
