Background Preoperative embolization of tumors is a well-established procedure that has been successfully applied in various clinical situations. Preoperative embolization can reduce the vascularity of tumors resulting in a clearer operative field, less difficult dissection, decreased blood loss, and, in some cases, a decrease in tumor size. However, few studies have been conducted regarding the preoperative embolization of giant thoracic tumors. Purpose To examine the effectiveness and safety of interventional embolization of giant thoracic tumors before surgical resection. Material and Methods A total of 14 consecutive patients with giant thoracic tumors received angiography and the feeding arteries of the tumors were embolized using polyvinyl alcohol (PVA) particles and gelatin sponges 1 day before surgical resection. The patient records were retrospectively reviewed and data regarding diagnoses, embolization, and surgical resection were recorded. Results Angiography revealed the feeding arteries of the tumors to be characterized by multiple branches and thickened vessel trunks with abnormal distal branches superimposed of the tumor shadow. Embolization was successfully without complications in all patients, and all feeding vessels of each tumor were occluded. Embolization reduced the severity of bleeding during surgery and decreased the difficulty of resection of the tumor. No intraoperative or postoperative complications occurred. Conclusion Interventional embolization is a safe and efficient method to facilitate the surgical resection of giant thoracic tumors.

Objectives: Priapism is a persistent erection of the penis not associated with sexual stimulation. High-flow priapism is caused by unregulated arterial inflow, usually preceded by perineal or penile blunt trauma and formation of an arterial-lacunar fistula. We present a case of high-flow priapism in a 13-year-old patient managed with polyvinyl alcohol particles. Methods: After obtaining informed consent of the parents of the minor, diagnosis was made with penile Color Doppler Ultrasound and confirmed with flush angiography. Selective arterial embolization was performed with the use of polyvinyl alcohol particles. Results: Complete detumescence was achieved without compromising the patient’s erectile function. Conclusions: The use of permanent occlusive agents like polyvinyl alcohol particles for embolization shows good occlusion rates compared to temporary agents. More studies are needed to find the safer and better agent for the treatment of high flow priapism without compromising erectile function.
