Objectives: To report our experience with transarterial glue embolization of the bronchial artery for life-threatening hemoptysis.
Materials And Methods: Twenty-five patients underwent bronchial artery embolization, using coaxial microcatheter technique, with a liquid agent, n-butyl-2-cyanoacrylate (NBCA), named glue, for life-threatening hemoptysis. The technical and clinical outcomes were followed in terms of immediate control of bleeding, recurrence of hemoptysis and complications of the procedure.
Results: Four patients had acute hemoptysis when they were evaluated. The average number of arteries embolized per patient was 2.9. BAEs were successful in controlling hemoptysis immediately in all 25 patients (100%) and in 24 patients (96%) at 1 month follow-ups. One patient had recurrent hemoptysis on the tenth day after embolization. The follow-up time ranged from 2 to 63 months (mean 14 months). Six patients (25%) died all as a result of their disease process. Bleeding recurred in 3 patients after 30 days (7th, 11th, 12th months). One patient had vomitting attacks with dysphagia after the procedure that lasted 24h. Three patients had transient thoracic pain lasting 3-5 days. There were no procedure related spinal or vascular complications.
Conclusions: Glue embolization with microcatheter technique is a safe and effective treatment in cases of life-threatening hemoptysis with a very high rate of success and low rate of complications.

Purpose: To evaluate the safety and efficacy of lymphatic embolization for primary genital lymphorrhea.
Materials And Methods: A retrospective analysis was conducted on patients who underwent lymphatic embolization for primary genital lymphorrhea and/or lower limb lymphedema between May 2016 and January 2022 at three specialized lymphatic centers. Following radiological evaluation of genital lymphorrhea, affected lymphatic vessels were selectively embolized to occlude abnormal lymphatic flow using a mixture of N-butyl cyanoacrylate glue and ethiodized oil.

Gastric varices (GVs) are dilated veins in the stomach submucosa, typically caused by portal hypertension. A prompt diagnosis is needed, given the significant risk of bleeding and mortality. Endoscopic cyanoacrylate injections are widely adopted for treating GV due to their efficacy in preventing rebleeding with lower complication rates.

This study aims to evaluate the safety and efficacy of α-n-butyl-2-cyanoacrylate (NBCA) glue in comparison with traditional embolization materials for the treatment of acute renal hemorrhage. A total of 105 patients with the acute renal hemorrhage who underwent superselective renal artery embolization were enrolled. The patients were divided into two groups based on the embolization materials used: the traditional group (43 cases, control group) and the medical glue group (62 cases, observation group).
