Vascular malformation

This trial investigates whether injecting bleomycin directly into low-flow vascular malformations (abnormal clusters of blood or lymph vessels) in the head and neck can shrink them. Twenty participants will receive up to four sessions of the drug under local anesthesia. The main …

This study tested a cream containing sirolimus on rare skin growths called microcystic lymphatic malformations, which can ooze, bleed, and cause pain. 55 children and adults applied the cream to one area and a placebo cream to another for 12 weeks. The goal was to see if the siro…

This study compared the effectiveness and safety of different sclerosing agents, including ethanol, for treating low-flow vascular malformations. Seventy-five participants with trunk or extremity lesions received injections under ultrasound guidance. The goal was to see which age…

This study tested the drug sirolimus (rapamycin) in 63 children aged 6 to 18 with large, complicated slow-flow vascular malformations (abnormal blood or lymph vessels). Each child had an observation period followed by 4 to 8 months of sirolimus treatment. The main goal was to see…

This study tests a new contrast agent called HRS-9231 for MRI scans of body parts (excluding the brain and spine). The goal is to see if it makes abnormal blood vessels or lesions show up as clearly as a standard contrast agent. About 309 adults who already need a contrast MRI ar…

This early-phase study tested a freezing technique called cryoablation on 14 adults with painful venous malformations that had come back after standard treatments like surgery or sclerotherapy. The main goal was to check safety and see if it could ease pain and discomfort. Result…

This study follows about 800 people undergoing angiographic procedures with redesigned Beacon Tip catheters. The goal is to see if the catheters can be safely navigated to the intended location and used for tasks like releasing contrast dye or taking anatomical measurements. Rese…

This completed study created a French national registry for people with rare overgrowth syndromes caused by PIK3CA gene mutations. Researchers collected medical and genetic information from 28 patients to better understand these conditions and estimate how many people are affecte…

This study followed 150 children aged 2 to 12 who have a port wine stain on a leg. Researchers tracked how the stain changes as the child grows, and whether it leads to problems like blood vessel issues or bone growth differences. The goal was to learn more about the condition an…
