The catheter is then carefully navigated through the arterial system with x-ray guidance until it reaches the branches of the superior rectal artery that supply blood to the hemorrhoidal plexus. [3] Once in position, microparticles and/or microcoils are injected through the catheter to block these arteries, thereby reducing the blood supply to ...
It is a kind of catheter intervention to control hemoptysis (airway bleeding) by embolizing the bronchial artery, which is a bleeding source. Embolic agents are particulate embolic material such as gelatin sponge or polyvinyl alcohol (PVA), and liquid embolic material such as NBCA, or metallic coils. [1]
Under fluoroscopic guidance, a catheter is then introduced into the artery and used to select the uterine vessels for subsequent embolization. Once at the level of the uterine artery an angiogram with contrast is performed to confirm placement of the catheter, and the embolizing agent (spheres or beads) is released. As more embolizing agent is ...
A normal menstrual cycle is 21–35 days in duration, with bleeding lasting an average of 5 days and total blood flow between 25 and 80 mL. Heavy menstrual bleeding is defined as total menstrual flow >80ml per cycle, soaking a pad/tampon at least every 2 hours, changing a pad/tampon in the middle of the night, or bleeding lasting for >7 days.
Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.
During the procedure, a catheter is inserted into the affected artery, and the clot is removed using a variety of techniques such as mechanical fragmentation or suction. However, it's important to note that there is a risk of complications such as bleeding, infection, and damage to the artery or surrounding tissue.

The catheter site is checked for bleeding and swelling and the heart rate and blood pressure are monitored to detect late rupture and hemorrhage. [26] Post-procedure protocol also involves monitoring urinary output, cardiac symptoms, pain and other signs of systemic problems. [ 26 ]
