Endovascular embolization is a minimally invasive procedure used to treat various medical conditions by blocking blood flow to a specific area of the body. Here's how it relates to symptoms, treatment plans, and diagnosis testing.
Abnormal bleeding: Persistent or severe bleeding from a specific blood vessel or organ.
Pain: Chronic or acute pain localized to a specific area, often associated with a vascular abnormality.
Tumor or Aneurysm: Detection of a vascular tumor (e.g., arteriovenous malformation) or aneurysm (ballooning of a blood vessel) that requires treatment to prevent rupture or further complications.
Purpose: Endovascular embolization is performed to block or reduce blood flow to abnormal blood vessels, tumors, aneurysms, or arteriovenous malformations.
Procedure: During the procedure, a catheter is inserted into a blood vessel, typically in the groin, and guided to the site of the abnormality using imaging guidance (fluoroscopy or angiography). Once the catheter reaches the target location, embolic material (e.g., coils, particles, glue) is injected through the catheter to block blood flow and occlude the vessel or abnormality.
Risks: While endovascular embolization is generally considered safe, potential risks and complications include:
Bleeding or hematoma at the catheter insertion site
Allergic reaction to contrast dye used during the procedure
Damage to nearby blood vessels or organs
Embolization material migrating to unintended locations
Stroke or neurological complications if performed near critical blood vessels in the brain
Infection at the catheter insertion site
Imaging tests: CT scans, MRI, angiography, or Doppler ultrasound may be performed to visualize the blood vessels and identify abnormalities.
Diagnostic angiography: In some cases, a diagnostic angiogram may be performed to directly visualize blood flow within the affected area and identify the source of bleeding or abnormality.
