Hemorrhoid Embolisation
Hemorrhoid embolisation is a minimally invasive, conservative, and painless radiological intervention designed to treat chronically bleeding internal hemorrhoids when other medical treatments fail to control the bleeding. The procedure is performed by an interventional radiologist under local anesthesia in an outpatient setting.
Embolisation Process
-
Patient Preparation: The patient is under local anesthesia and experiences no pain.
-
Catheter Insertion: The radiologist inserts a catheter through the radial or femoral artery and navigates it to the blood vessels of the rectum and anal canal.
-
Artery Blockage: Under radiological control, the rectal arteries are blocked using coils or micro-coils. Embolization leaves no scars and does not damage the surrounding healthy tissue.
-
Symptoms of Internal Hemorrhoids
-
Bleeding: Internal hemorrhoids often cause acute or chronic bleeding, which can be disabling on a daily basis.
-
Prolapse: In chronic cases, hemorrhoids can cause prolapse, heaviness, leakage, and anal itching.
Principle of Embolisation
Blocking the superior rectal arteries, which are responsible for supplying blood to the hemorrhoidal plexus, aims to relieve the congestion. Reduced flow will be maintained by the middle and inferior rectal arteries.
Indications for Hemorrhoid Embolisation
-
Chronically Bleeding Hemorrhoids: When hemorrhoids cause disabling daily bleeding or require transfusions, especially in patients taking anticoagulants that cannot be discontinued.
-
Failure of Other Treatments: Embolisation serves as an alternative when medical, endoscopic, or surgical treatments have failed.
Other Treatments for Internal Hemorrhoids
-
Instrumental Endoscopic Treatment
-
Surgical Excision
-
Surgical Ligation under Doppler Guidance
These treatments can be effective but may involve pain and the need for painkillers for several days, depending on the technique used. Possible complications include chronic anal pain, fecal urgency, and fistulas.
Contraindications for Embolisation
Prolapse or Pain: Embolisation does not improve symptoms of prolapse or pain and is therefore not a good option in these cases.
