Iliohypogastric Nerve Block
What is iliohypogastric nerve block?
Iliohypogastric nerve is a sensory nerve, which supplies the skin in the pubic region. The nerve can be damaged by surgery or scar tissue following hernia repair leading to chronic pain in the pelvic region or groin region. An iliohypogastric nerve block involves the injection of local anaesthetic close to the iliohypogastric nerve.
How is iliohypogastric nerve block done?
At Atlas Pain Care, Coimbatore, iliohypogastric nerve block is a day surgery procedure and it is done in a clean room under ultrasound guidance. Once the nerve is identified local anesthetic is injected around the nerve. The injection takes around 5 to 10 minutes.
Post procedure
The local anaesthetic usually wears off shortly after the procedure. On occasions, it might last longer. You may experience some leg weakness. Should this occur, ensure that mobilisation is kept to a minimum until the weakness subsides.
Pulsed-radiofrequency lesioning of iliohypogastric nerve
When the response to the block is good, but only lasts for a brief period, pulsed-radiofrequency lesioning of the iliohypogastric nerve is offered. At Atlas Pain Care, the radiofrequency electric needle is introduced under ultrasound-guidance and is placed close to the nerve. The proximity to the nerve is then confirmed by passing tiny electric currents. Pulsed-radiofrequency is then performed. It is a daycare procedure that takes 30-45 minutes to perform. You will be discharged home on the same day.
What are the risks associated with this procedure?
This procedure is safe. However, with any procedure, there are risks, side effects and possibility of complications. The most common side effect is temporary pain at the injection site. Fortunately, serious side effects and complications are uncommon. Ultrasound to provide visualisation of the targeted structures significantly minimises risk.
