Fascia Iliaca Block for Anesthesia in Lower Limb Thromboembolectomy

The fascia iliaca block (FIB) is an anterior approach to block the lumbar plexus. It disturbed mainly to the anterior region of the thigh by blocking the femoral nerve (LFC) and the lateral femoral cutaneous nerve. Moreover, FIB may possibly be extended to the obturator, ilioinguinal, genitofemoral, lateral cutaneous nerve of the thigh and over the psoas muscle but, rarely reaches the lumbar plexus. The fascia iliaca compartment could be detected by bony landmarks palpation and the loss of resistance technique. Feeling two tactile ''pops'' due to loss of resistance occurred during the needle passage through the fascia lata and the fascia iliaca. Ultrasound (US) guidance of FIB will increase the success rate and the efficacy of sensory blockade by decreasing the needed local anesthetic amount.
