The lesser occipital nerve (or small occipital nerve [1]) is a cutaneous spinal nerve of the cervical plexus. [2] It arises from second cervical (spinal) nerve (C2) (along with the greater occipital nerve). It innervates the skin of the back of the upper neck and of the scalp posterior to the ear.
Caudal anaesthesia is a relatively low-risk technique [4] commonly used, either on its own or in combination with sedation or general anaesthesia. [3] [5]Caudal anesthesia may be favored for sub-umbilical region surgeries in the pediatric population, such as inguinal hernia repair, circumcision, hypospadias repair, anal atresia, or to immobilise newborns with hip dysplasia.
They are most prominent in the cervical region [1] where they form anastomoses with the vertebral, occipital, and deep cervical veins. [2] The anterior external vertebral venous plexuses are situated anteriorly to the vertebral bodies. They communicate with the basivertebral and intervertebral veins, and receive tributaries from the vertebral ...
The cervical plexus is a nerve plexus of the anterior rami of the first (i.e. upper-most) four cervical spinal nerves C1-C4. [1] [2] ... and deep cervical fascia. [1]
The brachial plexus is most compact at the level of the trunks formed by the C5–T1 nerve roots, so nerve block at this level has the greatest likelihood of blocking all of the branches of the brachial plexus. This results in rapid onset times and, ultimately, high success rates for surgery and analgesia of the upper extremity, excluding the ...
Ultrasonography of deep venous thrombosis; Ultrasonography of chronic venous insufficiency of the legs; Duplex evaluation is usually done prior to any invasive testing or surgical procedure. [8] Ultrasound duplex scanning can provide additional information that may guide therapeutic decisions.

Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.
