BACKGROUND AND PURPOSE MR imaging is the method of choice for evaluating the trigeminal nerve. Detection of abnormalities such as perineural tumor spread requires detailed knowledge of the normal MR appearance of the trigeminal nerve and surrounding structures. The purpose of this study was to clarify the normal MR appearance and variations of the trigeminal ganglion, maxillary nerve (V2), and ...

nerve is found in the medial aspect of the muscle; very occasionally the nerve is in very close apposition to the brachial plexus and then it may lie on the lateral aspect of the muscle and may cross it only at the point of insertion of the muscle. The accessory fibres to the phrenic nerve follow the first part of the brachial plexus taking their origin usually from the fifth or sixth cervical ...

PURPOSE The operative field for vascular access (VA) surgery in the forearm is on the volar surface, and motor nerve block is not necessary for regional anesthesia. Therefore, selective block of branches of the brachial plexus may be a more efficient anesthesia technique. METHODS Individual nerve blocks in the axillary brachial plexus and selective blocks of the musculocutaneous and medial an...

Primary tumors of the brachial plexus region are rare and granular cell tumors arising from the brachial plexus region is an extremely rare disease. We present a case of granular cell tumor arising from of the brachial plexus which appeared to be a usual presentation of nerve sheath tumor before the pathological confirmation. We report a granular cell tumor of the brachial plexus with literatur...

OBJECTIVE The study aims to demonstrate the techniques employed in surgery of the brachial plexus that are associated to evidence-based improvement of the functional outcome of these patients. METHOD A retrospective study of one hundred cases of traumatic brachial plexus injuries. Comparison between the postoperative outcomes associated to some different surgical techniques was demonstrated. ...

The sacral plexus forms the sciatic nerve, which leaves the pelvis through the greater sciatic foramen. The anatomic boundaries of the greater sciatic foramen and the relation of the sacral plexus and sciatic nerve to the structures within are identified and described on axial computed tomography (CT). The piriform muscle, which passes through the center of the greater sciatic foramen, is a rec...

Bilateral brachial plexus blocks and regional anesthesia in trauma patients are rarely performed due to potential complications when using these techniques. We illustrate a case in which bilateral infraclavicular nerve blocks were placed as part of a multimodal approach to pain management in a trauma patient. We discuss potential hazards, important considerations, and rationale for attempting t...

Most brachial plexus injuries involve the entire plexus. An injury to major cords or branches often contains a mixed injury pattern, with portions of the nerve being avulsed, ruptured, or stretched. An advancing Tinel's sign implies the possibility of neurologic recovery; however, the surgeon should combine this physical finding with that of electrodiagnostic studies to assess the extent of ner...

The potential advantages of 0.25% concentration of levobupivacaine in performing lumbar plexus with sciatic and iliohypogastric nerve block in patients with aortic stenosis is emphasized in this case report. A 48-yr old male patient who was scheduled for hip fracture surgery had severe aortic stenosis with aortic valve gradient of 85 mmHg. Anesthesia plan was combined lumbar plexus, sciatic and...
