Anterolateral Approach for a Cervical Nerve Root Compression Syndrome Due to an Ectatic Vertebral Artery.

BACKGROUND AND IMPORTANCE: Nerve root compression by an ectatic vertebral artery is a known but easily overlooked cause of cervical radiculopathy. Management options include nonoperative conservative therapies or surgical approaches designed to relieve the compression via anterior or posterior cervical approaches. CLINICAL PRESENTATION: A 72-yr-old female presented with a 6-mo history of sharp, shooting pain in her right arm and shoulder and deltoid weakness. Imaging demonstrated a vertebral artery loop compressing the proximal right C5 nerve root. She previously underwent both nonoperative measures as well as posterior foraminotomy at this level with limited improvement in her pain. Therefore, we performed an anterolateral approach for vascular decompression of the C5 nerve root from the vertebral artery loop. Patient has been pain-free at 1 yr with full recovery of her deltoid weakness. CONCLUSION: Vertebral artery loop formation is an uncommon cause of cervical radiculopathy, which can be readily treated by vascular decompression of the nerve root-vertebral artery loop complex. Although anomalous vertebral artery compression of a cervical nerve root is rare, it is increasingly being recognized as a readily treatable entity that can lead to lasting and full neurological recovery. We also include an operative video to illustrate the vascular decompression of an ectatic vertebral artery causing severe cervical radiculopathy.

Endoscopic burr hole evacuation of an acute subdural hematoma.

Acute subdural hematoma evacuations frequently necessitate large craniotomies with extended operative times and high relative blood loss, which can lead to additional morbidity for the patient. While endoscopic minimally invasive approaches to chronic subdural collections have been successfully demonstrated, this technique has not previously been applied to acute subdural hematomas. The authors report their experience with an 87-year-old patient presenting with a large acute right-sided subdural hematoma successfully evacuated via an endoscopic minimally invasive technique. The operative approach is outlined, and the literature on endoscopic subdural collection evacuation reviewed.
