Two main techniques for endovascular treatment of patients with acute ischemic stroke are direct aspiration and stent retriever thrombectomy. We hypothesized that the direct aspiration approach would be less costly than the stent retriever approach. ⋯ Costs of endovascular treatment using a direct aspiration-first pass approach are less than with a stent retriever first pass approach.

An anomalous origin of the right vertebral artery (VA) from the right internal carotid artery (ICA) occurs only rarely. ⋯ Embryologically, failure of involution of 1 of the first 6 intersegmental arteries causes various abnormal origins of the VA. The embryonic development of this anomaly is also reviewed.

Surgical Results of Intraoperative C-arm Fluoroscopy versus O-arm in Transarticular Screw Fixation for Atlantoaxial Instability.
This study compared the surgical results of transarticular screw (TAS) fixation for atlantoaxial instability between C-arm fluoroscopy and O-arm. ⋯ O-arm use improved TAS fixation accuracy. Blood loss was equivalent between the groups. O-arm-assisted TAS fixation did not prolong operative time despite the time required for setting and scanning. The O-arm is safe and useful for TAS fixation in atlantoaxial instability.

To evaluate the safety and efficacy of posterior-only surgical correction with heavy halo-femoral traction for the treatment of severe and rigid congenital scoliosis (SRCS) associated with tethered spinal cord (TSC) and type II split cord malformation (SCM). ⋯ Without prophylactic neurosurgical intervention and spine-shortening osteotomy, posterior-only surgical correction with heavy halo-femoral traction could be safe and effective for the treatment of SRCS associated with TSC and type II SCM.
