A new method of subarachnoid puncture for clinical diagnosis and treatment: lateral atlanto-occipital space puncture

OBJECTIVELumbar puncture may not be suitable for some patients needing subarachnoid puncture, while lateral C1–2 puncture and cisterna magna puncture have safety concerns. This study investigated lateral atlanto-occipital space puncture (also called lateral cisterna magna puncture) in patients who needed subarachnoid puncture for clinical diagnosis or treatment. The purpose of the study was to provide information on the complications and feasibility of this technique and its potential advantages over traditional subarachnoid puncture techniques.METHODSIn total, 1008 lateral atlanto-occipital space puncture procedures performed in 667 patients were retrospectively analyzed. The success rate and complications were also analyzed. All patients were followed up for 1 week after puncture.RESULTSOf 1008 lateral atlanto-occipital space punctures, 991 succeeded and 17 failed (1.7%). Fifteen patients (2.25%) reported pain in the ipsilateral external auditory canal or deep soft tissue, 32 patients (4.80%) had a tran...
