We describe a percutaneous approach for cerebral surgical access. After lumbar puncture, the spinal subarachnoid space was traversed by using standard angiographic guidewire techniques until the introducer catheters were in the intracranial space. Under fluoroscopic guidance, the intracranial subarachnoid space was navigated, and the ventricular system entered. Subarachnoid placement was confir...

Subarachnoid block is routinely accessed blindly by the use of anatomical landmarks in localization subarachnoid. Performing procedure using landmark technique patients with spinal deformities or morbidly obese can inflict discomfort to patient from multiple needle pricks prolonged positioning during procedure. This article aims demonstrate C-arm fluoroscopy for easy and smooth access into suba...

BACKGROUND AND PURPOSE Although it has been suggested that humoral immunity plays a role in the pathogenesis of cerebral vasospasm after subarachnoid hemorrhage, there has been no quantitative assay for cellular immunity. We studied the kinetics of immune cells in the subarachnoid space after subarachnoid hemorrhage in the rat. METHODS One hundred fourteen Sprague-Dawley rats were used in thi...

OBJECTIVES To determine the feasibility of evaluating the subarachnoid space by measuring two novel sonographic parameters in axial section using transabdominal ultrasound, in addition to the parameters previously defined in coronal section, and to construct a normal range for the subarachnoid space width in singleton healthy fetuses. METHODS Healthy pregnant women between 20 and 29 weeks wer...

Subarachnoid Space Opacification on Delayed Postcontrast Fluid-Attenuated Inversion Recovery Imaging in Spontaneous Intracranial Hypotension: Visualizing the Monro-Kellie Hypothesis Intracranial volume compensatory changes explained by the MonroKellie hypothesis (MKH) occur in spontaneous intracranial hypotension (SIH) and may be seen on MR imaging. This case illustrates previously unreported f...

Development of a communication between the spinal subarachnoid space and the pleural space after thoracic spine surgery is uncommon. Subarachnoid pleural fistula (SAPF), a distressing condition, involves cerebrospinal fluid leakage. Here we report an unusual case of SAPF, occurring after thoracic spine surgery, that was further complicated by pneumocephalus and pneumorrhachis postthoracentesis,...

BACKGROUND Measurements of the subarachnoid space during routine cranial sonography may provide an indirect method of monitoring brain growth in preterm infants. METHODS The width of the subarachnoid space was measured on coronal views during head sonography. Initial scans (within five days of birth) were compared with follow up scans. RESULTS A total of 361 scans were performed on 201 pret...
