Abstract BACKGROUND Spinal catheter insertion in lumboperitoneal (LP) shunt surgery for idiopathic normal pressure hydrocephalus (iNPH) is frequently associated with technical difficulties especially in patients with obesity and elderly patients with vertebral deformities. OBJECTIVE To elucidate the accuracy and safety of image-guided spinal catheter placement using a paramedian approach (PMA). METHODS We retrospectively analyzed 39 consecutive iNPH patients treated by LP shunting with spinal catheter insertion via the PMA. The success rate of catheter placement and the number of changes in puncture location were evaluated. Accuracy of catheter insertion was assessed by measuring both vertical and horizontal deviations in the point of catheter dural penetration from the center of the interlaminar space. RESULTS The success rate of catheter placement was 100% (39/39). The difficulty rate for catheter insertion, measured by the number of changes in puncture location, was 2.6% (1/39). No bloody punctures or surgical infections were observed. Accuracy of catheter insertion, measured as the degree of deviation, was 0.5 ± 1.9 mm horizontally and 0.0 ± 2.4 mm vertically. The rates of minor complications, including caudal catheter insertion, transient low-pressure headache, and root pain, were 5.1% (2/39), 10.4% (4/39), and 0% (0/43), respectively. Subdural hematoma requiring surgical intervention occurred in 1 case (2.6%). During the mean follow-up period of 36 mo, spinal catheter rupture at the level of the spinous processes was not observed. CONCLUSION Fluoroscopic-guided spinal catheter placement via the PMA was safe, accurate, and reliable, even for use in geriatric and obese patients.

Abstract OBJECTIVE Spinal catheters are often inserted for treatment of cerebrospinal fluid leaks; however, they have recently been recommended for elective cerebrospinal fluid drainage to identify patients with possible normal pressure hydrocephalus who are most likely to respond to shunt surgery. The rate of spinal catheter-associated meningitis with elective spinal catheter insertion is unknown. The objective was to determine the rate of infection and risk factors associated with elective spinal catheter insertion for evaluation of hydrocephalus and idiopathic intracranial hypertension (IIH). METHODS We retrospectively analyzed clinical and microbiological data and cerebrospinal fluid results of patients admitted during 60 consecutive months who had elective spinal catheter insertion for evaluation of normal pressure hydrocephalus or IIH. RESULTS A total of 461 spinal catheters were inserted in 454 patients, including 419 (90.9%) for treatment of hydrocephalus and 42 (9.1%) for IIH. The infection rate was 3.3% (15 out of 461 patients) for the entire cohort, 3.6% (15 out of 419 patients) for the hydrocephalus cohort, and 0% for the IIH cohort. There was one death (0.2%) in the hydrocephalus cohort. The infection rate was reduced and sustained at 1.8% for 225 catheters after the topical antiseptic was changed to chlorhexidine (two-sided Fisher's exact test; P = 0.114). CONCLUSION Although infection is the most serious complication of spinal catheter insertion for evaluation of hydrocephalus or IIH, the infection rate can be maintained below 2% with use of chlorhexidine topical antiseptic application, single-dose preprocedural antibiotic administration, and clinical surveillance of the patient. The benefit of cerebrospinal fluid drainage via spinal catheter for normal pressure hydrocephalus outweighs the risks associated with the procedure.

Abstract BACKGROUND: Management of overdrainage complications in shunted patients with idiopathic normal pressure hydrocephalus (INPH) remains a difficult task despite the use of programmable pressure valves. OBJECTIVE: To assess the usefulness of a quick reference table (QRT) algorithm for achieving a suitable initial programmable pressure valve setting in INPH patients who participated in the Study for INPH on Neurological Improvement (SINPHONI). METHODS: One hundred registered patients diagnosed with probable INPH were treated with ventriculoperitoneal shunts using Codman-Hakim programmable valves (CHPVs). In this series, the initial CHPV setting was decided prospectively according to the QRT algorithm. Shunt effectiveness, complications, and the number of CHPV readjustments during follow-up periods were investigated. RESULTS: Eighty patients were considered better than shunt responders (more than 1 point improvement in modified Rankin Scale at any follow-up period). Readjustments of CHPVs within 3 months after treatment with ventriculoperitoneal shunt were performed 56 times in 44 cases (44%, 0.56 times/patient). Low-pressure headache occurred in 9 patients, all of whom improved by readjustment alone. Nontraumatic subdural fluid collections and chronic subdural hematomas occurred in 15 cases (15%); however, most of the cases were subclinical and improved after CHPV readjustments alone. Burr hole irrigation was necessary in only 1 case. CONCLUSION: Use of the QRT algorithm was associated with a decrease in postoperative CHPV readjustments and serious overdrainage complications during the follow-up period. The QRT algorithm is an easy, safe, and effective method for determining the initial CHPV pressure setting in INPH patients.

Cerebrospinal Fluid Shunting

Abstract BackgroundIdiopathic normal pressure hydrocephalus (INPH) is characterized by gait disturbance, urinary incontinence and cognitive decline. Symptoms are potentially reversible and treatment is based on cerebrospinal fluid shunting. The tap test (TT) is used to identify patients that will benefit from surgery. This procedure consists on the withdrawal of 20 to 50 mL of cerebrospinal fluid (CSF) through a lumbar puncture (LP) after which the symptoms of the triad are tested. Improvement in the quality and speed of gait are already recognized but cognitive improvement depends on several factors such as tests used, time elapsed after LP for re-testing, and number of punctures. Serial punctures may trigger similar conditions as external lumbar drainage (ELD) to the organism. ObjectiveThis study aimed to identify how serial punctures affect cognition in order to increase the sensitivity of the test and consequently the accuracy of surgical indication. MethodsSixty-one patients with INPH underwent baseline memory and executive tests repeatedly following the 2-Step Tap Test protocol (2-STT – two procedures of 30 mL lumbar CSF drainage separated by a 24-hour interval). The baseline scores of INPH patients were compared with those of 55 healthy controls, and with intragroup post-puncture scores of the 2-STT. ResultsThe group with INPH had lower performance than the control group in all cognitive tests (RAVLT, Stroop, CFT, FAR-COWA, FAB, MMSE, orientation, mental control), except for the forward digit span test (p = 0.707). After conducting LP procedures, the Stroop test (words, colors and errors), RAVLT (stage A1, A6 and B1), and CFT (immediate and delayed R) scores were equal to those of the control group (p > 0.05). The INPH group presented significant improvement after the first puncture in MMSE (p = 0.031) and in the Stroop Test (points) (p < 0.001). After the second puncture, subjects improved in orientation, MMSE, RAVLT (B1), Stroop (points, words, errors) and CFT (IR). ConclusionProgressive cognitive improvement occurred over the 2-STT and changes were more significant after the second LP in all cognitive domains except for RAVLT (A7). Encephalic alert system ‘arousal’ seems to participate in early improvements observed during 2-STT. The second LP increased the sensitivity of the drainage test to detect changes in cognitive variables, and consequently improved the quality of the method.

Background and aim: Malposition of peripherally inserted central catheters placed at the bedside is a well-recognized phenomenon. We report the success rate of the placement of peripherally inserted central catheters with ultrasound guidance for tip positioning and describe the knacks and pitfalls. Materials and methods: We retrospectively reviewed the medical case charts of 954 patients who received peripherally inserted central catheter procedure. Patient clinical data included success rate of puncture, detection rate of tip malposition with ultrasonography, adjustment rate after X-ray, and success rate of peripherally inserted central catheter placement. Results: The success rate of puncture was 100% (954/954). Detection rate of tip malposition with ultrasonography was 82.1% (78/95). The success rate of ultrasound-guided tip navigation was 98.2% (937/954). The success rate of ultrasound-guided tip location was 98.0% (935/954). Adjustment rate after X-ray was 1.79% (17/952). The final success rate of peripherally inserted central catheter placement was 99.8% (952/954). Conclusion: Ultrasound guidance for puncturing and tip positioning is a promising option for the placement of peripherally inserted central catheters. Ultrasound guidance could dispense with radiation exposure and the transfer of patients to the X-ray department.

Pressure Headache

Post-dural-puncture headache (PDPH) is a consequence of neuraxial anesthesia, diagnostic lumbar puncture, intrathecal drug delivery systems, or any other technique involving dural trespass. The spinal headache results from a dural puncture that leads to cerebrospinal fluid (CSF) leakage from the subarachnoid space to the epidural space, culminating in intracranial hypotension and development of a low-pressure headache. A key element of PDPH is an increase in pain severity upon a change in position from supine to upright, which corresponds to a gravity-induced influence on CSF pressure dynamics. Age, sex, and design of the needle used correlate with the risk of headache. Sometimes, the headache resolves spontaneously. At other times, conservative treatment or aggressive measures are required to terminate the pain. An autologous epidural blood patch is an established way preventing or treating PDPH. A careful history must be obtained to identify other causes of headache before the blood patch is attempted.
