RESUMEN
BACKGROUND: Persistent headaches and migraines are common in pediatrics with various treatment options. The sphenopalatine ganglion (SPG) has been identified as communicating with the parasympathetic autonomic nervous system and pain receptors. In adults, SPG block is an established treatment but there is no published literature in pediatrics. OBJECTIVES: The purpose of this study is to analyze the SPG block in pediatrics. STUDY DESIGN: Retrospective, single-center study. SETTING: This study was conducted at Phoenix Children's Hospital in Phoenix, Arizona. METHODS: A comprehensive review of patient charts from 2015-2018 of all pediatric SPG blockades performed by interventional radiology were included in the analysis. Utilizing fluoroscopic guidance, a SphenoCath was inserted into each nostril and after confirming position, and 4% lidocaine injected. Pre- and postprocedural pain was assessed using the Visual Analog Scale (VAS). Immediate and acute complications were documented. RESULTS: A total of 489 SPG blocks were performed in patients between ages 6 and 26 years who were diagnosed with migraine or status migrainosus. One hundred percent technical success was achieved with mean reduction of pain scores of 2.4, which was statistically significant (P < 0.0001). There were no immediate or acute complications. LIMITATIONS: Results of this study were based on retrospective study. The use of VAS may be subjective, and the need of a prospective study may be necessary. CONCLUSIONS: With 100% technical success, statistically significant pain reduction, and no complications, we support SPG block in the pediatric population as a simple, efficacious, and safe treatment option for refractory headaches. It is routinely performed in less than 10 minutes and commonly negates the need for inpatient headache pain management. Given its minimal invasivity, we support the use of SPG blockade as a therapeutic treatment in refractory pediatric migraines as it reduces the need for intravenous medications, prolonged pain control, or hospital admission.

BACKGROUND: Spinal muscular atrophy (SMA) is an autosomal-recessive neuromuscular disorder resulting in progressive muscle weakness. In December 2016, the U.S. Food and Drug Administration approved the first treatment for SMA, a drug named nusinersen (Spinraza) that is administered intrathecally. However many children with SMA have neuromuscular scoliosis or spinal instrumentation resulting in challenging intrathecal access. Therefore alternative routes must be considered in these complex patients. OBJECTIVE: To investigate routes of drug access, we reviewed our institutional experience of administering intrathecal nusinersen in all children with spinal muscular atrophy regardless of spinal anatomy or instrumentation. MATERIALS AND METHODS: We reviewed children with SMA who were referred for intrathecal nusinersen injections from March to December 2017 at our institution. In select children with spinal hardware, spinal imaging was requested to facilitate pre-procedure planning. Standard equipment for intrathecal injections was utilized. All children were followed up by their referring neurologist. RESULTS: A total of 104 intrathecal nusinersen injections were performed in 26 children with 100% technical success. Sixty procedures were performed without pre-procedural imaging and via standard interspinous technique. The remaining 44 procedures were performed in 11 complex (i.e. neuromuscular scoliosis or spinal instrumentation) patients requiring pre-procedural imaging for planning purposes. Nineteen of the 44 complex procedures were performed via standard interspinous technique from L2 to S1. Twenty-two of the 44 complex procedures were performed using a neural-foraminal approach from L3 to L5. Three of the 44 complex procedures were performed via cervical puncture technique. There were no immediate or long-term complications but there was one child with short-term complications of meningismus and back pain at the injection site. CONCLUSION: Although we achieved 100% technical success in intrathecal nusinersen administration, our practices evolved during the course of this study. As a result of our early experience we developed an algorithm to assist in promoting safe and effective nusinersen administration in children with spinal muscular atrophy regardless of SMA type, abnormal spinal anatomy and complex spinal instrumentation.

BACKGROUND: Acalculous cholecystitis is known to develop in critically ill patients without cystic duct obstruction. In the past, treatment for acalculous cholecystitis has been cholecystectomy; however, many children who are critically ill are Percutaneous cholecystostomy is likely the procedure of choice in this subgroup of patients. OBJECTIVE: To assess the safety and effectiveness of percutaneous cholecystostomy in critically ill and immune-compromised children with acalculous cholecystitis. MATERIALS AND METHODS: Retrospective review of immune-compromised and critically ill children who underwent percutaneous cholecystostomy between 2006 and 2013. Diagnostic imaging performed included ultrasound, CT and hepatobiliary scintigraphy. Every percutaneous cholecystostomy was performed using imaging guidance. RESULTS: Ten critically ill and immune-compromised children with acalculous cholecystitis underwent percutaneous cholecystostomy. Seven boys and 3 girls, ranging in age from 10 months to 15 years 8 months, were treated. Six of the immune-compromised children had received a bone marrow transplant for leukemia (5 children) or severe combined immunodeficiency (SCID) (1 child), and ranged from 18 to 307 days post bone marrow transplant at the time of their percutaneous cholecystostomy. Of the remaining four immune-compromised children with acalculous cholecystitis who underwent percutaneous cholecystostomy, two had leukemia, one had SCID and lymphoma, and the fourth was undergoing treatment for undifferentiated germ cell tumor. The 10 percutaneous gallbladder drains were placed using a transhepatic approach, except one unintentional transperitoneal approach. There were no complications. Three gallbladder drains were removed in Interventional Radiology. Those three patients had a return to normal gallbladder function and didn't require cholecystectomy. Two drains were removed during cholecystectomy and another as an outpatient. Four patients died in the hospital due to multiorgan system failure, with indwelling gallbladder drains. CONCLUSION: Percutaneous cholecystostomy is a safe procedure in immune-compromised and critically ill children with acalculous cholecystitis. Percutaneous cholecystostomy may obviate the need for future cholecystectomy.

BACKGROUND: In the pediatric population, obtaining venous access in high-risk neonates, severely ill children with cardiac anomalies or very young children (<10 kg) can be very challenging. In the literature to date, the greater saphenous vein has not been primarily used by interventional radiologists as an entry site for venous access in children. OBJECTIVE: To demonstrate the utility and effectiveness of using the greater saphenous vein as a venous access site for the placement of peripherally inserted central catheters in children. MATERIALS AND METHODS: This is a retrospective study from a large tertiary care children's hospital from November 2010 to August 2012. Peripheral insertion of central venous catheters (PICC) using the greater saphenous vein was attempted in 86 children ranging in age from 3 days to 17 years (mean: 1.8 years). Indications included congenital heart disease, urinary tract infection, intravenous access, pneumonia, meningitis, total parenteral nutrition, sepsis and other infections. All procedures were performed by interventional radiologists. No insertion-related complications were identified. There was no follow-up planning, but no mechanical or infectious complications were brought to our attention. RESULTS: Of the 86 patients in whom PICC placement was attempted, placement was successful in 67 (78%). Forty-two PICCs were placed in the greater saphenous vein at the thigh level using US guidance and 25 at the ankle level using anatomical landmarks. The mean weight of the 67 patients who underwent successful placement was 9.98 kg, with 51 (76%) weighing <10 kg. The mean vessel diameter in placement failures was 1.35 mm compared to 1.83 mm in successful placement. Inability to obtain venous access was the cause of failure in all thigh access sites while inability to advance the catheter centrally was the cause of failure for all ankle access sites. A total of 1,060 catheter days (with a maximum dwell time of 97 days in one patient) were reviewed without complication. CONCLUSION: In children, the greater saphenous vein provides a safe, suitable alternative for venous access, particularly in very young children (<10 kg) and in a select group of older children who are not mobile. In the lower extremities, greater saphenous venous puncture and access may be a preferred initial access site in small children to preserve future venous access.
