RESUMEN
PURPOSE: To assess the safety and efficacy of the posthemostasis use of an inflatable adhesive external compression device (SafeGuard) following angiography in children performed under general anesthesia. MATERIALS AND METHODS: Medical records of 74 children (43 females) with a mean age of 8.9 years (range, 0.4-18.0 years) and mean weight of 44.0 kg (range, 7.3-115.7 kg) in whom an inflatable adhesive external compression device was used for maintaining hemostasis following angiography under general anesthesia were retrospectively reviewed. After establishing hemostasis with manual compression, the device was applied and inflated over the arteriotomy. The patients were assessed for access-related adverse events in the recovery unit and during postprocedural follow-up. RESULTS: The inflatable adhesive external compression device was utilized to maintain hemostasis following 181 angiography procedures. The mean length of the procedure was 396 minutes. The common femoral artery (n = 170, 93.9%) was the most common access, using 4-5-F vascular sheath (n = 118, 65.2%) or 3-5-F sheathless (n = 8, 12.7%) catheters. The mean time to deflation was 93 minutes. There were no adverse events other than minor bleeding from the arteriotomy after deflation (n = 2, 1.1%) and early deflation of the device because of pain (n = 1, <1%). Follow-up ultrasonography (n = 109 procedures, 60.2% at a mean follow-up of 2.2 years) demonstrated patency of the access artery. CONCLUSIONS: The use of an inflatable adhesive external compression device following angiography in children to maintain hemostasis during the emergence phase of anesthesia and recovery period is safe and effective. The use of this simple device may reduce the need for postprocedural sedation and facilitate early discharge.

OBJECTIVE: To describe the clinical, radiologic, and histopathologic features of "congenital disseminated pyogenic granuloma" involving various organs with high morbidity related to cerebral hemorrhagic involvement. STUDY DESIGN: We searched the database of the Vascular Anomalies Center at Boston Children's Hospital from 1999 to 2019 for patients diagnosed as having multiple vascular lesions, visceral vascular tumors, congenital hemangiomatosis, multiple pyogenic granulomas, or multiple vascular lesions without a definite diagnosis. A retrospective review of the medical records, photographs, histopathologic, and imaging studies was performed. Only patients with imaging studies and histopathologic diagnosis of pyogenic granuloma were included. RESULTS: Eight children (5 male, 3 female) had congenital multifocal cutaneous vascular tumors. Lesions also were found in the brain (n = 7), liver (n = 4), spleen (n = 3), muscles (n = 4), bone (n = 3), retroperitoneum (n = 3), and intestine/mesentery (n = 2). Less commonly affected were the spinal cord, lungs, kidneys, pancreas, and adrenal gland (n = 1 each). The mean follow-up period was 21.8 months. The cerebral and visceral lesions were hemorrhagic with severe neurologic sequelae. The histopathologic diagnosis was pyogenic granuloma with prominent areas of hemorrhage and necrosis. The endothelial cells had enlarged nuclei, pale cytoplasm and were immunopositive for CD31 and negative for D2-40 and glucose transporter 1. CONCLUSIONS: Congenital disseminated pyogenic granuloma is a distinct multisystemic aggressive disorder that primarily affects the skin, brain, visceral organs, and musculoskeletal system. Differentiation of this entity from other multiple cutaneous vascular lesions is critical because of possible cerebral hemorrhagic involvement.

OBJECTIVE: Following percutaneous liver biopsy performed at our institution on an outpatient basis, children traditionally were observed for 4âhours then discharged after verifying a stable hematocrit level. In June 2015, we adopted a quality improvement project with shorter 2-hour observation for patients with no known risks and the hematocrit test was abandoned.The purpose of this study is to evaluate the clinical and economic outcomes of early discharge of children following liver biopsy. METHODS: We analyzed data on 2 groups of children who underwent ultrasound-guided nontargeted core needle liver biopsy performed on outpatient basis. Group A (100 procedures with 4-hour postprocedural observation time and hematocrit test) was compared with group B (100 procedures with 2-hour observation without hematocrit test). RESULTS: Group A consisted of 92 patients (43 boys; 49 girls) with a mean age of 11.1 years and mean weight of 52.6âkg. Group B had 92 patients (47 boys; 45 girls) with a mean age of 8.9 years and mean weight of 40.5âkg. The mean length of observation was 281 minutes (range 204-540 minutes) and 147 minutes (range 86-332 minutes) for groups A and B, respectively. The mean recovery charges were reduced by 35% per procedure in group B. The tissue obtained was sufficient for pathologic diagnosis in all procedures. There were no biopsy-related complications in either group. CONCLUSIONS: Enhanced recovery with early discharge of low-risk children after 2-hour observation following percutaneous liver biopsy can be safely implemented without adversely affecting the outcome. Shorter postbiopsy observation can be cost-saving and may potentially improve patient satisfaction.

BACKGROUND: Fibro-adipose vascular anomaly (FAVA) is a complex vascular malformation that typically presents with persistent pain, discomfort, contracture and other disabling symptoms. There are no minimally invasive treatment options to effectively control these symptoms. Image-guided percutaneous cryoablation, which has been used to control pain in people with cancer, could be used for similar indications in FAVA. OBJECTIVE: To assess the role of image-guided percutaneous cryoablation for control of symptoms in FAVA lesions. MATERIALS AND METHODS: We conducted a retrospective cohort study of 20 children and young adults with FAVA who underwent percutaneous cryoablation at 26 sites, from September 2013 to August 2015. The outcome was based on the brief pain inventory scoring (BPI), concurrent symptoms, clinical response and patient satisfaction. RESULTS: After cryoablation there was significant improvement in pain, which dropped by 3 points (pain now) to 3.7 points (pain in the last 24 h). Most patients indicated that pain interfered less in their everyday social life. Concurrent symptoms like swelling, physical limitations and skin hyperesthesia also improved. Clinical response was greatest at 2-5 months follow-up after cryoablation, with acceptable patient satisfaction thereafter. Technical response was 100%. There were no major complications. CONCLUSION: Image-guided percutaneous cryoablation is a safe and effective option for treatment of symptomatic FAVA lesions.

OBJECTIVE: Clinical manifestations of blue rubber bleb nevus syndrome (BRBNS) and multifocal venous malformation (MVM) vary depending on the location of the lesions. The aim of this study was to assess the risk of developing CSF leaks in patients with epidural venous malformations (VMs). METHODS: The authors retrospectively investigated the relationship between the development of a CSF leak and the presence of epidural VMs. RESULTS: Nine patients (5 females) had epidural VMs and presentation that was confirmatory or suggestive of a CSF leak: 4 had BRBNS, 4 had MVMs, and 1 had a solitary VM. Of 66 patients with BRBNS, clinical and imaging features of CSF leak were noted in 3 (4.5%) with epidural VMs at the age of 11-44 years. A fourth patient had suggestive symptoms without imaging confirmation. An epidural blood patch was ineffective in 2 patients, both with more than one source of leakage, requiring surgical repair or decompression. Symptomatic downward displacement of the cerebellar tonsils was noted in 3 patients with MVM and 1 with a solitary VM; 3 required surgical decompression. CONCLUSIONS: These findings suggest an increased risk of CSF leak in patients with epidural VM, including BRBNS, MVMs, and solitary VMs. Awareness of the association between epidural VM and CSF leakage may facilitate earlier diagnosis and therapeutic intervention.
RESUMEN
PURPOSE: To describe the use of the internal mammary vein as an alternative access for central venous catheters. METHODS: We performed a retrospective review of patients who underwent placement of central venous catheters via the internal mammary vein. Patient demographics, indication for venous access, technical success, catheter type, dwell time and indication for exchange or removal were recorded. RESULTS: Placement of central venous catheters via the internal mammary vein was attempted in 11 patients including 8 children (4 males, mean age 5.7 years) and 3 adults. The most common indication was parenteral nutrition in patients with intestinal failure (7/11). Initial needle access of the vein was successful in all patients. Catheter placement was successful in 9 and unsuccessful in 2 patients due to occlusion of the superior vena cava. There were no immediate complications. A total of 20 catheters of various sizes (3-14.5 French) and lengths (8-23 cm) were either placed (n = 12) or exchanged (n = 8). The most common indications for catheter exchange were poor function and malposition (7/8). Four catheters were removed for infection and 4 were accidentally removed. The mean dwell time was 141 days (range 0-963 days) per catheter for a total of 2829 catheter days. The total mean dwell time per patient, including primarily placed and exchanged catheters, was 314 days (range 5-963 days). CONCLUSIONS: The internal mammary vein may provide a safe alternative route for patients who have lost their traditional access veins.
