RESUMO
Inferior vena cava filters are commonly encountered devices on diagnostic imaging that were highlighted in a 2010 Food and Drug Administration safety advisory regarding their complications from long-term implantation. The Predicting the Safety and Effectiveness of Inferior Vena Cava Filters (PRESERVE) trial is an ongoing after-market study investigating the safety and utility of commonly utilized filters in practice today. While most of these filters are safe, prompt recognition and management of any filter-associated complication is imperative to prevent or reduce the morbidity and mortality associated with them. This review is aimed at discussing the appropriate utilization and placement of inferior vena cava filters in addition to the recognition of filter-associated complications on cross-sectional imaging. An overview of the PRESRVE trial filters is also provided to understand each filter's propensity for specific complications.

PURPOSE: The aim of this study was to expand on our previous report of 115 patients after more than a decade-long experience using incision and loop drainage for pediatric subcutaneous abscess management. This report comprises the largest consecutive series of pediatric abscess patients from a single institution ever recorded. METHODS: A retrospective study was performed of all pediatric patients who underwent incision and loop drainage of subcutaneous abscesses at our institution between January 2002 and December 2014. TECHNIQUE: Two sub 5mm incisions were made at the periphery on the abscess. The abscess cavity was probed to break down loculations and drain pus. The abscess cavity was irrigated with normal saline. A loop drain was passed through one incision and brought out through the other. A simple absorbent dressing was applied over the drain. RESULTS: Five hundred seventy-six consecutive patients underwent loop drainage procedures. Mean values are as follows: age, 3.84years; duration of symptoms, 6.17days; postoperative length of stay (with 4 outliers excluded), 0.69days; drain duration, 8.38days; and number of postoperative visits, 1.28. Twenty-six patients had reoperations (4.5%), 2 of which were planned staged excisions of pilonidal cysts and 1 because of accidental home removal. CONCLUSIONS: Micro-incisions and loop drainage is a safe and effective treatment modality for subcutaneous abscesses in children. The findings eliminate the need for repetitive wound packing and simplify postoperative wound care. Loop drainage offers shorter time to discharge, lower recurrence rates, and minimal scarring. Additionally, there is expected cost reduction. We recommend this minimally invasive procedure to be the standard of care for subcutaneous abscesses in children. TYPE OF STUDY: Treatment study - retrospective review. LEVEL OF EVIDENCE: Level IV - case series with no comparison group.
