Angiography with selective embolization has become an accepted method of treating posterior epistaxis that is not controlled with conservative measures. The authors reviewed 112 cases of patients who had received selective angiographic embolization for refractory epistaxis from January 1990 to December 1995. There were 114 embolizations over this 5-year period. The immediate success rate was 93%, with long-term success achieved in 88% of patients. The overall complication rate was 17%, with the long-term morbidity rate less than 1%. Selective angiographic embolization is a safe and effective method that should be considered in the treatment of refractory epistaxis.
We reviewed 37 consecutive, hemodynamically stable patients (16 adults, 21 children) who had splenic injuries diagnosed by computed tomography (CT) scan to compare the CT evaluation with operative assessment of injury and eventual treatment. Computed tomographic scans and operative findings were graded by a splenic injury scoring system. Two patients were classified as having grade 1, 21 as grade 2, 11 as grade 3, and 3 as grade 4 splenic injuries. Computed tomography underestimated the degree of injury in 9 of 17 (53%) operated patients (mean CT score, 2.6; mean operative score, 3.3; p less than 0.01). Six of sixteen adults and 19 of 21 children were intentionally treated by observation. There were 5 treatments failures (20%), 3 due to bleeding and 1 each due to pancreatic injury and splenic abscess. The failure rate of observation was lower in children (16%) than in adults (33%), even though children had a higher Splenic Injury Score (2.4 versus 1.8). Patients who underwent an operation received twice as much blood as the observed group. There was no significant difference in Injury Severity Score or total fluid requirements between operated and observed patients. Operations increased in frequency in both adults and children as the injury score increased. This experience suggests that CT scan accurately determines the presence of splenic injury but commonly underestimates its severity. While children with grades 1 through 3 injuries are likely to be treated successfully with observation, adults who have more minor splenic injuries often fail observation and may be treated better by prompt operation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
