Splenic embolization remains a valuable technique in splenic salvage, especially in higher grade injuries. Complications are common but do not seem to affect outcome.
Splenic embolization is a valuable adjunct to splenic salvage in our experience, allowing for the increased use of nonoperative management and higher salvage rates for American Association for the Surgery of Trauma splenic injury grades when compared with prior studies. Main coil embolization has a similar salvage rate when compared with other angiographic techniques. An arteriovenous fistula as a CT finding was predictive of a 40% nonoperative failure rate.
Vascular injury increases with splenic injury grade. Embolization improves nonoperative salvage rates to 92%, even with high-grade injuries. Ten percent of patients require additional therapy including "second-look" angiography. A significant portion of patients with negative screening angiograms (10%) required either embolization or laparotomy to control delayed hemorrhage.
Shock, evisceration, and peritonitis warrant immediate LAP after AASW. Patients without these findings can be safely observed for signs or symptoms of bleeding or hollow viscus injury. To limit the number of hospital admissions, we propose a uniform strategy using LWE to ascertain the depth of penetration; the patient may be safely discharged in the absence of peritoneal violation. Peritoneal penetration, absent evidence of ongoing hemorrhage or hollow viscus injury, should not be considered an indication for LAP, but rather an indication for admission for SCAs. We suggest that a prospective multicenter trial be performed to document the safety and cost-effectiveness of such an approach.
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.
