Abstract No. 124 Sequelae of Splenic Embolization by Age: A Retrospective Analysis

SAE is a widely used intervention to manage traumatic splenic hemorrhage and hypersplenism from varying diseases. Previous studies have indicated that older adult patients receiving SAE have a higher incidence of major complications following intervention. SAE complication rates have also been shown to be increased when performed distally. [3]. Surgical studies demonstrate higher rates of complications after laparoscopic splenectomy in older adults. The sequelae of SAE and associated complications, length of hospital stay (LOH), and need for splenectomy may not differ between age groups . To our knowledge, this is one of the first studies to analyze characteristic differences in SAE associations among non–older adult and older adult patients >65 years of age. This is a single-center retrospective review spanning December 2018 to January 2022 of SAE in patients with confirmed splenic injury from traumatic and atraumatic causes. Procedural and post-procedural data including age, LOH, traumatic or atraumatic mechanism of splenic injury, proximal or distal embolization, and complications were collected. Data were stratified between patients ≥ 65 years old and < 65 years old. 93 patients who underwent SAE were analyzed for associated complications and stratified to groups in order to account for age. The older adult group (n = 20) and non–older adult group (n = 73) were compared to assess complication rate, SAE complication and LOH (days). Complications noted in the older adult group included splenectomy (n= 4), rebleed (n= 3), and death (n= 1). Non–older adult group complications included splenectomy (n= 8), rebleed (n= 16), and death (n= 2). These results are referenced in Table 124.1. SAE whether performed distal or proximal is a safe and effective way to manage traumatic splenic injury or hypersplenism in patients ≥ 65 years old. When compared to the non–older adult group, the older adult group exhibited no significant statistical difference when it came to LOH, complication rates, rebleeding rates, and need for splenectomy after SAE. Regardless of splenic laceration grade and etiology (traumatic or atraumatic), distal or proximal SAE should be considered in patients ≥ 65 years of age.
