1 ADVANCING SCIENCE, ENHANCING LIFE Role of Arterial Embolization in Non-Operative Management of Splenic Injuries Jamaica Hospital Trauma Conference July 21 st, 2014 Greg Eckenrode

2 Management of Traumatic Spleen Injuries Historically, nearly all splenic injuries were managed operatively Non-operative management developed in the pediatic population in the late 1960s Increasing prevalence in adult population since the 1980s – Currently 50-70% of splenic injuries Stein DM, Scalea TM J Intensive Care Med. 2006;21(5):296.

3 Operative Management Hemodynamically unstable patients with evidence of abdominal bleeding – Positive FAST or DPA/DPL Patients requiring abdominal exploration for other injuries – Intraperitoneal free air – Signs of peritonitis

4 Operative Management Hemodynamically stable patients – CT findings of contrast extravasation or vascular blush – High grade injuries (generally IV-V) – Age > 55 – Unable to safely observe patient

5 Conventional Non-Operative Management Admit to monitored care setting Bed rest, NPO Serial Hgb/Hct every 6 hours for 24 hours Frequent vital signs, serial abdominal exams

6 Splenic Angiography and Embolization First applied to traumatic splenic injuries in 1995 Multiple techniques – Distal selective – Proximal – Both Intended to improve success of non-operative management

7 Clinical Questions Does splenic artery angiography and embolization improve non-operative management outcomes? Which patients should undergo angiography and embolization?

8 Western Trauma Association 4 L1 trauma centers in the United States 155 patients who underwent angiography and embolization for pseudoaneurysm, active bleeding on CT, significant hemopertoneum, and high grade injuries Compared against the results of the Eastern Trauma Association study, which used conventional observation

9 Comparison Results Haan, et al; J Trauma Mar;56(3):542-7.J Trauma.

10 Ullevaal University Hospital: 2006 In 2002, implemented policy that all patients with splenic injury Grades III-V or ongoing bleeding underwent arterial embolization Compared to all splenic injuries from , when arterial embolization was no performed at the hospital Gaardner, C, et al; J Trauma Jul;61(1):192-8J Trauma.

11 Study Outcomes

12 Complications

13 Multicenter Variation: 2010 Compared 4 L1 trauma centers with variation in rates of splenic artery embolization in non- operative management Rates ranged from 19% to 1% Compared rates of splenic salvage and non- operative failure Bannerjee, et al; J Trauma Acute Care Surg Jul;75(1):69-74

14 Population Comparison Bannerjee, et al; J Trauma Acute Care Surg Jul;75(1):69-74

15 Management Comparison Bannerjee, et al; J Trauma Acute Care Surg Jul;75(1):69-74

16 Splenic Salvage Rate Bannerjee, et al; J Trauma Acute Care Surg Jul;75(1):69-74

17 Wake Forest Single site L1 Trauma Center Prior to 2010, angiography and embolization performed for CT contrast blush Starting in 2010, prospectively performed angiography and embolization on all Grade III- IV splenic injuries Compared non-operative failure rates against recent historical controls from period Miller, et al; J Am Coll Surg Apr;218(4):644-8J Am Coll Surg.

18 Study Group Comparison Miller, et al; J Am Coll Surg Apr;218(4):644-8J Am Coll Surg.

19 Study Results : Non-operative failure rate of 5% – Failure rate of 25% in 16 protocol deviations (p=0.02) : Non-operative failure rate of 15% (p=0.04)

20 Conclusions In historical comparisons, patients with splenic injuries who are candidates for non- operative management have better outcomes when SAE is utilized Centers which perform a higher rate of SAE have higher rates of spelic salvage and lower rates of non-operative management failure

21 Conclusions Centers which implement a standard protocol mandating SAE for non-operative splenic injuries experience decreased rates of of non- operative failure and increased rates of splenic salvage

22 Future Directions No prospective, head-to-head randomized clinical trial of SAE in non-operative splenic injuries Limited data with respect to cost effectiveness

23 Splenic Injury Grading Grade I: – Hematoma: Subcapsular, < 10% of surface area – Laceration: Capsular tear < 1 cm depth Grade II – Hematoma: Subcapsular, % of surface area – Laceration: Capsular tear cm depth not involving trebecular vessel

24 Splenic Injury Grading Grade III – Hematoma Subcapsular, > 50% of surface area Subcapsular, expanding Ruptured subcapsular or parenchymal Intraparenchymal > 5cm – Laceration > 3cm depth Involving trabecular vessel

25 Splenic Injury Grading Grade IV – Laceration: segmental or hilar vessels with > 25% devascularization Grade V – Hematoma: shattered spleen – Laceration: total devascularization
