Flashcards in Splenic Salvage procedures, Trauma Deck (17):
1

What are the advantages of nonoperative management of splenic injuries?

Avoiding immunologic effects and the risks of laparotomy (intraabdominal injuries to pancreas), asplenia (risk of OPSI)

2

What is the prime determinant in operative versus nonoperative management in splenic injury?

Hemodynamic stability

3

What is a grade I splenic injury?

Hematoma with subscapular, <10% surface

4

What is a grade II splenic injury?

Subcapsular hematoma, 10-50% surface area, intraparenchymal hematoma, <5cm;
Laceration: Capsular tear from 1-3cm parenchymal depth

5

What is a grade III splenic injury?

Hematoma - subcapsular >50% surface area or expanding, ruptured or parenchymal hematoma; or intraparenchymal hematoma >5cm or expanding
Laceration >3cm parenchymal depth or involving trabecular vessels.

6

What is a grade IV splenic injury?

Laceration involving segmental or hilar vessels producing major (>25%) devascularization

7

What is a grade V splenic injury?

Completely shattered spleen, or hilar vascular injury with devascularized spleen

8

General indications for angioembolization for splenic injury

Controversial topic, but in general a contrast blush or pooling on CT, a higher grade injury (III +), persistent tachycardia and declining hematocrit are indications

9

Which criteria increase failure rate of angioembolizaion?

Presence of an arteriovenous fistula on CT scan, age >55, hemodynamic instability

10

Criterion for Nonoperative management of blunt splenic injury

Hemodynamic stability, absence of additional injuries requiring operative intervention, transfusion fewer than 2 units

11

At the time of initial injury, should chemical DVT prophylaxis be used in patients undergoing nonoperative treatment for blunt splenic injury?

No, chemical prophylactic anticoagulation is contraindicated.

12

What is the general consensus regarding resuming normal activities after blunt splenic trauma?

After 2-4 months

13

What is the most common cause of failure of nonoperative management?

Bleeding within 4 days on therapy

14

When is repeat imaging recommending for high grade injuries managed nonoperatively? (grades III-IV)

CT scan after 4-6 weeks

15

If a grade 1 or 2 splenic laceration is encountered during abdominal exploration for another indication, what is the preferred method of splenic repair?

Direct application of electrocautery or argon beam coagulator

16

If a grade 3 splenic laceration is encountered, and patient is stable, what are common options for splenorrhapy?

Manual compression, and pledgeted sutures to repair injury or mesh splenorrhapy over injured portions of the spleen.

17

In a patient with an aortic injury and an associated splenic injury, what is the operative approach?

First, splenectomy, then address the more complicated issue.
