Risk Score of Revel-Vilk et al for Central Venous Catheter Related Occlusion and Deep Vein Thrombosis in a Pediatric Patient with Cancer

Description

Revel-Vilk et al evaluated risk factors for complications of a central venous catheter in pediatric patients with cancer. These can help to identify a patient who may benefit from more aggressive management. The authors are from Hadassah Hebrew-University, Schneider Children's Medical Center, Tel Aviv University, and Sheba Medical Center in Israel.

Patient selection: pediatric patient with central venous catheter (CVC) inserted for chemotherapy

Outcome: CVC-related deep vein thrombosis and occlusion

Parameters for catheter occlusion:

(1) type of catheter

(2) location of tip

(3) family history of thrombosis

Parameter	Finding	Points
type of catheter	peripherally inserted central catheter (PICC)	0
	port-a-cath	1
	Hickman	2
location of tip	right atrium (RA)	0
	RA/ SVC	0
	superior vena cava (SVC)	1
family history of thrombosis	no	0
	yes	1

total score =

= SUM(points for all 3 parameters)

Interpretation:

• minimum score: 0

• maximum score: 4

• The initial score was converted to a final score based on table below.

Initial Score	Final Score	Occlusion Risk
0	0	low
1 or 2	1	intermediate
3 or 4	2	high

Risk factors for catheter-related deep vein thrombosis:

(1) insertion in an angiography suite (vs operating room)

(2) both occlusion and infection

(3) family history of thrombosis

(4) PICC line
