Prediction of Hypertrophy of Liver Segments 2 and 3 After Right Portal Vein Embolization (RPVE) and Extended Right Hepatectomy

 

Patient selection: extended right hepatectomy with right portal vein embolization (RPVE)

 

Outcome: percentage hypertrophy in segments 2 and 3 following therapy

 

Parameters:

(1) body mass index (BMI) over range from 16 to 48 kg per square meter

(2) history of previous hepatectomy

(3) 2 stage porcedure (RPVE followed by right hepatectomy, usually performed in patients with bilateral colorectal liver metastases)

(4) segment 4 embolization

 

points for BMI =

= 150 - (3.125 * (BMI))

Parameters	Findings	Points
previous hepatectomy	no	52.6
	yes	0
2-stage procedure	no	46
	yes	0
segment 4 embolization	no	0
	yes	33.6

 

total score =

= SUM(points for all 4 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 232.2

• The higher the score the greater the hypertrophy in segments 2 and 3.
