Risk Factors of Cousins et al for Accelerated Growth of an Aneurysm of the Popliteal Artery

Description

Cousins et al identified risk factors for an accelerated rate of growth of an aneurysm involving the popliteal artery. These can help to identify a patient who may benefit from closer monitoring and more aggressive management. The authors are from Eastern Virginia Medical School.


Patient selection: popliteal artery aneurysm

 

Risk factors for accelerated growth:

(1) diameter >= 20 mm

(2) presence of luminal thrombus

(3) atrial fibrillation

 

The risk of accelerated growth increases with the number of risk factors present.

 

In addition, a growth rate > 1.22 mm per year since initial diagnosis is associated with interventions.

 

growth rate in mm per year =

= ((diameter now) - (diameter at diagnosis)) / (((date now) - (date diagnosis)) / 365)
