Echographic assessment of visceral perfusion under intra-aortic balloon pump support
Authors' conclusion
Visceral flow pattern was a biphasic pulse under IABP support, and total visceral flow was significantly increased. However, a narrow abdominal aorta can be a risk for decreased visceral perfusion.
Study context
- Population
- Patients treated with intra-aortic balloon pump (IABP) in a single cardiovascular center
- Participants
- 33 patients
- Exposure
- Visceral perfusion with vs without IABP counterpulsation
- Outcome
- Visceral perfusion (blood flow in visceral branches by transabdominal echography) under IABP support
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Abdominal aorta flow significantly increased
from 15.4 [12.1-30.4] ml/beat to 28.0 [16.0-48.1] ml/beat
P < 0.001
Celiac artery flow significantly increased
from 6.4 [3.6-11.4] ml/beat to 9.5 [3.4-16.6] ml/beat
P < 0.001
Superior mesenteric artery flow significantly increased
from 6.6 [4.7-9.1] ml/beat to 9.9 [4.3-12.6] ml/beat
P < 0.001
Left renal artery flow significantly increased
from 2.4 [1.8-5.2] ml/beat to 4.3 [3.2-6.8] ml/beat
P = 0.002
Observational data: associations, not effects.
Further findings

- Patients with decreased flow
- 8 patients (24.2%)
Aortic diameter at celiac trunk level, increased vs decreased visceral flow
- Aortic diameter significantly smaller (as printed)
- 22.5 [20.8-24.0] mm vs. 20.5 [19.6-22.3] mm, P = 0.002
