Results
Demographics of the pump thrombosis group (n=8) and the selected control group (n=10) did not differ significantly from the whole patient populations (PT group age: 60.4±8.5y,
Male n=7/8,
BMI: 26.1±4.2 kg/m²,
NT group age: 59.5±12.9y,
Male n=8/10,
BMI: 25.5±3.6 kg/m²,
whole population age: 59.9±10.8y,
Male n=3/18,
BMI: 25.7±3.8 kg/m²).
The angle α (as defined in Fig 3) was different in the PT group compared to NT patients (PT ‑22.0±4.7° vs.
NT ‑1.2±7.5°; p= 0.006).
For the angle β differences were found,
albeit without statistical significance (PT -9.3±15.1° vs NT -28.9±8.6°; p=0.103) (Fig.
5).
Additionally,
the angle α correlated well to the pump area as measured from the frontal X-Ray images ρ =‑0.922,
p=0.003 (Fig. 5).
In the frontal X-Rays the minor axis of the elliptical projection of the pump body showed significant differences between the PT and NT groups (PT 41.3±4.8 mm vs NT 34.9±6.0 mm,
p=0.026) and in the lateral X-Rays the pump body area was significantly smaller for the PT group (PT 2006±77 mm² vs NT 2138±132 mm²,
p=0.042) (see Table 1).
