“…In cows with uterine torsion ≥360°, vascular compromise develops within the uterus, broad ligament, and mesovarium, which results in edematous swelling of the uterine wall [3, 7, 9]. Further aggravation of the torsion causes fetal death, thickening of the uterus, and uterine necrosis in protracted cases [10]. A cow with similarly severe uterine torsion showed thickening of the uterine wall, congestion, edema, necrosis, and thrombus on necropsy and histopathology [9].…”

In this study, we aimed to elucidate the utility of transrectal ultrasonography (TRUS) and blood lactate concentration (bLac) measurement to diagnose cows with severe uterine torsion. We investigated the association of TRUS and bLac measurement with macroscopic findings on laparotomy for severe uterine torsion in nine cows. We found that an increased ultrasonographic cross-sectional thickness (15–25 mm) and multiple hypoechogenic areas corresponded to macroscopic vascular compromise in the uterus on laparotomy. In addition, bLac was elevated (≥5.0 mmol/l) in cows showing uterine necrosis on laparotomy. A combined diagnostic approach with TRUS and bLac measurement enables assessment of the uterine vascular status and has utility for selecting the treatment option (including laparotomy) and predicting the outcomes.

“…Furthermore, there is a risk of post-correction mortality due to ischemia-reperfusion injury in cows with torsion accompanied by uterine necrosis [14]. Thus, it is necessary that procedures including possible hysterectomy [22] be considered for those animals. In addition, a bLac of ≥6.5 mmol/ l may be a sign of poor prognosis.…”

In order to determine blood lactate concentrations (bLac) and their validity as a diagnostic marker in bovine uterine torsion, blood samples were taken from 54 Holstein cows with uterine torsion before the correction of torsion. bLac in a group of cows with and without uterine necrosis were 15.0 and 3.0 mmol/l, respectively (P<0.01). Moreover, bLac in a group of dead or culled dams and in that of survived dams were 10.2 and 3.1 mmol/l, respectively (P<0.01). Furthermore, the proposed diagnostic cutoffs for bLac based on ROC analysis for detection of uterine necrosis and poor prognosis in dams were set at >5.0 and >6.5 mmol/l, respectively. These findings suggest that in dairy cows with uterine torsion, an increase in bLac is a diagnostic predictor of uterine necrosis as well as poor prognosis in dams.

Zusammenfassung Gegenstand: Untersuchung des Einflusses konservativ nicht therapierbarer Torsio uteri intra partum mit Sectio caesarea auf den Blutplasmagehalt des C-reaktiven Proteins (CRP) im Vergleich mit Dystokien anderer Genese und Sectio caesarea sowie Normalgeburten beim Rind. Material und Methode: In die Studie gingen 55 Rinder ein, eingeteilt in drei Gruppen. Gruppe 1 bestand aus 31 Rindern mit operativ beendeter Torsio uteri intra partum. In Gruppe 2 befanden sich 13 Tiere mit durch Kaiserschnitt beendeter Dystokie anderer Genese und in Gruppe 3 11 Kühe mit Normalgeburten und ungestörtem Puerperium. Im Abstand von 24 Stunden, beginnend unmittelbar präoperativ, bis 10 Tage post operationem wurden Blutproben aus der V. jugularis externa entnommen und das CRP im Plasma mittels ELISA quantitativ bestimmt. Ergebnisse: Schwere intrazelluläre Ödeme und Nekrosen am Uterus als Folge einer Torsio uteri intra partum führten zu einem Anstieg der CRPKonzentration, eine Ovariohysterektomie bedingte einen Abfall des CRP-Spiegels. Der alleinige chirurgische Eingriff einer Sectio caesarea verursachte keine wesentliche akute Veränderung der CRP-Konzentration. Aufgrund der großen individuellen Variation der CRP-Konzentrationen war eine Definition eindeutiger Grenzwerte bei den einzelnen Tiergruppen nicht möglich. Eine prognostische Aussage zur Fertilität nach Torsio uteri und Kaiserschnitt lässt sich anhand des CRP-Werts nicht ableiten. Der positive Einfluss der Milchleistung auf die CRP-Konzentration im Blutplasma konnte bestätigt werden. Schlussfolgerung: Nekrosen und schwere intrazelluläre Ödeme am Uterus beeinflussen die CRP-Blutplasmakonzentration deutlich. Klinische Relevanz: Hohe CRP-Werte (> 90 μg/ml) sprechen bei Rindern mit Torsio uteri intra partum für eine schwere Uterusschädigung, die mit einer drastischen Verschlechterung der Prognose quo ad vitam einhergeht. Eine Ovariohysterektomie kann in diesen Fällen eine gute Therapieoption sein.
