Transrectal Doppler Characterization of Uterine Vascular Dynamics In Buffaloes With Clinical Metritis and Subsequent Recovery

The study was conducted at the Referral Veterinary Polyclinic (VGO-OPD), ICAR–Indian Veterinary Research Institute (IVRI), Izatnagar, Uttar Pradesh, India during 2023–2024 to determine whether Doppler-based uterine hemodynamic indices can objectively differentiate the vascular alterations associated with clinical metritis in early-postpartum buffaloes and to evaluate their normalization following therapeutic recovery. The study characterized uterine vascular dynamics in pluriparous buffaloes diagnosed with clinical metritis within 21 days postpartum using transrectal color and spectral Doppler ultrasonography. Ten affected animals were evaluated, and Doppler indices of the middle uterine artery viz. resistance index (RI), pulsatility index (PI), time-averaged maximum velocity (TMAX), arterial diameter, and blood flow volume (BFV) were recorded before and after therapeutic intervention consisting of ceftiofur, flunixin meglumine, uterine lavage, and supportive therapy. During the disease phase, RI and PI were significantly reduced (p
