Abnormal uterine bleeding in a 2-month-old infant: Workup, instrumentation, and endoscopic management-A case report

A case report of a 2‐month‐old patient with severe abnormal uterine bleeding and vascular neoplastic malformation who was diagnosed and managed by endoscopic and vessel embolization therapy.

The use of the double uterine segment tourniquet in obstetric hysterectomy for bleeding control in patients with placenta accreta spectrum

OBJECTIVES

To evaluate surgical outcomes of using a double uterine segment tourniquet in obstetric hysterectomy for bleeding control in patients with placenta accreta spectrum.

METHODS

Retrospective case-control study conducted at the Central Hospital of San Luis Potosi, Mexico. Patients with the diagnosis of placenta accreta spectrum who underwent obstetric hysterectomy were included. Two groups were formed: in the first, a double uterine segment tourniquet was used; and in the second, the hysterectomy was performed without a tourniquet. Primary surgical outcomes were compared.

RESULTS

Forty patients in each group were included. The use of a double uterine segment tourniquet had lower total blood loss compared with the non-tourniquet group (1054.00 ± 467.02 vs. 1528.75 ± 347.12 mL, P = 0.0171) and a lower drop in hemoglobin (1.74 ± 1.10 vs. 2.60 ± 1.25 mg/dL, P = 0.0486). Ten patients (23.80%) in the double tourniquet group required blood transfusion, compared with 26 (65.00%) in the non-tourniquet group (P = 0.0003). Surgical time did not show a statistical difference between groups.

CONCLUSION

The use of a uterine segment tourniquet in obstetric hysterectomy may improve surgical outcomes in patients with placenta accreta spectrum with no difference in surgical time and urinary tract lesions.

Magnetic resonance imaging (MRI) spinal cord and canal measurements in normal dogs

The goal of this study was to establish Magnetic resonance imaging (MRI) reference ranges for spinal measurements in normal dogs. Forty dogs (1–10 kg, 11–20 kg, 21–30 kg, > 30 kg; 10 dogs per category) underwent spinal MRI. Measurements were performed on sagittal T2-W images at the level of the 4th thoracic vertebra (T4), the 9th thoracic vertebra (T9) and the 3rd lumbar vertebra (L3). Spinal canal diameter (mm) ranged from 6.07 ± 0.63 (1–10 kg) to 8.27 ± 1.15 (> 30 kg) at the level of T4; 6.55 ± 0.61 (1–10 kg) to 9.04 ± 1.26 (> 30 kg) at the level of T9; and 6.80 (6.47–7.00; 1–10 kg) to 9.00 (7.90–9.73; > 30 kg) at the level of L3. There were significant differences (P < 0.05) in spinal canal diameter between groups. Mean spinal cord diameter (mm) ranged from 4.46 ± 0.51 (11–20 kg) to 4.70 ± 0.35 (1–10 kg) at the level of T4; 4.41 ± 0.50 (> 30 kg) to 4.85 ± 0.57 (1–10 kg) at the level of T9; and 4.52 ± 0.51 (> 30 kg) to 5.14 ± 0.68 (1–10 kg) at the level of L3. There were no significant differences in spinal cord diameter between groups. Spinal cord-to-spinal canal ratio varied significantly, ranging from 0.51 ± 0.08 (> 30 kg at L3) to 0.78 (0.69–0.80; 1–10 kg at T4) (P < 0.05). These findings are important when using MRI to evaluate patients with suspected diffuse spinal cord disease.
