Ultrasound-guided suction using negative pressure, curettage, and percutaneous drainage to treat rectus sheath hematoma.

BACKGROUND

This study aimed to introduce and evaluate a new treatment method for rectus sheath hematoma: ultrasound-guided suction using negative pressure, curettage, and percutaneous drainage.

METHODS

This retrospective study involved five patients with rectus sheath hematoma rectus sheath hematoma who had cesarean sections. For all patients, ultrasound revealed that the maximum diameter of their hematoma exceeded 70 mm. We summarized and analyzed the therapeutic effects of five patients and introduced the procedure, technical points, precautions, advantages, and indications of the procedure.

RESULTS

In all five patients, hematoma area was significantly reduced as confirmed by ultrasound at follow-up, and all patients' abdominal pain were significantly relieved. No complications, including bleeding or infection, were detected at both the 2-h postoperative and 3-day follow-up assessments. The hematoma volume reduction rates were 90 %, 67 %, 81 %, 68 %, and 70 % at three days re-examinations, and 99 %, 96 %, 98 %, 98 %, and 90 % at the 30-day follow-up.

CONCLUSION

The removal of rectus sheath hematoma by suction using negative pressure can prevent patients from undergoing abdominal wall exploration, offering a less invasive alternative while potentially achieving comparable therapeutic effect to surgical hematoma removal in certain cases. This treatment method shows potential for clinical application, particularly in relatively young and healthy postpartum women, and is expected to be popularized and applied in clinical practice.
