Total hip replacement surgery can temporarily lower blood pressure in the legs. This blood pressure decrease is reversible and not dangerous for patients without signs of ischemia.

Area of Science:

  • Vascular Surgery
  • Orthopedic Surgery
  • Hemodynamics

Background:

  • Total hip replacement (THR) is a common orthopedic procedure.
  • Postoperative hemodynamic changes, particularly in limb blood pressure, require investigation.

Purpose of the Study:

  • To assess changes in systemic and segmental blood pressure following total hip replacement.
  • To evaluate the reversibility and clinical significance of these pressure changes.

Main Methods:

  • Systemic systolic and segmental blood pressures (ankle and toe) were measured in 29 patients before and 1, 6 weeks after THR.
  • Patients without signs of ischemia were included.
  • Ankle-toe gradient pressure was analyzed in a subgroup with preoperative low ankle pressure.

Main Results:

  • A significant transient drop in all measured pressures was observed 1 week postoperatively.
  • The decrease mirrored systemic pressure changes and normalized by 6 weeks.
  • A transient further decrease in ankle-toe gradient pressure occurred on the operated side in a subgroup, without symptoms.

Conclusions:

  • Postoperative segmental blood pressure decrease after THR is a reversible phenomenon.
  • In patients without signs of ischemia, this transient pressure drop is not considered dangerous.
