Summary
This summary is machine-generated.

Flowmeters assess microvascular surgery anastomoses, aiding free tissue transfer outcomes. While subjective methods prevail, quantitative flowmetry may predict complications and guide revisions for improved patient results.

Area of Science:

  • Plastic Surgery
  • Vascular Surgery
  • Surgical Technology

Background:

  • Flowmeters are standard for coronary anastomosis patency assessment.
  • Limited evidence exists for flowmetry in plastic surgery microvascular anastomoses.
  • Current practice relies on subjective patency tests for immediate flow assessment.

Purpose of the Study:

  • To review flowmeter devices in microvascular surgery.
  • To assess their role in improving free tissue transfer outcomes.
  • To identify objective predictors for microvascular anastomosis adequacy.

Main Methods:

  • Systematic literature search using MEDLINE, EMBASE, and Cochrane databases.
  • Keywords included "flowmeter," "Doppler ultrasound," "transit volume flow," "laser Doppler flowmeter," and "microsurgery."
  • Included experimental and clinical studies assessing microvascular anastomoses with flowmeters.

Main Results:

  • 718 publications and 14 full-text articles were reviewed.
  • Flowmeters are currently used for qualitative assessment of microvascular anastomoses.
  • Potential exists for quantitative flowmetry to predict outcomes and guide revisions.

Conclusions:

  • Flowmetry shows promise in postoperative free flap monitoring and complication prevention.
  • Quantitative flow measurements could intraoperatively predict outcomes and the need for revision.
  • Further research is needed to establish objective flowmetry predictors in microvascular surgery.
