Varicose Veins II: Diagnostic Studies and Interprofessional Care01:26

Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Area of Science:

  • Thoracic Surgery
  • Pulmonary Medicine
  • Surgical Innovation

Background:

  • Sublobar resection is effective for small lung nodules, but precise anatomical segmentectomy is challenging.
  • Accurate identification of intersegmental planes is crucial for successful segmentectomy.
  • Existing methods for identifying intersegmental planes require improvement in precision and efficiency.

Purpose of the Study:

  • To introduce and evaluate the novel Artery-priority, Inflation/deflation, Vein/Bronchus (AIDVB) procedure for anatomical segmentectomy.
  • To assess the AIDVB procedure's effectiveness in improving intersegmental plane identification and surgical outcomes.
  • To compare the AIDVB procedure with traditional anatomical segmentectomy in terms of surgical parameters and postoperative recovery.

Main Methods:

  • A comparative study involving 1485 patients undergoing anatomical segmentectomy between January 2019 and December 2021.
  • 1,342 patients underwent traditional segmentectomy, while 143 patients received the AIDVB procedure.
  • Preoperative 3D-CT bronchovascular anatomy (3D-CTBA) was used for planning; operative times, inflation pressures, and postoperative inflammatory markers (IL-6, SP-D) were compared.

Main Results:

  • The AIDVB procedure demonstrated superior intersegmental plane identification, particularly through an artery-priority approach.
  • AIDVB group showed significantly shorter operative times (87.38 vs 101.09 min, P=.001) and lower inflation pressures (22.8 vs 37.8 cmH2O, P=.001).
  • AIDVB resulted in reduced postoperative inflammatory markers (IL-6, SP-D), shorter drainage duration, and faster hospital discharge, indicating improved recovery.

Conclusions:

  • The AIDVB procedure offers enhanced precision in intersegmental plane identification for anatomical segmentectomy.
  • Advantages include shorter operative times, reduced inflation pressure, minimized alveolar injury, and faster postoperative recovery.
  • The systematic nature and minimal equipment needs of AIDVB support its widespread clinical adoption.
