Progression of chronic venous disease (CVD) is common, with nearly one-third of patients experiencing worsening symptoms or venous reflux. Delaying elective vein surgery may require repeat duplex ultrasound (DU) exams if more than six months have passed.

Area of Science:

  • Vascular Surgery
  • Medical Diagnostics
  • Patient Outcomes

Background:

  • Chronic venous disease (CVD) progression is not well understood.
  • Patients often question delaying elective vein surgery.
  • This study investigates the natural history of CVD.

Purpose of the Study:

  • To determine the progression of chronic venous disease (CVD) in patients who delayed elective vein surgery.
  • To assess changes in clinical stage and duplex ultrasound (DU) findings over time.
  • To inform clinical decision-making regarding treatment timing.

Main Methods:

  • Retrospective study of 116 limbs in 90 patients with CVD.
  • Patients underwent at least two duplex ultrasound (DU) scans before surgery.
  • Classification of disease severity using the CEAP system.

Main Results:

  • Nearly one-third of patients (31 limbs) showed disease progression on repeat DU scans.
  • Progression included extension of existing reflux or new reflux in different segments.
  • Symptomatic or DU changes were noted at 6 months or later in most limbs, with progression diagnosed at 12 months or later in 74.2% of cases.

Conclusions:

  • Progression of chronic venous disease (CVD) is frequent, affecting nearly one-third of patients with venous reflux.
  • Anatomic changes and extension of reflux are common with disease progression.
  • Repeat duplex ultrasound (DU) examinations may be necessary for patients whose treatment is delayed by more than six months.
