title: Mid term results of ultrasound guided foam sclerotherapy for complicated and uncomplicated varicose veins.
abstract: OBJECTIVE
  The aim was to describe the results of starting a foam sclerotherapy service, focussing on patients with complicated venous disease.
  
  
  METHODS
  Consecutive patients undergoing ultrasound-guided foam sclerotherapy for truncal varicose veins underwent clinical and hand-held Doppler assessment at 2 weeks and venous duplex imaging at 6 months.
  
  
  RESULTS
  One hundred and eighty-five truncal veins were treated in 165 patients. A high proportion of veins were complicated (109 CEAP classes 4-6, 76 CEAP 1-3). Ninety-one percent (168) had a single treatment session. After 2 weeks, ninety-three percent (136/147) of the truncal veins appeared occluded on hand-held Doppler examination. Ten percent (15/147) of patients had remaining visible varicosities in the lower leg. After six months, the truncal vein remained occluded in 74% (68/92), was partially occluded in 10% (9/92) and fully patent in 16% (15/92). There was no significant difference in occlusion rates between: primary (45/60-75%) and recurrent (23/32-72%) veins; CEAP 2-3 (22/30-73%) and CEAP 4-6 (46/62-74%) veins; veins with diameter <7 mm (29/38-76%) or > or =7 mm (13/23-57%). No patient had evidence of deep vein thrombosis, though nine (10%) had new segmental deep venous reflux compared with pre-treatment scans.
  
  
  CONCLUSIONS
  Foam sclerotherapy was equally effective for complicated and uncomplicated varicose veins.
