Outcomes
Three SVs occluded post surgery (1 TA, 1 PC and 1 IC) at 36 months, 4
months and 1 day post decompression. Of these, 2 (TA and PC) underwent
venoplasty which was successful in the first patient but in the second
the venous occlusion was unable to be crossed with a wire. This was
treated conservatively as was the patient occluding after one day post
IC decompression. All three remained asymptomatic. Hence the secondary
patency rates of SV were 23/26 (88%) with all (100%) asymptomatic.
