Outcome of invasive procedures for venous thrombosis in Behcet's syndrome: case series and systematic literature review.

OBJECTIVES: Systemic therapy aimed at suppressing the diffuse inflammation in the vessel wall is the major treatment modality for venous thrombosis in Behcet's syndrome (BS). Endovascular and/or surgical interventions are also used. We here report five patients who were referred to our clinic after having such interventions and also present a literature review to assess the outcome of invasive procedures for venous thrombosis in BS. METHODS: Our patients were presented and a literature search for endovascular and/or surgical interventions in Pub-Med was performed. Recanalisation, reocclusion or other complications were assessed as outcomes. RESULTS: Five BS patients with lower extremity thrombosis were referred to our clinic with post thrombotic syndrome due to incomplete recanalisation or infectious complication after endovascular interventions. Twenty-one articles reporting on 36 patients were found suitable for review. There were totally 21 lower extremity venous intervention cases, 14 of which had failure such as complication, reocclusion or incomplete recanalisation. Reocclusions occurred in 10 patients and reinterventions to 8 of them could restore flow only in 4 cases. Ileal infarct and vena cava wall-duodenal perforation were major complications. Invasive procedures of 8 abdominal thrombosis cases resulted with death due to ileus in one patient, and reocclusion in another. Seven of the 12 upper extremity/superior vena cava thrombosis cases resulted with reocclusions. CONCLUSIONS: Endovascular and surgical interventions seemed to be unsuccessful because of recurrent infectious and vascular complications in 22 (53.6%) of 41 patients with venous thrombosis. The indication of these procedures is controversial. Their economic burden on the healthcare system must be considered.
