Abstract: | Purpose: To provide follow-up data on endovascular intervention for venous stenoses in the pelvis.
Methods: Between 1985 and 1995, 35 patients presented with 42 stenoses of the pelvic veins after operative thrombectomy and creation
of an arteriovenous fistula, combined with intraoperative venous angioscopy. All patients underwent angioplasty and, if unsuccessful,
percutaneous insertion of an endovascular stent (n = 7).
Results: Angioplasty with and without endovascular stenting was technically successful in 34 of 35 patients (97%). Average length
of the stenoses was 20.6 mm (range 10–90 mm), average diameter before dilation 4.1 mm (range 2–6 mm), and average diameter
after dilation 10.1 mm (range 5–18 mm). Intraoperative angioscopy showed pathologic findings (intimal laceration or residual
thrombotic material) in 14 patients. After an average follow-up period of 4.13 years, 24 (69%) patients had patent veins.
The difference in the primary patency rate between patients with angioscopically abnormal veins (6 of 14 patients, corresponding
to a patency rate of 43%) and patients with angioscopically normal veins after thrombectomy (18 of 21 patients, corresponding
to a patency rate of 86%) was statistically significant (p < 0.01, log rank test).
Conclusions: Percutaneous transluminal angioplasty and/or stenting are good treatment modalities for pelvic vein stenosis following surgical
thrombectomy. Angioscopically abnormal veins have a poorer long-term patency, regardless of the type of intervention. |
