Feasibility and safety of endovascular treatment for chronic cerebrospinal venous insufficiency in patients with multiple sclerosis.

OBJECTIVE: Chronic cerebrospinal venous insufficiency (CCSVI) is a recently discovered syndrome mainly due to stenoses of internal jugular (IJV) and/or azygos (AZ) veins. The present study retrospectively evaluates the feasibility and safety of endovascular treatment for CCSVI in a cohort of patients with multiple sclerosis (MS). METHODS: From September 2010 to October 2012, 1202 consecutive patients were admitted to undergo phlebograpy ± endovascular treatment for CCSVI. All the patients had previously been found positive at color Doppler sonography (CDS) for at least two Zamboni criteria for CCSVI and had a neurologist-confirmed diagnosis of MS. Only symptomatic MS were considered for treatment. Percutaneous transluminal angioplasty was carried out as an outpatient procedure at two different institutes. Primary procedures, regarded as the first balloon angioplasty ever performed for CCSVI, and secondary (reintervention) procedures, regarded as interventions performed after venous disease recurrence, were carried out in 86.5% (1037 of 1199) and 13.5% (162 of 1199) of patients, respectively. Procedural success and complications within 30 days were recorded. RESULTS: Phlebography followed by endovascular recanalization was carried out in 1999 patients consisting of 1219 interventions. Balloon angioplasty alone was performed in 1205 out of 1219 (98.9%) procedures, whereas additional stent placement was required in the remaining 14 procedures (1.1%) following unsuccessful attempts at AZ dilatation. No stents were ever implanted in the IJV. The feasibility rate was as high as 99.2% (1209 interventions). Major complications included one (0.1%) AZ rupture occurring during balloon dilatation and requiring blood transfusion, one (0.1%) severe bleeding in the groin requiring open surgery, two (0.2%) surgical openings of the common femoral vein to remove balloon fragments, and three (0.2%) left IJV thromboses. The overall major and minor complication rates at 30 days were 0.6% and 2.5%, respectively. CONCLUSIONS: Endovascular treatment for CCSVI appears feasible and safe. However, a proper learning curve can dramatically lower the rate of adverse events. In our experience, the vast majority of complications occurred in the first 400 cases performed.

Bronchial artery embolization for the management of nonmassive hemoptysis in cystic fibrosis.

STUDY OBJECTIVES: Hemoptysis is a common complication in patients with cystic fibrosis (CF). Current approaches to patients with hemoptysis include conservative medical therapy, bronchial artery embolization (BAE), and surgery. We investigated the effectiveness of early BAE on the outcome in patients with minor bleeding. DESIGN, PATIENTS, AND INTERVENTIONS: We reviewed the clinical records from the Cystic Fibrosis Service for eight consecutive patients treated with medical therapy who had undergone early BAE and eight matched patients treated with conservative medical therapy alone. MEASUREMENTS: We assessed the mean number of bleeding episodes, pulmonary exacerbations, lung function (FEV(1)), Shwachman score, and Nottingham Health Profile (NHP) scores, the year before BAE and for the 3 ensuing years. RESULTS: During a 3-year follow-up, patients who underwent embolization had significantly fewer bleeding episodes (p < 0.001) and pulmonary exacerbations (p < 0.006). Lung function declined significantly in both groups (p < 0.001). The modified Shwachman score declined significantly during the follow-up only in patients who did not undergo embolization (p < 0.001). Patients treated by early embolization had significantly better NHP scores, indicating a better quality of life (p < 0.05). None of the patients who underwent BAE had adverse reactions. CONCLUSIONS: Early BAE in patients with CF who have nonmassive hemoptysis is an effective, safe therapeutic approach offering better long-term control of recurrent bleeding and quality of life than medical therapy alone.
