[Long-term MRI follow-up of aortic dissection in 56 patients: therapeutic impact].
PURPOSE: To retrospectively assess the value of MRI in long-term follow-up of aortic dissection (AD) and its impact on therapy. MATERIALS AND METHODS: Comparison of clinical progression and analysis of 215 MRI examinations performed on 56 patients in our center from 1991 to 2002. RESULTS: Twenty-six patients (46%) had AD complications: 14 (54%) were asymptomatic and eight (31%) had subsequent surgical repair (native aorta upstream prosthesis disease in three patients and aneurismal dilatation of false lumen in five cases). Of the eight patients with secondary surgery, five (63%) were clinically asymptomatic. The delay between initial dissection and secondary surgery was less than 5 years in five patients and exceeded 10 years in three cases. The remaining 30 patients (54%) had unmodified radiological findings after a mean follow-up of 3.5 years (6 months to 9 years). CONCLUSION: MRI depicted AD complications in long-term follow-up of sometimes asymptomatic patients, allowing for adaptation of surgical treatment in 26 cases (46%).
Portal vein stenosis and occlusion stenting after liver transplantation in two adults.
We report two cases of percutaneous transhepatic stenting of the portal vein to treat stenosis and occlusion disclosed 5 and 18 months, respectively, after orthotopic liver transplantation in two adult patients. If long-term patency is satisfactory, this technique should allow long-term management of portal vein stenosis and occlusion without the use of thrombolysis.
[Femoral superficial artery angioplasty: long term results, initial predictive factors. 101 patients].
OBJECTIVE: To evaluate immediate results, clinical improvement, long-term patency and predictive factors of long-term outcome after superficial femoral artery percutaneous angioplasty. PATIENTS AND METHODS: Restrospective monocentric study of 101 patients (142 lesions: 105 stenoses and 37 occlusions) technical results, long-term patency (19 months), and clinical improvement (27,5 months) were analyzed. A multifactorial analysis was performed. RESULTS: Technical success was obtained in 99%, complications and mortality rates were respectively 3% and 2%. At the end of follow-up, 55 patients were clinically improved (20 lost to follow-up), and femoral artery remained patent in 62 patients (10 to follow-up). Statistical analyses revealed 8 significant predictive factors of a good outcome (P<0.05): female gender, non-diabetic, at least one patent artery below the knee, AHA classification <2, no stent, treatment of an occlusion, number of dilatations<3, treatment by statins for hypercholesterolemia. CONCLUSION: Femoral superficial artery angioplasty is usually achieved with low complication rate. We found eight factors predictive of long-term outcome, to keep in mind when indications are discussed.
