The influence of gender on patency rates after iliac artery stenting

ObjectiveThe purpose of this study was to investigate the influence of gender on the long-term outcome after iliac artery stenting and to assess gender-specific differences of the influence of risk factors on treatment success and patency rates.MethodsBetween January 2000 and December 2006, 404 percutaneous transluminal angioplasties with primary stent deployment for symptomatic iliac artery occlusive disease were performed at our center. These included 128 interventions in women and 276 interventions in men.ResultsWhereas average age was significantly higher (65.9 ± 12.9 years; P = .007) and arterial hypertension more frequent (60.9% vs 49.3%; P = .032) in women, hyperuricemia (7.0% vs 14.1%; P = .047) and a positive smoking status (61.7% vs 74.3%; P = .014) were more frequently observed in men. Fontaine stage was more advanced (stages III and IV) in women than in men (P = .028; P < .001). Technical success was 97.7% in women and 99.3% in men. Overall complication rate was higher in women compared with men (P = .002), mostly caused by access site hematomas (4.7% vs 0.4%) and pseudoaneurysms (8.6% vs 2.5%). Patients were followed up for 45.0 ± 33.3 months. Restenosis developed in 16.8% of cases in women and in 14.6% of cases in men and was treated in 73.7% by an endovascular approach. Primary patency rates at 1, 3, 5, and 7 years were 90.3%, 77.2%, 60.2%, and 46.4% in women and 89.9%, 71.5%, 63.6%, and 59.7% in men, respectively (P = .524; log-rank, .406). Secondary patency rates were 97.2%, 91%, 81.5%, and 70.3% in women and 97.1%, 89.1%, 82.6%, and 78% in men, respectively (P = .959; log-rank, .003). Multivariate analysis identified lower age as the only independent risk factor for recurrent disease in both groups. Age-defined subgroup analysis showed a restenosis/reocclusion rate of 23.9% in men and 22.1% in women older than 63.5 years (P = .861) but 32.1% in men and 49.1% in women younger than that (P = .034).ConclusionsOur data suggest that although women are older and present with a more advanced stage of peripheral arterial occlusive disease, endovascular therapy is equally effective irrespective of gender. Surprisingly, the subgroup of young female patients had a specifically poor outcome

Impact of a compression garment, on top of the usual care, in patients with breast cancer with early disturbance of the lymphatic transport: protocol of a randomised controlled trial.

INTRODUCTION: Breast cancer-related lymphoedema (BCRL) is a common phenomenon. When lymphoedema is diagnosed late, options for treatment are diminished. Therefore, early diagnosis and treatment are very important to alter the potential deleterious evolution. Lymphofluoroscopy visualises the superficial lymphatic architecture in detail, giving the opportunity to detect a disturbance in the lymphatic transport (ie, dermal backflow) before the lymphoedema is clinically visible.The main objective is to investigate if there is an additional effect of a compression garment on top of the usual care (ie, information and exercises) in patients with early disturbance of the lymphatic transport after breast cancer treatment. Development of clinical lymphoedema and/or deterioration of the dermal backflow visualised by lymphofluoroscopy is investigated. METHODOLOGY: All patients scheduled for breast cancer surgery with unilateral axillary lymph node dissection or sentinel node biopsy in the Multidisciplinary Breast Clinic of the University Hospitals Leuven are being considered. Patients are assessed before surgery and at 1, 3, 6, 9, 12, 18, 24 and 36 months postoperatively. At each visit, a clinical assessment is performed determining the volume difference between both arms and hands (through circumference measurements and water displacement), the water content, the extracellular fluid, the pitting status and the skinfold thickness. Quality of life questionnaires are filled in. At each visit, a lymphofluoroscopy is performed as well. When a disturbance of the lymphatic transport is seen on lymphofluoroscopy, without the presence of clinical lymphoedema, the patient is randomised in either a control group receiving usual care or a preventive treatment group receiving usual care and a compression garment (whether or not combined with a glove). ETHICS AND DISSEMINATION: The trial is conducted in compliance with the principles of the Declaration of Helsinki (2008), the principles of Good Clinical Practice and in accordance with all applicable regulatory requirements. This protocol has been approved by the Ethical Committee of the University Hospitals Leuven. Results will be disseminated by peer-reviewed scientific journals and presentation at international congresses. TRIAL REGISTRATION NUMBER: NCT03210311 CONCLUSION: The investigators hypothesise that development of clinical BCRL can be prevented and/or the dermal backflow can be stabilised or improved, if a preventive treatment with compression garment is started in the early phase of disturbance.status: Published onlin

Covered versus bare metal kissing stents for reconstruction of the aortic bifurcation in the ILIACS registry

Objective: We compared the early and mid-term outcomes of polytetrafluoroethylene covered stents (CSs) vs bare metal stents (BMSs) used in the kissing conformation for the reconstruction of the aortic bifurcation in aortoiliac obstructive disease. Methods: A multicenter cohort registry (2015-2019) collected data from 1306 patients who had undergone endovascular treatment of aortoiliac arterial obstructive disease. Only patients who had received bilateral iliac kissing stents for TransAtlantic Inter-Society Consensus (TASC) class C and D lesions were included in the present analysis. The 30-day outcomes, mid-term primary patency, and limb salvage rates were compared between the CSs and BMSs in matched patient cohorts after propensity score matching. The follow-up results were analyzed using Kaplan-Meier curves. Cox proportional hazards models were used to identify the predictors of primary patency. Results: A total of 336 patients were treated with kissing stents, 201 with CSs (60%) and 135 with BMSs (40%). In the unmatched cohort, patients receiving CSs were more likely to have critical limb ischemia (41% vs 30%; P = .038), complex iliac lesions, such as TASC D (90% vs 56%; P < .01), and iliac occlusions (59% vs 44%; P < .01). After propensity score matching, 220 patients were selected (110 with CSs and 110 with BMSs), without differences in the clinical presentation (critical limb ischemia, 41% vs 33%; P = .167), or anatomic complexity (TASC D, 66% vs 60%, P = .21; iliac occlusion, 48% vs 49%, P = .89). The 30-day mortality was 0%. The early medical (unmatched, 5% vs 4%, P = 1.00; matched, 5% vs 4%, P = .75) and surgical (unmatched, 5% vs 5%, P = 1.00; matched, 5% vs 3%, P = .72) complication rates were similar between the CSs and BMSs. However, the CSs resulted in a lower risk of intraoperative iliac rupture (0% vs 3.5%; P = .013) and greater ankle-brachial index improvement (0.43 ± 0.22 vs 0.36 ± 0.24; P = .02). At 36 months, the overall primary patency (92% ± 7% vs 92% ± 8%; P = .38), secondary patency (98% ± 3% vs 98% ± 4%; P = .50), and limb salvage (93% ± 9% vs 97% ± 5%; P = .20) rates were similar. In cases of moderate to severe iliac calcification, the CSs showed better results in the matched cohort (100% vs 89% ± 9%; P = .048). On multivariate analysis, CS use (hazard ratio [HR], 1.67; P = .45) did not significantly affect primary patency, but older age (HR, 0.93; P = .03) and kissing stent diameter ≥8 mm (HR, 0.25; P = .03) were significantly associated. Conclusion: In the present multicenter study, the use of kissing stents for the treatment of the aortic bifurcation provided good early and mid-term results. CSs were preferred for more complex lesions, were protective from iliac rupture, and allowed for greater ankle-brachial index improvement. The 3-year patency rates were similar between the CSs and BMSs. However, CSs showed improved results in the case of moderate to severe calcification
