Cardiovascular Risk Assessment in Women With Rheumatoid Arthritis Through Carotid and Femoral Artery Doppler Ultrasound.

OBJECTIVE: The aims of this study were to assess cardiovascular risk in patients with rheumatoid arthritis (RA) classified as low-risk by the Framingham score, before and after the multiplication by 1.5 recommended by the European League Against Rheumatism (EULAR), and to stratify them using carotid and femoral Doppler ultrasound (DUS) in order to optimize the assessment of the asymptomatic cardiovascular disease incidence. METHODS: Thirty-five female patients with RA and 35 healthy women (control group), both with low cardiovascular risk by Framingham score, were enrolled in the study (randomized). All of them underwent carotid and femoral DUS studies. RESULTS: The mean age at diagnosis was 44.57 years, the mean disease duration was 12.11 years and the mean disease activity score according to the Disease Activity Score 28 was 1.91, whereas according to the Clinical Disease Activity Index, it was 6.176. The sample was homogeneous. Within the RA group, 46% showed changes in the carotid and/or femoral DUS, compared with 14% in the control group (p = 0.004). Of the DUS with abnormalities, in the RA group, 31% of the carotid DUS and 81% of the femoral DUS (p = 0.005) showed intima-media thickness and/or atherosclerotic plaques. After EULAR 1.5 multiplication factor, 66% remained low cardiovascular risk. Of these, 35% of the patients showed changes in the carotid and/or femoral DUS, compared with 14% of the control group (p = 0.07). CONCLUSIONS: The EULAR criteria are effective at identifying patients with high cardiovascular risk. Carotid DUS and, especially, femoral DUS are tools that can be used in clinical practice as ways to detect CVD even in its asymptomatic form.

Ultrasound Aspects and Recanalization Rates in Patients with Lower-Limb Deep Venous Thrombosis Treated with Rivaroxaban.

BACKGROUND: In this article, we report the ultrasound aspects and recanalization rates of patients with deep venous thrombosis (DVT) in the lower limbs treated with the rivaroxaban, focusing on the recanalization rate and the ultrasonographic aspects. METHODS: This was a prospective and consecutive cohort study of patients admitted with DVT who were submitted to treatment with rivaroxaban for 6 months at the Division of Vascular and Endovascular Surgery, Hospital do Servidor Público Estadual, São Paulo, Brazil, between March 2016 and July 2018. RESULTS: Fifty-one patients with DVT were admitted to the Vascular Surgery Department and received rivaroxaban for 6 months. The follow-up time was 360 days. Analyses were performed at 180 and 360 days. The rate of total venous recanalization at 360 days was 76.4% (39 patients). The incidence of partial venous recanalization was 23.5% (12 patients). At the first month, 11 patients (21.7%) continued with total occlusion of the vein, with 4 patients (6.5%) with no residual thrombi. However, at 6 months, only 2 patients (2.2%) continued with total occlusion of the vein, with 26 patients (47.8%) with no residual thrombi. At 12 months, there were 39 patients (76.4%) with no residual thrombi. Univariate and multivariate logistic regression identified the following factors related to total venous recanalization: the absence of popliteal vein reflux (odds ratio [OR], 0.386; P = 0.007), no residual thrombi (OR, 3.213; P = 0.008), femoropopliteal clot length at 1 month (OR, 3.021; P = 0.016), femoropopliteal clot length at 6 months (OR, 2.234; P = 0.008). The incidence of post-thrombotic syndrome (PTS) at 12 months was 8.3%. CONCLUSIONS: In this study, patients who received oral rivaroxaban displayed satisfactory total vein recanalization rate after 6 months and 12 months. The factors associated with better total recanalization rates were the absence of popliteal vein reflux, the absence of residual thrombi in the veins, femoropopliteal clot length at 1 month (OR, 3.021; P = 0.016), and femoropopliteal clot length at 6 months (OR, 2.234; P = 0.008). Moreover, the incidence of PTS at 12 months was 8.3%.

Comparison of the recanalization rate and postthrombotic syndrome in patients with deep venous thrombosis treated with rivaroxaban or warfarin.

BACKGROUND: In this article, we report the outcomes of patients with deep venous thrombosis in the lower limbs treated with the oral anticoagulant rivaroxaban or warfarin, focusing on the recanalization rate (measured with duplex ultrasound) and the incidence of postthrombotic syndrome. METHODS: This was a prospective, consecutive, randomized, blind cohort study of patients admitted with deep venous thrombosis to the Division of Vascular and Endovascular Surgery, Hospital do Servidor Público Estadual, São Paulo, Brazil, between March 2016 and July 2018. The patients were randomized into 2 groups and treated with oral anticoagulation for 6 months: either rivaroxaban (group 1) or warfarin (group 2). The study was registered at clinicaltrials.gov under NCT 02704598. RESULTS: Eighty-eight patients with deep venous thrombosis were admitted to the Vascular Surgery Department and randomized into the 2 groups. The follow-up time was 360 days. Analyses were performed at 180 and 360 days. Four patients were excluded from the study during follow-up because of a diagnosis of ovarian cancer (1 patient), head and neck cancer (1 patient), lung cancer (1 patient), and stomach cancer (1 patient). Therefore, 84 patients were evaluated: 46 patients in group 1 and 38 in group 2. The incidence of postthrombotic syndrome was 17.9% (15 cases) in the total cohort, but was significantly higher in group 2 (11 cases, 28.9%) than in group 1 (4 cases, 8.7%; P < .001; odds ratio, 4.278). The rate of total venous recanalization at 360 days was 40.5% (34 patients) in the total cohort, but was significantly higher in group 1 (35 patients, 76.1%) than in group 2 (5 patients, 13.2%; P < .001). The incidence of partial venous recanalization was 46.4% and was significantly higher in group 2 (28 patients, 73.7%) than in group 1 (11 patients, 23.9%; P = .016). Five patients in the total cohort (6%) showed no venous recanalization, all of them in group 2 (P = .016). CONCLUSION: In this study, patients who received oral rivaroxaban displayed a lower incidence of postthrombotic syndrome and a better total vein recanalization rate after 6 and 12 months than patients who received warfarin.

Impact of calcification and infrapopliteal outflow on the outcome of endovascular treatment of femoropopliteal occlusive disease.

OBJECTIVES: In this paper, we report the long-term outcomes of the endovascular treatment of femoropopliteal occlusive disease, focusing on the importance of calcification and runoff outflow on limb salvage and patency, and the factors associated with these outcomes at a single center. METHODS: This retrospective cohort study included consecutive patients with femoropopliteal occlusive who underwent femoropopliteal angioplasty at the Division of Vascular and Endovascular Surgery, Hospital do Servidor Público Estadual, São Paulo, Brazil, between January 2015 and July 2017. RESULTS: In total, 86 femoropopliteal occlusive angioplasties were performed in 86 patients, with an initial technical success rate of 95.34%. The mean ± standard deviation follow-up time was 880 ± 68.84 days. The analysis was performed at 720 days. Technical failure occurred in four patients, who were excluded from the analysis, leaving 82 patients and 82 femoropopliteal occlusive angioplasties. The estimated primary patency, secondary patency, limb salvage, and overall survival rates at 720 days were 60%, 96%, 90%, and 82.5%, respectively. In univariate and multivariate analyses, Cox regression showed worse primary patency rates in patients with one tibial vessel or isolated popliteal artery runoff (p = 0.005), calcification grade 4 (p = 0.019), calcification grade > 2 (p = 0.017), small vessel diameter < 4 mm (p = 0.03) or primary angioplasty without stenting (p = 0.021). A univariate analysis showed worse limb salvage in patients with one tibial vessel or isolated popliteal artery runoff (p = 0.039). CONCLUSIONS: In this study, the main factors associated with worse outcomes in the endovascular treatment of femoropopliteal occlusive in terms of loss of primary patency were one tibial vessel or isolated popliteal artery runoff, calcification grade 4, or calcification grade > 2, small vessel diameter < 4 mm, and no stents use. One tibial vessel or isolated popliteal artery runoff was also associated with limb loss in a univariate Cox regression analysis.

Derivação com veias de membro superior após trombólise de aneurisma de artéria poplítea: alternativa para salvamento de membro / Arm vein bypass after popliteal artery aneurysm thrombolysis: an alternative for limb salvage

Os autores relatam um caso de aneurisma de artéria poplítea trombosado em que se realizou fibrinólise com sucesso na fase aguda. Foram utilizadas veias de braço para realização do enxerto e exclusão do aneurisma, pois o paciente havia sido previamente submetido à safenectomia bilateral e revascularização do miocárdio com as veias do outro braço. Apesar das dificuldades, o salvamento do membro foi alcançado.

The authors report a case of a thrombosed popliteal artery aneurysm successfully treated by fibrinolysis in its acute stage. Arm veins were used to perform a bypass and aneurysm exclusion, since the patient had previously been submitted to bilateral saphenous vein stripping and myocardial revascularization using the veins of the other arm. Despite the difficulties, limb salvage was achieved.
