We report the relations between comorbidities and chronic venous disease. In this cross-sectional study, information was gathered from 1679 Serbian patients. The majority (65.0%) of patients were women. Mild forms of chronic venous disease (clinical, etiologic, anatomic and pathophysiologic [CEAP] classification; C0s-C1) were more frequent in women (11.6%), while severe forms (CEAP C4-C6) were more commonly encountered in men (42.1%). The most frequent comorbidity was emphysema/chronic obstructive pulmonary disease in both groups (74.3% in males and 70.6% in females). For females, diabetes mellitus (P <.005), arterial hypertension (P <.000), and skeletal/joint diseases (P <.042) were more commonly found in the C4 to C6 category. Both males and females, with severe form of chronic venous disease, may benefit from additional screening for comorbidities. Further studies are needed to clarify the nature of association among comorbidities and chronic venous disease. © The Author(s) 2014.

We evaluated the prognostic value of copeptin levels in a cohort of surgical patients after elective carotid endarterectomy (CEA). Twenty-one patients with perioperative stroke were prospectively recruited. The diagnosis of cerebrovascular event (CVE) was confirmed by computed tomography. Additionally, 21 patients with CEA without any complications (control patients) were enrolled. Blood samples were taken within 3 hours of the symptom onset. Circulating copeptin level was significantly higher in patients with CVE when compared to controls (P =.025), and significantly higher in nonsurvivors than in survivors (P =.030) after CVE. Plasma concentrations of interleukin 6 (IL-6) and C-reactive protein (CRP) were also elevated in patients with CVE (IL-6: P =.043; CRP: P =.002). We conclude that the activation of the stress axis in patients with CEA results with copeptin elevation, but more so in patients with perioperative stroke. Copeptin may be a helpful biomarker for stroke risk assessment in patients after CEA. © The Author(s) 2013.

Objectives: Multiple areas of stenosis and different levels of obstruction of internal jugular and azygous veins (a condition known as cronic cerebrospinal venous insufficiency) recently emerged as an additional theory to the well-known autoimmune concept, explaining etiology of multiple sclerosis (MS). The aim of our study was to evaluate internal jugular vein (IJV) morphology and haemodynamic characteristics in patients with MS and compare it with well-matched healthy individuals and to evaluate the prevalence of venous flow abnormalities in both groups. Methods: Sixty-four patients with clinically proven MS and 37 healthy individuals were included in our study. In all patients, IJV morphology and haemodynamic characteristics were evaluated by colour Doppler sonography as well as venous flow disorder. The patients were classified into four groups according to MS clinical form presentation. The prevalence of morphological and haemodynamic abnormalities in the IJV were assessed. Results: The presence of stenosing lesion, mostly intraluminal defects like abnormal IJV valves, were observed in 28 patients (43%) in the MS group, and in 17 patients (45.9%) in the control group (P = NS). By adding haemodynamic Doppler information in the IJV venous outflow was significantly different in 42% of MS patients showing flow abnormalities (27/64), as compared with 8.1% of the controls (3/37), P< 0.001. Conclusion: In our group of patients, patients suffering from MS had significantly more IJV morphological changes and haemodynamic abnormalities when compared with healthy individuals not suffering from MS. These findings can be well demonstrated by noninvasive and cost-effective Doppler ultrasound.

Background: To evaluate safety, short and long-term graft patency, clinical success rates, and factors associated with patency, limb salvage and mortality aft er surgical reconstruction in patients younger than 50 years of age who had undergone unilateral iliac artery bypass surgery. Patients and methods: From January 2000 to January 2010, 65 consecutive reconstructive vascular operations were performed in 22 women and 43 men of age < 50 years with unilateral iliac atherosclerotic lesions and claudication or chronic limb ischemia. All patients were followed at 1, 3, 6, and 12 months aft er surgery and every 6 months thereaft er. Results: Th ere was in-hospital vascular graft thrombosis in four (6.1 %) patients. No in-hospital deaths occurred. Median follow-up was 49.6 ± 33 months. Primary patency rates at 1-, 3-, 5-, and 10-year were 92.2 %, 85.6 %, 73.6 %, and 56.5 %, respectively. Seven patients passed away during follow-up of which four patients due to coronary artery disease, two patients due to cerebrovascular disease and one patient due to malignancy. Limb salvage rate aft er 1-, 3-, 5-, and 10-year follow-up was 100 %, 100 %, 96.3 %, and 91.2 %, respectively. Cox regression analysis including age, sex, risk factors for vascular disease, indication for treatment, preoperative ABI, lesion length, graft diameter and type of pre-procedural lesion (stenosis/occlusion), showed that only age (beta-0.281, expected beta 0.755, p = 0.007) and presence of diabetes mellitus during index surgery (beta-1.292, expected beta 0.275, p = 0.026) were found to be significant predictors of diminishing graft patency during the follow-up. Presence of diabetes mellitus during index surgery (beta-1.246, expected beta 0.291, p = 0.034) was the only variable predicting mortality. Conclusions: Surgical treatment for unilateral iliac lesions in patients with premature atherosclerosis is a safe procedure with a low operative risk and acceptable long-term results. Diabetes mellitus and age at index surgery are predictive for low graft patency. Presence of diabetes is associated with decreased long-term survival. © 2011 by Hans Huber Publishers, Hogrefe AG, Bern.

To analyze the outcome of urgent carotid endarterectomy (CEA) performed within less than six hours in patients with crescendo transient ischemic attack (TIA) and stroke in progression. From January 1998 to December 2008, 58 urgent CEAs were done for acute neurological ischemic events - 46 patients with crescendo TIA and 12 patients with stroke in progression. Brain computed tomography (CT) was done prior and after the surgery. Disability level was assessed prior to and after urgent CEA using modified Rankin scale. Median follow-up was 42.1 ± 16.6 months. In the early postoperative period stroke rate was 0% for the patients in crescendo TIA group while in patients with stroke in progression group 3 patients (25%) had positive postoperative brain CT, yet neurological status significantly improved. Mid-term stroke rate was 2.2% in crescendo TIA group and 8.3% in stroke in progression group. In the early postoperative period there were no lethal outcomes, mid-term mortality was 8.3% in stroke in progression while in crescendo TIA group lethal outcomes were not observed. In conclusion, based on our results urgent CEA is a safe and effective treatment option for patients with crescendo TIA and stroke in progression with acceptable rate of postoperative complications. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.
