An update in varicose vein pathology after ten years of endovenous laser therapy (EVLT) with a 980 nm diode laser: clinical experience of a single center.

AIM: To show our experience in the surgical treatment of superficial vein insufficiency of the lower limbs. SUBJECTS AND METHODS: Since 2002 we have performed 659 procedures of endovascular laser therapy (EVLT) (group A) in the treatment of chronic venous insufficiency of the great saphenous vein using a 980 nm diode laser. A closely matched group of 100 patients (50 Group A, 50 Group B) with homogeneous clinical findings (CEAP classification) was controlled with a mean follow-up of 18 months in our more recent experience (3 years). Most patients operated on in this period were lost to follow-up. RESULTS: The Final results showed that EVLT can be used only in a specific selected group of cases based on anatomy and hemodynamics and while 980 nm EVLT could not be selected as the best treatment for this pathology, it could be placed side by side with conventional therapy. CONCLUSIONS: In our one year's more recent experience, we observed an increased number of patients treated with conventional therapy. The development of new laser tools (new wavelengths and continuous radial laser) and the improvement of clinical follow up may lead us to a more correct application of EVLT in the absence of randomized trials because of widespread clinical findings and poor pathological follow-up of this approach to superficial venous insufficiency.

Penile duplex pharmaco-ultrasonography of cavernous arteries in men with erectile dysfunction and generalized atherosclerosis.

Assessment of cavernosal perfusion in men with erectile dysfunction (ED) relies on Doppler spectrum analysis of pharmachologically stimulated peak systolic velocity (sPSV) in cavernous arteries but its accuracy in identifying men affected by a cavernosal perfusion disorder correlated with atherosclerosis remains undefined. We estimated by B-mode ultrasound, the accuracy of sPSV of cavernous arteries to identify ED with an expected cavernosal perfusion disorder. This was predicted by an elevated intima-media thickness (IMT) of common carotid arteries, a reference methodology to estimate the degree of generalized atherosclerosis, in men exposed to vascular risk factors (VRFs). sPSV and IMT were evaluated in 269 men with ED, 49 had no VRFs, 100 were overweight with/or without hyperlipidaemia, 120 were affected by type 2 diabetes and/or essential hypertension. sPSV was significantly lower (p<0.05) in patients with VRFs associated with atherosclerosis (IMT>or=1 mm) (n=39) than in men with no VRFs and no atherosclerosis (n=49). sPSV correlated negatively with age (p<0.0001), with serum% of glycated haemoglobin (p=0.010) and with carotid artery IMT (p=0.013). An sPSVor=1 mm combined to the exposure to VRFs. The ultrasonographic evaluation of sPSV had a very limited accuracy in discriminating ED with an expected cavernosal perfusion disorder, based on the presence of a generalized atherosclerosis in men with VRFs.

Intima-media thickening of common carotid arteries is a risk factor for severe erectile dysfunction in men with vascular risk factors but no clinical evidence of atherosclerosis.

PURPOSE: The association of erectile dysfunction (ED) with vascular damage in men without clinical atherosclerosis is unknown. By B-mode ultrasound we evaluated intima-media thickness (IMT) of common carotid arteries, a measure of vascular damage, in men reporting ED with or without vascular risk factors (VRFs) but no clinical atherosclerosis. MATERIALS AND METHODS: IMT of common carotid arteries was evaluated in 270 men with ED. A total of 50 men (mean age +/- SD 39.84 +/- 12.5 years) had no VRFs, 100 (mean age 47.92 +/- 10.94 years) were overweight and/or had hyperlipidemia, and 120 (mean age 53.95 +/- 9.73 years) were affected by type 2 diabetes and/or essential arterial hypertension. RESULTS: IMT was significantly lower in men with no VRFs compared to men with VRFs (p <0.05), and correlated with the severity of ED evaluated through the Sexual Health Inventory for Men (p = 0.0008). Of men with VRFs 17.7% (39 of 220) showed an IMT score indicative of vascular damage (1.00 mm or greater), while only 1 man with no VRFs had a high IMT. Men with VRFs and a high carotid IMT score demonstrated more severe ED, were older and had a higher serum level of C-reactive protein compared to men with VRFs and an IMT of less than 1.00 mm (p <0.05). A high IMT score but not an increased measure for each VRF, including aging, significantly increased the risk of severe ED (odds ratio 2.6, confidence interval 1.1 to 5.9) even after controlling for smoking and drugs associated with ED. CONCLUSIONS: ED in men with VRFs was the only clinical correlate of unrecognized atherosclerosis of common carotid arteries.

Abdominal aortic intramural hematoma related to penetrating ulcer: an inappropriate indication for endovascular repair?

PURPOSE: To present a rare case of abdominal aortic intramural hematoma with penetrating ulcer. CASE REPORT: A 68-year-old hypertensive lady was admitted with chest pain. An echo Doppler abdominal study showed a 2.5-cm-diameter abdominal aorta with periaortic blood flow. Urgent computed tomography documented a 4-cm aneurysmal dilatation, 4 cm long, at the infrarenal level of the inferior mesenteric artery origin, which appeared on the angiogram as a very short lateral bleb. At elective open laparotomy, no true abdominal atherosclerotic aneurysm was found in the retroperitoneal space, but rather, an intramural hematoma with ulcer. An aortobi-iliac graft was inserted, and the patient was discharged with a good outcome. Histological examination of the explanted tissue confirmed adventitial calcifications, organized thrombus in the hematoma, and intimal neovascularization. CONCLUSIONS: Considering the pathology, this case was more appropriately treated with open surgery, although endovascular repair was not excluded as an option.

Endothelial cell activation in men with erectile dysfunction without cardiovascular risk factors and overt vascular damage.

PURPOSE: Endothelial cell activation (ECA) is an initiating event in atherosclerosis. Biochemical measures of ECA were evaluated in patients with erectile dysfunction (ED) associated or not associated with cardiovascular risk factors (VRFs) to assess whether ED is a sentinel of atherosclerosis. MATERIALS AND METHODS: Circulating soluble P-selectin, intercellular adhesion molecule-1, vascular cell adhesion molecule-1 and endothelin-1 concentrations were assessed in 45 men with ED but no VRFs, 45 men with ED associated with VRFs and 25 healthy men. Ultrasound intima-media thickness of carotid arteries and pharmacologically stimulated peak systolic velocity of cavernous arteries were used to assess vascular damage. RESULTS: Measures of ECA were higher in men with ED but no VRFs than in controls (p <0.01) and all were comparable among groups of men with ED. Levels of endothelin-1 in men with ED and no VRFs versus healthy men of the same age resulted in the best independent predictor for ED after adjusting for the confounding effect of increased body mass index and smoking (OR 5.37, 95% CI 2.12 to 19.70). Intima-media thickness of carotid arteries was comparable in controls and in men with ED but no VRFs, and ruled out the bias of overt damage of large arteries in the latter. Peak systolic velocity of cavernous arteries excluded vasculogenic ED in the majority of patients with no VRFs. CONCLUSIONS: Increased biochemical measures of ECA were associated with ED independent of coexisting VRFs and overt vascular damage, suggesting that ED is a sentinel of early atherosclerosis.
