“…[1][2][3][4] , as is the case with other limb arterial pathologies. 5,6 In 1969, Edwards described a technique for exclusion of the aneurysmal sac by means of proximal and distal ligation and autogenous vein interposition graft. 7 This technique avoids dissection of the aneurysm and reduces edema of the limb and the risk of vein or nerve lesion.…”

Popliteal artery aneurysms are frequent and may lead to thromboembolic events and limb loss. PURPOSE: To evaluate clinical and ultrasonographic follow-up of patients who underwent exclusion of a popliteal artery aneurysm using the technique proposed by Edwards. METHODS: Data of all patients who underwent surgery to repair a popliteal artery aneurysm at Hospital das Clinicas, the São Paulo University Medical School between 1996 and 2004 were reviewed. Inclusion criteria were repair with aneurysm exclusion and bypass using the technique proposed by Edwards, as well as the existence of preoperative and postoperative measurements of the aneurysmal sac. RESULTS: Data of 16 patients who underwent 20 procedures for popliteal artery aneurysm exclusion and bypass were available to analysis. The preoperative diameter of the popliteal artery aneurysms ranged from 1.3 cm to 6.1 cm (mean = 3.1 cm). Patients underwent duplex ultrasound scanning 1 month to 7 years after surgical repair. Follow-up of the 20 cases revealed that 10 aneurysms exhibited decreased mean transverse diameters, ranging from 0.2 to 2.3 cm, while 7 had increased in diameter, ranging 0.3 to 3.3 cm, and 3 remained unchanged. Flow was observed only in 5 outo f the 20 procedures, 3 of which (60%) had increased diameters. CONCLUSION: Although exclusion is a widely accepted procedure for the repair of popliteal artery aneurysms, data in the literature and the results of this study, which did not include cases of rupture or compression, suggest that strict follow-up of patients who undergo aneurysm exclusion is necessary.

Interrelationships between obesity, obstructive sleep apnea syndrome and cardiovascular risk in obese adolescents

et al. 2015

Background/ObjectivesObstructive sleep apnea syndrome (OSAS) may be a cardiovascular disease (CVD) risk factor independently of obesity in adults. Pediatric studies have associated OSAS with endothelial dysfunction, but few studies have examined relationships between OSAS and macrovascular sequelae. Our objective was to examine OSAS’s independent contribution to macrovascular CVD risk measures in obese adolescents.Subjects/MethodsThis cross-sectional observational study was conducted at Children’s Hospital of Philadelphia Clinical Research and Academic Sleep Centers, and University of Pennsylvania Vascular Research Unit. 31 obese non-diabetic adolescents underwent anthropometric measurements, overnight polysomnography, fasting laboratory draw, and cardiovascular imaging. Cardiovascular outcome measures included maximal carotid intima-media thickness (cIMTmax), a measure of carotid structural changes, and carotid-femoral pulse wave velocity (CFPWV), an aortic stiffness measure whose relationship vis-à-vis OSAS in children has not been previously examined. Carotid diameter and augmentation index (AIx, measuring central pressure augmentation from wave reflections) were assessed. Potential confounding variables examined included blood pressure, lipoproteins, high-sensitivity C-reactive protein, insulin and glucose.ResultsThe apnea hypopnea index, a primary OSAS measure, was not associated with cIMTmax, carotid diameter, CFPWV or AIx. BMI associated positively with cIMTmax (r=0.52, p=0.006) and CFPWV (r=0.45, p=0.01). Mean asleep end-tidal CO2 was negatively associated with carotid diameter (r=−0.63, p<0.0005). Insulin levels were negatively associated with AIx (r=−0.53, p=0.02).ConclusionsOSAS did not predict carotid structural changes or arterial stiffness independently of BMI in obese adolescents. Higher insulin levels associated with lower central pressure wave augmentation. Finally, long-term hypercapnia may predispose to carotid narrowing.

EDITORIALIn this second issue of the renamed Journal of Hospital das Clínicas, we start a new series of review articles in which a more in depth examination of themes is attempted. Our electronic editing is now operational, and we strongly invite future contributors to register and submit their manuscripts online (www.mdview.com.br/clinics) since we believe that this will greatly enhance the speed of publication. From the first to this second issue our time from acceptance of the manuscript to the physical appearance of the journal should be shrinking from 5½ to 4½ months. Ten articles on original research are being published.Xavier Vidal 1 evaluated the repair process of lesions in the ventricular myocardium of 26 rats with experimentally induced arterial hypertension induced by systemic blockade of nitric oxide. Blockade elevated arterial pressure and increased cardiac weight, causing wide infarcted myocardial areas, thickening of the muscular tunica with fibrosis, thickening in the wall of small arteries and arterioles, and wall fibrinoid necrosis to nearly complete luminal obliteration. Reparative fibrosis involved mainly oxytalan elastic and collagen fibers, which are considered of great importance for the post infarct repair process occurring during experimental nitric oxide inhibition.Wertzner et al. 2 evaluated speech emission in 40 children with and without phonological disorders by means of the Child Language Assessment phonology tests and two spontaneous speaking tests. Children with diagnosed phonological disorders predictably presented more distortions, but also a greater variability of response, with phonemes described by /s, z, / showing the highest frequency of occurrence.Szachnowicz et al. 3 estimated the prevalence of adenocarcinoma in 297 patients with Barrett's esophagus, and in 13 patients undergoing surgery, to conduct detailed macroscopic and microscopic analysis. Immunohistochemical tests for p53 and Ki67 were performed, correlating the type of tumor with its adjacent epithelium. In patients with Barrett´s esophagus, the prevalence of adenocarcinoma was
