BACKGROUND AND PURPOSE Deep venous reflux resolution after great saphenous vein surgery has been reported, but the studies evaluated mainly patients with deep segmental reflux. We prospectively analyzed the effects of greater saphenous vein ablation on coexisting primary deep axial venous reflux compared with segmental venous reflux. Patients and methods Between February 1997 and June 2001, pat...

FIGURE 8-12 International system of radiographic grading of vesicoureteral reflux (VUR). The severity of VUR is most frequently classified according to the International Grading System of Vesicoureteral Reflux, using a standardized technique for performance of voiding cystourethrography. The definitions of this system are illustrated in Figure 8-4 and are as follows. In grade I, reflux only int...

In 3646 children with at least one confirmed urinary tract infection the prevalence of vesicoureteric reflux at presentation was correlated with progressive renal damage during follow up of not less than two and up to 16 years. Reflux was not demonstrated either at presentation or at any subsequent time in almost one half of the children who suffered progressive renal damage and was not a risk ...

Background: Ulcer is a severe complication from chronic venous insufficiency; thus, its pathophysiology needs to be deeply understood. Venous Doppler ultrasonography is the most appropriate complementary imaging study, enabling the study of the superficial and deep venous system, the diameter and flow of the veins. Recent studies have suggested that popliteal vein reflux is an important factor ...

Gastro-esophageal reflux disease (GERD) is the result of the acid contents regurgitation back from the stomach into the esophagus. According to the endoscopic findings, GERD can be divided into two main forms: non-erosive (NERD) and erosive reflux esophagitis. The pathogenesis of GERD is associated with the impaired function of the antireflux barrier. Disturbances of the autonomic nervous syste...

OBJECTIVE We undertook this cross-sectional study to investigate the distribution of venous reflux and effect of axial reflux in superficial and deep veins and to determine the clinical value of quantifying peak reverse flow velocity and reflux time in limbs with chronic venous disease. PATIENTS AND METHODS Four hundred one legs (127 with skin changes, 274 without skin changes) in 272 patient...

Chronic venous disease (CVD) is the most prevalent form of vascular disease, affecting about a third of adult Americans. Most patients present with varicose veins but swelling and skin damage are common as well. The signs and symptoms of CVD are result of venous hypertension that develops from reflux, obstruction or a combination of both. In patients with CVD, around 70-80% will have superficia...

Background: The major responsibility of an anesthesiologist is to provide adequate respiration for the patient. The most vital element in providing functional respiration is the airway. No anesthetic is safe unless diligent efforts are devoted to maintaining an intact functional airway. Difficult intubation had been classified into four grades, according to the view obtainable at laryngoscopy b...

Background: Incomplete ureteric duplication can be associated with either ureteropelvic obstruction involving the lower moiety or reflux between the ureters (yo-yo reflux). Yo-yo reflux can be a cause of repeated urinary tract infection with subsequent renal damage. Aim of the work: The current study evaluated the presence of yo-yo reflux as reason of upper moiety dilation in cases with incompl...
