1/6. Hemosiderotic fibrohistiocytic lipomatous lesion: clinical correlation with venous stasis.Hemosiderotic fibrohistiocytic lipomatous lesion (HFLL) is a recently proposed lipomatous entity. HFLL was originally suggested to be a benign reactive lesion arising due to an antecedent trauma. We report two patients with HFLL who also suffered from chronic vein insufficiency due to varicose involving deep veins of the low limbs. Both patients were middle-aged women with solitary, poorly circumscribed subcutaneous lesions on the lower extremities. Histopathological examination revealed typical features of HFLL. We think that the consistent clinical features such as advanced age, female sex predilection, and specific location along with distinctive histopathological features allow the suggestion that impaired blood circulation, to wit, venous stasis is involved in the pathogenesis of HFLL. We hypothesize that the proliferation of spindled fibroblastic and myofibroblastic cells and capillaries, erythrocyte extravasation, and hemosiderin deposition with lipomatous tissue of HFLL may simply represent an exaggerated tissue response to venous stasis in which elevated venous and capillary pressures, oxygen saturation, and edema stimulate the proliferation of the above mentioned elements and lead to erythrocyte extravasation. A similar histopathological pattern is seen in acroangiodermatitis of mali and vascular transformation of lymph node sinuses, and these conditions are also associated with impaired blood circulation.- - - - - - - - - - ranking = 1keywords = insufficiency (Clic here for more details about this article) |
2/6. coinfection of schistosoma mansoni and strongyloides stercoralis in a patient with variceal bleeding.We report a case of hepatosplenic schistosomiasis with portal hypertension and variceal bleeding in an immigrant patient from egypt, coinfected with strongyloides stercoralis. The diagnosis was based on the following: (a) identification of schistosoma mansoni ova in the stools and colonic biopsy specimens, (b) portal hypertension and esophageal varices with normal liver function and the absence of hepatic cirrhosis stigmata, (c) history of migration from an endemic area and (d) ultrasonographic findings of spleen and liver enlargement, fibrosed portal tracts, and normal lobular architecture of liver parenchyma. Hepatosplenic schistosomiasis should be suspected in any patient from an endemic area who has splenomegaly, portal hypertension, and esophageal varices bleeding in the absence of stigmata of liver cirrhosis and hepatic insufficiency. coinfection with S. stercoralis could be attributed to common epidemiological features of the parasites and the patient's habits.- - - - - - - - - - ranking = 1keywords = insufficiency (Clic here for more details about this article) |
3/6. venous insufficiency in a young man secondary to a traumatic arteriovenous fistula.The medical history in a young man who developed varicose veins and venous insufficiency secondary to an acquired arteriovenous fistula in the thigh is presented. The radiological and clinical findings are discussed. The disease process in the development of varicose veins is not fully understood and cannot be satisfactorily explained as a consequence of arterial pressure within the venous system or a defect in the venous valves alone. The widespread ectatic changes seen within the venous system in our patient suggests the activation of an unknown, possibly humoral factor, resulting in morphological modifications in the vein wall.- - - - - - - - - - ranking = 5185.9542299826keywords = venous insufficiency, insufficiency (Clic here for more details about this article) |
4/6. Regression of multiple pulmonary varices after mitral valve replacement.A 30-year-old woman with severe mitral insufficiency had large, rounded opacities at the right hilus as seen on her chest x-ray film. These were shown to be varicosities of the right pulmonary veins by pulmonary angiography and by direct injection of contrast medium from a Brockenbrough catheter, which entered the varices from the left atrium. A year after mitral valve replacement there was complete regression of the venous dilatations. When a pulmonary varix is detected there is associated heart disease in 40% of cases. mitral valve disease (usually mitral insufficiency) is the cardiac abnormality in 27%. This would indicate that pulmonary varix is a complication of mitral insufficiency. Four patients who have undergone valve replacement for mitral reflux have shown regression of the caricosities, suggesting that relief of mitral insufficiency will reduce or eliminate the risk of varix rupture.- - - - - - - - - - ranking = 4keywords = insufficiency (Clic here for more details about this article) |
5/6. varicose veins combined with mucoid degeneration of the venous wall.We report on a 56-year-old woman with bilateral chronic venous insufficiency, a cavernous hemangioma at the right thigh and an aneurysm of the left femoral vein, without bone or soft tissue hypertrophy. Histopathology revealed a mucoid degeneration of the media musculature of the venous wall. Such a finding has not yet been described in the world literature. The differential diagnosis must consider a secondary hitherto unknown alteration of varicose veins, a variety of a vascular malformation not yet described, and a primary degeneration of the smooth muscles of the vascular wall followed by the development of varicose veins.- - - - - - - - - - ranking = 5181.9542299826keywords = venous insufficiency, insufficiency (Clic here for more details about this article) |
6/6. Long-term follow-up of a superficial femoral vein injury: a case report from the vietnam Vascular Registry.We report a 29-year follow-up of a high-velocity superficial femoral vein injury sustained during the vietnam war that was treated by emergent ligation. After years of suffering recurrent ulceration from chronic venous insufficiency, this patient underwent axillary vein valve transfer with improvement in his venous hypertension. Long-term follow-up of patients with deep venous injuries is necessary to avoid complications from chronic venous insufficiency.- - - - - - - - - - ranking = 10363.908459965keywords = venous insufficiency, insufficiency (Clic here for more details about this article) |
