Normal fibronectin levels after surgical treatment of portal hypertension in liver cirrhosis.

We found a significantly higher plasma fibronectin concentration in a group of nine cirrhotic patients who underwent surgical treatment for portal hypertension (either shunting and non shunting procedures) when compared to twenty non operated patients. Significantly shorter prothrombin time and activated partial thromboplastin time in the operated patients were found as well. These results might be related to an increased breakdown of fibronectin during consumption coagulopathy taking place in the extended collaterals and reversed in part by surgical treatment of portal hypertension complicating liver cirrhosis.

Fibronectin decrease in liver cirrhosis is related to spleen size.

We found a significantly lower plasma fibronectin concentration in cirrhotic patients than in controls, a significant inverse relationship between fibronectin and spleen size, but no correlation between fibronectin and hepatic blood flow, prothrombin time, or serum albumin. We suggest that the increased degradation in the enlarged spleen is more relevant than the decreased synthesis in reducing plasma fibronectin levels during liver cirrhosis with portal hypertension.

[Unreliability of the clinical diagnosis in deep venous thrombosis of the lower limbs].

277 patients subjected to phlebography for clinically suspect acute deep venous thrombosis of the lower extremities have been examined. Instrumental examination evidenced the presence of thrombosis in 140 of them (50.5%) while in the remaining 137 (49.5%) in whom venography proved negative, it was possible to define the pathologies responsible for the clinical picture in 89% of cases. In out-patients, the incidence of thrombosis proved lower (46%, 65/141 patients) than that presented by patients already hospitalised for other pathologies (55%, 75/136 patients). No significant differences were observed in the incidence of clinical symptoms and signs between patients with thrombosis and patients without at phlebography, while as regards the distribution of risk factors, there was a greater incidence of the following: age over-65, cancers, recent surgery and fractures of the lower extremities in the group of patients suffering from thrombosis. Personal experience would therefore appear to point to the total fallibility of the clinical diagnosis of deep venous thrombosis of the lower extremities and the consequent need for a constant objective instrumental diagnostic approach to this type of pathology.
