Abstract

A 42-year-old woman with mixed connective tissue disease (MCTD) died due to the rupture of esophageal varices. The autopsy revealed fresh thrombi in the main trunk of the portal vein. Microscopic examination disclosed wide- spread periportal fibrosis and stenosis of peripheral portal veins without remodeling of hepatic lobular architecture, which was compatible to idiopathic portal hypertension (IPH). Anti-phospholipid antibody was negative. Accordingly it is likely that portal vein thrombosis developed secondary to IPH. In the literature 6 (37.5%) of 16 collagen vascular disease patients with IPH died, and three of them were due to rupture of esophageal varices. Therefore IPH should be considered to be one of the most important complications affecting its grave prognosis in patients with collagen vascular disease. The patient also had had pulmonary hypertension (PH) when the diagnosis of portal hypertension was made. In the literature we found 5 collagen vascular disease patients with both PH and IPH like this case. The most outstanding common clinical feature among these 6 patients was Raynaud's phenomenon associated with positive anti-RNP antibody. Moreover 5 of 6 cases including this case simultaneously developed both PH and IPH. The clinical course of these patients suggests there may be a common pathogenetic factor for these two lesions. A possible candidate involved in the pathogenesis of PH and IPH may be endothelin, one of the vasoactive substances, since its receptor is said to be expressed abundantly in pulmonary and portal vasculatures. However, further investigation is necessary to elucidate the mechanism of PH and IPH in collagen vascular diseases.
