Mesenteric arteriovenous shunt associated with thrombosis of the portal venous system: case report.

We report a rare case of mesenteric arteriovenous shunt associated with thrombosis of the portal venous system. The angiographic features consisted of new vessel formation, thrombosis of the main portal vein, superior mesenteric vein and branches, and early filling of distal mesenteric veins with hepatopetal collateral flow. This phenomenon may be due to new vessel formation within the portal vein thrombosis and active lysis of the thrombus exposing the organizing vessels to the distal superior mesenteric veins.

[Postoperative radiotherapy with the electron beam in breast cancer].

The usefulness of postoperative radiotherapy for breast cancer was investigated in 152 patients. A dose of 50 Gy was given to the axillar, supraclavicular and internal mammary lymphnode areas using a 12 MeV electron and to the chest wall using a 6 MeV electron. The five and 10-year survival rates were 79.
