Systemic-to-pulmonary collateral vessels and shunts: treatment with embolization.

abstract：:The effects of increasing single selective doses of prostaglandin E1 (PGE1) on superior mesenteric arterial flow and portal and systemic blood pressures were studied in dogs to assess its value as a vasodilatory agent for pharmacoangiography. PGE1 consistently increased blood flow, with an average increase of 187%, bu...
