Some states award delegates to candidates on a winner-take-all basis, meaning that the candidate with the most votes in a state is awarded all of that state's delegates. Other states award delegates in proportion to each candidate's share of the primary vote.
Provocative angiography involves a full diagnostic angiogram followed by administration of intra-arterial procoagulant agents to identify an occult bleeding source in patients who have normal test results after lower gastrointestinal bleeding.
The test is also called a peripheral arteriogram. 1  A thin tube (catheter) that doctors insert into your artery during a peripheral angiogram damages the artery. 2  Emergency surgery may be needed to restore blood flow to the artery. 3  People have allergic reactions to the dye used in the test.octors use a peripheral angiogram if they think blood is not flowing well in the arteries leading to your legs or, in rare cases, to your arms. The angiogram helps you and your doctor decide if a surgical procedure is needed to open the blocked arteries. Peripheral angioplasty is one such procedure.
