Angiography is a common diagnostic and therapeutic procedure in patients with acute coronary syndrome (ACS). The complications are variable between mild self-limited complications to severe life-threatening complications which need early interventions.

New angiographic methods are associated with variable complications. Death, myocardial infarction, and stroke are among major angiography complications. In addition, some local complications including bleeding at the site of insertion, infection, arteriovenous fistula, pseudoaneurysm, and thrombosis is reported after angiography.

Radial and femoral methods are common angiographic methods. Its shown that radial method is associated with less complications and patients need shorter duration of hospitalization.

Radial artery thrombosis is common complication of radial angiography. However, the prevalence is between 5 to 19 percent but often it is not clinically important. Risk of ischemia due to thrombosis is low because of blood flow in radial and ulnar and collaterals. In patients with incomplete palmar arch this is important and may cause ischemia.

The aim of this study is to compare the outcomes of coronary angiography using Snuff-box deep palmar arch artery and radial artery in patients attending angiography center of Shahid Mohammadi hospital in Bandar Abbas in 2017.
