The radial artery is currently regarded as a useful vascular access site for coronary procedures. But there is no known impact of transradial coronary intervention (TRI) regarding the change of radial artery diameter. There were no published data regarding the change of radial artery diameter by quantitative artery analysis after the TRI.
From June 2009 to September 2012, consecutive patients underwent TRI and follow-up coronary angiography (FUCA) after TRI were enrolled. Retrograde radial artery angiography was performed before TRI in all patients. We analyzed the radial images of initial angiography and FUCA. We divided radial artery from an elbow to sheath tip into 5 parts (D1, D2, D3, D4 and D5) and analyzed radial artery diameter and minimal luminal diameter (MLD). The primary endpoint was the changes of radial artery diameter after TRI.
Among total 613 patients underwent FUCA, 103 patients underwent FUCA via other site (femoral artery or opposite radial artery) and 189 patients had no images of radial artery or the difficulty to analysis due to poor images. Finally, total 321 patients underwent FUCA via same site were analyzed. Before TRI, initial MLD1 was 1.58±0.52 and diameters were 3.06±0.63, 2.08±0.46, 1.96±0.46, 1.94±0.44 and 1.90±0.45 (D11, D12, D13, D14 and D15). MLD2 of FUCA was 1.48±0.51 and diameters were 3.13±0.58, 2.09±0.46, 1.95±0.45, 1.91±0.43 and 1.87±0.43 (D21, D22, D23, D24 and D25). The changes of radial artery size were not significant statistically. (p>0.05) But the change of MLD was statistically significant. (MLD1 vs. MLD2 p=0.034).
Although the minimal luminal diameter has shown a significant difference, the five measurements taken seem to support the idea that transradial interventions do not affect the radial artery size and the statistically significant difference was only 0.1 mm.
