The total procedural time (RRA 14.1±6.3 minutes versus LRA 13.2±6.0 minutes; P=0.006) and fluoroscopy time (RRA 3.8±3.3 minutes versus LRA 3.4±2.8 minutes; P=0.046) were significantly shorter via LRA in comparison to RRA.
The dose of radiation (CAK: RRA, 320±205 mGy versus LRA, 302±173 mGy, P=0.09; CAK DAP: 28±20 Gycm versus 26±17 Gycm, P=0.13) and contrast volume (RRA, 63±14 mL versus LRA 62±17 mL; P=0.29) were not different between the two approaches (Table 3).
The total procedure time (RRA, 14.1±6.3 minutes versus LRA, 13.2±6.0 minutes; P=0.006), coronary time (RRA, 1.9 [1.4, 3.0] minutes versus LRA, 1.7 [1.2.9].9] minutes; P=0.001) and fluoroscopy time (RRA, 3.8±3.3 minutes versus LRA, 3.4±2.8 minutes; P=0.046) were significantly shorter via the LRA in comparison to the RRA.
The coronary procedural success rate was not different between the two approaches (RRA, 97.4% versus LRA, 97.1%; P=0.74).
The significant increase remained after adjustment on the previously mentioned confounding factors and OC use: RRa 2.12; 95% CI (1.31-3.43).
our institutional protocol is to do a routine pretherapy Dx-WBS for all patients referred for RRA 23.
9 Although the left radial approach (LRA) may reduce fluoroscopy time and cerebrovascular complications compared with RRA, 10– 12 several studies have also obtained conflicting results.
A total of 200 consecutive patients with STEMI who received primary PCI were randomized to LRA (number [n]=100) or RRA (n=100).
The adjusted Relative Risk of BC (RRa) was significantly increased for a total duration of OC use longer than 72 months (RRa 2.80; 95% CI 1.56-5.01), as well as the RRa for OC use above 48 months before FFTP (3.26 95% CI 1.37-7.76) and, to a lesser extent, the RRa for OC use above 48 months after FFTP (2.02 95% CI 1.07-3.84) respectively.
An important study called "IoN trial" is currently undertaken by 32 centers from UK, where surgically ablated (R0) LR DTC patients are recruited and randomized to either receive low-dose (1110 MBq) RRA or no RRA 6.
Initial CS counseling applies to high risk farmers defined by the above mentioned rapid and detailed risk assessment (RRA ≥70th percentile of all RRA scores and DRA ≥ 80th percentile of all DRA scores respectively).
