Management and timing of access-site vascular complications occurring after trans-radial percutaneous coronary procedures

Background: Access-site vascular complications (ASVC) in patients undergoing trans-radial coronary procedures are rare but may have relevant clinical consequences. Data regarding the optimal management of radial-access-related ASVC are lacking. Methods: During a period of 6 years we prospectively collected ASVC. ASVC were defined as any complication requiring ultrasound examination or upper limb angiography. ASVC were categorized according to the timing of diagnosis: "very early" (in the cath lab), "early" (after cath lab discharge, but during the hospital stay) and "late" (after hospital discharge). The need of surgery (primary end-point) and the development of neurological hand deficit (secondary end-point) were assessed. Results: Fifty-seven radial-artery related ASVC were collected. ASVC diagnosis was obtained by upper limb angiography in 25 patients (44%) and by Doppler in 32 patients (56%). Surgery was required in 6 cases (11%), the remaining patients receiving successful conservative management (which included prolonged local compression). Three patients (who received surgery) exhibited a mild neurological hand deficit in the follow-up. Need for surgery differed significantly according to timing of diagnosis as it occurred in 1 of 26 patients (3.8%) with "very early" diagnosis, in 1 of 21 patients (4.8%) with "early" diagnosis, and in 4 of 10 patients (40%) with "late" diagnosis (p = 0.026). Conclusions: ASVC are diagnosed with different timing after trans-radial procedures. Conservative management including local compression allows successful management in the majority of ASVC. Prompt recognition is pivotal as late diagnosis is associated to the need for surgery.
