High-level minimally incised procedure safety demonstrated through blood vessels on the back of the hand during cardiovascular procedures

Unlike conventional cardiovascular procedures, which were done through the wrist, the snuffbox approach uses distal radial vessels in the back of the hand, which has the advantage of reducing complications such as bleeding due to low risk of vascular occlusion and easy hemostasis after the procedure.
However, the blood vessels on the back of the hand were small in diameter, making it difficult to apply thick instruments required for complex procedures, so they were rarely used for high-level procedures. Therefore, this study analyzed the safety of complex cardiovascular procedures using a thin seven-french conduit, although the diameter is larger than that of a six-french conduit that was mainly used in the past.
The research team of professors Noh Ji-woong and Lee Oh-hyun of the Department of Cardiology at Yongin Severance Hospital (co-author) and Kim Yong-cheol and Cho Deok-gyu (co-corresponding author) analyzed the safety and effectiveness of the procedure on 100 patients with angina and myocardial infarction who underwent cardiovascular procedures at Yongin Severance Hospital from August 2021 to April 2024.
In our study, cardiovascular procedures with the snuffbox approach were successful in all 100 participating patients, including those with complex lesions with high difficulty in the procedure and high risk of complications, and none of the significant complications at the site of the procedure, such as wrist vascular obstruction, occurred. In addition, intravascular imaging immediately after the procedure showed very rare intima damage or thrombus formation in wrist-site blood vessels, and all patients recovered quickly without impaired hand function.
Professor Kim Yong-chul said, "This study is the first in Korea to prove that the snuffbox approach using a thin-walled seven-french conduit can be safely applied to complex cardiovascular procedures that were previously difficult. It is significant as a way to seek rapid recovery by preserving wrist blood vessels after cardiovascular procedures."
Professor Noh Ji-woong said, "The snuffbox approach is the best approach to lower the risk of pain and bleeding after the procedure, and to increase the likelihood of future vascular reuse without affecting hand function." "It can be a new alternative, especially for patients with difficulty accessing leg arteries, such as the elderly or chronic kidney disease."," he stressed.
The results of the study were recently published in the sister journal of Nature 'Scientific Reports'.
