Đánh giá mức độ an toàn và tính khả thi của sử dụng Introducer Sheath 7F qua đường động mạch quay

Percutaneous coronary intervention (PCI) has evolved significantly, with the radial artery approach becoming increasingly preferred due to its lower incidence of bleeding complications compared to the femoral approach. However, for complex coronary interventions, the use of larger bore guiding catheters often necessitates larger Introducer Sheaths, typically 7F or 8F. The anatomical characteristics, particularly the radial artery diameter, in certain populations like Vietnamese patients, are generally smaller, posing potential challenges regarding the safety and feasibility of these larger sheaths. This study addresses a critical gap in local data by evaluating the safety and feasibility of using the 7F Introducer Sheath via the radial artery for complex coronary interventions in a Vietnamese clinical setting.

This prospective cross-sectional study investigated the safety and feasibility of using the 7F Introducer Sheath via the radial artery approach for complex percutaneous coronary intervention (PCI) in 63 Vietnamese patients at the Vietnam National Heart Institute between October 2023 and June 2025. The methodology involved evaluating the success rate of sheath placement and the incidence of vascular complications at the puncture site. Key findings revealed a 100% success rate for 7F Sheath placement, demonstrating its high feasibility. Complication rates were low, with radial artery spasm occurring in 11.1% of patients and hematoma in 9.5%, crucially, with no instances of severe complications such as acute radial artery occlusion, perforation, or arteriovenous fistula. The mean radial artery diameter was measured at 2.6 ± 0.2 mm, showing a positive correlation with patient height (r = 0.67, p < 0.001) and weight (r = 0.58, p < 0.001). Notably, females exhibited a significantly higher spasm rate (57.1% vs. 5.4% in males, p = 0.002), suggesting gender-specific considerations. The study concludes that employing the 7F Introducer Sheath via the radial artery is a safe and feasible option for complex coronary interventions in the Vietnamese population, offering a high success rate and minimal vascular complications, thereby supporting its broader application while advising careful consideration for female patients and those with hypertension who may have smaller radial artery diameters and higher spasm risk.
