Comparison of Artificial Intelligence Versus Radiologist Interpretation of Right Ventricular to Left Ventricular Ratio for Pulmonary Embolism Response Team Activations at a Tertiary Referral Center

both groups.Mean preoperative VCSS were 9.4 and 10.9 in the RFA and MFA groups, respectively (P .05).More venous ulcers were present at the time of MFA (n 16; 25.8%) than RFA (n 11; 11.7%) (P .015).Median follow-up was 164.5 days in the RFA cohort and 156 days following MFA.Symptomatic improvement after RFA and MFA was 91% and 88%, respectively.Mean postoperative VCSS decreased from 9.4 to 7.3 in the RFA group and 10.9 to 9.2 following MFA.Immediate vein closure was achieved in 98% of limbs in both groups; two late recanalizations occurred following MFA but none following RFA.Ulcer healing was higher following MFA (n 13; 21% vs n 10; 8.3%; P .015).The incidence of ARTE was 4.8% (n 3) following MFA and 1.7% (n 2) following RFA (P .52).One gastrocnemius DVT occurred in the MFA group.No pulmonary emboli or central nervous complications occurred.All adverse thrombotic events were asymptomatic and resolved with short-term anticoagulation.Superficial phlebitis was higher following MFA (n 11; 17.7% vs n 5; 4.2%; P .002)One postoperative sural neuralgia occurred after RFA.Conclusions: RFA and MFA are both safe and effective treatments for patients with symptomatic, incompetent SSVs.Both resulted in excellent symptomatic relief and early truncal vein closure rates.Ulcer healing rates were superior in the MFA group.Adverse thrombotic events following RFA were low and consistent with other contemporary studies, although superficial phlebitis was more frequent following MFA.
