Branch pulmonary artery stenosis is a common problem in pediatric cardiology. Treatment has included surgery, balloon angioplasty, and balloon expandable stent placement. It was the purpose of this investigation to demonstrate the cost-effectiveness of each of these modes of treatment. From 1983 to 1994 there were 30 patients admitted for treatment of branch pulmonary artery stenosis only. Data included age at procedure, sex, primary diagnosis, acute and intermediate term success, and complications. Acute success was defined by results at the end of the procedure where intermediate term (IT) success was defined by results at follow-up. Success of a procedure was defined by at least one of the following: an increase in vessel diameter by >/=50% of predilation diameter, a decrease in right ventricular to left ventricular or aortic systolic pressure ratio by >/=20%, or a decrease in peak to peak pressure gradient by >/=50%. The procedure was considered a failure if the previously mentioned criteria were not met or if the patient required a second procedure for the same stenosis. The expense of the procedure (estimated by using the patient charges) were collected from the time of the procedure until December 1994. Because of differing lengths of follow-up, the patients were analyzed separately for procedures and outpatient charges. The total charges were corrected to 1994 dollars using the Medical Consumer Price Index. Thirty patients had 46 separate procedures (12 patients had >1 procedure and 3 had >2 procedures). There were 13 surgeries, 13 balloon angioplasties, and 20 stents. Stents were the most successful (90% acute and 85% IT), but were not statistically superior to surgery (62% acute and IT). Balloon angioplasty was significantly less successful as compared with stents (31% acute and 23% IT), and was not statistically different from surgery over the acute and intermediate term. The charge data showed balloon angioplasty was the least expensive followed by stents and then by surgery. The average total charges per procedure, including outpatient charges, were: surgery $58,068 +/- $4372 (standard error), balloon $21,893 +/- $5019, stents $33,809 +/- $3533 (p < 0.001); excluding outpatient charges: surgery $52,989 +/- $3649, balloon $15,653 +/- $1691, and stents $29,531 +/- $2241 (p < 0.001). Average total charges per patient, including all procedure types and grouped by initial procedure, were: surgery $53,707 +/- $6388, balloon $50,040 +/- $8412, and stent $34,346 +/- $3488 (p = 0.047). Stents were at least as effective as surgery and were more effective than balloon angioplasty in both acute and intermediate term follow-up. Balloon angioplasty was least expensive per procedure but was also least effective. Therefore, intravascular balloon expandable stents are the most cost-effective means available in the treatment of branch pulmonary artery stenosis. |
