![(A) Angiogram of the cavopulmonary anastomosis and pulmonary arteries before Fontan operation. The vessel diameter and the body surface area (BSA) are shown. Stenosis of the central part of left pulmonary artery (LPA) is visible. The peripheral pulmonary vessels are well developed. The pulmonary artery index (Nakata index ; [ (RPA 2 LPA 2 )/4]/BSA mm 2 /m 2 ) is 158 mm 2 m 2 ; the total lower lobe index ([ (RLLA 2 LLLA 2 )/4]/BSA mm 2 /m 2 ) is 145 mm 2 /m 2 .

Context 1
... all postoperatively catheterized consecutive patients operated on in our institution between 1992 and 2005 (n 73 of the total of 124), the diameter of the central and lower lobe PA was measured preoperatively and postop- eratively using contrast angiography in the systolic phase according to the original method published by Nakata and colleagues [6] and Reddy and associates [7] and our previously published data [15,16], as shown in Figure 1. The general indications for postoperative catheterization have been described elsewhere [17]. ...

... PA diameters did not show any increase during follow-up, either for the central PAs or for the lower lobes Fig 1). Consequently, the BSA-dependent PAI and LLI (preoperative median, 261 and 138 mm 2 /m 2 , respectively) decreased significantly from the preopera- tive examination to the end of the follow-up (median, 177 and 109 mm 2 /m 2 , respectively; p 0.001; Fig 2). ...
Context 3
... lowest PAI was noted in patients with the longest fol- low-up (Fig 3; r 0.5; p 0.009), whereas the age of the patients at the postoperative catheterization showed no correlation with PAI. A statistically significant correlation was found between a low PAI (150 mm 2 /m 2 ) at the end of the follow-up and the incidence of an unfavorable Fontan outcome (Fig 4; n 10; p 0.002). Also, in patients who died (n 4) there was a correlation with low PAI (p 0.011), especially accompanied by elevated PA pressure (PAP; p 0.001). ...

Conference Discussion:
Have you compared this group with the single-lung Fontan?
But my question, actually, if we consider this as single lung, whatever the cause of the hypoplasia of the pulmonary artery, absent or have been taken in the shunt, whatever, and you do it just a single-lung
Fontan, and you compare this with the intrapulmonary septati...
