Use of the AFX Stent Graft in Patients with Extremely Narrow Aortic Bifurcation: A Multicenter Retrospective Study

Table 2

Preoperative artery dimensions. Data is derived from angulation-adjusted measurements and is presented as with min–max range for abdominal aortic aneurysm (AAA) and penetrating aortic ulcer (PAU). Student’s -test or Mann–Whitney test was applied according to the Kolmogorov-Smirnov normality test to identify differences between AAA and PAU patients ().

Target	AAA ()		PAU ()^Ψ		value	Total ()
		Min–max range		Min–max range			Min–max range
Max aortic diameter (mm)		34-72		23-72			23-72
Aortic bifurcation diameter (mm)		12-18		11-18			11-18
Max CIA left diameter (mm)		8-15		7-17			7-17
Min CIA left diameter (mm)		7-12		6-13			6–13
Max CIA right diameter (mm)		10-20		8-21			8–21
Min CIA right diameter(mm)		8-12		6-15			6-15
CIA length right (mm)		24-76		31-80			24-80
CIA length left (mm)		29-83		26-80			26-83
Max EIA left diameter (mm)		7-10		5.5-10			5.5-10
Min EIA left diameter (mm)		5.5-10		3-9			3-10
Max EIA right diameter (mm)		7-10		5-10			5–10
Min EIA left diameter (mm)		3-10		4.5-9			3-10
Max infrarenal aortic neck diameter (mm)		17-61		17-26			17-61
Infrarenal neck length (mm)		10-68		15-80			10-80

CIA = common iliac artery; EIA = external iliac artery; min = minimum; max = maximum. ^ΨIncluding one patient who was treated for a type Ib endoleak (EL) using the AFX stent graft (initial treatment for PAU).
