Histological analysis of proliferating tissue. (a) Macroscopic analysis of proliferating tissue 2 and 4 weeks after surgery. Scale bar = 3 mm. (b) Histological analysis of proliferating tissue (azan stain) 4 weeks after surgery in the bare platinum (BP) and hydrogel coil groups. Scale bar = 250 μm. (c) Thickness of proliferating tissue covering the aneurysmal orifices. Data are expressed as mean ± standard error of three swine in each group. between the two groups.
