Dynamic images of SR angiography showing the collateral circulation between the external maxillary artery (EMA) and the pterygopalatine artery (PPA) after external carotid artery transection. (A) SR angiography imaging (a) in rat after ECA transection and middle cerebral artery occlusion and (b) diagram of the anastomoses between the PPA and the EMA. (B) The dynamic figures with contrast enhancement (a–j) showing the time course of EMA appearance after ECA transection performed by SR angiography. The images show that the contrast agent flowed from the PPA (large arrowheads) to the EMA (small arrowheads) through the ABTP (arrows). ICA: internal carotid artery. Scale bar: 1 mm.
