Webpinchoff is locally determined and independent of initial conditions, we anticipate that lengths in the pinchoff re-gion, both axial and radial, might scale as µ gt2 r ¶ 1y3. (4) To see this behavior in the numerical solutions, we plot in Fig. 2 R3y2 against actual time t for two distinct points R min and R nose on the pinchoff shape from one ... Grades of abnormality. grade 0: no narrowing in the catheter's course. grade 1: deviation of the catheter with no luminal narrowing. grade 2: luminal narrowing as the catheter passes under the clavicle (pinch-off sign) grade 3: transection of the catheter between the clavicle and the 1st rib with embolization of the distal catheter 1.
