Stone JR: Coarctation of the aorta with poststenotic
aneurysm in a 71-year-old man.
The most frequent angiographic abnormalities are segmental constriction with poststenotic
Doppler ultrasound will show a focal area of color aliasing with velocities >2 m/sec, a velocity gradient between the stenotic and prestenotic segment of more than 2:1, and poststenotic
spectral broadening (Figure 13A).
A CT angiogram was done after the initial operation that showed a suspected stenosis at the origin of the celiac artery with mild poststenotic
6,24) The effect is multifactorial and includes a decrease in central sympathetic outflow, dilation of poststenotic
coronary arteries and a decrease in peripheral norepinephrine release.
An angiogram was performed which revealed mild stenosis of the left ICA at the PCOM junction with poststenotic
dilation and moderate stenosis of the right ICA at the PCOM junction with both poststenotic
dilation and irregular dilation of the right vertebral artery just distal to the posterior inferior cerebellar artery.
An asymptomatic patient with cervical or first rib arterial compression producing poststenotic
dilatation of the axillary subclavian artery should undergo rib resection, preferably using the transaxillary approach, removing the ribs, both first and cervical, without resecting the artery.
The posteroanterior film shows poststenotic
dilatation of the aorta and left ventricular prominence.
HCU: In medical school, I learned about the vascular injuries and poststenotic
aneurysms of the artery distal to the cervical rib and TOS, as well as the Paget-Schroetter syndrome (PSS) (effort thrombosis of the axillary subclavian vein).
Because of the focal narrowing of the thoracic aorta distal to the left subclavian artery and the pre- and poststenotic
dilatation of the aortic knob and aortic isthmus, the left-sided mediastinal border on the posteroanterior chest radiograph can resemble the number 3 to an experienced observer (Figure 1).
