Mr KP is a 43 yrs old Bank manager with high blood pressure
of a few yrs duration.
In Oct 03 he developed severe back pain for which he was
hospitalized and given traction for suspected prolapsed
disc. A few months later he started developing severe cough
for which a chest X-rays was ordered. This revealed a large
shadow on the left side. A CT scan revealed this to be an
aneurysm (swelling) of the descending thoracic aorta. The
aneurysm measured at 7.4 cms in its widest part. The scan
also revealed a tear in the descending aorta which extended
up to the arteries in his legs. This is classified as Debakey
IIIB type of dissection. His blood pressure was controlled
with medication. As his aneurysm continued to increase in
size he was advised surgery or endovascular repair of the
dilated segment.
The advantages and risks of both these procedure were
discussed with the patient and his wife. After much discussion
and thought they elected for an endovascular repair of his
aneurysm.
Further investigation including a repeat CT angio and
a conventional aortogram were performed. This data was sent
to the stent graft manufacturer (Cook Inc), to help them
design and manufacture a stent graft for this patient. It
was ready in 4 weeks.
On 4/8/04 the patient was admitted for this procedure.
The procedure was performed in the cardiac cath lab by Cardiologist
Dr Suresh Vijan, Radiologist Dr Girish Warvedakar and Cardiac
surgeon DR Pawan Kumar. The whole procedure was performed
under local anaesthesia through a cut in the right femoral
artery. A 24 FR stent graft (Zenith, Cook Inc) was positioned
to occlude the tear in the descending aorta, after the origin
of the left subclavian artery. The stent was 130 mm in length.
The stent completely blocked the mouth of the dissection
and excluded the dilated aneurysmal segment, allowing blood
to flow into the descending aorta. Further study revealed
retrograde filling of the abdominal aorta dissection though
the iliac tear. This was closed with the implantation of
two covered stents in the iliac arteries.
The whole procedure was completed in 3 hours, under local
anaesthesia. The patient was transferred to the ICU for
monitoring. He is now fully mobile and walking around in
the hospital. He is expected to be discharged by 9/8/04.
