Introduction
|
|---|
An 18-year-old
cyclist was referred to the laboratory for unexplained
pain in his left
lower limb during exercise. He had started
competition at 14 years of
age and had cycled

10 000 km/y in
the preceding 5 years.
He had complained
for 18 months of a
subjective sensation of a painful and swollen left
thigh at
maximal exercise. Different physiotherapies and treatments
proved
unsuccessful. Clinical investigation and ankle-to-brachial
indices
at rest were normal (1.10 on the left side and 1.15 on the
right
side). An incremental (50 W/3 min) bicycle exercise test was
stopped
at 330 W because of pain. Ankle-to-brachial pressure
measurements
showed a fall of left-side values <0.5. Ultrasound
imaging
showed typical lesions of endofibrosis, consisting of a
mildly
echoic thickening of the left myointimal border (normally

0.3
mm) in an axial view of the iliac arteries (Figure 1

). On arteriography
(Figure 2

), the stenosis was evident only
when the arterial
diameter of the proximal left iliac
artery was compared with
the contralateral iliac artery or the femoral
segment. Surgery
consisted of shortening the artery, resection of the
fibrotic
lesions, and enlargement of the artery with a saphenous vein
patch.
Figure 3

shows the
histological findings of severe stenosis
(

75%
of the vessel lumen) on cross section of the artery. Three
years
after surgery, the patient is asymptomatic during
exercise.
