Abstract
Simultaneous kidney and pancreatic transplant is the
criterion standard for treatment of end-stage renal
failure because of diabetic nephropathy. Venous
thrombosis occurs in approximately 5% of pancreatic
transplants, and it is notoriously difficult to treat,
forming the most common nonimmunologic cause
of graft loss. We report a case of early detection of
pancreatic graft venous thrombosis by measuring
urinary amylase, resulting in the successful
endovascular salvage of the pancreatic graft.

Introduction
Pancreatic transplant offers long-term survival for
patients with type 1 diabetes, achieving rates of 85% at
1 year.
1
It is particularly valuable when managing
end-stage renal failure caused by diabetic nephropathy,
combined with a kidney transplant, as there is an
increase in patient survival not matched by kidney
transplant alone.
2,3
However, it is a difficult operation
with appreciable morbidity and mortality, and these
risks increase significantly after a failed pancreatic
transplant.

Thrombosis of the pancreatic graft’s portal vein is
a potentially devastating complication, being
notoriously hard to treat and commonly leading to
graft failure.
1,5,6
Attempts at surgical thrombectomy
are often unsuccessful,
7,8
and so, medical treatment
with systemic anticoagulation is sometimes
recommended, especially for partial thrombosis of the
pancreatic portal vein.

We describe a case of a
pancreatic transplant venous thrombosis that was
diagnosed early and successfully and salvaged by
using interventional radiologic techniques.
Case Report
The patient was a 46-year-old woman with a 25-year
history of type 1 diabetes mellitus. She had end-stage
chronic kidney disease because of diabetic
nephropathy, for which she had been on peritoneal
dialysis and had been experiencing altered
hypoglycemic unawareness. Comorbidities included
diabetic retinopathy, controlled hypothyroidism,
hypertension, hyperlipidemia, and cheiroarthropathy,
which affected several joints. She had been smoking
cigarettes at the time of transplant assessment, but
otherwise had no risk factors for thrombosis, nor any
history of thrombotic disorders. A normal dobutamine
stress echocardiogram was performed 2 years before
the transplant, so a cardiopulmonary exercise test was
arranged after transplant assessment. This test
demonstrated good cardiac reserve with an
anaerobic threshold of 14.9 mL/min/kg and VO
2
heart rate response of 8 mL/beat.
transplant operation
A deceased-donor simultaneous kidney and
pancreatic transplant was performed with the
pancreas being implanted intraperitoneally in the
right iliac fossa, using a donor iliac artery Y graft to
the recipient's right common iliac artery. Venous
drainage was by primary anastomosis from the
donor’s portal vein, to the recipient’s common iliac
vein, with no venous extension graft. Exocrine
drainage was to the bladder. The kidney was
