The purpose of this study was to investigate the clinical usefulness of combined
whole body blood pool scintigraphy (WBBPS) and lymphscintigraphy (LS) in the
characterization of patients with congenital vascular malformations (CVMs) of the
extremities. Subjects included 134 patients who underwent Tc-99m RBC WBBPS and
Tc-99m filtered tin colloid (or antimony sulfur colloid) LS on initial diagnosis.
Scintigraphic results were interpreted as arteriovenous malformations (AVMs),
venolymphatic malformations (VLMs), lymphatic malformations (LMs), and venous
malformations (VMs). Final diagnosis of the type of vascular malformation was
determined by physical examination, magnetic resonance imaging (MRI),
angiography, duplex ultrasonography, and/or biopsy results. The final diagnosis
demonstrated that 14 of the study subjects had an AVM, 29 had a HLM, 20 had a LM,
and 71 had a VM. The sensitivity of WBBPS and LS in the characterization of CVM
was 85.7% (12/14) for AVMs, 96.6% (28/29) for VLMs, 95.0% (19/20) for LMs, and
88.7% (63/71) for VMs. The specificity was 100% for AVMs (120/120), 91.4% for
VLMs (96/105), 99.1% for LMs (113/114), and 98.4% for VMs (62/63). The overall
accuracy of WBBPS and LS was 91.0% (122/134). Our results show that combination
of WBBPS with LS can characterize extremity CVMs in patients with high diagnostic
accuracy, and may thus be useful for making optimal treatment decisions.
