RT Journal Article SR Electronic T1 Clinically Asymptomatic Inferior Vena Cava Obstruction: Case Report JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 15 OP 17 VO 20 IS 1 A1 Moore, Julie E. A1 Chen, David C. P. A1 Moreno, Michie A1 Campofiore, Gail A1 Siegel, Michael E. YR 1992 UL http://tech.snmjournals.org/content/20/1/15.abstract AB We present a case that graphically demonstrates findings of altered venous flow associated with inferior vena cava obstruction. The case illustrates the elaborate modifications to flow which are adopted in an attempt to maintain venous return from the lower extremities. We also present a brief review of altered venous pathways associated with inferior vena cava obstruction.
