  • Title: Comparison of computed tomography and digital subtraction angiography of preoperative evaluation of soft-tissue tumors of the limbs.
    Author: Crone-Münzebrock W, Baake S, Thoma G, Müller P, Rehder U.
    Journal: Arch Orthop Trauma Surg (1978); 1985; 104(5):319-24. PubMed ID: 3911921.
    Abstract:
    The preoperative results of computed tomography (CT) (n = 59) and digital subtraction angiography (DSA) (n = 14) were compared with the intraoperative site and the pathological histological finding. The tumor was correctly estimated by CT in 69% (difference less than 20%), and overestimated in 31% (difference greater than 20%). The superiority of CT consisted in the visualization of intratumor alterations and the representation of the muscle compartments concerned and of the spatial relationship of the tumor to the bone and large vessels. Specific morphological CT criteria were found only in rhabdomyosarcoma and liposarcoma. Unequivocial preoperative appraisals with regard to the histological finding to be expected were possible only in the case of lipoma. DSA was helpful for evaluation of vascular involvement and vascularization. The technique contributed to differential diagnosis (malignant-benign) in only 70%. In peripheral soft-tissue tumors (lower leg, forearm), arterial DSA is preferable to venous DSA. Angiography should be employed after the CT investigation and reserved for specific cases.
