  • Title: [Imaging of iatrogenic aneurysms and AV fistulas of the lower extremity with IV-DSA and sonography].
    Author: Gross-Fengels W, Beyer D, Lorenz R, Kristen R.
    Journal: Rontgenblatter; 1987 May; 40(5):131-6. PubMed ID: 3299668.
    Abstract:
    Using IV-DSA and ultrasound (real-time), we demonstrated 13 false aneurysms, 2 isolated AV fistulas, 7 aneurysms of profunda patches and 8 aneurysms of bypass grafts. Aneurysms and AV fistulas developed in all 30 patients after different diagnostic and therapeutic procedures. Ultrasound showed partial thromboses of the aneurysms, perivascular changes and compression of the femoral vein, that could not be demonstrated by IV-DSA. On the other hand IV-DSA allowed the recognition of important findings not shown sonographically, such as AV fistulas and stenoses of the proximal and distal arteries. These findings were relevant for further surgical approach. It is therefore concluded that in patients with suspected aneurysm of the femoral or popliteal artery, IV-DSA and ultrasound should be used in conjunction rather than as alternative methods.
