Computed tomography in the evaluation of a femoral aneurysm

Computerized tomography in the investigation of groin masses following femoral catheterization

Pseudoaneurysm of the femoral artery is an uncommon complication of retrograde arteriography. It is sometimes difficult to clinically differentiate a pseudoaneurysm from a large hematoma. We present 13 cases of suspected femoral pseudoaneurysm following angiography which were investigated by computed tomography (CT). It is suggested that this is a useful procedure in the investigation of groin masses after catheterization.

Computed tomography and magnetic resonance imaging of a superior gluteal artery pseudoaneurysm

The magnetic resonance and computed tomography appearances of a superior gluteal artery pseudoaneurysm are described, with emphasis on the relative advantages and disadvantages of these two imaging procedures.

False aneurysm of the femoral artery: computed tomographic and ultrasound appearances

Twenty-five patients presenting with pulsating masses in the groin, 1-10 days after diagnostic arterial catheterisation, were investigated by computed tomography (CT), ultrasound (US) or both. False aneurysm was demonstrated in 10, four by CT alone, three by US alone and three by both CT and US. Both methods allowed rapid accurate and non-invasive diagnosis of this uncommon complication of arterial catheterisation.

Peripheral aneurysms (p.a.) took only 4% of the 8.461 reconstructive operations in vascular surgery (1966-March 15, 1981). 44% of the p.a. were secondary to arteriosclerosis, while 41% were anastomotic aneurysms. 2/3 of all arteriosclerotic peripheral aneurysms were localized in the iliac or femoral artery; the popliteal artery was involved in 25%. 25% of the patients had 2 and more aneurysms. The popliteal aneurysm was found to be bilateral in 32%. Rupture occurred only in 3.5% whereas 27% of all peripheral aneurysms were associated with distal occlusive disease. In the asymptomatic stage amputation rate was 4%, the operative letality 2%, after complications both increased up to 16%.
