AIM: The purpose of this study was to evaluate the usefulness of gadolinium enhanced 3D magnetic resonance (MR) angiography (CE MRA) as an alternative to translumbar or brachial angiography in the pre-operative work-up of patients with aortoiliac occlusion. MATERIALS AND METHODS: Nineteen patients (14 men and five women; age range 45–77 years; mean 62 years), not suitable for perfemoral angiography (aortoiliac occlusion, n = 18; infected femoro-femoral graft with femoral artery pseudoaneurysm, n = 1), underwent pre-operative CE MRA and catheter angiography (translumbar, n = 5; brachial, n = 14). CE MRA was performed using a 3D fast spoiled gradient-recalled pulse sequence during the intravenous injection of 40 ml of gadolinium DTPA and a 32-s breath-hold. All patients subsequently underwent surgical ( n = 13) or percutaneous transluminal ( n = 6) treatment for their vascular disease. The accuracy of CE MRA was determined compared with the findings at catheter angiography taken as the gold standard. RESULTS: CE MRA gave accurate information about the occlusion, inflow and distal run-off in the majority of patients. CE MRA revealed occlusions with an accuracy of 94.7% in the aortic segment, 98.7% in the iliac segment, and 100% in the common femoral segment. The arterial segments distal to the common femoral artery were not completely visualized in four patients but CE MRA provided sufficient information to plan either surgical or percutaneous transluminal therapy in all but one patient. CONCLUSION: CE MRA is highly accurate in showing the presence and extent of aortoiliac occlusions. In our study group, CE MRA gave sufficient information in the pre-operative evaluation of aortoiliac occlusion. Torreggiani, W. F. et al . (2002). Clinical Radiology 57 , 625–631.

Splenic artery aneurysms are the most common visceral aneurysm. They are treated by surgical or endovascular techniques and more recently by embolization. This short report describes the use of trans-catheter thrombin embolization to treat a very large volume splenic artery aneurysm.

A testicular varicocele represents an abnormal degree of venous dilatation of the pampiniform plexus. It is a relatively common condition and may present at scrotal pain and swelling. An association with male subfertility is an area of debate. This article describes the present day radiological criteria and imaging techniques to aid accurate diagnosis of varicoceles. In addition, the role of the interventional radiologist in treating this condition is discussed.
