Congenital renal vein aneurysms are a truncular type of venous malformation and are believed to be the outcome of defective development during the later stage of embryogenesis while the venous trunk is being formed. There have been 9 case reports so far. Here, we add the report of a patient who was incidentally detected to have a renal vein aneurysm on computed tomography angiogram. In addition, this is the first description of inferior vena cava thrombosis associated with a thrombosed saccular aneurysm of the renal vein. Case ReportA 29-year old Asian male underwent preemployment medical screening and was detected to have inferior vena cava (IVC) thrombosis on ultrasound abdomen. He was asymptomatic and had no co-morbid illnesses. His physical examination was unremarkable. There was no varicocoele. Basic blood laboratory investigations were all normal. Serum virology markers were negative. His procoagulant workup was negative. Contrast-enhanced computed tomography (CT) abdomen revealed a thrombosed saccular venous aneurysm of size 3.9x3.7 cm arising from the mid-segment of the left renal vein (Figure 1). Retrohepatic IVC was thrombosed; infrahepatic IVC, common iliac and external iliac vein were dilated. Since he was asymptomatic and the renal vein aneurysm was already thrombosed, it was decided to manage him conservatively. At follow up 1-year later, he remains asymptomatic and the aneurysm has maintained the same size. Our radiology colleagues contributed CT angiogram images of another patient with renal vein aneurysm (Figure 2). However, his clinical details could not be retrieved.

To study the prevalence of ASYMPTOMATIC CAROTID ARTERY DISEASE and to identify predictive factors of carotid artery disease, in patients with critical limb ischemia in south Indian patients Materials and methods:-Total of 250 patients with critical limb ischemia admitted in department of vascular surgery, madras medical college, Chennai, underwent carotid duplex scanning by department of radiology, madras medical college, Chennai and a questionnaire was used to collect data concerning known risk factors. Results:-The mean age of the patients was 50±20 years; there were 242 (96.8%) men and 8 (3.2%) women; 72% of the patients had a history of smoking, 10.4% had coronary artery disease, 5.6% had hypertension, 5.6 % had dyslipidemia and 17.2% had diabetes mellitus. Eighteen (7%) patients had carotid artery disease detected by carotid artery duplex scanning of which insignificant Carotid artery disease found in 10 patients, significant carotid artery stenosis in 5 patients and complete occlusion of ICA in 3 patients. Conclusion:-All patients with peripheral vascular disease with large vessel occlusion due to atherosclerosis have to be screened for carotid artery disease.
