Background/Aims:
Abdominal aortic calcium (AAC) deposition has been suggested as a marker of early atherosclerosis. There is no published data on the evaluation of AAC in inflammatory bowel disease (IBD).
Methods:
AAC was quantified by computed tomography or enterography scans performed in 98 IBD patients and 1:1 age and sex matched controls. AAC deposition was correlated with IBD characteristics, disease activity or severity parameters, laboratory tests and cardiovascular disease (CVD) risk factors.
Results:
Moderate-severe grade of AAC was found in 35.7% of IBD patients compared to 30.6% of controls (P= 0.544). IBD with CVD and ulcerative colitis patients had significantly higher rates of more severe atherosclerotic lesions (P= 0.001 and P= 0.01, respectively). AAC deposition was similarly distributed in age groups ( < 45, 45–64, and ≥ 65 years) among patients and controls. Multivariate analysis after excluding CVD risk confounders for non-CVD patients found extensive disease (P= 0.019) and lifetime steroids (P= 0.04) as independent risk factors for AAC. Anti-tumor necrosis factor α (TNF-α) use was negatively associated with AAC deposition in non-CVD IBD patients (odds ratio, 0.023; 95% confidence interval, 0.001–0.594; P= 0.023).
Conclusions
More than one-third of IBD patients have moderate to severe AAC. Better control of inflammation with anti-TNF-α agents seems to protect IBD patients from ACC deposition and subsequent atherosclerosis.

Phlegmasia cerulea dolens (PCD) is an uncommon but potentially limb-threatening complication of acute deep vein thrombosis. A 56-year-old male presented with PCD. Color Doppler ultrasonography revealed extensive thrombosis of the left superficial and common femoral and external and common iliac veins. After an unsuccessful iliofemoral thrombectomy, contrast-enhanced computed tomography revealed iliofemoral deep vein thrombosis due to May–Thurner syndrome (MTS). After the deployment of an inferior vena cava filter, the thrombotic occlusion was traversed with a guidewire and direct stenting was performed to achieve immediate recanalization. The patient was discharged two days after the procedure, demonstrating significant clinical improvement. MTS is a rare cause of PCD. Direct iliac vein stenting may be a safe and effective alternative treatment for rapid recanalization if percutaneous mechanical thrombectomy devices are unavailable.
