Background
In this educational exhibit, we present a range of causes, complexity, and management options for abdomino-pelvic venous occlusion.

Educational Goals / Teaching Points
The purposes of this exhibit are to understand the pathophysiology and clinical significance of intra-abdominal venous occlusion; and identify key imaging findings of venous occlusion which vary by imaging modality. Current treatment options are mechanical thrombectomy, thrombolysis, and medical management with anticoagulation. Not all patients may qualify for traditional management options. Recognizing key findings that place the patient at higher risk for complication is an important skill. Novel interventional approaches may be utilized to treat patients for whom conventional treatment options are not feasible.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
A wide spectrum of diseases and clinical scenarios are associated with intra-abdominal venous occlusion. Symptoms may be mild and vague, which can mimic common causes of acute or chronic abdominal pain such as renal colic or even appendicitis. Missed diagnoses may lead to delay in treatment, and can result in morbidity and mortality. Timely recognition of key imaging findings is crucial to guide appropriate medical and interventional management. Available treatment options of venous thrombosis are influenced by factors such as cavernous transformation, variant anatomy, or complications of venous thrombosis. In this educational exhibit, we present a range of causes, complexity and management options for abdomino-pelvic venous occlusion.

Conclusion
Treatment of intra-abdominal venous occlusion is highly dependent on the unique anatomic findings in a given person. Using basic and novel techniques, treatment can be approached to provide high quality care for patients.
