Abstract
The presentation of symptomatic inferior vena cava (IVC) occlusion is variable, and no clear guidance exists on indications for invasive treatment. We describe the first documented case in the literature of IVC occlusion and venous congestion of the spine with associated neurological symptoms, successfully treated with endovascular IVC reconstruction.
Case report
A 31 year-old male presented with a long history of reduced sensation and motor function in his lower limbs upon waking every morning, lasting 30-50 minutes during which he was unable to ambulate. He was involved in a severe road traffic accident as a child, and was born prematurely requiring prolonged neonatal hospitalisation. Both duplex ultrasonography and magnetic resonance venography identified an occlusion of the IVC, with patent common femoral and iliac veins draining into large spinal collaterals. No other cause was identified for his symptoms. After appropriate multidisciplinary team discussion and patient counselling, the patient proceeded to have endovenous recanalization of his IVC and common iliac veins with dedicated venous stents. Post-operatively, the patient reported an immediate resolution of neurological symptoms, with an improvement in quality of life questionnaire scores and with stent patency at 9-month follow up.
Conclusion
IVC occlusion with symptomatic spinal venous congestion is a rare condition which may be successfully treated with endovascular iliocaval recanalization, although long-term outcomes of this treatment are still unknown.
