Retroperitoneal arteriovenous malformation extending through the inferior vena cava into the heart and causing inferior vena cava dissection

Abstract

We present a case of retroperitoneal arteriovenous malformation extending through the inferior vena cava into the heart, which was associated with dissection of the inferior vena cava in a 32-year-old female. Computed tomography and magnetic resonance imaging showed a double-lumen inferior vena cava and a rod-like solid component attached to a sac-like lesion in the right heart chambers. Digital subtraction angiography showed an arteriovenous malformation draining to the inner lumen of the inferior vena cava.

Incidental Detection of Inferior Vena Caval Dissection by Intraoperative High Frequency Vascular Duplex Ultrasonography

“…A contrast‐enhanced CT scan showed the IVC dissection with a double lumen. Another unusual etiology was reported by Sung et al 6 A retroperitoneal arteriovenous malformation (AVM) extending through the IVC into the right heart caused an IVC dissection by cleaving the venous wall. CT and MRI also clearly demonstrated a double‐lumen IVC.…”

“…Previous reports of IVC dissection required the use of contrast CT or MRI. [4][5][6] Venography can identify the site of an intimal tear; however, inaccuracy may arise when the fluoroscopic projection is not in an optimal angle yielding difficult visualization of the intimal flap. Even here, absence of distortion of the lumen, false lumen, and adjoining hematoma will make the diagnosis difficult.…”
