Aneurysm of the inferior vena cava: case report

Abstract

Venous aneurysms are uncommon. Despite their infrequency, venous aneurysms can present with significant clinical complications such as thrombosis, pulmonary embolism, and death. In this report, we present the case of a thrombosed inferior vena cava aneurysm discovered in a 16-year-old male who had deep vein thrombosis of the right lower extremity. Thrombosis of the inferior vena cava is uncommon in the pediatric population. Therefore, congenital abnormalities such as an inferior vena cava aneurysm should be considered when evaluating pediatric patients who present with deep vein thrombosis.

Inferior Vena Cava Aneurysm in an Infant Presenting With a Renal Mass

“…Trauma or inflammatory processes have also been proposed as inciting factors of acquired aneurysms. 3 Etiology is unknown for most of them, but some authors have suggested an embryological or congenital origin, given their occasional association with other congenital anomalies. 4 In this case, the young age at presentation, absence of previous trauma, or other conditions support this hypothesis.…”

“…It was not possible to establish whether the aneurysm was sacular or fusiform because of the massive bleeding that occurred during surgery. [3][4][5] Although arterial aneurysmal dilatations represent a well-recognized clinical entity, these formations rarely appear in the venous territory. Aneurysms involving the IVC are extremely uncommon with <30 reported cases, and exceptionally described in children.…”

“…[1][2][3][4][5][6][7] To date, their etiology is unknown and some authors have hypothesized that it can be related to a congenital defect. Most cases present as incidental radiologic findings in asymptomatic patients, but can appear as life-threatening massive thrombosis.…”

Nonoperative management of traumatic suprahepatic inferior vena cava pseudoaneurysms

“…8 This approach also allows for thrombolytic therapy in patients presenting with lower extremity swelling and an IVC thrombus. 9 Observation of asymptomatic aneurysms, regardless of location, is an appropriate treatment option and should not be forgotten. In addition to the success of nonoperative management with our patient, Woo et al 10 describe a 5-cm pararenal IVC aneurysm that was successfully treated expectantly with serial CT scans.…”

Inferior vena cava aneurysm presenting as deep vein thrombosis − A case report

“…[7] Thus, for the current case, the definitive management would have been surgical resection of the aneurysm or thrombolysis followed with systemic anticoagulation. [12] Due to unfavorable circumstances of the patient, surgical intervention was deferred and patient was counseled about medical treatment along with proper domiciliary care including physiotherapy. Patient was also informed about thrombotic complications, pulmonary embolism, and sudden death as a consequence of non-operative management.…”
