Massive Pulmonary Embolism due to Inferior Vena Cava Thrombosis Related to Compression by Lumbar Artery Pseudoaneurysm. A Case Report and Review of Literature.

Lumbar artery pseudoaneurysm (LAPA) is a pathology infrequently described in the literature. The most frequent complications are the expansion and rupture of the pseudoaneurysm. Reports of association between PE with LAPA have not yet been described. We present a 53-year-old male patient with LAPA whose expansion caused compression of the inferior vena cava and subsequently PE. He underwent mechanical thrombectomy and inferior cava vein filter placement associated with embolization of the LAPA. Despite the severe clinical profile, the patient was discharged with a favorable postoperative course without complications. This case report also includes a review of the literature.

Uso de anhidrido carbónico como medio de contraste en la arteriografía y en ultrasonido intravascular en el implante endovascular de prótesis en aneurisma de aorta abdominal en paciente con insuficiencia renal: Reporte de caso / Use of carbon dioxide as a contrast medium for arteriography and intravascular ultrasound in endovascular prothesis of an abdominal aneurism in a patient with renal insufficiency: A case report

El EVAR (endovascular aortic replacement) es una técnica mínimamente invasiva para el tratamiento de los aneurismas de aorta abdominal (AAA). A pesar de ser una técnica muy útil en pacientes complicados, se ve restringida en pacientes con enfermedad renal crónica avanzada (ERCA) y en alérgicos a los medios de contraste yodados usados para el procedimiento. El objetivo del reporte fue describir el uso seguro y eficaz de la arteriografía con CO combinada con IVUS (intravascular ultrasound) en el implante de prótesis endovasculares para AAA en un paciente con ERCA y alérgico a los contrastes yodados. Se realizó la recopilación de datos de historia clínica para la descripción del procedimiento y resultados postoperatorios. El uso de la arteriografía con CO y el IVUS en el EVAR constituye una alternativa útil en pacientes que presentan AAA con ERCA y alérgicos al contraste yodado, con resultado post operatorio adecuado.

The endovascular aortic replacement (EAR) is a minimally invasive technique for the treatment of abdominal aortic aneurisms. Despite of being a very useful technique it is restricted in patients with advanced chronic kidney disease and in patients allergic to iodine based contrast. The objective of this report is to describe the safe and effective use of arteriography using carbon dioxide combined to intravascular ultrasound in the endovascular aortic replacement of an aortic aneurism in a patient with renal insufficiency and history of allergy to iodine based contrasts. A review of the clinical chart of a patient who underwent this procedure was performed.
