Resumen
Un saco agrandado de aneurisma ilíaco comprimió la vena ilíaca izquierda, causando una severa hinchazón de la pierna. El stent venoso alivió con éxito los síntomas, lo que demuestra un tratamiento eficaz para esta rara complicación de la reparación endovascular de aneurismas.
Área de la Ciencia:
- Cirugía Vascular
- Radiología Intervencionista
- Medicina Cardiovascular
Sus antecedentes:
- Los aneurismas de la arteria ilíaca pueden crecer después de la reparación endovascular.
- El crecimiento puede provocar compresión extrínseca de las estructuras venosas adyacentes.
- La compresión de la vena ilíaca puede causar edema significativo en las extremidades inferiores.
Objetivo del estudio:
- Informar un caso de compresión de la vena ilíaca izquierda por un saco de aneurisma de la arteria ilíaca en crecimiento.
- Describir el manejo endovascular exitoso de esta compresión venosa.
- Destacar una complicación rara de la reparación endovascular de aneurismas.
Principales métodos:
- Tomografía computarizada (TC) para identificar el agrandamiento del saco del aneurisma de la arteria ilíaca y la compresión de la vena ilíaca izquierda.
- Ultrasonido intravascular (USI) para confirmar la oclusión casi completa de la vena ilíaca izquierda sin trombosis.
- Tratamiento endovascular con un stent venoso (16 × 10 mm) y posdilatación (balón de 16 × 20 mm).
Principales resultados:
- La tomografía computarizada reveló un saco de aneurisma de la arteria ilíaca de 4,8 cm en crecimiento que comprimía la vena ilíaca izquierda.
- El ultrasonido intravascular confirmó la oclusión casi completa de la vena ilíaca izquierda.
- El paciente experimentó alivio de los síntomas a las 24 horas de la colocación del stent venoso.
Conclusiones:
- El agrandamiento de los sacos de aneurisma de la arteria ilíaca puede causar una compresión significativa de la vena ilíaca.
- La colocación de stents endovasculares es un tratamiento eficaz para la compresión venosa secundaria al agrandamiento del saco del aneurisma.
- Este caso subraya la importancia de monitorear el tamaño del saco del aneurisma después de la reparación endovascular.

01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
303
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

370
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...

255
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
364
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

01:30Peripheral Artery Disease I: Introduction
314
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...

01:15Aortic Regurgitation I: Introduction
496
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
