Summary
Uterine artery pseudoaneurysm, a rare cesarean complication, can cause severe postpartum hemorrhage. This case highlights successful embolization treatment in an asymptomatic patient, emphasizing its importance in differential diagnosis.
Area of Science:
- Vascular Surgery
- Obstetrics & Gynecology
- Interventional Radiology
Background:
- Uterine artery pseudoaneurysm (UAP) is a rare but serious complication following cesarean section (CS).
- Inadequate management of UAP can lead to life-threatening postpartum hemorrhage.
- CS, particularly with extended uterine incisions, may increase the risk of UAP.
Observation:
- A 31-year-old woman presented with an asymptomatic parauterine mass detected via ultrasound 6 days postpartum after CS.
- The mass measured 49 mm with characteristic swirling flow on ultrasound.
- Selective angiography confirmed the diagnosis of uterine artery pseudoaneurysm.
Findings:
- Successful uterine artery embolization was performed to treat the pseudoaneurysm.
- The patient remained asymptomatic throughout the diagnostic and treatment process.
- Review of literature indicates UAP is an important consideration after CS.
Implications:
- Uterine artery pseudoaneurysm should be included in the differential diagnosis for pelvic masses in the postpartum period after CS.
- Early diagnosis and timely intervention, such as embolization, are crucial for managing UAP and preventing hemorrhage.
- This case underscores the importance of vigilant ultrasound and angiography in identifying and treating UAP post-cesarean delivery.

01:30Aneurysm I: Introduction
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...
01:26Aneurysm III: Interprofessional Care
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...
01:21Aneurysm II: Clinical Manifestations and Diagnostic Studies
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...
01:22Aneurysm IV: Nursing Management
Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...
