Insights

Segmental arterial mediolysis (SAM) can cause rapidly growing abdominal pseudoaneurysms. Prompt diagnosis and urgent endovascular intervention, like coil embolisation, are crucial for managing ruptured pseudoaneurysms in SAM.

Area of Science:

  • Vascular Surgery
  • Interventional Radiology
  • Medical Imaging

Background:

  • Segmental arterial mediolysis (SAM) is a rare arteriopathy.
  • SAM can lead to the formation of abdominal pseudoaneurysms.
  • Pseudoaneurysms pose a significant risk of rupture and hemorrhage.

Purpose of the Study:

  • To highlight the rapid progression of abdominal pseudoaneurysms in a patient with SAM.
  • To emphasize the importance of timely diagnosis and intervention in managing SAM-related pseudoaneurysms.
  • To showcase the successful use of endovascular techniques for treating ruptured pseudoaneurysms.

Main Methods:

  • Case report of a 62-year-old male patient with SAM.
  • Diagnostic angiography to identify pseudoaneurysms.
  • Successful endovascular coil embolisation for ruptured pseudoaneurysms.

Main Results:

  • The patient presented with rapidly developing abdominal pseudoaneurysms.
  • Rupture of the pseudoaneurysms necessitated urgent intervention.
  • Successful coil embolisation achieved hemostasis and resolved the pseudoaneurysms.

Conclusions:

  • Abdominal pseudoaneurysms in SAM can progress rapidly.
  • Early diagnosis and prompt endovascular intervention are vital for favorable outcomes.
  • Coil embolisation is an effective treatment for ruptured pseudoaneurysms in SAM.

Aneurysm 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...

Aneurysm 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...

Aneurysm 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...

Abdominal Aorta01:25

Abdominal Aorta

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.
The celiac trunk, a singular artery, divides into the left gastric artery, which...

Peripheral Artery Disease I: Introduction

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...
