Area of Science:

  • Vascular Surgery
  • Emergency Medicine

Background:

  • Acute aortic occlusion (AAO) is a critical vascular condition with significant morbidity and mortality.
  • Prompt recognition and management are essential for patient outcomes.

Purpose of the Study:

  • To evaluate the clinical characteristics, management, and outcomes of patients with acute aortic occlusion.
  • To highlight the importance of early diagnosis and intervention in improving survival rates.

Main Methods:

  • A prospective study of 11 patients admitted with acute aortic occlusion over 12 months.
  • Data collected included patient demographics, underlying medical conditions, clinical presentation, and treatment modalities.
  • Outcomes, including mortality and survival, were analyzed.

Main Results:

  • The study included 11 patients, predominantly male (10), with a median age of 58. Hypertension was the most common comorbidity.
  • All patients presented with painful lower limb paraparesis/paraplegia and absent pulses.
  • The overall mortality rate was high at 82% (9/11), with survivors undergoing vascular reconstructive surgery.

Conclusions:

  • Acute aortic occlusion is a rare but catastrophic vascular event with a high mortality rate.
  • Clinicians must maintain a high index of suspicion for AAO in patients with suggestive symptoms.
  • Early diagnosis, mandatory peripheral pulse examination, and prompt treatment are vital for improving patient outcomes.
