Acute aortic occlusion (AAO) is a serious vascular emergency. Embolism is the main cause, and while survivors have a good long-term outlook, permanent anticoagulation is recommended for embolic cases.

Area of Science:

  • Vascular Surgery
  • Cardiovascular Medicine
  • Emergency Medicine

Background:

  • Acute aortic occlusion (AAO) is a critical vascular condition requiring prompt diagnosis and management.
  • Understanding the causes, risk factors, and outcomes of AAO is crucial for improving patient care.

Purpose of the Study:

  • To define the causes, clinical presentation, treatment, prognostic variables, and outcomes of acute aortic occlusion.
  • To analyze a large patient cohort over a significant period to identify trends and improve understanding of AAO.

Main Methods:

  • Retrospective review of 46 adult patients diagnosed with acute aortic occlusion over 40 years.
  • Data collected included arteriographic/operative confirmation, clinical presentation, treatment (operative/nonoperative), and outcomes (mortality, morbidity, survival).

Main Results:

  • Embolism (65%) and thrombosis (35%) were the primary causes of AAO.
  • Risk factors included heart disease/female gender for embolism, and smoking/diabetes for thrombosis. Ischemia severity predicted outcome better than duration.
  • Hospital mortality was 35%, morbidity 74%. Recurrent embolism occurred in 43% of embolic AAO patients. 5-year survival for survivors was 72%.

Conclusions:

  • AAO is a severe vascular emergency with high morbidity and mortality, despite appropriate treatment.
  • Survivors of AAO experience a reasonable long-term prognosis.
  • Permanent anticoagulation is recommended for embolic AAO to reduce recurrent embolism rates.
