Thoracic Aorta01:15

Thoracic Aorta

409
The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Vascular Access

Background:

  • Thoracic aortic surgery requires reliable arterial inflow for cardiopulmonary bypass.
  • Traditional cannulation sites may have limitations in certain surgical scenarios.

Purpose of the Study:

  • To evaluate the safety and efficacy of direct innominate artery cannulation for arterial inflow during thoracic aorta surgery.
  • To assess outcomes including mortality and neurologic events associated with this technique.

Main Methods:

  • A single-center retrospective study of 208 patients undergoing thoracic aortic surgery from 2010 to 2021.
  • Inclusion of data on in-hospital and remote mortality, and adverse neurologic events.
  • Analysis of specific surgical interventions like hemiarch replacement and ascending aorta/aortic valve replacement.

Main Results:

  • Operative mortality was 5.3%, with 7.7% remote mortality at five years.
  • Neurologic deficits occurred in a subset of patients, with varying severity based on CT scan findings.
  • Direct innominate artery cannulation was utilized in procedures such as hemiarch replacement (50.5%) and ascending aorta/aortic valve replacement (34.1%).

Conclusions:

  • Direct innominate artery cannulation is a safe and effective method for arterial inflow during cardiopulmonary bypass.
  • It provides a reliable alternative to traditional cannulation sites for thoracic aortic surgery.
  • The technique is applicable in both elective and urgent surgical settings.
