The Aorta01:14

The Aorta

3.0K
The aorta is the largest artery in the human body. It originates from the left ventricle of the heart and extends down to the abdomen, where it splits into two smaller arteries. Structurally, it can be divided into four main parts: the ascending aorta, the aortic arch, the thoracic aorta, and the abdominal aorta.
The average diameter of the aorta is approximately 2-3 cm, but the size can vary depending on the section of the aorta and the individual's age, sex, and body size. The aorta is...

The Arch of Aorta01:10

The Arch of Aorta

1.9K
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Thoracic Aorta01:15

Thoracic Aorta

1.8K
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,...

Abdominal Aorta01:25

Abdominal Aorta

2.5K
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...

Aneurysm I: Introduction01:30

Aneurysm I: Introduction

440
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 IV: Nursing Management

483
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...

Summary

Highly selected octogenarians can safely undergo open aortic surgery. Outcomes, including survival and complications, are comparable to younger patients, challenging the notion that older age is a surgical contraindication.

Area of Science:

  • Cardiovascular Surgery
  • Geriatric Medicine
  • Aortic Aneurysm Research

Background:

  • Older individuals often have comorbidities, making aortic aneurysm surgery a concern.
  • Traditionally, advanced age has been viewed as a contraindication for open aortic surgery.
  • This study investigates surgical outcomes in octogenarians undergoing open aortic repair.

Purpose of the Study:

  • To evaluate the surgical outcomes of selected octogenarians after open aortic surgery.
  • To assess the safety and efficacy of open aortic repair in elderly patients.
  • To determine if advanced age impacts postoperative complications and survival rates.

Main Methods:

  • Retrospective observational study of patients operated on between January 2012 and September 2017.
  • Univariate logistic regression and survival analysis were employed.
  • Kaplan-Meier survival curves were constructed to analyze outcomes.

Main Results:

  • 31 octogenarians (mean age 81.5 years) were analyzed, with a majority male (67.7%).
  • Common procedures included aortic valve replacement with graft interposition (48.4%). In-hospital mortality was 9.4%, with 1-year survival at 77.4%.
  • Older age did not correlate with increased early or late mortality, ICU stay, or total hospital stay.

Conclusions:

  • Highly selected octogenarians experience favorable surgical outcomes after open aortic repair.
  • Postoperative complication rates and survival in this group are comparable to those reported in the general literature.
  • Advanced age alone should not preclude carefully selected elderly patients from undergoing necessary aortic surgery.
