Insights

Skeletonized internal thoracic artery (SKT-ITA) harvesting offers potential benefits in cardiac surgery. This review examines evidence on SKT-ITA effects on graft patency and clinical outcomes compared to traditional pedicle harvesting.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Surgery
  • Thoracic Surgery

Background:

  • The internal thoracic artery is a crucial graft in coronary artery bypass grafting.
  • Traditionally harvested as a pedicle, the skeletonization technique is increasingly adopted.
  • Evidence on the impact of skeletonization on graft quality and patient outcomes requires systematic evaluation.

Purpose of the Study:

  • To systematically review and analyze existing clinical studies on skeletonized internal thoracic artery (SKT-ITA) use.
  • To assess the effects of skeletonization on sternal blood supply, vessel wall integrity, and graft blood flow.
  • To evaluate the impact of SKT-ITA on postoperative graft patency and overall clinical outcomes.

Main Methods:

  • Systematic review of clinical studies reporting on SKT-ITA.
  • Analysis of data concerning sternal perfusion, vessel damage, and blood flow.
  • Evaluation of graft patency rates and clinical outcomes in SKT-ITA versus pedicle grafts.

Main Results:

  • Skeletonization may preserve sternal blood supply and minimize vessel wall trauma.
  • Studies suggest comparable or improved graft patency with SKT-ITA.
  • Clinical outcomes associated with SKT-ITA require further comprehensive analysis.

Conclusions:

  • Skeletonized internal thoracic artery harvesting is a viable alternative to pedicle harvesting.
  • Further research is needed to fully elucidate the long-term benefits and potential risks of SKT-ITA.
  • The technique's impact on sternal healing and graft performance warrants continued investigation.

Thoracic Aorta01:15

Thoracic Aorta

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,...
Veins of Thorax01:19

Veins of Thorax

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.

The Thoracic Cage: Sternum01:17

The Thoracic Cage: Sternum

The thoracic or rib cage forms the body's thorax (chest) portion. Its primary function in the body is to protect vital organs in the thoracic cavity, such as the heart and the lungs. It consists of 12 pairs of ribs with their costal cartilages and the sternum. The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1-T12).
The sternum is the elongated bony structure on the anterior side of the thoracic cage. It consists of three parts: the manubrium, the body, and the xiphoid process.
Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
The Thoracic Cage: Ribs01:20

The Thoracic Cage: Ribs

Ribs are curved, flattened bones forming the thoracic cavity wall with the thoracic muscles. There are 12 pairs of thoracic ribs. The posterior ends of all the ribs articulate with the T1–T12 thoracic vertebrae. In contrast,the anterior ends of most ribs attach to the sternum via their costal cartilages.
Parts of a Typical Rib
A typical rib has a head, neck, and body. The posterior end of the rib is called the head, followed by a narrow neck. The head articulates primarily with the costal facet...
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...
