Insights

The innominate and subclavian arteries are suitable inflow sites for arterial grafts in myocardial revascularization. Studies show these arteries offer good wall matching and avoid aortic clamping, with all grafts remaining patent.

Area of Science:

  • Cardiovascular Surgery
  • Vascular Grafting
  • Myocardial Revascularization

Background:

  • Identifying optimal inflow sites for arterial grafts is crucial for successful myocardial revascularization.
  • Traditional methods may involve aortic clamping, posing risks in patients with specific aortic conditions.

Purpose of the Study:

  • To evaluate the suitability of the innominate and left subclavian arteries as inflow sites for free arterial grafts.
  • To assess graft patency and patient outcomes when using these alternative inflow sources.

Main Methods:

  • Utilized the innominate artery for radial artery grafts in 4 patients.
  • Employed the left subclavian artery for 3 radial artery grafts and 1 gastroepiploic artery graft.
  • Monitored patient survival and graft patency through restudies.

Main Results:

  • All 8 patients in the study survived.
  • All 5 grafts that were restudied demonstrated complete patency.
  • The innominate and subclavian arteries were found to be suitable inflow sites.

Conclusions:

  • The innominate and left subclavian arteries are viable and safe inflow sites for free arterial grafts in myocardial revascularization.
  • These arteries offer advantages such as better wall matching and avoidance of aortic clamping, especially in atherosclerotic ascending aortas.
  • The use of these vessels supports successful graft patency and positive patient outcomes.

Anastomoses01:19

Anastomoses

In human anatomy, anastomosis refers to a connection or opening between two things, particularly between blood vessels or other tubular structures. The term is derived from the Greek term 'anastomosis,' which means 'outlet' or 'opening.' This natural network of connections plays a critical role in the survival and functionality of the human body.
Anastomoses can be formed at arterial, venous, and lymphatic vessels.
Arterial Anastomosis: These occur between arteries. They are most common in...
The Arch of Aorta01:10

The Arch of Aorta

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...
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...

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
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...
Arteries of Lower Limbs01:20

Arteries of Lower Limbs

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular artery,...
