Summary
Partial sternotomy offers a viable approach for total arch replacement in select cardiac surgery patients. Early outcomes show satisfactory results with no mortality or neurological complications, suggesting its potential as a beneficial surgical option.
Area of Science:
- Cardiovascular Surgery
- Thoracic Surgery
- Minimally Invasive Cardiac Surgery
Background:
- Partial sternotomy is an established technique for cardiac procedures.
- Its application for total arch replacement (TAR) in selected cases has been explored since 2013.
Purpose of the Study:
- To evaluate the early clinical outcomes of total arch replacement performed via partial sternotomy.
- To assess the feasibility and safety of this minimally invasive approach for complex aortic surgery.
Main Methods:
- Retrospective review of 15 patients undergoing total arch replacement using partial sternotomy between July 2013 and December 2015.
- Procedures were conducted under hypothermic circulatory arrest with selective cerebral perfusion.
Main Results:
- Median skin incision length was 9 cm, with various sternotomy configurations (L-shape, T-shape).
- Zero 30-day and in-hospital mortality, with no neurological complications.
- Median ICU and hospital stays were 3 and 18 days, respectively. Two patients required reoperation for graft-induced hemolytic anemia; no aorta-related deaths occurred during follow-up.
Conclusions:
- Total arch replacement via partial sternotomy demonstrates satisfactory early results in selected patients.
- Partial sternotomy is a promising alternative for total arch replacement, offering potential benefits in minimally invasive cardiac surgery.

01:10The 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.

A partial fraction is a component of a rational expression represented as the sum of simpler fractions. When a rational function is expressed as a ratio of two polynomials, it can often be decomposed into a sum of fractions whose denominators are simpler polynomials, typically linear or irreducible quadratic factors. This process is called partial fraction decomposition, and it is used to simplify complex expressions for integration, solving equations, or analysis.Partial fraction decomposition...

03:03Mixtures of Gases: Dalton's Law of Partial Pressures and Mole Fractions
44.3K
Unless individual gases chemically react with each other, the individual gases in a mixture of gases do not affect each other’s pressure. Each gas in a mixture exerts the same pressure that it would exert if it were present alone in the container. The pressure exerted by each individual gas in a mixture is called its partial pressure.

1.1K
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

01:11Dalton's Law of Partial Pressure
2.6K
The partial pressure of a gas is a measure of the thermodynamic activity of the gas's molecules. The pressure that a gas would create if it occupied the total volume available is called the gas's partial pressure. If two or more gases are mixed together in a container, the molecules move randomly and collide with each other, causing them to reach thermal equilibrium. When the gases have the same temperature, their molecules have the same average kinetic energy. Thus, each gas obeys the...

01:12Total Voids in Concrete

Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement...
