What does RIMA mean in UNCLASSIFIED
RIMA stands for Right Internal Mammary Artery. It is an abbreviation used to describe a large artery located in the chest that supplies oxygenated blood to the chest wall and surrounding structures. The Right Internal Mammary Artery (RIMA) is one of two arteries that are typically harvested during Coronary Artery Bypass Grafting (CABG). This procedure involves using a portion of the RIMA or another artery, such as the Left Internal Mammary Artery (LIMA), to create a bypass around a blocked coronary artery so that adequate levels of oxygen-rich blood can reach areas of the heart that are not being properly supplied.

Definition
Simply put, RIMA stands for Right Internal Mammary Artery which is a large artery located in the chest area of humans and other animals. It supplies oxygenated blood to tissues in order to provide them with essential nutrients and energy needed by them in order to perform their regular processes. The most common use of this term is in medical procedures when it comes to treating cardiovascular diseases.
Purposes
The main purpose of harvesting RIMA for cardiac vascular surgeries is mainly due its location, size, robustness, length, and course. Unlike other vessels in the body, such as those used in hemodialysis accesses for end-stage renal disease patients or peripheral arterial bypass grafts, RIMA undergoes little anatomical reshaping and can be accessed relatively quickly by surgeons while having minimal impact on adjacent structures or organs. As such, surgeons use it often during Cardiac Interventional Procedures (CIPs) when revascularization techniques are needed such as CABG surgeries or Percutaneous Transluminal Coronary Angioplasty (PTCAs).
Advantages
One advantage provided by using RIMA for CIPs is increased graft patency rate over alternative methods; studies have shown 5-year graft patency rates improved from 66% with saphenous vein grafts up to 89% with RIMA grafts alone. Additionally, harvesting from the RIMA seeks to minimize risk associated with more invasive measures like vein harvests elsewhere on the body where extensive manipulation may lead to greater risks for injury post-procedure.
Essential Questions and Answers on Right Internal Mammary Artery in "MISCELLANEOUS»UNFILED"
What is the RIMA?
The Right Internal Mammary Artery (RIMA) is a coronary artery located on the right side of the chest. It typically supplies the lower third of the heart’s left ventricle with oxygenated blood.
What are the benefits of using RIMA in surgery?
Using the RIMA for cardiovascular surgical procedures can reduce long-term mortality and improve outcomes for patients. The artery's location makes it less likely to be damaged by scar tissue that forms around other major vessels, and it offers superior graft patency compared to other vessels. Additionally, studies have indicated that using a patient's own internal mammary arteries minimizes exposure to foreign materials during vascular reconstruction.
How is RIMA accessed during surgery?
During surgery, medical professionals access the Right Internal Mammary Artery through a small incision made in either the right or left side of the patient's sternum or rib cage. A thin wire is then inserted into a tiny puncture hole in order to gain access to the artery before any additional instruments are inserted.
Is it common for both right and left IMA (Internal Mammary Arteries) to be used during surgery?
Yes, it is common for both right and left Internal Mammary Arteries (IMAs) to be used during coronary bypass surgery - one from each side of the chest cavity. This helps ensure that an adequate blood supply is established between both sides of the heart.
Why might there be complications when using RIMA in cardiac surgery?
Although complications associated with using RIMA in cardiac procedures are relatively rare, they do occur from time to time. This could include bleeding at the suture line or site of insertion, infection at or near site of insertion, or kinking/occlusion of graft vessel due to improper placement.
Are there any risks associated with accessing RIMA?
Although accessing RIMA does not carry as much risk as some other types of cardiac surgeries, there are still risks associated with accessing this area - including inadvertent damage to adjacent veins or other structures inside your chest cavity. As such, these procedures should always be conducted by experienced medical professionals who understand how to properly access this area without causing further injury.
Final Words:
In conclusion, RIMA stands for Right Internal Mammary Artery which is used in cardiac treatment procedures because it has fewer risks than alternative measures and provides increased graft patency rates over time when compared against saphenous vein grafts. Knowing what this abbreviation means can help patients better understand their treatments before consenting or undergoing any surgical procedure pertaining to cardiovascular health problems.
