Imma Case Study

Satisfactory Essays
IMA retractor was used to elevate the sternum to expose the IMA after median sternotomy. Papaverine will be injected into the IMA lumen to prevent vasospasm. Heparin will also be administrated before clamping the IMA with a small bulldog clamp to prevent thrombosis. The IMA can also harvested endoscopically through thoracic ports at the fourth intercostal space. The saphenous vein can be harvested from one or both legs, either endoscopically or openly. The vein will be divided into separate shorter segments according to the number of necessary bypasses, and each segment will be used for bypasses individually. The distal end of the vein will be anastomosed proximately with the aorta in a reversed position so that the semilunar valves …show more content…
A sternal retractor was used and IMA was harvested and clamped with bulldog. The pericardium was continued to incise and pericardial edges was retracted with sutures to enhance exposure of the heart. The surgeon then identified the affected coronary artery, and coronary anastomotic site stabilizer was then used to reduce the movement of the beating heart and isolate the target coronary artery site for anastomosis (Fig.3). A fine mist of humidified CO2 gas was sprayed over the anastomotic site to clear the bleeding. Vessel loops, or silastic shunts was used to control bleeding. The distal anastomosis of the IMA with coronary artery was then performed side to side anastomoses with fine cardiovascular suture. Since IMA remained attached to the subclavian artery, no proximal aortic anastomosis required (Behny, 2006); the blood flow is restored as soon as the IMA anastomosis is established. If saphenous vein free graft was used during the off pump CABG, the distal end of the vein graft will be performed anastomosis first with the coronary artery, and then the other end of the vein graft will be sewn to the aorta either with the sutureless anastomosis device (Calafiore, et al., 2001) or hand sutured to aorta with the help of Hegar dilator loaded with the saphenous vein (Dikmengil, Ozeren, Aytacoglu, & Sucu, 2005) to minimize manipulation of the aorta .

    With the patient in the supine position after adequate prepping and draping of the left supraclavicular infraclavicular areas at 18-gauge needle was inserted in the left subclavian vein. A guide wire was passed through the needle and directed into the right atrium under fluoroscopy. The needle was removed and the incision was made in encompassing the puncture site. The dilator and introducer were passed over the wire. The wire and the dilator were removed and the catheter was threaded through the introducer into the upper portion of the right atrium. Using tunneler than a tunnel was made to a chosen exit site. We had placed a red dot in the general vicinity of the exit site. The catheter was threaded on the tunneler and pulled through the subcutaneous tunnel and out the exit site. The syringe adapters were placed on each tubing and secured with the locking sleeve. Blood could be aspirated and instill through each one easily. Each channel was flushed with heparin solution 100 units per cubic centimeter. A butterfly sleeve was placed on the catheter just distal to the exit site and it was secured to the skin with 2-0 silk sutures. The catheter was secured to the sleeve with a 2-0 silk tie. The course of the catheter was under fluoroscopy showed no evidence of caking. The look also appeared expanded the infraclavicular incision was clothed with interrupted 0 silk suture. Addressing was applied. The patient tolerated the procedure well and was sent to the recovery room in stable condition.…

    Cardiac Catheterization: A cardiac catheterization is performed to obtain information about congenital or acquired heart defects, measure oxygen concentration, determine cardiac output, or assess the status of the heart’s structures and chambers. It may be performed during an angio cardiogram to study the function of the heart or blood supply or to diagnose congenital anomalies or valvular disease. Therapeutic treatments may be done during the catheterization to repair the heart, open valves, or dilate arteries. In this procedure, a long, flexible catheter is passed into the heart through a large blood vessel, usually the femoral or brachial artery. However, with the miniaturization of medical devices, an alternative approach is to use the radial artery (trans radial catheterization). The pressure is measured as the catheter passes through each location, and blood specimens are taken in each area. A dye may also be injected. A team of physicians, nurses, and technicians per-form this procedure, which takes from 1 to 3 hours.…

    Now that we have been miniaturized we can start our journey, we are now in the femoral vein, which is located at the right of the thigh and as we move our way up the vein we will being going past the external iliac, which is formed with the common iliac. The common iliac veins are the vessels that bring the blood to the heart. It has 2 main veins, which are joined together to form the inferior vena cava. The function of this vein is to bring the de-oxygenated blood from the legs as well as the other lower regions of the body to the right atrium. Now that we are at the inferior vena cava let’s see what it has to offer for us. The vena cava are the 2 largest veins in our body” I know crazy huh?!” They carry d-oxygenated blood as well, but form different areas of the body and then to the right atrium of our heart.…

If a second procedure is performed on the same anatomic artery proximal or distal to the index stent, that artery is censored and classified as a success up to the date of the new procedure.

    Coronary artery bypass grafting surgery (CABG) is a type of surgery that improves blood flow to the heart (1). It has been almost introduced sixty years ago in humans when G. Murray (1954) succeeded in performing experimental CABG using the internal mammary artery (IMA). The first reported CABG using the IMA in humans was performed by R. Goetz using the sutureless technique in 1960 (2). The CABG operation has become the most completely studied operation in the history of surgery since the coronary artery diseases have become a major life threatening problem with an overall prevalence of 5.5% in KSA (3).…
