A surgical suture, also known as a stitch or stitches, is a medical device used to hold body tissues together and approximate wound edges after an injury or surgery. Application generally involves using a needle with an attached length of thread. There are numerous types of suture which differ by needle shape and size as well as thread material ...
After harvesting, the pericardium—the sac that surrounds the heart—is opened and stay sutures are placed to keep it open. Purse string sutures are placed in the aorta to prepare the insertions of the cannula into the aorta, and a catheter which temporarily arrests the heart using a solution high in potassium. Another purse string is placed ...
The surgeon closely examines the surface of the heart and chooses and marks an insertion site near the apex. A ring of sutures reinforced with pledgets is installed around the insertion site. The free ends of the sutures are looped through a sewing ring on the left ventricle connector.
Crocodilian form of crurotarsal ankle. The astragalus (pink) is fixed to the tibia (green) by a suture. Adapted with permission from Palaeos. In the type of crurotarsal ankle, which is found in crocodilians and some other archosaurs, the astragalus is fixed to the tibia by a suture, and the joint bends around a peg on the astragalus, which fits into a socket in the calcaneum.
As a result, the suture is placed deeply within the septum, and the new neck of the suture, which holds the Dacron patch, extends from the septum. Dor explicates this procedure in detail. When the lesion is placed on the posterolateral wall of the heart, a triangular patch is used and stabilized by the posterior mitral annulus. This placement ...
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
Suture techniques include horizontal pledgeted mattress sutures, and running polypropylene suture. Critical attention is necessary to avoid injury to the conduction system located on the left ventricular side of the interventricular septum near the papillary muscle of the conus. Care is taken to avoid injury to the aortic valve with sutures.
Surgical staples are specialized staples used in surgery in place of sutures to close skin wounds or to resect and/or connect parts of an organ (e.g. bowels, stomach or lungs). The use of staples over sutures reduces the local inflammatory response, width of the wound, and time it takes to close a defect. [1]
