The ship was grounded broadside on a steep beach at high tide or, in dockyards, moored at a permanent facility for careening known as a careening wharf. [3] A beach favoured for careening was called a careenage. The vessel was then pulled over with tackles from the mastheads to strong points on the shore while the tide went out.
Vascular surgery is a surgical subspecialty in which vascular diseases involving the arteries, veins, or lymphatic vessels, are managed by medical therapy, minimally-invasive catheter procedures and surgical reconstruction.
Arterial switch operation (ASO) or arterial switch, is an open heart surgical procedure used to correct dextro-transposition of the great arteries (d-TGA). [1] [2]Its development was pioneered by Canadian cardiac surgeon William Mustard and it was named for Brazilian cardiac surgeon Adib Jatene, who was the first to use it successfully.
A surgeon sews the graft to the source and target vessels by hand using surgical suture, creating a surgical anastomosis. Common bypass sites include the heart (coronary artery bypass surgery) to treat coronary artery disease, and the legs, where lower extremity bypass surgery is used to treat peripheral vascular disease.
The harvested blood vessel used in coronary artery bypass graft surgery must be free from damage to ensure proper long-term function and good patient outcomes. [31] Conduit quality is a significant factor in long-term patient results. Conduit quality is not always visibly evident when looking at the exterior of the harvested vessel.
The Great Balance Dock was built of wood planking and timbers. She was 325 feet (99 m) long, 99 feet (30 m) in breadth, and 38.5 feet (11.7 m) in height. The dock contained 12 water-tight compartments, which could be flooded to lower the dock sufficiently for a vessel to enter it, and could be pumped out to lift a vessel free of the water.
Atherectomy is a minimally invasive technique for removing atherosclerosis from blood vessels within the body. It is an alternative to angioplasty for the treatment of peripheral artery disease, but the studies that exist are not adequate to determine whether it is superior to angioplasty. [1]
The Seldinger technique, also known as Seldinger wire technique, is a medical procedure to obtain safe access to blood vessels and other hollow organs. It is named after Sven Ivar Seldinger (1921–1998), a Swedish radiologist who introduced the procedure in 1953.
