Abdominal aortic aneurysm (AAA) repair is a procedure used to treat an aneurysm (abnormal enlargement) of the abdominal aorta. Repair of an abdominal aortic aneurysm may be performed surgically through an open incision or in a minimally-invasive procedure called endovascular aneurysm repair (EVAR). newer procedure is the endovascular aneurysm repair (EVAR): Abdominal aortic aneurysm open repair. Open repair of an abdominal aortic aneurysm involves an incision of the abdomen to directly visualize the aortic aneurysm. The procedure is performed in an operating room under general anesthesia.
Dolphins are carnivores; they eat other animals. Dolphins eat a variety of fish, squid, shrimps, jellyfish and octopuses. The types of fish and other creatures dolphins eat depends on the species of dolphin, where the dolphins live and the wildlife that shares their habitats. There are more than forty species of dolphin and they live in environments ranging from fresh water rivers, estuaries, coastal waters to deep sea open oceans.
Bottlenose dolphins are a very social species, and will often work as a team to maximise their harvest. To hunt larger fish, the bottlenose dolphin will stun the fish by using its tail fluke to throw the fish out of the water and catch the prey in its mouth. Even though bottlenose dolphins have teeth, they do not chew their food. They will swallow small fish whole, or break up larger fish by shaking them, or rubbing the fish on the ocean floor. Bottlenose dolphins can live for up to 50 years. They reach sexual maturity at around 10 years of age, and mate all year round.
