A conduit can be used to graft one or more native arteries. In the latter case, an end-to-side anastomosis is performed. In the former, using a sequential anastomosis, a graft can then deliver blood to two or more native vessels of the heart. [21] Also, the proximal part of a conduit can be anastomosed to the side of another conduit.
The term free describes how the graft is completely removed from the donor site rather than remaining attached via a pedicle. The term autogenous , from the Greek root auto- ("self"), describes how the individual who receives the graft is the same individual who provides the donor tissue.
Some perforators can have a mixed septal and intramuscular course before reaching the skin. The name of the particular flap is retrieved from its perforator and not from the underlying muscle. [ 1 ] If there is a potential to harvest multiple perforator flaps from one vessel, the name of each flap is based on its anatomical region or muscle.
Type IV - Leakage through the graft wall due to the quality (porosity) of the graft material. As seen in first-generation grafts, changes in graft material in modern devices have decreased the prevalence of type IV leaks. Type V - Expansion of the aneurysm sac without an identifiable leak. Also called "endotension".
Septal myectomy is a cardiac surgery treatment for hypertrophic cardiomyopathy (HCM). [1] The open-heart surgery entails removing a portion of the septum that is obstructing the flow of blood from the left ventricle to the aorta .
The staggered extension process (also referred to as StEP) is a common technique used in biotechnology and molecular biology to create new, mutated genes with qualities of one or more initial genes. The technique itself is a modified polymerase chain reaction with very short (approximately 10 seconds) cycles. In these cycles the elongation of ...
Crossing the under surface of the sphenoid, the sphenopalatine artery ends on the nasal septum as the posterior septal branches; these anastomose with the ethmoidal arteries and the septal branch of the superior labial; one branch descends in a groove on the vomer to the incisive canal and anastomoses with the descending palatine artery.
Ventricular septal defect (VSD) A hole between the two bottom chambers (ventricles) of the heart. The defect is centered around the most superior aspect of the ventricular septum (the outlet septum), and in the majority of cases is single and large. In some cases, thickening of the septum (septal hypertrophy) can narrow the margins of the ...
