Abstract

BOONRUANGSRI, Porntip; SUWANNAPONG, Bussakorn; RATTANASUWAN, Somsiri  and  IAMSAARD, Sitthichai. Aneurysm, Tortuosity and Kinking of Abdominal Aorta and Iliac Arteries in Thai Cadavers. Int. J. Morphol. [online]. 2015, vol.33, n.1, pp.73-76. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022015000100012.

The prevalence of the aneurysm, tortuosity, and kinking of abdominal aorta and iliac arteries is important for primary consideration in operative planning. The present study was undertaken to investigate the prevalence of abnormality of abdominal aorta and iliac arteries and demonstrate the patterns of kinking external iliac arteries in Thai cadavers. Eighty-five Thai embalmed cadavers (58 males and 27 females) were observed and measured the diameter of abdominal aorta and iliac arteries using a vernier caliper for assessment of aortic aneurysm (AAA). To investigate the tortuosity and kinking of iliac arteries, a standard goniometer was applied to measure the individual angle of iliac artery. In addition, the kinking patterns of external iliac artery were classified. The prevalence of AAA was 4.71% and the aneurysms of common and internal iliac arteries were 4.12 and 0.59%. The tortuosity of common and external iliac arteries were 1.76 and 20%. No tortuosity of internal iliac artery was observed. In addition, the kinking of common, external, and internal iliac arteries were 4.71, 16.47, and 1.18%, respectively. Moreover, the patterns of external iliac aortic kinking were classified into 4 major types (S-shape; reversed ­C shape; low grade shape; and V-shape). We have observed the prevalence of the aneurysm, tortuosity, and kinking of abdominal aorta and iliac arteries in Thai cadavers. Currently, the 4 kinking variations of external iliac arteries were also first demonstrated.
