Reference Diameters of the Abdominal Aorta and Iliac Arteries in the Korean Population

PURPOSE: It is important to know the normal diameter of artery throughout the body so that clinicians are able to determine when an artery becomes aneurysmal. However, there are no previous studies on the normal diameter of arteries in the general Korean population. The purpose of this article is to determine the normal reference diameters of the abdominal aorta and iliac arteries in the Korean population. MATERIALS AND METHODS: We recruited the study population from three cities in Korea for the abdominal aortic aneurysm (AAA) screening. We measured the diameter of the aorta and iliac arteries. We analyzed the reference diameter of the population without AAA. The results were analyzed by Student's t-test and ANOVA on SPSS version 19. A p value <0.05 was considered to be statistically significant. RESULTS: One thousand two hundred and twenty-nine people were enrolled. 478 men and 751 women, with a mean age of 63.9+/-10.1 years (range 50 to 91) were examined. Eleven out of 1229 (0.89%) were diagnosed with AAA. In the population of 1218 people without AAA, the mean diameters (cm) of male/female were 2.20/2.11 (p<0.001) at suprarenal, 2.04/1.90 (p<0.001) at renal, 1.90/1.79 (p<0.001) at infrarenal, 1.22/1.17 (p<0.001) at right iliac and 1.47/1.15 (p=0.097) at the left iliac, respectively. There was a significantly larger diameter in the male population. The diameter of each level increased with age. CONCLUSION: The normal reference diameter of the infrarenal abdominal aorta in the Korean population is 1.9 cm in males and 1.79 cm in females. The diameter of the abdominal aorta increases with age.

Revascularización endovascular de la enfermedad oclusiva ateroesclerótica crónica de la aorta infrarrenal: reporte de tres casos clínicos / Endovascular revascularization of infrarenal aortic chronic atherosclerotic disease: a report of three clinical cases

La revascularización endovascular de la aorta infrarrenal en pacientes sintomáticos con lesiones oclusivas ateroescleróticas crónicas surge como modalidad terapéutica en casos seleccionados, idealmente en lesiones tipo A y B. Comunicar los resultados inmediatos y el seguimiento a largo plazo, de pacientes con clínica de claudicación intermitente de miembros inferiores, diagnosticados con estenosis significativa de la aorta infrarrenal entre junio de 2002 y enero de 2008. Tres pacientes fueron sometidos a angioplastía percutánea de la aorta infrarrenal. con implante de stent o stent-graft, indicándose al egreso aspirina, clopidogrel y cilostazol, así como rehabilitación. Se realizó seguimiento clínico y por angiotomografía al año. El promedio de estenosis fue de 86,3%, 0% posangioplastia. Durante el seguimiento se evidenció mejoría clínica y ausencia de reestenosis. La angioplastia con balón e implantación de stent ha demostrado ser una técnica segura y efectiva como lo describe la literatura actualmente. Siendo una modalidad de menor costo para pacientes con esta entidad clínica.

Endovascular revascularization of chronic atherosclerotic type A and B lesions of the infrarenal aorta is a therapeutic option in selecte symptomatic patients. Communicate immediate and long-term follow-up autcome of patients with lower limb intermittent claudication with significant infrarenal aortic stenosis diagnosis between June 2002 and January 2008. Three patients underwent percutaneous transluminal angioplasty of the infrarenal aorta with either stent or stent-graft deployment, treated ofter discharge with aspirin, clopidogret and rehabilitation. One year clinical and tomographic follow up was made. Stenosis average was 86.3%, 0% after angioplasty. Clinical improvement and no restenosis were evident during follow-up. Percutaneous transluminal angioplasty with stent deployment seems to be a safe an effective approach to treat these lesions as reported in the literature, at a lower cost on an outpatient basis.
