Anatomic variations of the branches of the aortic arch in a Peruvian population

Abstract

Aortic Arch Type I, Type II and Type IX were the most frequent variations in this Peruvian study. Additionally, we also found two more new types that have not been previously described in the literature. Further investigation regarding these variations is needed in order to assess a racial factor in South America and possible relationships with clinical or surgical events.

Effectiveness of a handmade “New Carotid Catheter” in transradial carotid angiography: A comparison with conventional multipurpose catheters

“…In Type IV aortic arches (3%), which also include arteria lusoria, the right subclavian artery stems from the aorta near the descending aorta after the carotid arteries. [29][30][31] (Figure 7).…”

“…Factors that increase the risk of RAO are prolonged cannulation and small diameter of the radial artery. 23,29,37 Tortuosity is one of the most important issues negatively impacting transradial angiography success. The incidence and severity of tortuosity increase with age.…”

“…In Type III aortic arches (2%), the right and left common carotid arteries directly originate from the aortic arch as a one unit or separately. In Type IV aortic arches (3%), which also include arteria lusoria, the right subclavian artery stems from the aorta near the descending aorta after the carotid arteries . (Figure ).…”

“…RAO is frequently clinically silent due to the dual blood supply to the hand and is thus often overlooked. Factors that increase the risk of RAO are prolonged cannulation and small diameter of the radial artery …”

‘New Developed Femoral-S Carotid Catheter’ is Very Effective and Safe in Carotid Angiography: A Retrospective Study

“…Type 4 is including arteria lusoria, the right subclavian artery is removed from the aorta after the carotid arteries. This type of aorta is seen in 3% of the population [9][10][11].…”
