“…However, Cagnie et al [2] had earlier found that no correlation between differences in VA diameter and hand dominance existed, thus there is no significant connection between VAD and hand preference. As we noted previously [27], the embryologic origin of the present variation (LVA arising aortic arch) arises when the anastomosis between the 6 th and 7 th intersegmental arteries does not develop on the left side. In this scenario, the 6 th intersegmental artery remains, leading to the LVA arising from the aortic arch between the left common carotid and subclavian arteries.…”

Background: The aim of the study was to probe the morphological features of the proximal segment (V1) of vertebral artery (VA) in a sample of Chinese cadavers. Materials and methods: The origin, course and outer diameter at origin of the pre-vertebral part of the VAs were evaluated in 119 adult cadavers. Results: It was found that 94.12% of the VAs originated from the subclavian arteries, bilaterally. The variant origins were present in 5.88% of the cadavers and all originated directly from the arch of the aorta. All the variations were observed on the left side of male cadavers. The average outer diameters at origin of the normal and variation groups were 4.35 ± 1.00 mm and 4.82 ± ± 1.42 mm, respectively, p = 0.035. In the normal group, but not in the variation group, the average diameter in the males was significantly larger than that in the females (4.50 ± 0.99 mm, 3.92 ± 0.92 mm, respectively, p = 0.000). In addition, only 5 cadavers in the normal group had hypoplastic VAs (4.20%, 4 males,. Vertebral artery dominance (VAD) was present in 91 (69 males) out of 112 cadavers and more common on the left (n = 48). In addition, 3 cadavers satisfied conditions for coexistence of VAD and vertebral artery hypoplasia. All 7 cadavers in the variation group exhibited VAD, which was more common on the right side (n = 5). Conclusions: The morphologic variations and frequencies described above have implications for the early prevention, abnormal anatomy detection, accurate diagnosis, safe surgery and endovascular treatment of cardiovascular and neurological disease.

“…Much literature has reported the incidence of variations of aortic arch from 13.3% to 26% [Natsis 2009]. Although the occurrence of aortic branch variability is rare, there are a few of these variabilities that may directly lead to clinical misdiagnosis or surgical failure [Qiu 2019]. Therefore, it is imperative to summarize the treatment experience of AD patients with aortic arch variation.…”

Aortic dissection (AD) is a life-threatening disease, and endovascular repair by stent graft is an effective treatment. Surgery often fails for a variety of reasons, such as aortic arch variation. We present the case of a 27-year-old female with aortic dissection with a rare anatomical aortic arch variation caused by chest trauma. This patient recovered well after endovascular repair. This case report demonstrates endovascular repair can be applied to aortic dissection patients with rare anatomical aortic arch variation.

“…The presence of congenital anomalies of the aortic arch in AAD patients could not be ignored (65,66), and special cerebral perfusion strategies need to be considered based on different situations.…”

This review highlights vital details that can be easily overlooked and discuss how to identify and fix failed cannulation from another novel insight. Appropriate arterial cannulation strategy during cardiopulmonary bypass (CPB) in Stanford type A aortic dissection (AAD) is highly necessary to reach satisfactory perfusion effects and appreciable clinical outcomes. Despite several previously published reviews on cannulation strategies in AAD, most focus on the advantages and disadvantages by comparing various cannulation strategies. In fact, most of evidence came from retrospective studies. More importantly, however, some important details and novel approaches maybe overlooked due to variety reasons. These overlooked details also make sense in clinical practice. Papers related to cannulation refer to type AAD were retrieved and analyzed from the PubMed and Medline database. The key words such as "aortic dissection", "cannula", "cannulation", "cannulation strategy", "cerebral perfusion", "type I aortic dissection" were conducted and analyzed. In addition, we looked at some new and very significant specific perfusion techniques such as anterograde cerebral perfusion combined with retrograde inferior vena caval perfusion (RIVP) and reperfusion via the right carotid artery before surgery. The arterial cannulation site and strategy should be determined individually. Monitoring measures are very necessary in the whole procedure.
