■旋髂深动脉(DCIA)是一条大口径动脉,从髂外动脉(EIA)横向分支,正对着腹壁下动脉(IEA)的起源。据报道,人口变化的起源,长度,和分支模式。这些可能会改变其与明显的手术标志的关系,例如用于术前定位动脉的前上棘(ASIS)和耻骨结节(PT)。从而诱发医源性损伤。尽管如此,肯尼亚的数据很少。
■横断面研究设计。
■为了确定肯尼亚部分人群的深旋髂动脉的解剖结构和骨标志的变化。
■解剖了52具福尔马林固定的成年尸体中的104具DCIA,以暴露DCIA,在此之后,其船只的起源和与ASIS和PT的距离,与腹股沟韧带(IL)的关系,注意到长度和分支模式。计算测量的平均值。所有数据均使用MicrosoftExcel2007(MicrosoftCorporation,雷德蒙德,西澳)。拍摄了船只及其变体的代表性照片。
■发现DCIA在所有尸体中都存在且两侧对称。在所有观察到的情况下,它起源于环评的横向分支(100%),在98%的病例中,与IEA相反,与IL正后方。它沿着IL与ASIS的平均距离为7.28±0.99,而从耻骨结节到其起源的平均距离为5.91±1.03。它的长度范围从3.7厘米到9.5厘米,右肢平均长度为3.86厘米,左肢平均长度为3.67厘米。至于它的分支模式,在78%的案例中,它分叉成水平和上升的分支,6%,它以4%的比例分叉,它分为3个以上,表现出优良的树状分枝(乔木化)。
■我们的环境中的DCIA表现出与其他环境不同的变化,对这些变化的认识的提高可能会减少DCIA及其在肯尼亚的主要分支的未来医源性病变。
UNASSIGNED: The deep circumflex iliac artery (DCIA) is a large caliber artery which branches laterally from the external iliac artery (EIA), directly opposite the origin of the inferior epigastric artery (IEA). Population variations have been reported in its origin, length, and branching patterns. These may alter its relationship to palpable surgical landmarks such as the anterior superior iliac spine (ASIS) and the pubic tubercle (PT) which are used to locate the artery preoperatively, thus predisposing it iatrogenic injury. Despite this, there is paucity of data from the Kenyan setting.
UNASSIGNED: Cross-sectional study design.
UNASSIGNED: To determine the variations of the anatomy and bony landmarks of the Deep circumflex iliac artery in a select Kenyan population.
UNASSIGNED: A total of 104 DCIA from 52 formalin fixed adult cadavers were dissected to expose the DCIA, following which its vessel of origin and distance from the ASIS and PT, relation to the inguinal ligament (IL), length and branching patterns were noted. The average of the measurements were calculated. All data were collected and analyzed using Microsoft Excel 2007 (Microsoft Corporation, Redmond, WA). Representative photos of the vessel and its variations were taken.
UNASSIGNED: The DCIA was found to be present and bilaterally symmetrical in all cadavers. In all cases observed, it originated as a lateral branch from the EIA (100%), opposite the IEA and directly behind the IL in 98% of the cases. Its average distance from the ASIS along the IL was 7.28 ± 0.99, while it was 5.91 ± 1.03 from the pubic tubercle to its origin. Its length ranged from 3.7 cm to 9.5 cm, with an average length of 3.86 cm in the right limb and 3.67 cm in the left limb. As regards its branching patterns, in 78% of the cases, it bifurcated into the horizontal and ascending branches, in 6%, it trifurcated and in 4%, it divided into more than 3, exhibiting a fine tree-like branching (arborization).
UNASSIGNED: The DCIA in our setting exhibited variations from other settings and an increase in awareness of these variations will probably reduce future iatrogenic lesions of the DCIA and its major branches in Kenya.
