BACKGROUND
Angiography of the superior rectal artery showed that its branches were divided into four main branches (two left and two right) in 46.8%; the second most frequent variation was one right and two left branches in 26.6%, followed by two branches to the right and one to the left in 20%; the most uncommon variations were one to the right and one to the left without further subdivision in 6.6%.
BACKGROUND
◼ The superior rectal artery, when it reaches the rectum, divides into two or more branches.
BACKGROUND
◼ Four patterns were observed in the angiographic anatomy of the superior rectal artery.
BACKGROUND
◼ Understanding the angiographic anatomy of the superior rectal artery is important to achieve optimal embolization results.
OBJECTIVE
To describe angiographic findings of the superior rectal artery, its branches, and anatomical variations in the hemorrhoidal plexus in patients undergoing rectal artery embolization for hemorrhoidal disease treatment.
METHODS
Angiographic findings of 15 patients were obtained from a single-center, prospective clinical study that compared superior rectal artery embolization with the Ferguson technique for hemorrhoidal disease between July 2018 and March 2020.
RESULTS
Angiography of the superior rectal artery showed that in seven patients (46.8%), its branches were divided into four main branches (two left and two right), while in four patients (26.6%), the branches divided into one right and two left branches. The most uncommon variation observed in three cases (20%) was the branches divided into two branches to the right and one to the left; no further subdivision into the main branches was observed in one case (6.6%).
CONCLUSION
Four patterns were observed in the angiographic anatomy of the superior rectal arteries. Knowledge of the angiographic anatomy of this region and its variations is essential to improve the effectiveness of superior rectal artery embolization.
REGISTRY OF CLINICAL TRIALS
NCT03402282.
背景
直肠上动脉血管造影显示，其分支在46.8%的情况下分为四个主要分支（两个左侧分支和两个右侧分支）；第二常见的变异情况是一个右侧分支和两个左侧分支，占26.6%，其次是两个右侧分支和一个左侧分支，占20%；最不常见的变异情况是一个右侧分支和一个左侧分支且无进一步细分，占6.6%。
背景
◼ 直肠上动脉到达直肠时分为两个或更多分支。
背景
◼ 在直肠上动脉血管造影解剖中观察到四种模式。
背景
◼ 了解直肠上动脉血管造影解剖对于获得最佳栓塞效果很重要。
目的
描述接受直肠动脉栓塞治疗痔病患者的直肠上动脉及其分支的血管造影表现以及痔丛的解剖变异。
方法
从一项单中心前瞻性临床研究中获取15例患者的血管造影结果，该研究在2018年7月至2020年3月期间比较了直肠上动脉栓塞与弗格森技术治疗痔病的效果。
结果
直肠上动脉血管造影显示，7例患者（46.8%）的分支分为四个主要分支（两个左侧分支和两个右侧分支），而4例患者（26.6%）的分支分为一个右侧分支和两个左侧分支。在3例患者（20%）中观察到的最不常见变异是分支分为两个右侧分支和一个左侧分支；1例患者（6.6%）未观察到进一步细分为主要分支的情况。
结论
在直肠上动脉血管造影解剖中观察到四种模式。了解该区域的血管造影解剖及其变异对于提高直肠上动脉栓塞的有效性至关重要。
