Abstract:
Objective:To evaluate the application of three‐dimensional(3D) rotational digital subtraction angiography(DSA) and three‐dimensional reconstruction technique in the interventional treatment of visceral artery aneurysm .Methods:A total of 25 patients with visceral artery aneurysm ,who underwent 3D rotational DSA and reconstruction before the interventional embolization treatment in the Department of Interventional Radiology ,Zhongshan Hospital ,Fudan University during Jan 2007 and Aug 2015 ,were selected .3D rotational DSA and reconstruction was performed by using Siemens Artis DTA or Philips Allura F20 DSA equipment ,and the results were compared with that of conventional 2D DSA .Results:There were 8 hepatic artery aneurysms ,10 splenic artery aneurysms ,3 renal artery aneurysms ,3 gastroduodenal artery aneurysms ,and 1 inferior pancreaticoduodenal artery aneurysm among the 25 patients .The 3D rotational DSA procedures were successful in all patients , and the success rate was 100% .Anatomical morphology including the diameter ,neck and cavity of aneurysm was exhaustively demonstrated .A total of 30 aneurysms were diagnosed by 3D rotational DSA among the 25 patients .Among the 30 aneuryms , only 27 aneurysms were confirmed by conventional 2D DSA ,and the aneurysm necks of 15 aneurysms were not exhaustively demonstrated due to the anatomical overlapping of the large aneurysm cavity , or the vessel tortuosity . Conclusions: As compared to the conventional 2D DSA ,the 3D rotational DSA and reconstruction can demonstrate anatomical information of visceral artery aneurysms more precisely , especially the aneurysm neck , so as to provide more precise images for the interventional diagnosis and treatment .
