ABSTRACT
Objective To compare the CT features and clinic data of patients with congenital coarctation of the aorta ( CoA) and com-plex CoA. Methods CT findings and clinical characteristics of 29 patients with CoA were retrospectively analyzed and compared. Results There were difference in clinical characteristics between isolated COA and complex COA(P<0. 05). Local COA, aortic isthmus COA, associated with patent ductus arteriosus, bicuspid aortic valve were more than those of complex COA(all P<0. 05). Grade of vascular steno-sis in patients with isolated COA was higher than ones with complex COA. Isolated COA associated with vascular variations and aorta malfor-mation were less than those of Complex COA(P<0. 001). More cardiacvascular malformation were common in patients with complex COA, collateral circulation were in in all patients with isolated COA. Conclusion There were differences of CT findings in patients with different COAs. CT findings would be helpful for early diagnosis, treatment in early stage, and choice of treatment.
ABSTRACT
Objective To explore the CT manifestations of splenic artery aneurysm (SAA)in patients with liver cirrhosis,and its relationship with degree of cirrhosis.Methods SAA in 61 patients were confirmed from total 2 024 patients with liver cirrhosis but without hepatoma,and the clinic and CT data were retrospectively analyzed.Results SAA incidence rate of 3.0% (13.6% of women,1.5% of men,9.3% of portal hypertension and 10.2% of hypersplenotrophy)was observed in patients with liver cirrhosis. Multiple SAAs usually were showed with large round lesions (>1.0 cm)in the middle and distal segment of splenic artery and small fusiform ones (≤1.0 cm)in the branches of splenic artery (P =0.000).With the gradual deterioration of cirrhosis produce,the number and size of large aneurysms in proximal segment of splenic artery and number of small ones were increased with more inci-dence rates of calcification of aneurysm wall,haematoma of peri-aneurysm,mural thrombosis in SAA,megalosplenia/infarction of spleen and phlebeurysma (P =0.000).Conclusion Higher incidence rate of SAA in female patients with liver cirrhosis,portal hy-pertension and hypersplenotrophy is observed.CT can show well the location,number,size,shape and other features of SAA and portal hypertension,CT findings are correlated with the degree of cirrhosis,which may help for the treatment.
ABSTRACT
Objective To evaluate how to select operation procedures for different CT manifestation of splenic artery aneurysm ( SAA) with posthepatitic cirrhosis. Methods In 61 cases with SAA,the CT manifestation ( location,number,size,portal vein,varicose vein,proxi-mal splenorenal shunt and spleen changes) of SAA,clinical features of cases,and operation approach were were retrospectively analyzed. Re-sults 4 patients who have the primary tumors located in the distal splenic artery with diameter 1. 0~2. 0 cm,spleen kidney shunt and mega-losplenia were given aortic aneurysm exclusion and branch aneurysms embolism by stages. Amiong the 15 cases of tumors resection,splenecto-my and devascularization,there were 4 cases of the primary tumors located in the middle of splenic artery and 11 cases in the distal splenic artery. There were 15 cases whose diameter of the primary tumor were lager than 2. 0 cm and 13 cases whose diameter of the primary tumor were 1. 0~2. 0 cm. There were 4 cases of cavernous transformation of portal vein,5 cases of splenic and gastric varices,15 cases of esophage-al and gastric varices,4 cases of splenic and gastric venous shunt,15 cases of megalosplenia and 4 cases of splenic infarction. Tumors resec-tion and branch aneurysms embolism by stages were conducted in 7 cases. The primary tumors located in the proximal splenic artery occured in 7cases,and the diameter of the primary tumor were 1. 0~2. 0 cm occured in 7 cases. Esophageal and gastric varices occured in 2 cases and splenomegaly occured in 7 cases. And there were 4 cases whose diameter of the tumor were 1. 0~2. 0 cm were given tumor resection and re-construction of splenic artery and continuity, including 1 case of proximal splenic artery,2 cases of medial splenic artery and 1 case of distal splenic artery. Conclusion Operation procedures were confirmed by CT findings such as location,number,size,portal vein,varicose vein, proximal splenorenal shunt and spleen changes of SAA combined with age,gender,body mass index and history.
