ABSTRACT
Purpose To investigate the significance of arterial phase display of right ovarian vein (ROV) for patients with pelvic congestion syndrome (PCS) through multi-slice CT angiography (MSCTA) Materials and Methods Forty-three patients with PCS confirmed clinically who underwent MSCTA were involved in the study. Revascularization was realized via add vessel volume rendering technique and maximum intensity projection (MIP) and the relationships among ROV early development, location of converging vascular, development of LOV and pelvic draining veins were analyzed. Results Out of 43 cases of ROV early development during arterial phase, 21 cases (48.8%) took ROV as draining vein of PCS, among which 17 cases (81.0%) converged into the inferior cava vena. In 19 cases (44.2%), ROV took part in the formation of PCS, all originating from the main right renal vein. Three cases (7.0%) were renal vein-derived PCS, among which two ROV originated from the main right renal vein and one from the branch of the right renal vein. Conclusion According to the imaging features of bilateral ovarian veins and pelvic veins, ROV, as draining veins, is associated with the formation of PCS.
ABSTRACT
Objective To explore the clinical application value of transcatheter arterial chemoembolization (TACE) combined with CT-guided percutaneous acetic acid injection (PAI) in treatment of huge hepatocellular carcinoma (HCC). Methods Forty-three patients with huge HCC were randomly divided into two group. Twenty-one patients in group A underwent routine one course for TACE (three times), and the interval of TACEs was one month. Twenty-two patients in group B underwent TACE combined with PAI, and CT-guided PAI was performed once a week since 2-3 weeks after first TACE, and one course included 6-9 times of PAI. Postoperative follow-up was conducted (including AFP, the size of tumor, etc.). One course of treatment was repeated in case of tumor recurred. Results At the 1st month after treatment, no statistical difference was found of AFP positive rate between two groups. Statistical difference of total effective rate was found between two groups (38.10% vs 77.27%). The 1-, 2- and 3-year survival rate In group A was 47.62%, 23.81% and 9.52%, respectively, while in group B was 81.82%, 54.55% and 36.36%, respectively, and significant differences were found between the two groups for the same period. Conclusion TACE combined with PAI is safe and more effective than TACE alone in the treatment of huge HCC.
ABSTRACT
Objective To explore the changes in fractional anisotropy (FA) among cerebral infarction pa-tients using MR diffusion tensor imaging (DTI), and to verify the relationship between any FA changes and functional recovery. Methods Thirty-eight cerebral infarction patients were divided into two groups according to their recovery level using Brunnstrom's criteria. All the patients accepted routine MR and DTI examination, and FA values were measured during the acute, subacute and chronic stages of their recovery. Results Average FA values in the lesion area were significantly lower than in the corresponding contralateral area, and were highest daring the acute stage.There was no significant difference between the subacute and chronic stages. Conclusions The FA values of cere-bral infarction patients change during the different stages of recovery with a certain regularity. This may be valuable for clinical treatment and prognosis.
ABSTRACT
Objective To investigate the value of MSCTA in diagnosing the origin of abdominal ectopic ovarian tumor. Methods Twenty-eight patients with 30 ectopic ovarian tumors that mainly manifested as abdominal lumps were evaluated with MSCTA retrospectively. Vascular three-dimensional reconstruction by VR based on add vessel (AV) and MIP was performed for all these patients after MSCT scanning.The origin of these tumors was judged by the feeding artery and ovarian vascular pedicle (OVP) sign.The result was compared with surgical findings.Results The maximum diameter of the 30 ectopic ovarian tumors ranged from 5.2 to 19.5 cm with an average of 9.3 cm.Of the 30 ectopic ovarian tumors, the ramus ovaricus arteriae uterinae (ROAU) and ovarian artery (OA) were demonstrated in 96.7% (29/30) and 56.7% (17/30) respectively.The feeding artery of the tumor was ROAU (29 cases) or OA (1 case), and OA participated in feeding the tumor in 16 cases.The accuracy rate of diagnosis of ectopic ovarian tumors according to the feeding artery was 100% (30/30).According to OVP the accuracy rate was 85.2% (23/27) with an incidence of 76.7% (23/30).Conclusion By showing ROAU and OA as the feeding artery and ovarian vein (OV) as the draining vein, MSCTA can accurately diagnose ectopic ovary tumors in the abdomen.
