The Clinical Value Of Multi-slice Spiral Computed Tomography Angiography In Pelvic Venous Congestion Syndrome

ObjectiveThe congestion of ovarian vein vascular and pelvic venous plexus werereconstructed by using multislice CTA for the expansion of pelvic venouscongestion syndrome (PCS).To study the clinical value of multi-slice spiral CTangiography in the diagnosis of pelvic venous congestion syndrome.Methods38patients with pelvic venous congestion syndrome and46patients duringthe same period by other system diseases diagnosis (excluding gynecologicaldisease) patients as control group, two groups were performed MSCTA. Allenhanced scanned CT images were reconstructed into volume images after spiralscanning.The obtained images of MPR and VR, MIP reconstructions,two-dimensional images measuring the left ovarian vein in MSCT and besideuterine vein diameters.Two senior imaging diagnostic doctors viewedrespectively from different angles of pelvic vein and the left ovarian veinposition, number, shape, etc in double-blind method on MSCT scan andenhanced scan images. Statistics between the two groups data, To dicide whetherthere is a statistically significant between the two groups were compared thepelvic veins and the left ovarian vein diameter,between the pelvic venous plexuscontrast clearance time; To dicide whether there is a statistically significantbetween the two groups of the enhancement of ovarian vein during the arterialphase.ResultsMSCT and angiography images technology can demonstrate the dilated，tortuous parametrial venous plexus and ovarian vein， confirming the diagnosis of pelvic congestion syndrome． The diameter of the left ovarian vein betweenpelvic venous congestion syndrome of the patients and in the control group are8.7±1.6mm,5.4±1.1mm,respectively.Pelvic venous plexus the coarse venousdiameter:7.2±1.2mm,3.5±0.46mm,respectively, between the two groups havestatistically significant differences (P <0.001).The left ovarian vein and thedeveloping situation of pelvic venous plexus,30cases of pelvic venouscongestion syndrome in the left ovarian vein imaging shows early ovarianvenous insufficiency, its presence of regurgitation or expansion of pelvic venousplexus of abnormal traffic between and around the small artery, the left ovarianvein-arterial enhancement between two groups had obvious statisticalsignificance. Pelvic venous congestion syndrome patients (38cases) beside thepalace venous plexus and inferior vena cava in delay appeared more obviousdifference of CT values36±4.8HU (CT difference greater than30HU),twogroups was statistically significant between contrast material removal time,explain the patients of pelvic venous congestion syndrome does blood stream isslow and prolonged contrast agent to clear the phenomenon.ConclusionMSCT and angiography images technology can demonstrate the dilated，tortuous parametrial venous plexus and ovarian vein,confirming the diagnosis ofpelvic congestion syndrome.Pelvic venous congestion syndrome of blood flowdeposition with pelvic venous plexus in patients, slow clearance of contrastagent time were observed.Part of patients in pelvic venous congestion syndromewere observed arterial enhancement phenomenon in ovarian veins and pelvicvenous plexus, which to prove ovarian venous insufficiency,reflux its existenceand expansion of pelvic venous plexus and small artery formed abnormaltraffic.MSCT and vascular imaging technology can display the vascular anatomyof pelvic venous congestion syndrome in all directions,display clearly andintuitive varicose veins and their secondary cause,MSCT and angiographyimages technology have important clinical significance for the choice of clinicaltreatment and surgery to provide accurate, objective diagnosis.
