DOPPLER US OF THE EXTREMITY 2192 Role of color Doppler ultrasonography for the evaluation of vulvar varices Jin KN, Lee W, Cho YK, Jung JW, Park JH, Seoul National University Hospital, Korea; Seoul National University College of Medicine, Korea Objectives: To reveal the diagnostic role of color Doppler ultrasonog- raphy to demonstrate vulvar varices arising from the pelvic vein and exclude other cause of vulvar varices. Methods: Sixty patients underwent CT venography for the vulvoperi- neal varices; nine of them with vulvar varices and atypical varicose veins on the medial side of the upper thighs were selected for the ultrasonography to demonstrate venous reflux of vulvar varices from the pelvic vein. Color Doppler and pulsed-wave Doppler ultrasonog- raphy were enrolled to detect perforators and to estimate direction and flow rate of venous reflux. Valsalva maneuver was used to provoke the venous reflux. Results: In nine patients who had vulvar varices communicating with the atypical varicose veins on the medial side of the upper thigh, color Doppler ultrasonography demonstrated venous reflux from the pelvic vein and could exclude saphenofemoral insufficiency. Conclusions: Vulvoperineal varices have different causes such as pelvic vein insufficiency, saphenofemoral insufficiency or post-throm- botic syndrome. Careful color Doppler ultrasonography is the appro- priate noninvasive means to establish diagnosis of vulvar varices aris- ing from the pelvic vein and rule out saphenofemoral insufficiency. 2193 Varicose veins of the lower extremity: Color Doppler ultrasound study for incompetent sapheno-femoral junction, sapheno- popliteal junction and perforating veins Kim SK, Hong SJ, Park CM, Cha IH, Kim HJ, Korea University Guro Hospital, Korea Objectives: We evaluated the incidence and severity of incompetent sapheno-femoral junction (SFJ), sapheno-popliteal junction (SPJ) and perforating veins (PVs) by color Doppler ultrasound (CDUS) in pa- tients with varicose veins of the lower extremity. Methods: On CDUS, varicose veins were demonstrated in 346 lower extremities of 241 patients. There were 96 men and 145 women with mean age 50 (range 11 to 74). CDUS was focused on the incompetence at SFJ, SPJ, and PVs. The severity of SFJ and SPJ incompetence were graded as I (minimal) to IV (severe). SFJ was evaluated on supine and standing positions with and without Valsalva’s maneuver. SPJ was evaluated on prone and standing positions with and without Valsalva’s maneuver. Distension or reflux was considered as a sign of incompetent PVs. Results: SFJ incompetence was noted in 198 (57.2%) cases, SPJ incompetence in 81 and incompetence of both SFJ and SPJ in 21. Incompetent PVs was seen in 54. No incompetence was demonstrated in 34 (9.8%). Among SFJ incompetence, 75 were in grade II, 73 were in grade III. Among SPJ incompetence, grade III was most common. Conclusions: SFJ incompetence is a major cause of varicose veins in lower extremity. Varicose veins can be present without incompetence at SFJ, SPJ, PVs. 2194 Duration and velocity of reflux obtained by color Doppler as prognostic criteria of chronic venous insufficiency Goldina IM, Trofimova EY, Kungurtsev EV, N.V. Sklifosovsky Research Institute of Emergency Medical Aid, Moscow, Russian Federation Objectives: Duration and peak velocity of the reflux at the sapheno- femoral junction (SFJ) were investigated in patients with chronic venous insufficiency (CVI) according to the CEAP (clinical, etiologic, anatomic, pathophysiologic) clinical classification to determine prog- nostic value of the ultrasound (US) diagnostic criteria. Methods: Color Doppler (CD) and Valsalva’s maneuver have per- formed to determine the incompetence of SFJ in patients with different clinical classes of CVI according classification CEAP. The clinical series contained 174 patients (254 extremities), control group was 26 patients (52 extremities). Results: It was obtained that 118 (170 lower extremities) patients with clinical signs of CVI were possesed SFJ failure. The duration of the reflux was more 0.5 sec. The duration of the reflux positive prognostic value was 0.98 (Se: 0.68, Sp: 0.94, r 0.9657, p 0.001). Mean value of peak velocity of reflux at the SFJ was from 14.8 3.5 cm/s (C0 clinical class of CVI) to 68.4 4.1 cm/s (C5 clinical class of CVI). Peak velocity positive prognostic value was 0.9 (Se: 0.9, Sp: 0.78, p 0.001). Conclusions: Duration and velocity reflux criteria are better predictors of the progression of chronic venous insufficiency and that they cor- relate well with the severity of the clinical manifestation of chronic venous insufficiency. 2195 Revisiting the significance of monophasic waveforms on DVT evaluation Lin E, Bhatt S, Ormanoski M, Rubens D, Dogra V, Strong Memorial Hospital, United States of America Objectives: Assess the significance of monophasic waveforms in the common femoral veins in deep venous thrombosis (DVT). Methods: Lower extremity venous Doppler ultrasounds (US) per- formed at Strong Memorial Hospital from 1 September 2003 through 1 September 2005 were reviewed retrospectively. Studies, meeting the AIUM criteria, were evaluated for monophasic waveforms, and correl- ative studies were reviewed. Patients less than the age of 17 were excluded from the study. Results: One thousand thirteen lower extremity venous Doppler US examinations were reviewed; 59 of these studies demonstrated monophasic waveforms, of which 41 had additional CT examinations of the abdomen and pelvis within 1 week, 9 within 2 months, 5 with no additional exams; 23/59 cases revealed DVT above the level of the common femoral vein, of which six were identified by US; 7/59 were due to extrinsic compression. 26/59 had no apparent cause for monophasic waveforms; 3/59 were secondary to hypoplastic common iliac veins. Conclusions: Two fifth of the cases with monophasic waveforms demonstrated DVT above the level of the common femoral veins. We recommend including Doppler examination of the external iliac veins in patients who exhibit monophasic waveforms. A prospective study should be undertaken to further evaluate the role of adjunctive CT studies in patients with unexplained monophasic waveforms. 2196 Role of ultrasound in evaluation of unilateral leg swelling Shaukat A, Mayo Hospital, Lahore, Pakistan Objectives: To know the effectiveness of high resolution USG in evaluation of unilateral leg swelling.
