“…Pulsatile flow in varicose veins has also been described previously to support a hypothesis of arteriovenous fistulae in the pathogenesis of varicose veins [17]. The morphologic changes detected by computed tomogram-venography (CTV) might be a clue to predict the saphenous vein insufficiency [18,19]. Lee et al [18] evaluated CTV finding of saphenous venous insuffiency.…”

PurposeIncreased saphenous vein diameter is a common consequence of saphenous vein reflux. Until now, there have been no reports about the correlation between diameter and reflux of saphenous vein in Korea. The aim of this study was to investigate the correlation between saphenous vein reflux and diameter changes.MethodsFrom April 2009 to August 2012, 777 patients were sent to the vascular laboratory for evaluation of venous reflux. The diameter of the saphenous vein was measured with B-mode imaging, and reflux was quantified based on valve closure time using Doppler spectral tracings. Receiver operating characteristics curve analysis was applied to determine the best saphenous vein diameter cutoff for predicting reflux.ResultsThe mean diameters of normal great saphenous vein (GSV) and refluxed GSV were 5.0 ± 2.4 mm and 6.4 ± 2.0 mm, respectively. The mean diameters of normal small saphenous vein (SSV) and refluxed SSV were 3.1 ± 1.3 mm and 5.2 ± 2.7 mm, respectively. The diameter differences between the normal and refluxed GSV and SSV were 1.4 mm and 2.1 mm, respectively, and these differences were statistically significant (P < 0.0001). A GSV threshold diameter of 5.05 mm had the best positive predictive value for reflux. The sensitivity and specificity at 5.05 mm were 76% and 60%, respectively. The best SSV diameter for predicting reflux was 3.55 mm. The sensitivity and specificity at 3.55 mm were 87% and 71%, respectively.ConclusionGSV diameter of ≥5.05 mm had the best positive predictive value for pathologic reflux. For pathologic reflux of SSV, the best cutoff diameter was 3.55 mm.

Purpose The Cobb angle as an objective measure is used to determine the progression of deformity, and is the basis in the planning of conservative and surgical treatment. However, studies have shown that the Cobb angle has two limitations: an inter-and intraobserver variability of the measurement is approximately 3-5 degrees, and high variability regarding the definition of the end vertebra. Scoliosis is a three-dimensional (3D) pathology, and 3D pathologies cannot be completely assessed by two-dimensional (2D) methods, like 2D radiography. The objective of this study was to determine the intraobserver and interobserver reliability of end vertebra definition and Cobb angle measurement using X-rays and 3D computer tomography (CT) reconstructions in scoliotic spines. Methods To assess interoberver variation the Cobb angle and the end vertebra were assessed by five observers in 55 patients using X-rays and 3D CT reconstructions. Definition of end vertebra and measurement of the Cobb angle was repeated two times with a three-week interval. Intraclass correlation coefficients (ICC) were used to determine the interobserver and intraobserver reliabilities. 95% prediction limits were provided for measurement errors. Results Intraclass correlation coefficient (ICC) showed excellent reliability for both methods. The measured Cobb angle was on average 9.2 degrees larger in the 3D CT group (72.8°, range 30-144) than on 2D radiography (63.6°, range 24-152). Conclusions In scoliosis treatment it is very essential to determine the curve magnitude, which is larger in a 3D measurement compared to 2D radiography.

Historically, idiopathic varicocele is the most commonly diagnosed pre-pubertal andrological condition. The clinical presentation of varicocele may vary from dull and dragging unilateral or bilateral testicular pain to visible varicose veins lying over the hemiscrotum. Over the last decade, significant strides were made in managing symptomatic varicoceles, particularly minimal invasive procedures and surgeries. We sought to review the published literature in a systematic manner to gain an overview and streamline the presentations and main treatment modalities.

Role of three-dimensional computed tomography venography as a powerful navigator for varicose vein surgery

Abstract: CT venography can provide excellent road map for VV surgery without significant complications. It cannot replace duplex ultrasound, but can provide powerful 3D images for designing operation as well as education and research.
