Association between Clinical and Ultrasonic Characteristics of Varicocele and Lower Extremity Varicose Vein in Men

Association between lower extremity venous insufficiency and increased choroidal thickness

PURPOSE

The goal of this study is to investigate the association between the choroid and lower extremity venous insufficiency (LEVI).

METHODS

This prospective cross-sectional study includes 56 patients with LEVI and 50 age/sex-similar control subjects. Choroidal thickness (CT) measurements from 5 different points were captured from all participants by optical coherence tomography. In the group with LEVI on physical examination, reflux at the saphenofemoral junction, and the diameter of the great and small saphenous veins were evaluated via color Doppler ultrasonography.

RESULTS

The mean subfoveal CT was higher in the varicose group than in the control group (363.04±99.75μm vs. 320.30±73.46μm, P=0.013). In addition, the CTs at the temporal 3mm, temporal 1mm, nasal 1mm, and nasal 3mm distance from the fovea were higher in the LEVI group compared to the controls (for all, P<0.05). There was no correlation between CT and diameter of the great and small saphenous vein in patients with LEVI (for all, P>0.05). However, the great and small saphenous veins of patients with CT above 400μm were observed to be wider in patients with LEVI (P=0.027 and P=0.007, respectively).

CONCLUSION

Varicose veins can be a feature of systemic venous pathology. Another component of systemic venous disease may be increased CT. Patients with high CT should be investigated for susceptibility to LEVI.

The association between varicocele and other vascular diseases: A systematic review and meta-analysis

OBJECTIVE

This study is aimed to evaluate the association between varicocele and other vascular diseases through a systematic reviews and meta-analyses.

MATERIAL AND METHODS

We searched Cochrane Central Register of Controlled Trials, Embase, PubMed, and Web of Science for studies that reported varicocele and other vascular diseases published before 30 June 2021. The meta-analysis was performed by Revman V.5.2 to calculate the pooled odds ratios and corresponding 95% confidence intervals. Subsequently, the impact of publication bias was evaluated, and sensitivity analysis as performed to assess our results' robustness.

RESULTS

In total, seven case-control studies, including 803 varicocele cases and 727 controls, were included. Our meta-analysis results showed that the varicocele patients had a higher risk of saphenofemoral insufficiency when compared with the control group (odds ratio [OR]: 2.80; 95% confidence intervals [CIs]: 2.03, 3.84; p < 0.00001). Additionally, varicocele patients also had a higher risk of lower extremity venous insufficiency when compared with the control group (OR: 2.34; 95% CI: 1.58, 3.47; p < 0.0001). However, there was no statistical difference in hemorrhoid risk between both groups (OR: 1.13; 95% CI: 0.28, 4.59; p = 0.87).

CONCLUSION

Our study demonstrated that varicocele patients have higher risk of saphenofemoral and lower extremity venous insufficiencies but not the risk of hemorrhoids.

Evaluation of hemorrhoidal disease and lower extremity venous insufficiency in primary adult varicocele: A prospective controlled study

Background

The study investigated the association between varicocele, lower extremity venous insufficiency and hemorrhoidal disease.

Methods

The study included 62 patients with varicocele and 60 voluntary subjects with no varicocele. Patients who were diagnosed as having varicocele on physical examination and Doppler ultrasonography were included in the study group. Examination of lower extremity venous insufficiency was performed by physical examination and Doppler ultrasonography. Examination of hemorrhoidal disease was performed by a general surgery specialist.

Results

The patients with varicocele had a statistically significant ( p < 0.05) higher rates of venous insufficiency of the lower extremities and had a borderline significant difference of higher hemorrhoidal disease rates ( p = 0.05). Therewithal incidences of hemorrhoidal disease and lower extremity venous insufficiency were significantly higher in body mass index > 25 and age > 30 years of varicocele patients.

Conclusion

There is a statistically significant relation between varicocele, lower extremity venous insufficiency, and hemorrhoidal disease. In particular, varicocele patients who are aged over 30 years and overweight are at higher risk.
