Síndrome de congestión pélvica: revisión actualizada de la literatura / Pelvic congestion syndrome: updated literature review

El síndrome de congestión pélvica (SCP) es una causa frecuente, aunque poco conocida, de dolor pélvico crónico en mujeres premenopáusicas. Aunque su etiología no está del todo clara, en general se acepta la incompetencia valvular como causa del SCP primario, mientras los síndromes compresivos llevan al SCP secundario. El diagnóstico de este síndrome se realiza después de excluir otras causas de dolor pélvico crónico y se basa en una combinación de síntomas clínicos característicos (dolor crónico, continuo o sordo, dispareunia, dismenorrea...) y en la documentación de dilatación o incompetencia de las venas pélvicas mediante pruebas de imagen. La terapia endovascular (escleroterapia, embolización o stent) de las venas incompetentes con reflujo o venas estenóticas constituye el estándar de tratamiento. El objetivo del presente trabajo es realizar una revisión actualizada de la literatura con el propósito de ayudar a mejorar el conocimiento de esta patología

Pelvic congestion syndrome (PCS) is a common, but little-known, cause of chronic pelvic pain in premenopausal women. Although its etiology is not entirely clear, valvular incompetence is generally accepted as the cause of primary PCS, while compressive syndromes lead to secondary PCS. The diagnosis of this syndrome is made after excluding other causes of chronic pelvic pain, and is based on a combination of characteristic clinical symptoms (chronic pain, continuous or dull, dyspareunia, and dysmenorrhea) and documentation of dilation or incompetence of pelvic veins by imaging tests. Endovascular therapy (sclerotherapy, embolization or stenting) of incompetent and reflux veins or stenotic veins, is today the standard of treatment. The objective of this work is to carry out an updated revision of the literature with the purpose of helping to improve the knowledge of this pathology

[Varicocele's radiological endovascular occlusion]. / Oclusión radiológica endovascular del varicocele.

OBJECTIVES: To report our experience on percutaneous treatment of male varicocele over the last 15 years. METHODS: 690 patients with left varicocele underwent percutaneous occlusion of the spermatic vein. Embolization was undertaken using various types of materials; the most frequently used association was coils and sclerosing substances. Thorough clinical control was carried out, including ultrasound and spermiogram when indicated. RESULTS: Initial success rate was 97.8% and complication rate was 6.2%. Varicocele persistence or relapse was found in 13.2% of the cases after embolization. In the group of patients with sperm tests on follow-up, sperm counts became normal in 46% of the patients, and "a + b" mobility in 35%. Post-treatment pregnancy rate was 20%. CONCLUSIONS: Percutaneous occlusion of the spermatic vein is a very extensively developed technique. Its efficacy and nearly null rate of severe complications, associated with its good results, make it the technique of choice in the treatment of male varicocele.

[The treatment of varicocele in the infertile male I: results on semen quality]. / Tratamiento del varicocele en el varón infértil I: resultados sobre la calidad seminal.

OBJECTIVES: To evaluate the effect of interventionist treatment of varicocele, either open surgery or endovascular radiological occlusion, on seminal parameters, and to identify which factors are associated with their normalization. METHODS: Between 1975 and 2000, 631 patients with the diagnosis of idiopathic varicocele were evaluated in our hospital; 238 of them were part of an infertile couple. Among them, finally, 183 underwent studies; they complied with the following criteria: 1) Infertility for more than one year; 2) seminal parameters below normality following WHO criteria (1992); 3) absence of other pathologies or diseases which could explain male infertility; and 4) absence of evident causes of male infertility. 131 patients were treated by radiological occlusion and 26 by conventional surgery. The remaining 26 patients did not undergo the treatment indicated. Two parameters were evaluated on follow-up: 1) achievement of pregnancy (these results will be analyzed in a next article), and 2) normalization of seminal parameters. RESULTS: 48% and 39% of the patients respectively achieved normalization of the number of spermatozoids per ml (=20 million spermatozoids per ml) and spermatic morbidity (=50%). The association between normalization of seminal parameters and age, clinical grade, or type of treatment was not demonstrated. Only baseline degree of severity in the alteration of seminal parameters showed statistically significant differences in the evaluation of semen quality after treatment of varicocele (p = 0.001 and p = 0.002). CONCLUSIONS: The degree of previous seminal alteration--oligospermia and asthenospermia--was the factor with greatest prognostic value in relation with normalization of seminal parameters.
