Brief Summary:
This prospective randomized study compares the safety and efficacy of two different embolizing agents for the treatment of pelvic congestion syndrome: fibered platinum coils and vascular plugs.

Condition or disease Intervention/treatment Phase
Pelvic Congestion Syndrome Device: Fibered platinum coils Device: Vascular plugs Not Applicable

Detailed Description:
This prospective randomized study compares the safety and efficacy of two embolizing agents for the treatment of pelvic congestion syndrome: fibered platinum coils (Nester coils; Cook Medical) and vascular plugs (Amplatzer vascular plugs II; St. Jude Medical).

Primary Outcome Measures :
  1. Change in Pain Scale [ Time Frame: 12 months ]

    Reduction of 4 points or more between subjective pain assessed by VAS prior to procedure (-4, -5,- 6, -7,-8,-9).

    VAS= visual analogue scale: it is a subjective pain scale, scored from 1 to 10 (1 no pain; 10 worst pain possible)



Secondary Outcome Measures :
  1. Improvement of Dyspareunia [ Time Frame: 12 months ]
    Disappearance or improvement of dyspareunia assessed by direct questioning before the procedure and 12 months after the procedure (YES/NO)

  2. Improvement of Urinary Urgency [ Time Frame: 12 months ]
    Disappearance or improvement of urinary urgency assessed by direct questioning before the procedure and 12 months after the procedure (YES/NO)

  3. Improvement of Dysmenorrhea [ Time Frame: 12 months ]
    Disappearance or improvement of dysmenorrhea assessed by direct questioning before the procedure and 12 months after the procedure (YES/NO)

  4. Satisfaction With the Procedure [ Time Frame: 12 months ]

    Overall satisfaction with the procedure via telephone survey (scaled from 0 to 9).

    Patients answered just one question. Are you satisfied with the procedure? Being 0 = Completely unsatisfied, I regret having undergone a embolization procedure 9=Totally satisfied with the procedure, everything was perfect, I would recommend it to anyone with the same problem.


  5. Number of Devices Used [ Time Frame: intraoperative ]
    Number of coils and number of vascular plugs used in each procedure

  6. Cost of Treatment [ Time Frame: Intraoperative ]
    Cost of the differential devices used in each treatment procedure, assuming the same cost for the rest of the procedure, other material and hospital stay.

  7. Total Intervention Duration [ Time Frame: Intraoperative ]
    Total time length of the procedure, from puncture to compression (in minutes)

  8. Fluoroscopy Time [ Time Frame: Intraoperative ]
    Total fluoroscopy time, recorded by the equipment (in minutes)

  9. Procedure Radiation Dose (DAP) [ Time Frame: Intraoperative ]
    DAP, dose area product of the intervention, (in mGy*cm^2), recorded by fluoroscopy equipment

  10. Procedure Radiation Dose (AK) [ Time Frame: Intraoperative ]
    AK, total air kerma of the intervention (in mGy), recorded by fluoroscopy equipment

  11. Complications [ Time Frame: intraoperative ]
    Total number of events during the procedure

  12. Complications [ Time Frame: 12 months ]
    Toral number of events related to the procedure in the follow-up (1 year)

  13. Need for Re-embolization [ Time Frame: 12 months ]
    Scheduled re-embolization due to incomplete occlusion
