This retrospective study will enroll patients with pelvic venous disorders who have undergone pelvic vein surgery and endovascular interventions. Three groups of patients will be formed. The first will include patients who underwent open retroperitoneal resection of the gonadal veins and endoscopic trans- and retroperitoneal resection of the gonadal veins. The second group will include patients who underwent embolization of the gonadal veins with coils, the third - patients who underwent stenting of the common iliac veins, or stenting of the iliac veins in combination with embolization of the gonadic veins with coils. Evaluation of the effectiveness and safety of interventions on the pelvic veins will be carried out by assessing the effect of the intervention on pelvic pain, morphological and functional state of the pelvic veins. The assessment of the safety of interventions on the pelvic veins will be carried out by assessing the severity of post-procedural pain, the frequency of complications of operations on the pelvic veins, and complications of anesthesia. In addition, the duration of pelvic vein interventions will be compared with the length of time the patient is in hospital. Based on the data obtained, an algorithm will be proposed for determining the choice of the method of interventions on the pelvic veins in patients with pelvic venous disorders.
This retrospective study will include patients with pelvic venous disorders (ovarian venous insufficiency, compression stenosis of the left or right common iliac vein) who underwent surgical and endovascular interventions on the pelvic veins during 2000-2021. The database of the local system "Interin" of the First City Hospital of Moscow (Russia) will be used, into which all information about patients with pelvic venous diseases during 2000-2021 was entered.
In this study, the pelvic veins included the gonadal, parametric, uterine, common, external and internal iliac veins.
Indications for intervention on the gonadal veins are symptoms and signs of pelvic venous disorder (pelvic pain, dyspareunia, heaviness in the hypogastric region, vulvar varicose veins) in combination with the expansion of the gonadal veins of more than 5 mm and reflux in them for more than 1 s.
The indication for intervention on the left / right common iliac vein is the presence of compression stenosis of these veins of more than 50% in combination with symptoms and signs of pelvic venous disease.
Three groups of patients will be formed. The first will include patients with ovarian venous insufficiency, dilation of the gonadal veins of more than 10 mm and reflux along them for more than 1 s, who underwent open retroperitoneal resection and endoscopic trans- and retroperitoneal resection of the gonadal veins.
The second group will include patients with ovarian venous insufficiency, dilatation of the gonadal veins less than 10 mm and pelvic venous reflux for more than 1 s, who have undergone embolization of the gonadal veins with coils.
The third will include patients with a combination of May-Thurner-Cockett syndrome and pelvic congestion syndrome who have stenting of the common iliac veins, or stenting of the iliac veins in combination with embolization of the gonadal veins with coils.
Evaluation of the effectiveness and safety of interventions on the pelvic veins will be carried out by assessing the effect of the intervention on pelvic pain, morphological and functional state of the pelvic veins. A visual analogue scale will be used to assess the dynamics of pelvic pain after gonadal and iliac vein interventions.
The assessment of the morphological and functional state will be carried out using the results of transabdominal and transvaginal duplex ultrasound (diameter of the pelvic veins, linear blood flow velocity through them, the presence of reflux in these veins and its duration).
The assessment of the safety of interventions on the pelvic veins will be carried out by assessing the severity of post-procedural pain, the frequency of complications of operations on the pelvic veins, and complications of anesthesia.
Postoperative / Postprocedural pain was assessed using a visual analogue scale.
Complications of gonadal and iliac vein interventions were assessed within 1-30 days after surgery. Complications of gonadal vein resection included:
Complications of gonadal vein embolization with coils included:
Complications of stenting of the common iliac vein included:
ased on this study of data, objective information will be obtained on the effectiveness and safety of interventions on the gonadal and iliac veins, and an algorithm will be proposed for determining the choice of the method of interventions on the pelvic veins in patients with pelvic venous disorders.
