The possibility of application of endovascular and two-stage combined revascularization of the penis in the arteriogenic ED treatment is shown. Twenty male patients with multifocal atherosclerotic lesions of the aorto-iliac-femoral segments underwent the analysis of the branching patterns of the IPA according to the classifcation by Adachi and Yamaki followed by the interventional endovascular intervention (angioplasty, stenting) of the iliac arteries. Seventeen patients underwent the unilateral and three patients – bilateral stenting of the common and external iliac arteries. Three patients out of the total number of the operated ones additionally underwent an open revascularization of the penis by epigastric-penic anastomosis. A complex preoperative examination of patients – candidates for revascularization of the penis for arteriogenic erectile dysfunction was performed and included ultrasound, МCT-angiography of the pelvic arteries, and electroneuromyographic examination of atherosclerotic lesions of the pool vessels of the inner pudental artery. Subsequently, endovascular and combined open revascularization operations were performed on the iliac and penis vessels. The erectile function improvement according to the IIEF-5 scale (8–12 scores before the operation vs 16–19 points after the operation) was noted in 1, 3, 6, 12 months (p< 0.05). Combined revascularization operations on the iliac and penis arteries (endovascular and open “bypass”) allow an adequate arterial blood perfusion to the penis in the steno-occlusive lesions of the pool vessels of the IPA affected by atherosclerosis.

Introduction. Secondary varicose small pelvic veins with the development of chronic venous insufficiency due to obstruction of the magistral venous vessels, in particular, the left common iliac vein and the right common iliac artery (May–Thurner syndrome), occupy a special place in the structure of the causes of venogenic erectile dysfunction (ED).The study objective is to present the clinical case of arteriovenous conflict (May–Thurner syndrome), leading to the development of secondary varicose small pelvic veins in men and venogenic ED, as well as modern methods of its verification and endovascular surgical repair.Clinical case. A clinical case of successful endovascular correction of venogenic ED is presented. The patient is diagnosed with: May– Thurner syndrome. Pelvic varicose disease С3 (according to CEAP Classification). Condition after endovascular balloon angioplasty and stenting of the left common iliac vein. Bilateral varicocele. Condition after bilateral varicocelectomy in 2018. Severe venogenic ED (pathological venous drainage, proximal type, International Index of Erectile Function (v. 5) – 12 points; Er3 according to the Unem Scale) in accordance with the Comprehensive Classification System for Chronic Venous Disorders. On July 24, 2019 endovascular occlusion of the Santorini’s plexus veins was performed with the installation of occlusion spirals in their lumen according to Gianturco. In order to provide visualization of the veins in the Santorini’s plexus, given the impossibility of cannulation of the deep vein of the penis, bilateral symmetrical cannulation of the cavernous bodies of the penis was carried out to perform cavernosophlebography. The left common iliac vein was catheterized according to the Crossover technique. Under phlebography control we ensured that the stent in the common iliac vein passed without signs of loss of its lumen. The internal pudental vein on the left was selectively catheterized. Hydrophilic guidewire was introduced through the veins of the periprostatic plexus into the right internal pudental vein. Selective catheterization of the periprostatic venous plexus was not possible due to pronounced tortuosity, valve flaps of the veins and small diameter of the catheterized veins. It was decided to pass the guidewire further through the right iliac vein system with access to the inferior vena cava. Further, the guidewire was again transferred to the left common iliac vein (double crossover). The left common femoral vein was punctured followed by the placement of 5 Fr introducer sheath according to Seldinger. The guidewire tip was fixed by the loop in the left common iliac vein, then captured and brought out through the introducer in the left common femoral vein. A catheter Сobra15 Fr was inserted through a crossover guide from the left common femoral vein into the right internal iliac vein and further into the periostatic venous plexus. Gradually veins of the Santorini’s plexus were selectively catheterized followed by Gianturco coils embolization.Conclusion. The first choice surgery for verified proximal type ED is endovascular occlusion of the veins in the Santorini’s plexus through the deep vein of the penis, which allows to change the hemodynamics in the penis and provide sufficient erection without resorting to endofalloprosthesis of the penis. Single or double-sided transfemoral access is suggested for patients when access through the deep vein of the penis is rather challenging or absent.

The study objective is to define the state of the problem of surgical methods for the treatment arteriogenic forms of erectile dysfunction (ED) in the Republic of Belarus, to systematize surgical methods for the correction of arteriogenic ED, to evaluate the results of interventional, surgical and combined methods of the treatment of arteriogenic forms of ED in the Republic of Belarus.Materials and methods. A comprehensive examination was carried out 65 men with arteriogenic ED (average age 52.2 ± 2.2 year, International Index of Erectile Function – 9.6 ± 1.3 points; the hardness of erection – 2.2 ± 0.3 according to the Yunem scale) included ultrasound, multispiral computed angiography, as results of stenosing and occlusive lesions of the aorto-iliac segments, internal pudendal artery (IPA) and distal branches were revealed. Of these, as a result of atherosclerotic damage to arteries – 59 (91 %) patients, hypoplasia of the IPA – 4 (6 %) patients and in 2 (3 %) – cases due to post-traumatic damage to the IPA during fracture of the pelvic bones. Pro- and retrospectively performed analysis of the results of endovascular, surgical and combined correction of chronic arterial insufficiency of penis. Based on the results of the study, blood flow deficiency was simulated in order to determine the possible level and method of its elimination. Subsequently, 34 reconstructive operations were performed, including endovascular: superselective stenting of IPA – in 1 case, angioplasty of IPA – one-bilateral – in 4 cases, stenting of the iliac arteries – in 14 cases, in 4 cases – aorto-femoral bypass or prosthetics. Microsurgical operations with epigastric-penile anastomosis were performed in 9 cases (Virag II type in 8 cases, Michal II – Scharlip in 1 case), including in 3 cases as a second stage to increase arterial perfusion of penis after endovascular interventions. In 3 cases, for severe arteriogenic ED and endothelial insufficiency, endophalloprosthesis was implanted (AMS-Spectra).Results. According to the results of testing of patients after endovascular intervention or microsurgical reconstruction, as well as after a two-stage correction that included both methods, patients showed a statistically significant improvement in erectile function on the scale of the International Index of Erectile Function – from 9–12 points (10.0 ± 0.31 points) before surgery to 16–19 points (17.5 ± 0.25 points) 12 months after surgery (p = 0.0009).Conclusions. Interventional methods of correction after micro surgical and combined operations in patients with arteriogenic ED allow achieving a satisfactory result during the first year after surgery, provided that patients are carefully selected using a comprehensive examination, including various ultrasound techniques, multispiral computed angiography, as well as the selection of an appropriate type of revascularization.
