Abstract
Chronic venous insufficiency and varicose veins occur commonly in affluent countries and are a socioeconomic burden. However, there remains a relative lack of knowledge about venous pathophysiology. Various theories have been suggested, yet the molecular sequence of events is poorly understood. Transforming growth factor-beta one (TGF-β1) is a highly complex polypeptide with multifunctional properties that has an active role during embryonic development, in adult organ physiology and in the pathophysiology of major diseases, including cancer and various autoimmune, fibrotic and cardiovascular diseases. Therefore, an emphasis on understanding its signaling pathways (and possible disruptions) will be an essential requirement for a better comprehension and management of specific diseases. This review aims at shedding more light on venous pathophysiology by describing the TGF-β1 structure, function, activation and signaling, and providing an overview of how this growth factor and disturbances in its signaling pathway may contribute to specific pathological processes concerning the vessel wall which, in turn, may have a role in chronic venous insufficiency.

Superior Petrosal Vein Sacrifice During Microvascular Decompression: Perioperative Complication Rates and Comparison with Venous Preservation. World Neurosurg 2017; 104:788-794. [PMID: 28559083 DOI: 10.1016/j.wneu.2017.05.098] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2017] [Revised: 05/15/2017] [Accepted: 05/18/2017] [Indexed: 11/18/2022]
Abstract
OBJECTIVE To investigate potential effect of sacrifice of the superior petrosal vein (SPV) on postoperative complications after microvascular decompression (MVD). METHODS Retrospective review of 98 consecutive patients undergoing MVD of cranial nerve V was performed. Frequency of division of the SPV during surgery was recorded, and postoperative complications and imaging were recorded and analyzed. In patients with complications, the specific anatomic variation of the superior petrosal venous complex was noted. RESULTS Of 98 patients undergoing MVD, 83 (84.7%) had sacrifice of the SPV at the time of surgery, 12 (12.2%) had the SPV preserved, and 3 (3.1%) were revision operations. Four patients (4.8%) had complications deemed to be attributable to venous insufficiency or congestion. These included sigmoid sinus thrombosis with coincident cerebellar hemorrhage, midbrain and pontine infarction, hemiparesis with midbrain and pontine edema, and facial paresis with ischemia in the middle cerebellar peduncle. None of the patients with preserved SPV were symptomatic or had imaging changes consistent with venous congestion. CONCLUSIONS Sacrifice of the SPV is often performed during MVD. This is associated with a complication rate that is significant in frequency and severity compared with preserving the vein. SPV sacrifice should be limited to cases where it is deemed absolutely necessary for successful cranial nerve decompression.

Abstract
Chronic venous insufficiency is an often-missed diagnosis that results in a variety of clinical manifestations that may severely compromise quality of life. Prompt recognition is important to provide symptomatic relief and prevent disease progression. Most patients can be treated with a comprehensive plan of conservative measures. However, it is important for providers to recognize those patients who require referral to a vascular specialist for more invasive therapies. Over the past 2 decades, a variety of endovenous strategies have demonstrated effective and lasting results in treatment of severe symptomatic venous insufficiency.

Abstract
Venous reflux is the most common cause of venous hemodynamic disorders. In this paper 2 issues are discussed: how and where does reflux arise and what are the hemodynamic consequences of retrograde flow. Pressure gradient and incompetent vein connecting both poles of the gradient are the prerequisite for venous reflux to arise. Ambulatory pressure gradient occurs during the activity of the calf muscle venous pump between deep veins of the thigh and the lower leg. Thus the incompetent reflux-carrying vein must connect the popliteal, femoral, profunda femoris, or iliac vein with 1 of the deep veins of the lower leg. Reflux can be considered as shunting of blood from thigh veins into the lower leg veins. The most frequently found incompetent veins are the long and short saphenous veins and perforators communicating with deep veins of the thigh. On the other hand, calf perforators emptying into the deep veins of the lower leg, where the lower pole of the pressure gradient is located, cannot be the feeding source of reflux. A physiological bidirectional flow takes place in calf perforators connecting superficial and deep veins of the lower leg and making them conjoined vessels. Venous reflux produces ambulatory venous hypertension. The quantity of reflux volume and not the localization of retrograde flow in superficial or deep veins is the most important hemodynamic factor. Reflux in superficial veins, when large enough, can cause the most serious symptoms of chronic venous insufficiency including leg ulcers. Plethysmographic findings have shown that incompetence of the femoral and calf perforating veins is hemodynamically unimportant. Large incompetent calf perforators are not the cause of venous abnormality but are the consequence of saphenous retrograde flow.

Abstract
The aim of this open study was the evaluation of the effects of HR (Venoruton®) at a dose of 1 g/day on the prevention and control of flight microangiopathy and edema in subjects with varicose veins and moderate chronic venous insufficiency flying for more than 11 hours. Patients with varicose veins, edema, but without initial skin alterations or complications, were included. Measurements of skin laser Doppler (LDF) resting flux (RF) venoarteriolar response (VAR), ankle swelling (RAS), and edema were made within 12 hours before and within 3 hours after the flights. The resulting edema after the flights was evaluated with a composite edema score (analogue scale line). A group of 20 subjects was treated with HR (1 g/day, starting 2 days before the flight and 1 g for every 12 hours on day of travel). Another group of 18 subjects formed the control group. The length of the flights was between 11 and 13 hours; all seats were in coach class. Fifty patients were enrolled and 38 patients were evaluable at the end of the trial. The 2 groups (treatment and control) were comparable for age and sex distribution. The decrease in RF was significant in both groups with a higher flux at the end of the flight in the HR group (p<0.05). The venoarteriolar response was decreased at the end of the flights; the decrease was lower in the HR group (p<0.05). The increase in RAS and the edema score were significantly lower in the HR group. In conclusion HR is useful for reducing the level of microangiopathy and the increased capillary filtration and in controlling edema in patients with venous disease in long flights. The higher level of flux and VAR and the reduction in edema indicate a positive effect of HR on the microcirculation. This study confirms that HR prophylaxis is effective to control flight microangiopathy associated with edema.

Abstract
An 85-year-old man presented with bilateral leg edema and urinary incontinence. Abdominal examination revealed a severely distended bladder. Venous duplex of the legs demonstrated monophasic waveforms bilaterally, suggesting obstruction of proximal lower extremity veins. Relief of urinary obstruction was associated with the prompt return of normal respiratory variation of flow in the veins and improvement of leg swelling. Non-thrombotic obstruction of the proximal veins of the lower extremities by a severely enlarged urinary bladder is an infrequent yet potentially reversible cause of lower extremity edema. Subtle clues in the Doppler waveforms of an otherwise normal lower extremity venous duplex examination are crucial in establishing this diagnosis.

Abstract
Trophic leg ulcer is a major health problem affecting approximately 1-2% of the population, the incidence being higher in the elderly (70-80 years). It is a multifactorial condition, but the most common cause is chronic venous insufficiency. This can be attributed to reflux in the saphenous system and calf perforator vein incompetence. These were first described by Linton, the first intervention designed to correct perforator vein incompetence bearing his name. Today Linton's operation has been abandoned due to the large unaesthetic incision and great postoperative pain. Also, ulcer healing time is long (2 months) and recurrence rate is high. Currently a series of minimally invasive procedures are used to close these perforator veins, such as ultrasound-guided sclerotherapy. The advantages of these techniques are less discomfort to the patients, low rate of complications, short hospital stay.

Abstract
Balloon angioplasty (BA) is a treatment modality to correct vascular lesions in multiple sclerosis (MS) patients, who present with chronic cerebrospinal venous insufficiency (CCSVI). We hypothesized that BA clinical benefits stems in part from improvement in cardiovascular autonomic nervous system (ANS) function. We adopted the Transvascular Autonomic Modulation (TVAM), as a modified BA technique, with the objective of further enhancing ANS functional activities. TVAM involved dilation of multiple vascular beds, including IJVs, azygos and renal veins, and application of manual compression. Since the ANS regulates the function of the hypothalamus pituitary (HPA) axis, we examined TVAM effects on HPA axis in MS patients, and determined the relationship between ANS function and HPA activity. The adrenocorticotropic hormone (ACTH) and cortisol serum levels, systolic and diastolic blood pressure (BP), and heart rate variability (HRV) parameters were measured before and 24 h after TVAM procedure in 72 MS patients. Baseline ACTH and cortisol serum levels were lower than normal ranges in 18% and 25% MS patients respectively. The intervention resulted in significant reductions in both ACTH and cortisol (p<0.001), with a more marked ACTH reduction in males compared to females (p<0.001). Post-TVAM BP increased in patients who presented with baseline BP within lower limits of normal ranges, but decreased in patients with baseline BP above the normal ranges. In a univariate analysis, the changes (Δ) in ACTH serum levels correlated weakly, although significantly, with Δ in diastolic BP (r=-0.265, p=0.03), and Δ in cortisol serum levels correlated weakly, but significantly, with Δ in systolic BP (r=-0.283, p=0.01). The observed ACTH and cortisol reductions are counter to the stress-mediated increases in serum levels of these hormones, which are expected following an invasive procedure. The clinical implications of this unexpected response warrant further investigations.

Abstract
INTRODUCTION In the intersaphenous vein (ISV) there may take place the so-called "antegrade" or "paradoxical" reflux. This type of blood flow is revealed in a series of patients during muscular diastole and is a link of the pathogenesis of varicose disease, but has, as distinct from the "classical" reflux, an antegrade direction. An incompetent saphenopopliteal junction (SPJ) is a source of the antegrade diastolic blood flow (ADBF) through the ISV. Descriptions of possible variants of impaired blood flow through the ISV are fragmentary and their interpretations are controversial. Prevalence and pathogenesis of these disorders impairments have not yet been studied. MATERIAL AND METHODS A cross-sectional study: over 4 years three centres examined a total of 1,413 patients diagnosed with class C2-C6 varicose veins according the CEAP classification. All patients underwent ultrasound duplex scanning of lower limb veins. The ADBF was determined as a unidirectional antegrade blood flow with the duration of not more than 0.5 second, observed after the crus was relived of compression (in the diastole). Of the patients included into the study who had no varicose veins on the contralateral extremity with the ISV being spotted we sequentially selected 40 subjects including them into the Study Group for the analysis of blood flow and the diameter of the ISV in health. RESULTS Impairments of blood flow in the ISV were revealed in 61 (4.8%) of 1,265 extremities included into the study: the "classical" reflux in 9 (14.8%) limbs, ADBF was revealed in 37 (60.7%) limbs, a combination of the "classical" blood flow and ADBF - in 15 (24.6%) limbs. Hence, the patients were subdivided into three groups. Studying the nature of blood flow through the ISV in the control group on 40 lower limbs revealed no blood flow disorders. The mean ISV diameter amounted to 1.68 mm (ME=1 mm). The ISV diameter was considerably higher in all studied groups as compared with the control one (p<0.0001). The diameter of the ISV in its proximal portion averagely amounted to 4.48 mm (SD 1.337 mm, SE 0.171 mm). The diameter in the distal portion amounted to 5.39 mm (SD 1.725 mm, SE 0.221 mm).

Abstract
OBJECTIVES Analysis of the incidence of Venous Compression Syndrome (VCS) with full block of the flow of the internal jugular veins (IJVs) in patients with Multiple Sclerosis and Chronic cerebro-spinal venous insufficiency. METHODS We included 769 patients with MS and CCSVI (299 males, 470 females) and 210 controls without ms and ccsvi (92 males, 118 females). each subject was investigated by echo-color-doppler (ecd). morphological and hemodynamic ecd data were recorded by a computerized mem-net maps of epidemiological national observatory on ccsvi and they were analyzed by mem-net clinical analysis programs. RESULTS VCS of IJVs occurs in 240 subjects affected by CCSVI and MS (31% of total) and in 12 controls (6% of total). The differences between the two groups are statistical significant (X² = 36.64, p<0.0001). CONCLUSION Up to day there are no longitudinal studies that allow us to identify the WC of jugular and/or vertebral veins as etiology of a chronic neurodegenerative disease, but we note that Venous Compression Syndrome of IJVs is strongly associated with MS and CCSVI.

Abstract
The study was aimed at investigating alterations in the concentration of matrix metalloproteinases (MMP-1, MMP-9) and the tissue inhibitor of metalloproteinase-1 (TIMP-1), as well as the level of magnesium ions (Mg2+) as an indicator of connective tissue dysplasia (CTD) in patients presenting with lower limb varicose veins. The study included a total of 110 people. Of these, the Study Group comprised 90 patients with lower limb varicose veins of clinical class C2-C6 (according to the CEAP classification) and the Control Group was composed of 20 apparently healthy volunteers. Samples of peripheral blood were examined. The content of MMP-9, MMP-1 and TIMP-1 in blood serum was determined by means of the quantitative solid-phase immunoenzymatic assay. The concentration of Mg2+ was determined by the colorimetric method. We revealed a statistically significant interrelationship between the concentrations of matrix metalloproteinases and severity of varicose transformation of lower-limb veins, with the highest level of matrix metalloproteinases being observed in patients with cutaneous alterations and trophic ulcers. Determination of the level of matrix metalloproteinases and magnesium ions, characterizing connective tissue dysplasia, makes it possible to predict the development of lower limb chronic venous insufficiency and to evaluate the degree of its severity.

Abstract
The authors assessed efficacy and safety of the operation of plication of deep veins of lower extremities, pelvic veins, and the inferior vena cava as a method of preventing fatal pulmonary artery thromboembolism. A total of 48 patients were operated on. Of these, 23 patients belonged to traumatological-and-orthopaedical cohort, 3 to general surgical cohort, 4 to gynaecological, and 18 to vascular cohort (isolated deep vein thrombosis). The length of the floating head of the thrombus varied from 2 to 10 cm. The presence of a floating thrombus in traumatological, surgical and gynaecological patients, regardless of the length of the floating part was an absolute indication for thrombectomy and venous plication. Vascular patients were operated on in accordance with the National Guidelines (with the length of the thrombus floating portion of not less than 4 cm). In all cases, surgical management envisaged direct and indirect thrombectomy. Plication was always performed above the level of venotomy. It was shown that thrombectomy combined with plication of major veins is a reliable and safe method of prophylaxis, being in some cases the only possible method of preventing fatal pulmonary artery thromboembolism. The operation of plication makes it possible not to cancel a scheduled surgical intervention in patients with a detected floating thrombus of major veins. The operation of thrombectomy and plication above the level of the floating head of the thrombus may be considered an operation of choice in the conditions where there is no possibility to use endovascular methods of treatment (implantation of a cava filter, endovascular catheter thrombectomy), as well as in pregnant women. Restoration of the venous lumen occurs at safe terms spontaneously, not requiring repeat surgical intervention. Simultaneous plication of the vein does not complicate the course of the postoperative period of the main surgical intervention. Thrombectomy and plication do not lead to the development of severe chronic venous insufficiency.

Abstract
The present study was aimed at assessing initial results of hybrid operations in obstructive lesions of the iliac-femoral veins in patients with post-thrombotic disease (PTD). Hybrid operations [open endovenectomy from the common femoral vein (CFV) with creation of an arteriovenous fistula + stenting of iliac veins] were performed carried out in a total of eleven patients with PTD. Of these, there were 7 men and 4 women aged from 34 to 52 years (mean age - 42.8±7 years). All patients had severe-degree chronic venous insufficiency (CVI). The distribution of patients according to the CEAP classification was as follows: C4a - 2 patients, C4b - 4 patients, C5 - 4 subjects, C6 - 1 patient. The time having elapsed since a newly onset episode of acute iliac-femoral venous thrombosis varied from 2 to 12 years (averagely - 7.1±3.3 years). The degree of manifestation of PTD was determined by means of the Villalta-Pradoni scale before and 6 months after the operation. Instrumental methods of study included ultrasound duplex scanning (USDS), magnetic resonance and/or multispiral computed venography, and contrast-enhanced X-ray venography. The technical success of the procedure amounted to 91%. In one patient with occlusion of the common and external iliac veins we failed to perform recanalization and stenting. A further one patient developed in-stent and CFV thrombosis on the second postoperative day. An attempt of catheter thrombolysis turned out unsuccessful. There were no wound complications in the postoperative period. Neither was pulmonary artery thromboembolism registered. The dynamic control was carried out by means of USDS before discharge from hospital and at 1, 3 and 6 months after the intervention. The outcomes of hybrid operations after 6 months were followed up in five patients. Secondary patency rate of the stented iliac veins amounted to 100%. No relapses of trophic ulcers were observed. According to the Villalta-Prandoni scale the value of the median of the composite index decreased from 15 to 7 (p=0.012). The first experience with hybrid operations for obstructive lesions of veins of the iliac-femoral segment demonstrated their high efficacy and safety. Efficiency of the operation was confirmed by significant clinical improvement and good results of patency of the restored-repaired segments of veins.

Abstract
Chronic venous insufficiency and chronic venous ulcers represent an important medical problem, because of the high incidence and prevalence in the general population, and need to be considered as a lifelong degenerative condition, with socioeconomic consequences. Ulceration is a severe complication of the post-thrombotic syndrome, often precipitated by minor trauma. The rate of post-thrombotic syndrome varies between 20% and 100% of patients with deep vein thrombosis, mostly occurring within two years of an initial thrombotic event. This syndrome is difficult to treat, causes significant disability and reduces the quality of life. To date, there are no effective therapies of chronic venous ulcers and no definite strategies for identifying patients at risk for the development of ulceration. The role of adequate compression with elastic stockings is well recognized. Several systemic drugs have been tested for a possible effect on chronic venous ulcer healing, but none has been widely accepted as standard therapy in this setting. It has been suggested that extended oral anticoagulation should be investigated as a possible preventative measure. Waiting for the results in this field, an adequate management of anticoagulation in terms of anticoagulant intensity and duration should be recommended for the prevention of recurrent deep vein thrombosis, post-thrombotic syndrome and chronic venous ulcers.

Abstract
INTRODUCTION The effect of obesity on chronic venous disease has been known. The effect of body height has not been studied until now, although venous pressure is clearly influenced by hydrostatic pressure in the vertical position. METHODS We have examined 1026 lower extremities in 124 men and 392 women with suspected chronic venous disease. Their clinical condition was evaluated using CEAP classification. Duplex sonography was used to exclude deep venous occlusion and to evaluate any present reflux. Venous functions were evaluated based on venous pump performance during exercise and according to venous refilling time. RESULTS We confirmed the known, statistically highly significant relationship between age and weight, and severity of clinical condition and presence of reflux. We provided evidence of significant relationships between the clinical condition and plethysmographic parameters. We did not demonstrate a statistically significant relationship between body weight and clinical condition, venous refilling time after exercise and presence of reflux, and only a weak relationship with respect to the performance of venous muscle pump in the right lower extremities. CONCLUSION We did not demonstrate an effect of body height on the severity of chronic venous disease.

Abstract
The authors studied peculiarities of pelvic organs lesions in patients presenting with secondary small pelvic varicose veins (SPVV) induced by endured thrombosis of iliac veins. The study included a total of 70 patients after endured thrombosis of iliac veins verified by radiodiagnostic methods. The average duration of thrombosis amounted to 3.8 years. The patients were subdivided into two groups. The Study Group comprised 48 patients presenting with small pelvic varicose veins revealed by duplex scanning; the Control Group was composed of 22 patients with no varicose pelvic veins. It was determined that characteristic features of patients with secondary SPVV having developed after iliac veins thrombosis included chronic pelvic pain, dilatation of cavernous veins of the rectum, inguinal vein varicosity and varicose veins of the groin and anterior abdominal wall. Formation of secondary SPVV after endured iliac vein thrombosis leads to disorders of pelvic organs, similar to those in primary varicosity, but more often being functional. Endured iliac veins thrombosis in formation of secondary SPVV leads to urination impairments with prevalence of moderately pronounced symptomatology. Small pelvic organs dysfunction in women with secondary SPVV due to endured iliac veins thrombosis manifests itself in dyspareunia, leukorrhea, and dysmenorrhea.

Abstract
The authors assessed the effect of a micronized purified flavonoid fraction (MPFF) on the course of the postoperative period after endovenous thermal ablation (EVTA). The patients of the Study Group matching by the main studied parameters to the Control Group patients were given the MPFF according to the suggested regimen for 7 days. The obtained results were analysed by means of questionnaires (CIVIQ, VCSS, VAS) and ultrasound angioscanning. The obtained findings were statistically processed by means of the program Statistica 6.0 and reliability of the results was assessed with the help of the Student t-test. Patients of the both groups showed complete stable obliteration of the target veins. No statistically significant differences of the items of the questionnaires CIVIQ and VCSS at the beginning of the study and at the last examination were revealed, differences were noted on days 2-14 after EVTA and were not statistically significant (p>0.05). Phlebotrophic therapy in the postoperative period after EVTA helps to decrease phlebitic alterations in the coagulated vein, to improve motor activity and mental psychoemotional state of the patients.

Abstract
An analysis of the results of complex examination and treatment of 181 patients with varicose vein disease (according to CEAP classification C3-C6) was made. Patients were divided into 2 groups. The first group included 106 (58,6%) patients with venous clinical severity score C3 and the second group--75 (41,4%) patients with score C4-C6. An ultrasonic scintiangiography was used to determine the localization, intensity and length of blow-out in venous system of affected limb. The study found out 2 mechanisms of development of incompetent perforating veins. A superficial blood reflux influenced on the progress of venous insufficiency in 41 (38,7%) patients of the first group. The superficial and deep blood refluxes facilitated to development of the disease and were detected in 67 (89,4%) patients of the second group. It was stated, that there is a direct relation of perforating blood reflux rate with the level of intensity of superficial and deep blood reflux. The more expression of the refluxes took place, the more cases of incompetent perforating veins.

Abstract
Presented herein are the results of treatment of patients with chronic venous insufficiency and trophic ulcers of lower limbs on the background of varicose disease and postthrombophlebitic syndrome. The treatment consisted in removal of pathological deep vertical venous reflux by means of a modified method of dosed narrowing of the femoral vein according to P.G. Shvalb's technique [1]. The obtained outcomes confirmed the necessity of influencing the pathological vertical deep venous reflux in patients with severe forms of chronic venous insufficiency and pronounced retrograde shunt along deep veins.

Abstract
Despite a high level of the development of modern angiology and vascular surgery, the problem of chronic venous insufficiency (CVI) complicating the course of various venous diseases seems to have no tendency towards being solved, thus calling forth permanent search for optimization of methods of treatment and rehabilitation of patients presenting with the above-mentioned syndrome. The article presents a review of contemporary studies dedicated to the problem of correcting CVI. Special attention is paid to the endothelial state in CVI and possibilities of correcting endothelial dysfunction with the use of bioflavonoids, in particular, diosmin. Also presented herein are the results of an original experimental study dedicated to peculiarities of the endothelial functional state, endothelial dysfunction, and correction thereof on the background of the existing CVI.

Abstract
AIM Research of a starting point to debate about the possibility of identifying a unique sign of previous DVT. MATERIAL OF STUDY A retrospective study involving 202 outpatients with venous insufficiency of the lower limbs (CEAP classes C 4/6), classified according to the affected venous district. Patients positive for deep vein thrombosis (DVT) were subjected to Compression Ultra Sound test (CUS test) with measurement of the wall thickness at the point of formation of the thrombus and at fixed points of common femoral and popliteal veins used also in the patients with negative history of DVT RESULTS: Among total group, only 19 patients (9.40%) had an history of DVT. No one of them had a superficial incontinence. The measurement of wall thickness in positive DVT history patients (group A) resulted in an average value of 1.10 mm (s.d=0.06), while the average value obtained in negative DVT history (group B) was 0.55 mm (s.d.= 0.20). However, in 13 patients wall thickness was > 1mm (mean: 1.04 mm). The difference between the averages of group A and B was statistically significant (p <0.05). DISCUSSION In all positive DVT history patients and in 13 ones with negative history we found an increase in wall thickness, with a value > 1 mm. Can the wall thickening more than 1 mm be considered an indicator of previous DVT? Can it be considered a "marker" for thrombophilia status? CONCLUSIONS The usefulness of a sign of previous DVT (even if asymptomatic), detected during a routine Doppler ultrasound check of lower limbs, could be a warning bell to investigate thrombophilia status.

Abstract
In this article, the Author analyzes her own experience as a member of the IRB that approved a trial to determine the efficacy of a disobstruction procedure of extracranial veins by means of angioplasty in patients with multiple sclerosis (MS). The so-called "liberation therapy" was proposed by an Italian vascular surgeon, who theorized a condition called "chronic cerebrospinal venous insufficiency" (CCSVI) as playing a role in the pathogenesis of MS. This approval, given after an animated discussion amongst IRB members, lacked any solid scientific evidence of a causal relationship between CCSVI and MS, and was accepted despite the concerns about potential risks associated with the proposed therapy. Undoubtedly, considerable pressure was exerted on IRB by MS sufferers, who rushed off to get the surgery from the many clinics who offered liberation therapy.The remaining sense of bitter has raised a reflection on how to prevent similar future cases.

Abstract
AIM The aim of the present study was to prove the effectiveness, reliability and minimal invasiveness of cryosclerosis. METHODS A prospective non-randomized study had been performed. The study enrolled 96 patients; 48 patients were treated by cryosclerosis and the other 48 by conventional stripping. Every time high ligation and phlebectomy of varices were done, in 1 patient the incompentence of the small saphenous vein was treated also by cryosclerosis. During the follow-up visits the obliteration of the great saphenous saphenous vein (GSV) was investigated; as primary objective of the study, secondary outcome measures were the most frequent complications of the conventional surgery, postoperative pain and recovery. Color-Duplex scan of the operated lower extremity was performed into 30 patients of the study group. Additionally, the vein wall (unhandled and frozen) was analyzed by transmission electron microscope in one case. All of the involved patients were examined at a follow-up visit (7 days after surgery) and sent back a questionnaire (6-8 weeks after surgery). RESULTS Recanalization was observed only in 2 patients (success rate after 6 weeks: 93.3%). Thromboembolic events occurred only in the control group (1 patient, minor pulmonary embolism). Regarding mild wound healing disorder and lymphorrhea there were no significant differences between the groups. Concerning postoperative pain, bruising and recovery the cryosclerosis was found significantly favorable. The incidence of limb swelling after surgery was the same in each group. Temporary sensory abnormalities seem to be frequent in the study group, but the results show that the rate of permanent saphenous nerve injury is higher in the patients operated with the conventional method. The histological examination showed changes in the frozen vein wall. CONCLUSION Lacking long-term results, we can only consider that cryosclerosis allows the occlusion of the great saphenous vein, is minimal invasive and should be considered among endovenous procedures for treating GSV incompetence.
