RESUMO

AIM: The purpose of the study was to compare the results of using compression knitwear and elastic bandaging in the postoperative period after endovasal laser coagulation in patients with varicose veins. PATIENTS AND METHODS: A total of forty 20-to-55-year-old women with a body mass index of ≤ 35 kg/m2 and CEAP class C2-C3 lower limb varicose veins were randomized into two numerically equal groups. The Study Group included those receiving postoperative compression on the operated leg with the help an elastic stocking, whereas in the Comparison Group compression was achieved by laying an elastic bandage. Both group women underwent laser coagulation of the great saphenous vein and removal of separate veins with the help of Mueller hooks. Efficacy of compression therapy was comparatively assessed based on the results of interviewing the patients prior to intervention and 1 month thereafter, as well as by the level of pain syndrome according to the visual analogue scale at 24 and 48 postoperative hours, by the time spent by the personnel for bandaging of the limb or putting on the compression stocking intraoperatively and at the first dressing, by the degree of lower limb oedema and dynamics of regression thereof, by the area of postoperative haematoma and its dynamics after 2, 7 days and at 1 month. Besides, we evaluated the findings of ultrasonographic angioscanning of lower limb veins at one month postoperatively. RESULTS: The obtained findings demonstrated that efficacy of using a medical compression stocking after the procedure of endovasal laser coagulation in women with varicose veins was comparable to that of elastic bandaging. By the incidence rate and area of extension of postoperative haematomas, degree of pain syndrome, patient-oriented assessment using the Chronic Venous Insufficiency Quality of Life Questionnaire (CIVIQ), condition of veins according to the findings of ultrasonographic angioscanning no significant differences were revealed between the two methods of elastic compression of the leg. However, using a medical stocking appeared to promote a statistically significant 1.4-1.6-fold reduction in the time spent for formation of elastic compression of the lower limb, as well as a decrease in the incidence rate and degree of local oedema of the lower limb in the postoperative period.

RESUMO

Mechanisms of the development of pain in chronic venous diseases (CVD), including pelvic congestion syndrome (PCS), are understudied. The existing hypotheses of the occurrence of venous pelvic pain (VVP) do not allow to answer the question why some patients have no pain syndrome while others have very pronounced pain despite the same morphofunctional changes in the pelvic veins. This review presents current hypotheses of the VPP development, data on some vasoactive neuropeptides (endothelin, calcitonin gene-related peptide, and substance P), their role in the modulation of vascular tone and sensation of pain, possible association between neurogenic inflammation and VPP and provides a rationale for studying the activity of these neurotransmitters in the treatment of PCS and pelvic pain.

RESUMO

OBJECTIVE: To study the results of endovenous laser obliteration (EVLO) for acute thrombophlebitis of saphenous veins of the lower extremities. MATERIAL AND METHODS: There were 57 patients (39 (68%) men and 18 (32%) women), mean age of patients was 54±20 years (range 34-74) with acute ascending thrombophlebitis of varicose superficial veins of the lower extremities (type I and II). EVLO of great saphenous vein was performed in 48 cases, small saphenous vein - in 9 patients. All EVLO procedures were carried out in outpatient fashion without hospitalization to the hospital. RESULTS: Complete obliteration of the target vein confirmed by ultrasound was observed in all patients the next day after surgery. Smooth course in long-term period (up to 1 year) was also noted in all patients. Recanalization of previously obliterated venous segment was absent. CONCLUSION: EVLO a safe and reliable alternative to traditional surgical approach for acute ascending thrombophlebitis. This technique is followed by reduced incidence of recurrent thrombophlebitis, no injuries typical for conventional surgery, minimal postoperative hospital-stay and pain syndrome. The procedure is characterized by minimal trauma, favorable cosmetic result and does not require hospitalization to specialized hospitals. EVLO for thrombophlebitis of varicose veins results high economic benefits due to minimally invasive simultaneous treatment of varicose veins and thrombophlebitis with small incidence of recurrences and complications.

RESUMO

RATIONALE: Oral bleeding is usually diagnosed after by referral to other department for the differential diagnosis of hematemesis or hemoptysis. If a patient presents with blood in the oral cavity with no obvious source, generally upper airway, pulmonary, or gastroesophageal lesions are considered likely bleeding foci. The tongue base is an unusual site for laryngopharyngeal varices and only a few cases have been reported. PATIENT CONCERNS: Although varix at the tongue base in patients with liver cirrhosis has been rarely described, physicians must consider variceal bleeding from the tongue base when presented with oral bleeding. In such cases, bleeding foci can be identified and controlled by laryngoscopy. We describe the case of a 42-year-old woman complaining of small amount of hemoptysis with variceal bleeding at the tongue base controlled by laryngoscopic excision and cauterization. DIAGNOSIS: A diagnosis of tongue base varix was made based on medical history, clinical manifestations, laryngoscopic findings and pathologic features for the patient. INTERVENTIONS: The successful laryngoscopic procedures were performed. OUTCOMES: The patient has shown no recurrent oral bleeding during follow-up. LESSONS: Variceal bleeding in the tongue base is likely to cause serious massive hemorrhage. We need to consider this possibility when presented with a patient with intraoral bleeding but no evidence of hemoptysis or hematemesis.

RESUMO

RATIONALE: Klippel-Trenaunay syndrome (KTS) is a congenital disorder characterized by cutaneous port wine capillary malformations, varicose veins with hemihypertrophy of soft tissue and bone.Pelvic and retroperitoneal vascular malformations have been described up to the 30% of patients with KTS while hemangiomas of the urinary tract have been reported in 6% PATIENT CONCERNS:: A 30-year-old man with KTS was referred to our center for primary erectile dysfunction (ED) associated with varicosities of unusual distribution and asymmetry of the lower limbs. Furthermore, he suffered from hypertension and autosomal dominant polycystic kidney disease.During penile prosthesis implantation, a significant intraoperative bleeding (1 liter) due to large scrotal venous malformations and profuse bleeding from both corpora was recorded. One month later, the day after the first prosthesis training session, the patient returned with swelling in the penoscrotal region. A large inguino-scrotal hematoma was drained. There was a complete bilateral dehiscence of corpora cavernosa with a spread venous bleeding in the scrotum. DIAGNOSES: CT scan showed hypertrophy of the right hypogastric artery with severe vascular malformations: the right pudendal artery was massively dilated with early visualization of venous drainage without evidence of arteriovenous fistulae; regular bulbocavernous capillary blush; right upper gluteus artery hypertrophic and dilated. Multiple twisting and aneurysms of the right internal pudenda artery were bleeding from multiple points. Cystoscopy showed a fistula between the proximal urethra and the penoscrotal dartos. Coagulation tests revealed the presence of factor XIII deficiency INTERVENTIONS:: The patient underwent several procedures including percutaneous scleroembolization of the internal pudendal arteries, removal of the penile implant, recombinant factor XIII (FXIII) administration, and cord blood platelet gel application. OUTCOMES: The patient was discharged after almost 3 months in hospital, hemodynamically stable. LESSONS: Experience regarding management of ED in KTS patient is limited and in case of concomitant factor XIII deficiency, the clinical scenario can be life-threatening. A multidisciplinary approach including a urologist, an interventional radiologist and a hematologist in our experience represented the key approach in case of severe bleeding following surgery for ED.

RESUMO

Orbital varix (or varicose) is an exceptional pathology with poor clinical sign. The blepharospasm can be a revealing cause. The long-term risk is optic atrophy and blindness. Magnetic resonance imaging is the best diagnostic tools. The rise of lesion dimensions by Valsalva maneuvers and prone position is characteristic. We report the observation of a 42-year-old young man, consulting for a blepharospasm of the left eye evolving for two years. Imaging investigations made the diagnosis of orbital varicose.

RESUMO

Chronic venous insufficiency (CVI) results from long-term venous hypertension in the legs caused by venous obstruction, venous valve incompetency, muscle pump dysfunction, or a combination of these. CVI occurs in 9.4% of men and 6.6% of women. It takes any of several forms, including leg pain and heaviness, leg edema that is worsened by prolonged standing and relieved by elevation, stasis dermatitis, skin fibrosis, skin ulcers, and varicose veins. If the patient history and/or physical examination results are suggestive of CVI, the diagnosis can be confirmed with duplex ultrasonography. The primary conservative treatment is use of compression stockings. Physical therapy and exercise programs often are recommended but little evidence supports their use. If a skin ulcer is present, appropriate wound care is indicated. Flavonoid drugs have been shown to improve venous function but none are approved for use in the United States. Diosmiplex, a flavonoid medical food product derived from oranges, is approved by the Food and Drug Administration for management of CVI and has shown some benefits. Patients with more severe manifestations of CVI should be referred to a vascular subspecialist for consideration of interventional therapies.

RESUMO

OBJECTIVES: Pelvic congestion syndrome is defined as chronic pelvic pain due to incompetent (dilated and refluxing) pelvic veins. The aim of this study was to investigate the prevalence of this condition by examining the prevalence of dilated ovarian and para-uterine veins in pre- and postmenopausal female patients, irrespective of their symptoms. We subsequently investigated how many women with dilated veins suffered from chronic pelvic pain. Additionally, we attempted to define diagnostic criteria that may allow for early identification of affected patients. METHODS: We reassessed 2384 abdomino-pelvic computed tomography scans performed on women at our institution. The maximal diameters of the ovarian and para-uterine veins were measured. Patients with a pathological process in the abdomen or pelvis affecting the veins were excluded. We considered ovarian vein dilation to be 6 mm or more in the axial plane. For patients that met these criteria, we performed a retrospective chart review to evaluate the clinical presentation and/or symptoms of these patients. RESULTS: Dilated pelvic veins were present in 293/2384 (12%) patients, 118/559 premenopausal (21%) and 175/1825 postmenopausal (10%). Chronic pelvic pain of unclear etiology had been documented prior to the CT in 54/293 (18%) women with dilated veins-2% of the whole study collective (54/2384); 8% of all premenopausal (44/559) and 0.5% of all postmenopausal (10/1825). It was often accompanied by urological symptoms such as hematuria, dysuria, and urinary frequency, in the absence of infection (p<0.05). We identified a strong correlation between the presence of dilated ovarian veins and chronic pelvic pain in premenopausal parous patients with hematuria. CONCLUSIONS: Pelvic congestion syndrome appears to be an underdiagnosed and undertreated disease. In our study, 8% of all premenopausal women had documented chronic pelvic pain of unclear etiology and dilated ovarian and pelvic veins on cross-sectional imaging studies. The features we identified in this study as most relevant should enable a faster identification of patients who could benefit from a specific treatment regimen for this condition.

RESUMO

A 74-year-old man presented to our hospital with recurrent lower gastrointestinal bleeding. His past medical history was remarkable for a duodenal papilla carcinoma and he underwent a pylorus-preserving pancreaticoduodenectomy 4 years before. During diagnostic work-up a severe portal vein stenosis after surgery and multiple dilated intramural jejunal varices, which formed as collateral pathways could be detected. Based on these findings, the recurrent haemorrhages were considered to be due to repeated rupturing and bleeding of jejunal varices. Therapeutically, the portal vein stenosis was treated with endovascular stent placement leading to a reduction in prestenotic portal pressure. During follow-up no further episodes of gastrointestinal bleeding were observed. Bleeding from jejunal varices is a very rare cause of gastrointestinal haemorrhages and represents a diagnostic and therapeutic challenge. However, it should be considered in differential diagnosis of obscure recurrent gastrointestinal haemorrhages in patients with a history of hepato-pancreato-biliary surgery.

RESUMO

A 78-year-old woman presented with melaenic stool and severe anaemia 4 years after a pancreaticoduodenectomy for adenocarcinoma of the pancreas. Initial workup revealed haemorrhage from the choledochojejunostomy site. Despite multiple endoscopic clips to the region, bleeding reoccurred multiple times over a period of several months. Due to ongoing haemorrhage, her case was urgently presented at the hospital's multidisciplinary hepatobiliary conference. The contrast-enhanced abdominal CT revealed severe stenosis of the extrahepatic portal vein and large afferent jejunal varices at the choledochojejunostomy, suspected as the cause of her persistent bleed. The recommendation was a percutaneous transhepatic approach for stenting of the portal vein stenosis that resulted in rapid decompression of the jejunal varices and control of her haemorrhage.

RESUMO

Cerebral developmental venous anomalies (DVAs) are the most frequently encountered cerebral vascular malformation. Most are asymptomatic and incidentally detected. Here we present a case of DVA associated with venous varix presented with chronic headache. A 50-year-old woman presented with right hemicranial headache since 6 months. There was no neurological deficit. MRI showed a well-defined oval T2 hyperintense, T1 isointense extra-axial lesion in the right parietal region showing intense homogeneous enhancement. Prominent vascular flow void was extending from the lesion up to the deep parietal white matter. Subtle thin linear areas of blooming noted in the parietal white matter converging towards the vascular flow void. The venous sac is in communication with the cortical vein draining to the superior sagittal sinus. These MRI findings favoured a diagnosis of DVA in the right parietal lobe with prominent draining vein forming a cortical venous varix. The patient was managed conservatively with symptomatic treatment for headache.

RESUMO

OBJECTIVE: To reach consensus on which complications of varicose vein treatments physicians consider major or minor, in order to standardize the informed consent procedure and improve shared decision-making. METHODS: Using the e-Delphi method, expert physicians from 10 countries were asked to rate complications as "major" or "minor" on a 5-point Likert scale. Reference articles from a Cochrane review on varicose veins were used to compose the list of complications. RESULTS: Participating experts reached consensus on 12 major complications: allergic reaction, cellulitis requiring intravenous antibiotics/intensive care, wound infection requiring debridement, hemorrhage requiring blood transfusion/surgical intervention, pulmonary embolism, skin necrosis requiring surgery, arteriovenous fistula requiring repair, deep venous thrombosis, lymphocele, thermal injury, transient ischemic attack/stroke, and permanent discoloration. CONCLUSION: An international consensus was reached about what physicians consider to be major complications of varicose vein treatments. This consensus may assist in standardizing the information physicians discuss with patients prior to varicose vein treatment.

RESUMO

OBJECTIVE: We aimed to evaluate the efficacy of liquid or foam sclerotherapy of varicose veins using venous clinical severity scores and possible complications. METHODS: A total of 318 patients (268 females, 50 males) who were treated with liquid or foam sclerotherapy between January 2012 and December 2012 were included in this study. RESULTS: Skin necrosis was observed in only 6 patients (1. 8%), thrombophlebitis in 10 patients (3. 1%), and hyperpigmentation in 18 patients (5. 6%) in this study group. The mean venous clinical severity score was calculated as: pain score, 1. 23 ± 0.88; varicose vein score,1.85 ± 0. 8; edema score, 0.64 ± 0.77). Pain and edema decreased at the control examination, 1 month after completion of sclerotherapy sessions. Varicose veins completely disappeared after sclerotherapy. While the decrease in edema in the foam sclerotherapy group was significantly less (P<0.001), the decline in pain showed an increasing trend (P=0.069). While skin necrosis did not develop after foam sclerotherapy, rates of pigmentation and local thrombophlebitis were similar (P>0.05). CONCLUSION: In conclusion, we observed that both sclerotherapy methods are effective with a low rate of complications, alleviating the complaints of patients with small varicose veins, and providing considerable improvement in venous clinical severity scores.

RESUMO

The authors examined the effect of the presence of undifferentiated connective tissue dysplasia (UCTD) on the clinical course of lower-limb varicose veins (LLVV) and acute varicothrombophlebitis (AVTP) in patients after the Troyanov-Trendelenburg operation. We carried out a prospective comparative study of the remote results during three years after the Troyanov-Trendelenburg operation in a total of 132 patients suffering from AVTP. The Study Group included 67 patients found to have more than four phenotypic traits of UCTD, thus suggesting the presence of UCTD. The Comparison Group consisted of 65 patients with no signs of UCTD. During three-year follow up, relapses of AVTP were diagnosed in 22 (32.8%) patients of the Study Group and in 5 (7.7%) patients of the Comparison Group (p<0.01). In four (6.0%) patients with UCTD, the thrombus propagated to the perforating veins of the crus, new danger of pulmonary embolism arose, and emergency phlebectomy was required. Thrombosis of the femoral vein was revealed in eight (11.9%) patients of the Study Group, and being free-floating in two (3.0%) of them, it was the cause of pulmonary embolism. They were subjected to plication of the external iliac vein. No thromboses of deep veins were revealed in the Comparison Group patients. Phlebectomy was performed in 57 (85.1%) patients of the Study Group and in 14 (21.5%) patients of the Comparison Group (p<0.01) due to remaining vertical and horizontal pathological venous reflux. Fifty-one (78.5%) patients of the Comparison Group six months after the Troyanov-Trendelenburg operation were found to have spontaneous restoration of the functional competence of the valvular apparatus of the perforating veins with elimination of the horizontal venous reflux, which predetermined regression of clinical manifestations of varicose veins, with no phlebectomy required. A conclusion drawn is that the clinical course of LLVV on the background of UCTD after the Troyanov-Trendelenburg operation is distinguished by predisposition to progression of chronic venous insufficiency and is characterised by a relapsing pattern of AVTP. Therefore, surgical policy, as well as medicamentous treatment after disconnection of the saphenofemoral junction in patients with AVTP should be decided upon with due regard for the phenotypic signs characterising UCTD.
