Abstract The Brazilian Society of Angiology and Vascular Surgery has set up a committee to provide new evidence-based recommendations for patient care associated with chronic venous insufficiency. Topics were divided in five groups: 1. Classification, 2. Diagnosis, 3. Conservative or non-invasive treatment, 4. Invasive treatment and 5. Treatment of small vessels. This last series is closely related to the activities of Brazilian angiologists and vascular surgeons, who are heavily involved in the treatment of small superficial veins. These guidelines are intended to assist in clinical decision-making for attending physicians and health managers. The decision to follow a guideline recommendation should be made by the responsible physician on a case-by-case basis taking into account the patient's specific condition, as well as local resources, regulations, laws, and clinical practice recommendations.

Abstract Background The use of compression dressings after phlebectomy is based solely on clinical experience due to the lack of a unified set of definitive recommendations, which makes clinical practice extremely heterogeneous. Objectives To evaluate compression therapy with elastic stockings for 7 days after phlebectomy. Methods We randomly allocated 104 lower limbs with disease classified as C1 and C2 to 1 of 2 groups: an intervention group (64 limbs) – wearing elastic compression stockings for the first 7 days after phlebectomy; or a control group (40 limbs) – given conventional bandaging for 24 hours postoperatively. We compared clinical response by analyzing the evolution of symptoms, hematoma formation, and preoperative vs. postoperative limb volume. Results Pain (median 1.0 vs. 1.5, p=0.0320) and limb volume (mean 43.7 vs. 99.8, p=0.0071) were significantly improved in patients wearing elastic compression stockings for 7 days after phlebectomy compared with controls. Conclusions Use of elastic compression therapy for 7 days after phlebectomy was effective for improving pain and lower limb volume.

We have reported a case of a 36-year-old woman with flank and pelvic pain and hematuria. She had posterior nutcracker syndrome and pelvic varices involving one anterior and three posterior renal veins (including one major vein). We used a complete endovascular approach, which included stent implantation in the major posterior renal vein and left gonadal vein embolization. During a 12-month follow-up period, the patient had had no symptoms and good computed tomography results. Endovascular treatment represents a safe and successful option for patients with nutcracker syndrome and pelvic varices involving the anterior and posterior renal veins.

Abstract This systematic review was conducted in accordance with the 2009 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, including clinical studies in which one of the outcomes was semen parameter improvement after varicocele embolization using coils only. The objective of the review was to assess the evidence on the role of embolization using coils alone for semen parameter improvement in men with varicocele, since embolization using coils is the most cost-effective method of varicocele repair. Study quality was assessed using the methodological index for non-randomized studies (MINORS). Out of six retrospective and two prospective observational or comparative clinical studies involving 701 patients, semen concentration improved significantly in all five studies that assessed this parameter. Mean semen motility improved significantly in seven studies. The impact of embolization on semen density could not be analyzed.

Resumo A formação de linfocele, resultante da transecção dos canais linfáticos durante procedimentos cirúrgicos ou traumas, é relativamente comum, sendo relatada em aproximadamente 30% dos pós-operatórios de ressecção de linfonodos. Ela pode evoluir assintomática ou pode apresentar complicações, como dor, infecção secundária, compressão de vasos sanguíneos, a qual evolui para estase, trombose e edema. Seu tratamento ainda é de difícil consenso. Este artigo propõe descrever três casos em que o tratamento foi realizado a partir de ecoescleroterapia com polidocanol. Sua relevância está na escassez de relatos na literatura.

ResumoA escleroterapia com espuma guiada por ultrassom tem ganhado espaço no tratamento da insuficiência venosa crônica secundária a varizes dos membros inferiores. Trata-se de procedimento ambulatorial, de baixo custo e sem necessidade de afastamento das atividades habituais. Apresenta bons resultados clínicos, especialmente nos estágios mais avançados da doença. Quando bem aplicada, apresenta baixas taxas de complicações maiores. Porém, a técnica apresenta altas taxas de recanalização no médio e longo prazo, e seu mecanismo ainda não é totalmente compreendido. O presente artigo descreve um caso de fístula arteriovenosa em segmento de recanalização de veia safena magna, após escleroterapia com espuma guiada por ultrassom, e identificada por exame ultrassonográfico de vigilância pós-procedimento.

BACKGROUND: Ultrasound-guided foam sclerotherapy plays a major role in treatment of chronic venous insufficiency, providing clinical and hemodynamic improvement to patients undergoing treatment.OBJECTIVES: To examine the relationships between venous refilling time and impact of venous disease on quality of life and between changes in venous refilling time and improvement of symptoms after ultrasound-guided foam sclerotherapy for chronic venous insufficiency.METHODS: Thirty-two patients classified as C4, C5 or C6 answered a questionnaire on quality of life and symptoms and their venous filling time was measured using photoplethysmography before and 45 days after treatment of chronic venous insufficiency with ultrasound-guided foam sclerotherapy.RESULTS: Statistically significant improvements were observed in quality of life scores and in venous filling time and in the following symptoms: aching, heavy legs, restless legs, swelling, burning sensations, and throbbing (p

Abstract Pseudoaneurysm secondary to chronic pancreatitis is a rare complication, but one with a high mortality rate. It is etiologically associated with chronic pancreatitis, and most diagnoses are made after rupture, which manifests with clinical signs of acute hemorrhage. Computed tomography plays an important role in diagnosis, but digital subtraction angiography remains the gold-standard method for diagnostic confirmation and for treatment planning. This article describes two cases of pseudoaneurysm in patients with chronic alcoholic pancreatitis; one involving the splenic artery and the other the gastroduodenal artery, complicated by thoracic and abdominal bleeding respectively. Both were successfully treated, using minimally invasive endovascular methods to implant coils and stent-grafts.

ABSTRACT Objective: To compare the use of the radiofrequency thermoablation of the saphenous vein with the ligation technique, and complete removal of the saphenous vein, from the saphenofemoral junction to the ankle. Methods: A total of 49 patients with chronic venous disease in the Comprehensive Classification System for Chronic Venous Disorders (CEAP) classes 2 to 4 for clinical signs, etiology, anatomic distribution and pathophysiology, were assessed at baseline, after 4 weeks, and after 1 year. The parameters assessed were complications, period of absence from activities, Venous Clinical Severity Score (VCSS) and quality of life scores according to Aberdeen Varicose Veins Questionnaire (AVVQ). They were re-examined 1 and 3 years after treatment to evaluate recurrence rates. Results: The success rate per limb (p=0.540), VCSS (p=0.636), AVVQ (p=0.163), and clinical complications were similar in the two treatment groups. Nevertheless, the radiofrequency thermoablation group had significant shorter length of hospital stay (0.69±0.47) and absence from activities (8.62±4.53), p
