Compression syndromes of the popliteal neurovascular bundle due to Baker cyst

BackgroundThe purpose of this study was to perform a comprehensive search of the literature for all studies, case reports, and series describing Baker cyst compression of the neurovascular bundle in the popliteal fossa and index their findings according to the structures compressed.MethodCase reports and series obtained after a thorough MEDLINE search were indexed according to compressed structures. Patient demographics, main findings, method of diagnosis, cyst size, outcomes, and follow-up were recorded for each publication.ResultsSigns and symptoms related to popliteal vein and tibial nerve compression were the most frequent presentation of symptomatic Baker cysts, due to the anatomic vulnerability of these structures within the popliteal fossa and their relative sensitivity to compression. Patients with tibial nerve entrapment demonstrated gastrocnemius muscle atrophy, paresthesias, and pain. Those with popliteal vein compression experienced swelling, pain, and rarely, venous thromboembolism. Isolated arterial compression, presenting with intermittent claudication, is a rare occurrence because it is a relatively stiff-walled vessel, has a higher pressure, and is located deep in the popliteal fossa. Combinations of these compression syndromes are most frequently encountered in the context of cyst rupture and resulting compartment syndrome.ConclusionsBaker cyst is an important pathology for the differential diagnosis of popliteal neurovascular compression phenomena. It has a wide spectrum of presentation, therefore requiring accurate diagnosis for proper patient management. Because Baker cyst is by definition a chronic disorder, long-term follow-up is necessary to monitor patient recovery and prevent recurrence

Management of non-giant cell arteritis disease of the superficial temporal artery

Non-giant cell arteritis disease of the superficial temporal artery (STA) is rare, appearing only as case reports in the literature. There were nine patients with STA pathology. STA aneurysm (n = 1), pseudoaneurysm (n = 4), thrombosis (n = 1), and arteriovenous malformation (n = 3). Four patients had ligation and excision, three had percutaneous interventions and one had a combination of both. All patients had immediate technical success and eight of the nine total patients had follow-up. We present a variety of ways to approach these unusual pathologies with percutaneous and open techniques demonstrating very good early outcome

Pediatric venous thromboembolism in relation to adults

ObjectiveThis review was performed to analyze the current knowledge and controversies in the pathophysiology, diagnosis, treatment, and outcomes of pediatric venous thromboembolism (VTE) compared with adults.MethodsSearches of the MEDLINE database and manual searches of the references of selected articles were performed to select reports for their relevance and quality of information on the similarities and differences in pathophysiology, diagnosis, and treatment of VTE in children and adults.ResultsSymptomatic VTE incidence is reported at a rate of 0.07 in every 10,000 children, which is significantly lower than the rate in adults. Pulmonary emboli in adolescents are rarely fatal, unlike in adults. VTE recurrence is also much lower in children. Young age has been shown to be protective of VTE, whereas central venous catheters are very important in pediatric venous thrombosis. The incidence of postthrombotic syndrome varies from 20% to 65%, with mild symptoms in most children. Cerebral and visceral vein thrombosis may lead to severe morbidity and death. Some factors of thrombophilia have a significant effect in the pediatric population; however, its overall significance is controversial. Most data on VTE treatment are extrapolated from studies in adults. Children with acute VTE should be treated with anticoagulation therapy. Treatment duration depends on the nature of the thrombosis and previous VTE events.ConclusionsThere is a paucity of prospective randomized studies with data determining not only the effect of VTE but also the treatment options in children. Thrombophilia is a risk factor for pediatric VTE, but its significance has not been thoroughly investigated. Guidelines specific to children for antithrombotic therapy, prophylaxis, and optimal duration need re-evaluation and support by strong evidence

Ensaio clínico randomizado prospectivo comparando a ablação por radiofrequência e a retirada completa de veia safena em pacientes com doença venosa crônica leve à moderada com seguimento de 3 anos

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<000.1. Conclusion: Patients submitted to radiofrequency thermoablation had an occlusion rate, clinical recurrence and improvement in quality of life comparable to removal of the saphenous vein. However, these patients spent less time hospitalized and away from their daily activities during recovering
