- Cateteres venosos totalmente implantáveis: histórico, técnica de implante e complicações(2017) ZERATI, Antonio Eduardo; WOLOSKER, Nelson; LUCCIA, Nelson de; PUECH-LEÃO, PedroAbstract Access to the venous system is of vital importance for diagnosis and treatment of patients with the most varied range of clinical conditions, whether for taking blood samples or for infusion of solutions. In 1616, Harvey described the circulatory system on the basis of studies in animals and 4 decades later Sir Christopher Wren conducted the first intravenous infusions in living beings. Since then there has been constant evolution in access technique and infusion devices. Of particular note is the creation of long-term catheters in the 1970s, particularly totally implantable devices, which revolutionized cancer treatment, increasing both safety and comfort for oncology patients. The objectives of this article are to review historical data on vascular access and discuss the implantation technique and the main complications associated with procedures for placement and use of totally implantable venous access devices.
bookPart Considerações gerais(2017) WOLOSKER, Nelson; ZERATI, Antonio Eduardo; FIORANELLI, AlexandrebookPart Etiologia, quadro clínico, diagnóstico, classificação e tratamento(2017) SAES, Glauco Fernandes; ZERATI, Antonio Eduardo- Endovascular Treatment of Penetrating Injury to the Vertebral Artery by a Stab Wound: Case Report and Literature Review(2017) LEIDERMAN, Dafne Braga Diamante; ZERATI, Antonio Eduardo; WOLOSKER, Nelson; MELO, Henry Augusto Hoffmann; SILVA, Erasmo Simao da; LUCCIA, Nelson DeBackground: We describe a unique case of a patient with penetration of the cervical region by a stab wound, who required emergency care for the controlled removal of the knife and for vertebral artery trauma (VAT) treatment. Although rare, VAT causes high morbidity and mortality. Methods: A patient admitted for emergency care was diagnosed with traumatic complete section of the vertebral artery by a knife and underwent removal of the knife under radioscopic supervision and vertebral artery embolization with coils. Results: The knife was removed successfully, the bleeding was controlled, and the patient did not present any sequelae. Conclusions: In the authors' experience, a patient in an emergent state due to VAT can be treated effectively and quickly with proximal embolization.
- Graduated Compression Stockings Does Not Decrease Walking Capacity and Muscle Oxygen Saturation during 6-Minute Walk Test in Intermittent Claudication Patients(2017) CAVALCANTE, Bruno Remigio; RITTI-DIAS, Raphael Mendes; SOARES, Antonio Henrique Germano; DOMINGUES, Wagner Jorge Ribeiro; SAES, Glauco Fernandes; DUARTE, Flavio Henrique; CRUZ, Aline de Paula da; WOLOSKER, Nelson; PUECH-LEAO, Pedro; CUCATO, Gabriel Grizzo; ZERATI, Antonio EduardoBackground: We analyze the effects of graduated compression stoking (GCS) on walking capacity and oxygen saturation in intermittent claudication (IC) patients. Methods: Eighteen patients with IC performed the 6-minute walking test in 2 conditions in random order: GCS or placebo sock. Onset claudication distance and total walking distance were obtained. The calf muscle oxygen saturation was continuously monitored before, during, and after 6-minute walk test. Comparisons of the walking capacity and StO(2) parameters between GCS and placebo conditions were analyzed by Wilcoxon rank-sum test. Results: The onset claudication distance (GCS: 120 +/- 99 meters vs. placebo: 150 +/- 126 meters; P= 0.798) and total walking distance (GCS: 330 +/- 108 meters vs. placebo: 324 +/- 60 meters; P= 0.130) were similar between conditions. There were no differences in StO(2) parameters between conditions (P > 0.05). Conclusions: GCS does not decrease walking performance and calf muscle oxygenation saturation during 6-minute walk test in patients with IC.
bookPart Tromboembolismo pulmonar(2017) ZERATI, Antonio Eduardo- Endovascular Treatment of Late Aortic Erosive Lesion by Pedicle Screw without Screw Removal: Case Report and Literature Review(2017) ZERATI, Antonio Eduardo; LEIDERMAN, Dafne Braga Diamante; TEIXEIRA, William Gemio Jacobsen; NARAZAKI, Douglas Kenji; CRISTANTE, Alexandre Fogaca; WOLOSKER, Nelson; LUCCIA, Nelson de; BARROS FILHO, Tarcisio Eloy PessoaBackground: Aortic lesions are uncommon complications in spine surgery, but potentially fatal, because they can cause massive bleeding and hemodynamic instability. We report the endovascular treatment of late aortic erosive lesion by pedicle screw without screw removal. Methods: A breast cancer patient had a pathological fracture on T10, with spinal cord compression, and a pseudoaneurysm of the aorta in contact with an anterolateral pedicle screw. Endovascular surgery corrected the aortic lesion and allowed decompression, a week later, by posterior arthrodesis (T7-L1), with screw maintenance. Results: There was no contrast leakage at thorax angiotomography in 2 years, and she died of meningeal carcinomatosis. Conclusion: Screw maintenance was safe in the endovascular treatment of aortic lesion by erosion.
- Leiomyosarcoma of the inferior vena cava: Survival rate following radical resection(2017) TEIXEIRA JR., Frederico Jose Ribeiro; COUTO NETTO, Sergio Dias do; PERINA, Andre Luis De Freitas; TORRICELLI, Fabio C. M.; TEIXEIRA, Luciana Ragazzo; ZERATI, Antonio Eduardo; FERREIRA, Fabio de Oliveira; AKAISHI, Eduardo Hiroshi; NAHAS, William Carlos; UTIYAMA, Edivaldo MassazoLeiomyosarcoma (LMS) of inferior vena cava (IVC) is a rare neoplasm affecting approximately 1/100,000 people. The prognosis is poor and potential curative intent occurs through challenging operations, such as vena cava resection, occasionally multivisceral when required, and vascular reconstruction. There are few retrospective series regarding this retroperitoneal neoplasm, and the aim of the present study was to discuss the experience at the Sao Paulo Cancer Institute and Clinics Hospital of University of Sao Paulo Medical School, Sao Paulo, Brazil. The current study is a retrospective review of 7 patients treated in the two tertiary hospitals between 2005 and 2013. Oncological and operative aspects were discussed, primarily regarding surgical aspects highlighting en bloc resection, vascular reconstruction, and the overall survival and recurrence rates. All the patients were treated with radical intent, 4 of whom underwent multivisceral resection, with the kidney being the most resected organ. The location of the IVC tumor was described using Kulaylat's description and the median tumor size was 10 cm. Vascular reconstruction was necessary in 4 patients. The overall survival rate at 3 and 5 years was 100, and 25%, respectively. The disease-free survival rate at 3 and 5 years was 57 and 20%, respectively. In conclusion, IVC LMS is a rare and severe retroperitoneal neoplasm, with multivisceral resections remaining a surgical challenge. The treatment requires numerous experienced surgeons and the impact of microscopic free margins remains unclear. Vascular reconstruction depends on several aspects regarding primarily the topography of the tumor.
