ABSTRACT

Abstract We report a case of inferior vena cava filter perforation immediately after filter implantation, recognized intraoperatively in a patient undergoing laparotomy for resection of locally advanced ovarian cancer. We describe an alternative approach with strut resection, less invasive than filter removal, enabling the device to be maintained and bleeding to be controlled.


Resumo Relatamos um caso de perfuração de veia cava inferior imediatamente após o implante de um filtro. A complicação foi reconhecida no intraoperatório de uma laparotomia para ressecção de um câncer de ovário localmente avançado. Descrevemos uma abordagem alternativa, menos invasiva do que a remoção do filtro, consistindo na ressecção das hastes do dispositivo. Essa abordagem permitiu a manutenção do filtro e o controle efetivo do sangramento.

ABSTRACT

ABSTRACT Objective To prospectively evaluate the perioperative safety, early complications and satisfaction of patients who underwent the implantation of central catheters peripherally inserted via basilic vein. Methods Thirty-five consecutive patients with active oncologic disease requiring chemotherapy were prospectively followed up after undergoing peripheral implantation of indwelling venous catheters, between November 2013 and June 2014. The procedures were performed in the operating room by the same team of three vascular surgeons. The primary endpoints assessed were early postoperative complications, occurring within 30 days after implantation. The evaluation of patient satisfaction was based on a specific questionnaire used in previous studies. Results In all cases, ultrasound-guided puncture of the basilic vein was feasible and the procedure successfully completed. Early complications included one case of basilic vein thrombophlebitis and one case of pocket infection that did not require device removal. Out of 35 patients interviewed, 33 (94.3%) would recommend the device to other patients. Conclusion Implanting brachial ports is a feasible option, with low intraoperative risk and similar rates of early postoperative complications when compared to the existing data of the conventional technique. The patients studied were satisfied with the device and would recommend the procedure to others.


RESUMO Objetivo Avaliar prospectivamente segurança perioperatória, complicações precoces e grau de satisfação de pacientes submetidos ao implante de cateteres centrais de inserção periférica pela veia basílica. Métodos Foram acompanhados prospectivamente e submetidos ao implante de cateteres de longa permanência de inserção periférica, entre novembro de 2013 e junho de 2014, 35 pacientes consecutivos com doença oncológica ativa necessitando de quimioterapia. Os procedimentos foram realizados em centro cirúrgico por uma mesma equipe composta por três cirurgiões vasculares. Os desfechos primários avaliados foram as complicações pós-operatórias precoces, ocorridas em até 30 dias após o implante. A avaliação do grau de satisfação foi realizada com base na aplicação de um questionário específico já utilizado em estudos prévios. Resultados Em todos os casos, a punção ecoguiada da veia basílica foi possível, e o procedimento foi concluído com sucesso. As complicações precoces observadas incluíram um caso de tromboflebite de basílica e um de infecção de bolsa, ambos tratados clinicamente sem necessidade de retirada do dispositivo. Dos 35 pacientes interrogados, 33 (94,3%) recomendariam o dispositivo para outras pessoas. Conclusão A implantação do port braquial é uma opção factível, com baixo risco intraoperatório e taxas semelhantes de complicações pós-operatórias imediatas quando comparada a dados já existentes da técnica convencional. Os pacientes estudados apresentaram-se satisfeitos com o dispositivo e recomendariam o procedimento para outras pessoas.

ABSTRACT

Acute limb ischemia can be potentially harmful to the limb and life threatening. Renal failure is a possible outcome associated with release of products of ischemic limb reperfusion. Some authors reported the benefit of performing angiography after embolectomy, even though iodine contrast is also nephrotoxic. We report a case of embolectomy on a patient with renal insufficiency in whom carbon dioxide was used as a substitute for iodine contrast.


A isquemia aguda de membro pode ser danosa para o membro e para a vida. A insuficiência renal é um desfecho possível associado à liberação dos produtos da reperfusão do membro isquêmico. Alguns autores relatam o benefício de realização de angiografia após embolectomia, apesar do contraste iodado também ser nefrotóxico. Relatamos um caso de embolectomia em uma paciente com insuficiência renal, em que o dióxido de carbono foi utilizado como substituto para o contraste iodado.

ABSTRACT

O avanço tecnológico da cirurgia endovascular no tratamento de aneurismas de aorta vem permitindo que uma maior quantidade de pacientes, antes considerados inaptos para essa abordagem, beneficie-se dessa modalidade terapêutica. Apesar da atual disponibilidade de endopróteses com alta conformabilidade, casos com anatomia desfavorável permanecem um desafio para os cirurgiões. Descrevemos um caso anatomicamente desfavorável, resolvido com sucesso pela técnica endovascular, utilizando-se uma manobra não convencional.


The advances in endovascular surgery for treatment of aortic aneurysms have allowed a greater number of patients, who were previously considered unsuitable for the approach, to benefit from this therapeutic modality. Despite the current availability of highly comfortable endografts, cases with unfavorable anatomy remain a challenge for surgeons. We report a case with difficult anatomy that was successfully managed using an unconventional endovascular technique.

ABSTRACT

OBJECTIVE: Isolated limb perfusion combined with melphalan is an accepted treatment for obtaining locoregional control in advanced melanoma of the extremities and other malignant neoplasias restricted to the limb. This study aims to examine the factors associated with toxicity caused by the regional method. We considered the technical aspects of severe complications associated with the procedure in an attempt to diminish the patient morbidity that occurs during the learning curve. METHODS: We conducted a retrospective analysis of the records of patients who underwent perfusion at the AC Camargo Hospital in São Paulo, Brazil between January 2000 and January 2009. The Wieberdink scale was applied to classify local toxicity and its relation to clinical and laboratory variables. RESULTS: Fifty-eight perfusions were performed in 55 patients. Most patients (86.2%) presented a toxicity level between I and III. Grade V toxicity was seen in five cases (8.6%), four of which occurred in the first 2 years. Creatine phosphokinase, an important predictive factor for toxicity, had an average value of 231.8 for toxicity grades I-III and 1286.2 for toxicity grades IV-V (p = 0.001). There was a relationship between the melphalan dose and toxicity, which was 77 mg (25 to 130 mg) for toxicity grades I-II and 93.5 mg (45 to 120 mg) for toxicity grades IV-V (p = 0.0204). CONCLUSION: It is possible to prevent the toxicity associated with melphalan by adjusting the dose according to the patient's body weight (especially for women and obese patients) and the creatine phosphokinase values in the postoperative period.

ABSTRACT

Introdução: A ressecção dos vasos carotídeos devido aparagangliomas é um procedimento de exceção. Pacientese Método: Os prontuários médicos de 39 pacientes foramrevisados retrospectivamente. Em seis casos, a ressecção daartéria carótida interna foi realizada para remoção completado tumor. Resultados: Havia três pacientes masculinos e trêsfemininos. A idade ao diagnóstico variava de 23 a 46 anos,com mediana de 28 anos. Em cinco pacientes, o tumor eraunilateral, sendo quatro à direita e um a esquerda. Um pacienteapresentava tumor bilateral. A avaliação pré-operatória foirealizada por tomografia computadorizada em todos os pacientese, em três casos, associou-se a angiografia. Em seis pacientes,não foi possível a dissecção através do plano subadventicial ea ressecção vascular foi necessária para remoção completado tumor. Optou-se pelo uso de um enxerto de safena ouprótese sem uso de shunts temporários. O tempo médio declampeamento dos vasos foi de 35 minutos. Apenas um pacienteapresentou complicação neurológica pós-operatória e estafoi temporária. Não houve qualquer caso de lesão isquêmicacerebral ou sequela permanente, bem como recorrências locaisou metástases a distância. Conclusão: Em alguns pacientes, oplano subadventicial estará obliterado pelo tumor. Nesta situação,a remoção completa do tumor pode exigir ressecção da artériacarótida interna. A nossa escolha, nestes casos, é a reconstruçãoimediata com o uso de um enxerto de veia safena e sem o uso deshunts temporários.


Introduction: Vascular resection due to paragangliomas is arare procedure. Patients and Method: The medical charts of39 patients were retrospectively reviewed. In six patients, theinternal carotid artery was resected for complete removal of thetumor. Result: There were three males and three females. Age atdiagnosis ranged from 23 to 46 years (median, 28 years). In fivepatients, there was a unilateral tumor, four on the right side andone on the left and one patient presented a bilateral tumor. Preoperativeevaluation was performed through CT scan in all patientsand angiography in three. Dissection through the subadventittialplane wasn?t possible in six patients and vascular resection wasnecessary for complete tumor removal. Saphenous vein grafts orprotheses were used in all patients, with a mean clamp time of 35minutes. One patient presented a transient neurologic sequela. Nopermanent deficit or ischemic stroke was recorded. Conclusion:The subadventitial plane may be obliterated in some patientsand complete tumor removal will mandate internal carotid arteryresection. Our choice in these cases is immediate reconstructionwith a saphenous vein or prothesis interposition between thevascular stumps.

ABSTRACT

INTRODUCTION: Venous malformations are the most frequent vascular malformation. Deep venous malformations are located in subcutaneous tissue or in the muscles. Percutaneous sclerotherapy is the treatment of choice, and the use of ethanol at low doses has not yet been described. OBJECTIVE: To analyze the results of treating Deep venous malformations patients with low doses of ethanol. METHODS: Thirty-nine patients treated between July 1995 and June 2007 were followed up prospectively over a median period of 18 months. Twenty-nine were female (74.4 percent) and 10 were male (25.6 percent), with ages ranging from 11 to 59 years (median of 24 years). All of the lesions affected limbs, and the main symptom reported was pain (97.4 percent). Each patient underwent fortnightly alcohol application sessions under local anesthesia on an outpatient basis. The lesions were classified into three groups according to size using nuclear magnetic resonance imaging: small, up to 3 cm (4 patients); medium, between 3 and 15 cm (27 patients); and large, greater than 15 cm (8 patients). RESULTS: The symptoms completely disappeared in 14 patients (35.9 percent) and improved in 24 (61.5 percent). The lesion size reduced to zero in 6 patients (15.4 percent) and decreased in 32 (82 percent). The median number of sessions was 7. There were no complications in 32 patients (82 percent), while 3 presented local paresthesia (7.7 percent), 2 superficial trombophlebites (5.1 percent), 1 skin ulcer (2.6 percent), and 1 case of hyperpigmentation (2.6 percent). CONCLUSION: Outpatient treatment for Deep venous malformations patients using ethanol at low doses was effective, with a low complication rate.

ABSTRACT

OBJETIVO: Quando há acometimento de artérias tronculares por neoplasias malignas e o tratamento cirúrgico é empregado para realização de ressecções tumoral e arterial, a reconstrução vascular deve ser imediata, para evitar a isquemia de tecidos nobres. O objetivo desse trabalho é analisar os resultados do tratamento de pacientes portadores de neoplasias malignas submetidos a ressecções tumoral e vascular associada à reconstrução arterial, avaliando a perviedade primária das reconstruções, as complicações arteriais e a sobrevida dos pacientes. MÉTODOS: Foram acompanhados 36 pacientes com neoplasias em regiões cervical, abdominal ou extremidades inferiores, operados eletivamente no período de setembro de 1997 a setembro de 2004 no Hospital do Câncer A.C.Camargo em São Paulo. Os pacientes foram divididos em três grupos de acordo com a localização das neoplasias: Cervical (14), Extremidade (13) e Abdome (9). Foram realizadas 38 reconstruções arteriais nos 36 pacientes. RESULTADOS: Houve cinco complicações arteriais, sendo duas precoces e três tardias. Entre as precoces, houve uma oclusão carotídea sintomática com seqüelas e uma rotura de enxerto femoral sem seqüelas. Entre as tardias, houve uma oclusão carotídea sintomática, uma oclusão de enxerto carotídeo-axilar e uma oclusão de ramo de enxerto aorto-bifemoral, todas sem sequelas. Não houve diferença entre os índices de perviedade arterial primária . Todos os óbitos (22) ocorreram devido à evolução da doença neoplásica. CONCLUSÕES: As reconstruções arteriais associadas à ressecção de neoplasias malignas em segmentos cervical, abdominal ou extremidades inferiores podem ser realizadas com baixos índices de morbi-mortalidade. Não houve diferença entre os índices de perviedade primária das reconstruções.

ABSTRACT

A braquiterapia de alta taxa de dose (BATD) associada à radioterapia externa (RT) representa uma boa opção para o tratamento do câncer da próstata, porém existem poucos relatos sobre sua toxidade. O nosso objetivo foi avaliar a toxicidade gastrointestinal (GI), genitourinária (GU) e sexual em 37 pacientes com adenocarcinoma de próstata; e conseguir toxicidade equivalente ou inferior à radioterapia conformada. Os pacientes receberam duas frações de BATD com doses de 7 a 8,5 Gy e 45 Gy de RT. A toxicidade foi avaliada pela classificação do Radiation Therapy Oncology Group e de Stone. As toxicidades GI e GU foram mais observadas em sua forma mais leve. A impotência sexual ocorreu na maioria dos pacientes. O tratamento apresentou toxicidade aceitável e semelhante à radioterapia conformada / High dose rate brachytherapy (HDR) in association with external beam radiotherapy (EBRT) is a good treatment option for prostate cancer, but there are few data about it’s toxicity. Our purpose was to analyze gastrointestinal (GI), genitourinary (GU) and sexual toxicities of 37 patients with prostate cancer and have a smaller or equal toxicity, compared with conformal radiotherapy. The patients were treated with two fractions of HDR with doses ranging from 7 Gy to 8.5 Gy, followed by 45 Gy of EBRT. The toxicity was scored according to the Radiation Therapy Oncology Group scales and the Stones classification. The GI and GU toxicities were mild in most cases. The sexual impotence was observed in most patients. The treatment presented acceptable toxicitiy, similars to conformal radiotherapy...

ABSTRACT

OBJETIVO: Estudar os resultados imediatos e tardios obtidos com a implantação de filtros de veia cava inferior em pacientes com trombose venosa profunda concomitante a neoplasia. MÉTODOS: Avaliamos retrospectivamente 50 pacientes com câncer e trombose venosa profunda associada submetidos a interrupção de veia cava inferior com filtros intraluminais definitivos. Foram estudados aspectos referentes à indicação do procedimento, à técnica de implante dos dispositivos, complicações precoces e tardias relacionadas à operação e à evolução dos pacientes. RESULTADOS: A indicação mais freqüente para o procedimento foi a impossibilidade de anticoagulação plena (80% ) e a via de acesso preferencial foi a punção da veia femoral, realizada em 86% dos pacientes. Não houve complicações relativas ao implante dos filtros. Durante a evolução ocorreram: um episódio de tromboembolia pulmonar não fatal e dois casos de oclusão da veia cava inferior; em um paciente foi demonstrada a presença de coágulo retido no dispositivo. Vinte pacientes (40%) faleceram devido à neoplasia.CONCLUSÃO: A interrupção da veia cava inferior com filtro endoluminal é um procedimento com baixo índice de complicações e eficaz na prevenção da embolia pulmonar nos pacientes com tromobose venosa profunda de membros inferiores portadores de câncer.

ABSTRACT

CONTEXTO: Os dispositivos totalmente implantáveis vêm sendo cada vez mais utilizados para quimioterapia de pacientes oncológicos, porém poucos são os estudos em nosso meio que analisam os resultados obtidos com a implantação e utilização desses cateteres. OBJETIVO: Estudar os resultados obtidos com a implantação de cateteres totalmente implantáveis em pacientes submetidos a quimioterapia. TIPO DO ESTUDO: Prospectivo. LOCAL: Hospital do Câncer A.C. Camargo, São Paulo, Brasil. MÉTODOS: Foram colocados 519 cateteres totalmente implantáveis em 500 pacientes a serem submetidos a regime de quimioterapia preferencialmente utilizando-se a veia jugular externa direita. Foram avaliadas as complicações precoces, as tardias e a evolução até a retirada do dispositivo, morte ou fim de tratamento. RESULTADOS: A análise prospectiva mostrou duração média dos cateteres de 353 dias. Em 427 (82,2%) cateteres não se observou nenhuma complicação. Entre as complicações precoces, observamos 15 hematomas de trajeto, oito tromboflebites de coto distal de veia jugular externa e uma infecção de bolsa de subcutâneo. Entre as complicações tardias, observamos 43 complicações infecciosas (0,23/1000 dias de uso de cateter), 11 obstruções (0,06/1000 dias de uso de cateter) e 14 tromboses venosas profundas (0,07/1000 dias de uso de cateter). Foram retirados 101 cateteres, 35 devido às complicações e 66 por final de tratamento. 240 pacientes foram a óbito com o cateter funcionante e 178 pacientes ainda o utilizavam para quimioterapia. CONCLUSAO: As baixas taxas de complicação obtidas nesse estudo confirmam a segurança e conveniência do uso dos acessos totalmente implantáveis em pacientes em regime prolongado de quimioterapia.

ABSTRACT

Introdução: Os dispositivos totalmente implantáveis vem sendo cada vez mais utilizados para quimioterapia de pacientes oncológicos porém poucos são os estudos em nosso meio que analisam os resultados obtidos com o implante e utilização desses cateteres. Material e Métodos: foram colocados 430 cateteres totalmente implantáveis em 415 pacientes a serem submetidos a regime de quimioterapia preferencialmente utilizando-se a veia jugular externa direita. Foram avaliadas as complicações precoces, as tardias e a evolução até a retidada do dispositivo, morte ou fim do tratamento. Resultados: a análise prospectiva mostrou uma duração média dos cateteres de 290 dias. Não se observou nenhuma complicação em 340 pacientes. Entre as complicações precoces observamos 11 hematomas de trajeto, 10 arritmias, 6 tromboflebites de coto distal de veia jugular externa e uma infecção de bolsa de subcutânea. Entre as complicações tardias, observamos 38 complicações infecciosas (0,3/1000 dias de uso de cateter), 10 obstruções (0,08/1000 dias de uso de cateter) e 13 tromboses venosas profundas (0,11/1000 dias de uso de cateter). Foram retirados 77 cateterers, 29 relacionados às complicações e 48 por final de tratamento. 172 pacientes foram a óbito com o cateter e 181 pacientes ainda o utilizavam para quimioterapia. Conclusão: as baixas taxas de complicação obtidas nesse estudo que implicaram em perda do cateter confirmam a segurança e conveniência do uso dos acessos totalmente implantáveis em pacientes em regime prolongado de quimioterapia.

ABSTRACT

PURPOSE: To analyze the results from using endovascular techniques to place long-term chemotherapy catheters when advancing the catheter using the external jugular vein is difficult due to obstructions or kinking. METHODS: Between July 1997 and August 2000, 320 long-term chemotherapy catheters were placed, and in 220 cases the external jugular vein was used as the primary venous approach. In 18 of these patients, correct positioning was not achieved and several endovascular techniques were then utilized to overcome these obstacles, including manipulation of a J-wire with a moveable core, venography, and the exchange wire technique. RESULTS: In 94.5 percent of the patients with difficulties in obtaining the correct positioning, we were able to advance the long-term catheter to the desired position with the assistance of endovascular techniques. CONCLUSIONS: Venography and endovascular guidance techniques are useful for the placement of long-term catheters in the external jugular vein

ABSTRACT

CONTEXT: Patients with malignant head and neck neoplasia may present simultaneous involvement of large vessels due to the growth of the tumoral mass. The therapeutic options are chemotherapy, radiotherapy, surgery or combined treatments. OBJECTIVE: To analyze the result of surgical treatment with carotid reconstruction in patients with advanced malignant head and neck neoplasia. DESIGN: Prospective. SETTING: Hospital do Câncer A.C. Camargo, Säo Paulo, Brazil. PARTICIPANTS: Eleven patients operated because of advanced malignant head and neck neoplasia that was involving the internal and/or common carotid artery. MAIN MEASUREMENTS: By means of clinical examination, outpatient follow-up and duplex scanning, we analyzed the patency of the carotid grafts, vascular and non-vascular complications, disease recurrence and survival of the patients. RESULTS: Six patients (54.5 percent) did not present any type of complication. There was one vascular complication represented by an occlusion of the carotid graft with a cerebrovascular stroke in one hemisphere. Non-vascular complications occurred in five patients (45.5 percent). During the follow-up, eight patients died (72.7 percent), of whom seven had loco-regional tumor recurrence and one had pulmonary and hepatic metastases (at an average of 9 months after the operation). Seven of these patients presented functioning grafts. The three patients still alive have no tumor recurrence and their grafts are functioning (an average of 9 months has passed since the operation). CONCLUSIONS: Patients with advanced malignant head and neck neoplasia involving the carotid artery that are treated surgically present a prognosis with reservations. When the internal and/or common carotid artery is resected en-bloc with the tumor, arterial reconstruction must be performed. The long saphenous vein is a suitable vascular substitute

ABSTRACT

Treatment of arterial traumatic intimal lesions is controversial due to its unknown natural history. Current therapeutical options include arterial reconstruction and clinical observation. The idea of using stents to correct intimal flaps is based on their use to correct dissections, flaps, and arterial irregularities after angioplasty. We report the successful treatment of a traumatic intimal flap of the superficial femoral artery, caused by gunshot trauma, with a Palmaz stent in the acute period. One year after the operation, a duplex scan revealed normal flow in the artery and complete exclusion of the intimal flap; distal pulses were palpable, and the patient was completely asymptomatic

CONTEXT: Many patients with intermittent claudication continue to be forwarded to the vascular surgeon for initial evaluation after arteriography has already been accomplished. OBJECTIVE: The main objective of this work was to analyze the usefulness and the need for this procedure. TYPE OF STUDY: Retrospective study. SETTING: The patients were divided into two groups: Group 1, with the arteriography already performed and Group 2 without the initial arteriography. PARTICIPANTS: One hundred patients with intermittent claudication were retrospectively studied. Other specialists had forwarded them for the first evaluation of intermittent claudication, without any previous treatment. MAIN MEASUREMENTS: All patients were treated clinically for at least a 6-month period. The total number of arteriographies performed in the two groups was compared and the need and usefulness of the initial arteriography (of Group 1) was also analyzed. RESULTS: The evolution was similar for both groups. The total number of arteriographies was significantly higher in Group 1 (Group 1 with 53 arteriographies vs. Group 2 with 7 arteriographies). For this group, it was found that arteriography was only useful in five cases (10 percent), because the surgeries were based on their findings. However, even in those cases, no need for arteriography was observed, as the procedure could have been performed at the time of surgical indication. CONCLUSION: There are no indications for arteriography in the early evaluation of patients with intermittent claudication, because it does not modify the initial therapy, independent of its result. In cases where surgical treatment is indicated, this procedure should only be performed prior to surgery
