ABSTRACT Giant splenic artery aneurysm is a rare condition that represents an eminent life threatening for the patient, requiring, therefore, urgent surgical correction. A 61-year-old woman, former smoker, hypertensive, hypercholesterolemic and multipara sought our service because of a large tumor in the mesogastrium, which was an abdominal ultrasound finding. Despite the size of the tumor, the patient was asymptomatic. The angiotomography and the magnetic resonance image of the abdomen were suggestive of giant splenic artery aneurysm with more than 10cm […]

ABSTRACTObjectiveTo 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 […]

Endovascular revascularization of TASC C and D femoropopliteal occlusive disease using carbon dioxide as contrast

Cynthia de Almeida Mendes, Marcelo Passos Teivelis, Sergio Kuzniec, Juliana Maria Fukuda, Nelson Wolosker

DOI: 10.1590/S1679-45082016AO3661

ABSTRACTObjectiveTo analyze the results of ten angioplasties of TASC C and D femoropopliteal lesions using CO2 as primary contrast in patients with no formal contraindication to iodine, aiming to decrease allergic reactions and potential nephrotoxicity in high-risk patients.Methods We describe the results of ten angioplasties of TASC C and D femoropopliteal lesions using CO2 as primary contrast in patients with high risk for open revascularization and no formal contraindication to iodine. We analyzed feasibility of the procedures, complications, quality of […]

Carbon dioxide as a substitute for iodine contrast in arteriography during embolectomy

Nelson Wolosker, Marcelo Passos Teivelis, Cynthia de Almeida Mendes, Kenji Nishinari, Mariângela de Freitas Ribeiro, Sergio Kuzniec

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.

Combined use of GORE TAG® and Gore Exculder® endografts for treatment of abdominal aortic aneurysm with severe angulation

Mariana Krutman, Cynthia de Almeida Mendes, Flavio Henrique Duarte, Kenji Nishinari, Nelson Wolosker

DOI: 10.1590/S1679-45082014RC2788

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.

DOI: 10.1590/s1679-45082014gs3029

Objective To describe and analyze the results of a public-private partnership between the Ministry of Health and a private hospital in a project of assistance and scientific research in the field of endovascular surgery.Methods:The flows, costs and clinical outcomes of patients treated in a the public-private partnership between April 2012 and July 2013 were analyzed. All patients underwent surgery and stayed at least one day at the intensive care unit of the private hospital. They also participated in a research […]

Cystic adventitial disease of the popliteal artery: an infrequent cause of intermittent claudication

Paulo Kauffman, Sergio Kuzniec, Roberto Sacilotto, Marcelo Passos Teivelis, Nelson Wolosker, Adriano Tachibana

DOI: 10.1590/s1679-45082014rc2818

Intermittent claudication is frequently associated with atherosclerotic disease, but differential diagnosis must be sought in patients with no traditional risk factors. Cystic adventitial disease, of unknown etiology, most frequently affects the popliteal artery, and occasionally presents as intermittent claudication. We report a case of this disease and the surgical treatment, and discuss some aspects related to etiopathogenesis, diagnosis and treatment of this condition.

DOI: 10.1590/S1679-45082014AO2844

ObjectiveThis retrospective study evaluated the results of sclerotherapy with low doses of ethanol for treatment of head and neck venous malformations.MethodsWe treated 51 patients, 37 females. Median age was 23 years. Patients were treated with percutaneous intralesional injection of alcohol every two weeks and followed up prospectively for a median period of 18 months. Most lesions affected the face and cosmetic disfigurement was the most frequent complaint.ResultsWe performed a median of 7 sessions of sclerotherapy. Complete resolution or improvement was […]
