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 […]

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.

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.

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 […]
