Perforation of inferior vena cava (IVC) by filter struts ranges from 9% to 24%, and clinical sequelae and complications are unpredictable. The aim of this article was to report an unusual case of late complication of IVC filter that caused an IVC wall perforation and penetration of the filter's hooks in the aorta, which was treated by endovascular procedure. Molding strut tip by balloon angioplasty, its accommodation with a bare stent, and its coverage and protection with an endoprosthesis is probably the first technique reported so far in this situation.

Any obstacle in the contralateral artery has long been considered a high risk for carotid surgery. Here, we report the results of a monocentric, continuous, consecutive, prospective series and present a review of the literature. ⋯ In this series, and in a large review of literature, occlusion of the contralateral internal carotid artery increased the incidence of intolerance to clamping and thus the use of shunts but did not worsen postoperative morbidity and mortality. The presence of a stenosed contralateral carotid was not predictive of postoperative events. In our experience, the status of the contralateral carotid artery cannot be considered a high risk for carotid surgery.

During aortic surgery, the long-term patency of reimplanted intercostal arteries is unknown, limiting the relevance to preserve spinal cord vascularization. ⋯ Our experience indicates the long-term patency of reimplanted segmental artery, without any convincing evidence of its utility in preventing neurologic events during TAA and TAAA direct repair.

Transesophageal echocardiography (TEE) is routinely used in our Institution for monitoring correct positioning of thoracic aortic stent grafts. We present a case of successful endovascular repair of three discrete thoracic aortic aneurysms with Zenith TX2 endovascular stent grafts in an 82-year-old female patient. Our focus is on the increased value of TEE guidance because of the ability of partial stent deployment and manipulation during insertion.

Intraoperative vessel injuries can be serious enough to threaten the patient's survival. This study was performed to analyze the pattern, management, and outcome of intraoperative major vessel injuries and to clarify the risk factors leading to the injury. ⋯ Intraoperative vessel injury was most common in cancer surgery. The mortality and morbidity rate was higher in the postoperative late contact group. Early diagnosis and prompt contact to a vascular surgeon could reduce serious complications.
