Excision of a permanent inferior vena cava filter with multiple vena caval perforations.
Perforation of an inferior vena cava filter by one the filter device hooks is a recognized possible complication of this device. We describe a case of surgical excision of a permanent inferior vena cava filter associated with multiple perforations of surrounding structures by each of the 6 hooks of the device. Structures affected include the third lumbar vertebral body, transverse mesocolon, the infrarenal aorta, the duodenum, and the psoas muscle. A thorough understanding of the filter design and adequate preoperative imaging were vital in planning the safe surgical excision of this device.

To determine whether the formation of an integrated vascular surgery residency (0 + 5) has negatively impacted the case volume and diversity of the vascular surgery fellows (5 + 2) and chief general surgeons at the same institution. ⋯ At our institution, the introduction of a 0 + 5 vascular residency has correlated with a modest drop (15%) in overall case volume for the 5 + 2 fellows, but the number of primary cases have actually increased slightly and they continue to meet or exceed Accreditation Council for Graduate Medical Education requirements and national 50th percentile rates. General surgery residents' vascular volumes, by contrast, have remained stable, and interest in vascular surgery by residents has increased. Our integrated vascular residents are projected to exceed the fellows' 50th percentile case volume and diversity targets during their residency experience.

Arterial complications among drug addicts are rare. Their appearance can engage the vital prognosis of the patient and present a major risk of amputation. The injection of products with high cellular toxicity induces septic necrosis of the arterial wall and adjacent tissues. It is frequently responsible for acute hemorrhage. The data in the literature concerning surgical treatment are discussed. The goal of our study was to analyze the immediate and midterm results of the surgical management of these arterial lesions. ⋯ Our study reveals the difficulty of the management of these arterial lesions. The local and general septic process is primarily responsible for early complications. Arterial restoration with extra-anatomic bypass makes it possible to be distant from the infection. This technique can be associated with a covering flap.

Extracorporeal membrane oxygenation (ECMO) provides continuous cardiopulmonary support on a long-term basis. It has been speculated that patients undergoing ECMO via femoral arterial cannulation are more likely to develop peripheral vascular complications. The purpose of this study was to evaluate the incidence of peripheral vascular complications in this group of patients and outline the modalities used for treatment. ⋯ Vascular complications occur in less then 20% of ECMO patients with the majority requiring femoral reconstruction. Development of vascular complications does not appear to increase risk of amputation or mortality. Among those patients who develop vascular complications, the most common indication for ECMO is cardiogenic shock.
