Inferior vena cava (IVC) filter placement is not indicated for thrombolytic interventional treatment for deep vein thrombosis (DVT). We analyzed the efficacy and feasibility of retrievable IVC filter placement for the preventive management of embolic shedding during catheter-directed thrombectomy (CDT) for DVT of lower extremity. ⋯ Our study findings suggest that retrieval IVC filter placement during interventional treatments of DVT of lower extremity such as thrombectomy of vein thrombus with or without stent insertion at compressed deep vein is favorable and effective for protecting against PE or lethal complications. We recommend carefully that before the management of DVT thrombus of lower extremity, retrieval IVC filter placement should be considered for preventing morbidity related with the PE.

Comparative Study
Dialysis Access Surgery: Does Anesthesia Type Affect Maturation and Complication Rates?
Creation of an arteriovenous fistula (AVF) is the preferred method of establishing long-term dialysis access. There are multiple anesthetic techniques used for patients undergoing this surgery including general endotracheal intubation, laryngeal mask airway, regional anesthesia with nerve blocks, and monitored anesthesia care with local infiltration. It is unclear what effect the method of anesthesia has on AVF creation success rate. It is our objective to determine if anesthesia type affects success of these surgeries defined by complication and maturation rates. ⋯ Our study shows that despite anesthesia type, outcomes in terms of maturation and complication rate are not statistically different in AVF creation surgeries. The use of monitored anesthesia care with local anesthesia may improve operative efficiency in terms of time in the operating room and in the recovery unit and therefore may be the preferred method of anesthesia. This recommendation may also parallel the preference to avoid general anesthesia in a patient population with more medical comorbidities. It is our conclusion that dialysis access surgery should therefore be performed under local anesthesia with monitored anesthesia care.

Review Case Reports
Leiomyosarcoma of the Inferior Vena Cava: A Case Series and Review of the Literature.
Leiomyosarcoma of the inferior vena cava (IVC) is an exceedingly rare smooth muscle sarcoma. Approximately 300 cases have been described in the literature, and further research is needed to understand the disease and guide its management. Surgery remains the only potential curative measure. ⋯ Surgical resection is the mainstay of treatment in patients with leiomyosarcoma of the IVC. A collaborative approach involving surgical oncologists and vascular surgeons ensures adequate resection with functional reconstruction to achieve the best patient outcomes.

Axillary Artery Injury Associated with Proximal Humeral Fractures: Review of Long-Term Vascular, Orthopedic, and Neurologic Outcomes.
Fracture and dislocation of the proximal humerus is common. It is associated with a number of vascular, neurologic, and orthopedic complications; these include brachial plexopathy and avascular necrosis (AVN) of the humeral head. These complications are rare but can potentially cause severe disability to patients; however, they remain poorly described in the literature. To describe vascular, orthopedic, and neurologic outcomes after axillary artery repair, in patients with proximal humeral fractures or dislocations. ⋯ There was an unusually high rate of injuries to the first part of the axillary artery. Close clinical observation is recommended for such patients. AVN of the humeral head and brachial plexopathy remain significant and debilitating complications.

This survey aims to explore trainees' perspectives on how Canadian vascular surgery training programs are using simulation in teaching and assessing technical skills through a cross-sectional national survey. ⋯ Surveyed vascular surgery trainees in Canada report that simulation is rarely used as a tool to assess baseline technical skills at the beginning of training. Less than half of surveyed trainees in vascular surgery programs in Canada report that simulation is being used for skills acquisition. Currently, in Canadian training programs, simulation is most commonly used to teach endovascular skills.
