Controversies in Vascular Surgery.

There have been significant advances in vascular surgery in recent years. These advances include procedural techniques, choice of procedure, and application of nonoperative management. Endovascular techniques have expanded greatly over the past decade. As a result, for many clinical scenarios there is more than 1 option for management, which has given rise to controversies in the choice of best management. This article reviews current controversies in the management of carotid artery disease, abdominal aortic aneurysms, acute deep venous thrombosis, and inferior vena cava filter placement.

Venous insufficiency, lymphocutaneous fistula, and use of autologous blood.

Lymphocutaneous fistulas are an uncommon occurrence that can present after surgical intervention in lymphatic-rich areas. A spontaneous lymphatic leak can occur in conjunction with lymphedema or in the vicinity of venous stasis ulcers. However, spontaneous lymphocutaneous fistulas are extremely rare. Traditional treatments have included surgical ligation, negative pressure therapy, and embolization. We present the case of a lymphocutaneous fistula secondary to chronic venous stasis, which was treated via injection of autologous blood and subsequent thrombosis. In the present case report, we have demonstrated successful embolization of a lymphatic vessel via autologous blood injection, a nontraditional technique that, nonetheless, yielded positive and lasting results.

A unique case of bilateral lower extremity post-endovascular aneurysm repair claudication.

The majority of abdominal aortic aneurysms have been treated by endovascular aneurysm repair in the past decade. Common perioperative complications after this procedure are mostly related to vascular access and improper stent-graft placement. We present the first case of bilateral lower extremity claudication due to severe angulation of the graft-aorta interface, which may have been prevented by a more critical consideration of the patient's anatomy. Treatment required open explantation and repair of the abdominal aortic aneurysms which led to complete resolution of claudication. The results of this case highlight the importance of adherence to instructions for use guidelines.

Incoming residents' knot-tying and suturing skills: Are medical school boot camps sufficient?

INTRODUCTION: Many medical schools offer M4 boot camps to improve students' preparedness for surgical residencies. For three consecutive years, we investigated the impact of medical school boot camps on intern knot-tying and suturing skills when measured at the start of residency. METHODS: Forty-two interns completed questionnaires regarding their boot camp experiences. Their performance on knot-tying and suturing exercises was scored by three surgeons blinded to the questionnaire results. A comparison of these scores of interns with or without boot camp experiences was performed and statistical analysis applied. RESULTS: 26 of 42 (62%) interns reported boot camp training. There were no differences in scores between interns with or without a M4 boot camp experience for suturing [9.6(4.6) vs 9.8(4.1), p < 0.908], knot-tying [9.1(3.6) vs 8.4(4.1), p = 0.574], overall performance [2.0(0.6) vs 1.9(0.7), p = 0.424], and quality [2.0(0.6) vs 1.9(0.7), p = 0.665]) (mean(SD)). CONCLUSIONS: We could not demonstrate a statistically significant benefit in knot-tying and suturing skills of students who enrolled in M4 boot camp courses as measured at the start of surgical residency.
