We describe the case of a 59-year-old man who presented a mycotic aneurysm of the common right iliac artery due to Streptococcus agalactiae and developed an arteriovenous fistula within the inferior vena cava secondary to spontaneous rupture of the aneurysm. The clinical syndrome, helical computed tomographic, and angiographic findings are described and discussed.

Purpose: To describe an arthroscopic find of the posteromedial capsule lesion of the knee that we named "V" lesion, its treatment, and to present the results of 12 cases. Type of Study: Case Series. Methods: Twelve patients (11 males, 1 female) with "V" Lesion, combined with ACL (6) and with ACL and PCL (2). The mean age was 25 years (range, 18 to 34 years). All "V" Lesions were repaired by side to side knot with magnum wire #2 (Opus Medical) with outinside technique. The patients were assessed before surgery and at a mean follow up of 12.1 months (range 8 months to 2 years) by a physical examination, Lysholm II scores, knee range of motion and postoperative stress radiographs obtained with Telos device (Telos, Marburg, Germany). Results: Transoperative and postoperative physical examination revealed a reduction of the anterior and posterior drawer test and stress in valgus test: negative in all cases. In the patients with combined lesion (ACL, PCL) the stress in valgus continued positive after reconstruction and only became negative when the arthroscopic suture of the "V" Lesion was performed. On the Lysholm II knee scoring scale the score was excellent in 78% of the cases and good in 22% of the cases. The postoperative stress radiographs at six months revealed improvement of the medial, anterior and posterior instability. Conclusion: Treatment of the instability of the knee must be completed by repairing all lesions: anterior, posterior and medial. The side to side suture of the "V" Lesion improves the medial stability and can decrease the possibility of damage to ACL or PCL reconstruction. Level of Evidence: Level IV, therapeutic case series.
