Background: This study is focused on Internal Iliac Artery (IIA) embolization in patients undergoing Endovascular Aneurysm Repair (EVAR). Our aims were: to establish the feasibility of the procedure; to assess the presence of endoleak (EL) and increase in the size of the sac at follow-up; to define the need for reintervention; and to evaluate mortality rate.
Methods: In this retrospective single-center study, EVAR-treated patients with an embolization of IIA were chosen. Coils and vascular plug were used as embolizing agents.
Results: A total of 49 participants were enrolled in the study (48 men and one woman) with a median age of 76 ± 12 years. Patients had no early EL in 87.75% of cases, 8.16% had type 1a EL, 2.04% type 1b EL, and 2.04% type 2 EL, with a comprehensive technical success of 95.91%. In the follow-up, at 1 month 72.22% remained without EL, at 6 months 70.97%, and at 1 year 81.48%. In the same period, the trend of type 1 EL was 5.56% (1 month), 3.23% (6 months), and 0% (1 year). For EL type 2: 22.22% at 1 month, 25.81% at 6 months, and 16.7% at 1 year. The overall mortality was 35.58% and the re-intervention rate was 16.33%.
Conclusions: IIA embolization is a feasible and safe procedure. The presence of EL is not superior to EVAR procedures that do not involve embolization.

Iliosacral screw osteosynthesis - state of the art.
Arch Orthop Trauma Surg

Department of Orthopedics and Traumatology, University Medical Center Mainz, Mainz, Germany.
Iliosacral screw osteosynthesis is a widely recognized technique for stabilizing unstable posterior pelvic ring injuries, offering notable advantages, including enhanced mechanical stability, minimal invasiveness, reduced blood loss, and lower infection rates. However, the procedure presents technical challenges due to the complex anatomy of the sacrum and the proximity of critical neurovascular structures. While conventional fluoroscopy remains the primary method for intraoperative guidance, precise preoperative planning using multiplanar reconstructions and three-dimensional volume rendering is crucial for ensuring accurate placement of iliosacral or transsacral screws.

Sarcoidosis is a systemic disease characterized by noncaseating granulomas involving any organ. Concurrent carcinoma breast with sarcoidosis is a rare occurrence. A 51-year-old female presented with right breast lump and was diagnosed with infiltrating ductal carcinoma with lymph nodal (LN) metastases (estrogen receptor, progesterone receptor positive, and HER2neu negative).

Background: Local relapse has not been eradicated even in the era of total mesorectum excision. Although various approaches have been attempted, R0 resection remains the only potentially curative treatment. PATIENT AND METHODS: A 45-year-old woman with a history of laparoscopic abdominoperineal resection was diagnosed with pelvic recurrence 7 months ago.

Introduction And Importance: Internal iliac artery aneurysms repair represents a life-threatening condition due to their anatomical position and the risk of rupture. Iliac branch devices are strongly recommended for anatomically suitable patients, but limited alternatives exist when their use is unsuitable. The use of custom-made fenestrated endografts is well documented in other aortic territories, however, their application for the treatment of internal iliac artery aneurysm remains limited.

Background: There is no consensus in the literature regarding the optimal treatment method for posterior pelvic ring injuries. This study aims to compare the radiologic and clinical outcomes, as well as complications of spinopelvic fixation (SPF) and iliosacral screw fixation (ISF) in patients with posterior pelvic ring injuries.
Methods: This retrospective study analyzed 54 patients (37 females, 17 males; mean age 38.
