Purpose: This study aims to assess and measure the origin of the superior vesical artery and its distance from the anterior trunk of the internal iliac artery, to which the anticancer drug is infused via double-balloon-occluded arterial infusion bladder-preserving therapy for locally invasive bladder cancer.
Material And Methods: The 160 pelvic sides of 80 patients were analyzed. Double-balloon catheters were bilaterally introduced into the contralateral superior gluteal artery via the internal iliac arteries using a bilateral transfemoral approach. The proximal balloon is placed at the internal iliac artery, proximally from superior gluteal artery bifurcation, whereas the distal balloon at the origin of the superior gluteal artery to isolate the anterior trunk of the internal iliac artery discharging to the targeted vesical arteries between the balloons. The side hole between the distal and proximal balloons was adjusted at the origin of the anterior trunk of the internal iliac artery to allow clear visualization of the angiographic flow into the bladder. After the distal and proximal balloons were inflated, three-dimensional rotational digital subtraction angiography was performed by simultaneous contrast injection from one extension tube connected to bilateral catheters. The distance (X) between the origins of anterior trunk of the internal iliac artery and superior vesical artery was measured on three-dimensional digital subtraction angiography images, and the origin of the inferior vesical artery was investigated.
Results: All superior vesical artery originated from anterior trunk of the internal iliac artery. The mean x was 7.2 mm (range 1.0-22.0 mm). All inferior vesical arterys branched from anterior trunk of the internal iliac artery or its branches.
Conclusions: Superior vesical artery commonly originates from the proximal portion of anterior trunk of the internal iliac artery close to superior gluteal artery bifurcation.

A 50-year-old female presented with a 10-day history of progressive swelling and pain in the left lower extremity, ultimately diagnosed with deep vein thrombosis (DVT) and May-Thurner Syndrome (MTS). Initial ultrasound indicated thrombosis involving the left external iliac, femoral, and popliteal veins, among others. Blood tests revealed normocytic anemia, but thrombophilia screening and other blood markers were normal.

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.
