CT-based analysis of posterior tibial slope in a Turkish population sample: A retrospective observational study.

Posterior tibial slope (PTS) is important for the success of high tibial osteotomy and unicondylar knee arthroplasty applications, as it provides anterior cruciate ligament function. In the literature, different studies have been carried out with various imaging methods to measure PTS in populations of different ethnic origins. In this study, it was aimed to detect PTS in the medial (MPTS) and lateral (LPTS) tibial condyles with computed tomography in a Turkish population sample and to compare the results between age groups (<65, ≥ 65), genders, sides, and literature data.

Diagnostically challenging rupture of pancreaticoduodenal artery aneurysm: A case report.

Splanchnic artery aneurysms are rare vascular lesions with a high risk of rupture regardless of their size. Symptoms may vary from simple abdominal pain or vomiting to morbid conditions like haemorrhagic shock; however, most aneurysms are asymptomatic and difficult to diagnose. In this study, it was aimed to present the case of a 56-year-old female with a ruptured pancreaticoduodenal artery aneurysm treated by coil embolization.

Methods: Single-phase head, neck, chest, and abdominal CT scans of adults performed in 64-slice CT in 2018 were included in this study. Radiation dose parameters of CT scans were obtained from the picture archiving and communication system of our hospital.

Endovascular Treatment of Critical Limb Ischemia in Buerger Disease (Thromboangiitis Obliterans) With Midterm Follow-Up: A Viable Option When Bypass Surgery Is Not Feasible.

Thromboangiitis obliterans (TAO) is an occlusive inflammatory disease affecting small- and medium-sized vessels that causes decrease in life quality and eventually limb loss. The only proven treatment method is smoking cessation, but it may be insufficient for limb salvage in patients with critical limb ischemia. In this single-center retrospective study, the feasibility and efficiency of endovascular treatment in TAO were evaluated.

Percutaneous endobiliary ablation of malignant biliary strictures with a novel temperature-controlled radiofrequency ablation device.

Purpose: We aimed to determine the safety and effectiveness of percutaneous endobiliary radiofrequency ablation of malignant biliary obstructions with a temperature-controlled radiofrequency ablation device.

Methods: In this single center retrospective study, a total of 62 consecutive patients with malignant biliary obstruction were evaluated. Thirty patients who underwent endobiliary radiofrequency ablation with metallic stent placement were in the study group and 32 patients who underwent only metallic stenting were in the control group.

An Unusual Method for Controlling Bile Leak from an Immature T-tube Fistula.

T-tubes have been used by surgeons for the decompression of the choledocus for over a hundred years. Errors in the operative technique and patient-related risk factors, such as immune comprehensive therapy, diabetes mellitus, steroid drug usage, T-tube morphology, T-tube material, and the T-tube extraction technique, are some of the factors that affect the risk of bile leak. In most cases, a surgical approach is required.
