    Background. Pancreatic adenocarcinoma is an aggressive cancer with a poor prognosis and increasing global incidence. Early diagnosis is challenging, as it is often detected at advanced stages. Imaging, particularly contrast-enhanced Multispiral Computed Tomography, plays a crucial role in diagnosing, assessing resectability, and monitoring treatment response. This study aimed to analyze Pancreatic adenocarcinoma characteristics, including tumor location, metastasis, resectability, and postoperative outcomes, using Multispiral Computed Tomography. Methods A retrospective review of 216 Pancreatic adenocarcinoma cases from 20222024 was conducted. All patients underwent bolus contrast-enhanced Multispiral Computed Tomography, and diagnoses were confirmed by histology. Key patient parameters analyzed included age, gender, tumor location, metastases, and surgical outcomes. Results The group comprised 50.9% women and 49.1% men. The majority of tumors were located in the pancreas head (72.2%), followed by the body (13.9%), tail (3.7%), and multiple sites (10.2%) (p<0.05). Metastases were observed in 50% of patients, with the liver being the most common site (p<0.05). Radical surgery was performed in 41 patients (19%), while 66 patients (30.5%) underwent palliative procedures. The mean life expectancy among deceased patients was without surgery 110 days, after radical resections 247 days, after palliative interventions 118 days. Conclusion Pancreatic adenocarcinoma remains a highly fatal disease, particularly at advanced stages. Metastasis significantly worsens prognosis, reducing survival rates. Tumor location influences prognosis, with body and tail tumors having better outcomes. Surgery improves survival, and early diagnosis is critical. Contrast-enhanced Computed Tomography is essential for evaluating pancreatic tumors but should be complemented with other diagnostic methods for enhanced accuracy.

    In this clinical case, stenosis of a renal artery of transplant was detected in time by angiography using dynamic Doppler ultrasound control. The chosen treatment method allowed the restoration of arterial patency and thus renal graft function in the shortest possible time and with minimal trauma. However, due to the high risk of restenosis in the plastic area, continuous dynamic ultrasound monitoring and monitoring of the patient's creatinine level are required. The purpose of this presentation is to present a case of early detection of a postoperative complication by Doppler ultrasound, which made it possible to prevent vascular dysfunction, often leading to loss of the renal graft. Materials and

    Methods. In this article, we report a case of timely detection of renal artery stenosis by ultrasound in a patient, followed by confirmation by angiography and restoration of renal artery and graft function by endovascular balloon angioplasty. All major hemodynamic changes in Doppler ultrasound parameters characteristic of renal artery stenosis are described in this article.

    Results. Dynamic Doppler ultrasound monitoring and angiography allowed early detection of the described complication of renal transplantation. The optimal choice of treatment tactics allowed the restoration of arterial patency and renal graft function in the shortest possible time, thus preventing graft rejection.

    Conclusion. Our clinical case demonstrates the importance of the monitor in the assessment of renal perfusion. The outcome of kidney transplantation largely depends on the successful resolution of these issues, which determines the relevance.
