Unlabelled: In spite of the fact duplex Doppler ultrasonography is recognized as an scanning technique equivalent to other imaging methods for preoperative diagnostics of the lower extremity arteries, in many centres its use is limited to screening.
The Aim Of The Study: was to the determine usefulness of arterial duplex mapping for preoperative diagnostics in patients with peripheral artery occlusive disease (PAOD).
Material And Methods: In 2008-2009, 103 patients with PAOD symptoms (129 limbs) were examined in a prospective, non-randomized study. DUAM was performed in all limbs, DSA in 90, CT-angio in 29, and revascularisation procedures in 116 limbs.
Results: Problems with completing DUAM occurred in 10,1% of cases, including 1.5% of examinations of no diagnostic value. Consistency of DUAM and DSA results was found in 94.6% of cases, and consistency of DUAM results and the range of actually performed ranges was found in 97.8% of cases. Consistency of DUAM and CT-angio results was recorded in 68.0% of cases. The comparison between individual examinations and the actually performed procedures showed consistency of 96.5% for DUAM and 72.4% for CT-angio.
Conclusions: DUAM usefulness for detecting and defining lesions in lower extremity arteries is similar to that of DSA and CT-angio. This examination may be successfully used in preoperative diagnostics, particularly for intravascular procedures, which makes possible to reduce exposition to radiation and minimalize diagnostics costs.

This study investigated the prevalence and severity of lower urinary tract symptoms (LUTS) in children with spastic cerebral palsy (SCP) and evaluated the effect of selective dorsal rhizotomy (SDR) in alleviating these symptoms. The study also explored the correlation between postoperative LUTS improvement and intraoperative electrophysiological findings. Prospective data were collected from a consecutive cohort of 247 children with SCP who underwent SDR and were retrospectively analyzed.

Approximately 90% of glioblastoma recurrences occur in the peritumoral brain zone (PBZ), while the spatial heterogeneity of the PBZ is not well studied. In this study, two PBZ tissues and one tumor tissue sample are obtained from each patient via preoperative imaging. We assess the microenvironment and the characteristics of infiltrating immune/tumor cells using various techniques.

Many advocate adapting surgical technique based on preoperative CT staging as not all patients require complete mesocolic excision (CME) and D3 lymphadenectomy. We aimed to assess the sensitivity and specificity of preoperative CT scans in nodal staging and analyse whether inadequate CT staging could have influenced local recurrences.

Background: Enhanced recovery after surgery (ERAS) protocols have gained widespread acceptance as a means to enhance surgical outcomes. However, the intricate care required for kidney transplant recipients has not yet led to the establishment of a universally recognized and dependable ERAS protocol for kidney transplantation.
Objective: We devised a customized ERAS protocol to determine its effectiveness in improving surgical and postoperative outcomes among kidney transplant recipients.

Congenital heart disease (CHD) is a complex common defect in pediatric patients, and definitive treatment is usually cardiac surgery, especially for diseases with complex aetiology (ie, Critical CHD). While significant success has been reported due to improvement in diagnosis and treatment, the risk of mortality is still relatively higher than in the general population. Advances in surgical and post-surgical clinical management continue to increase survival in pediatric patients.
