Summary
Digital subtraction angiography (DSA) aids in diagnosing malignant renal tumors by precisely mapping cancer spread and kidney vessel involvement. This minimally invasive technique reduces radiation and contrast material, enabling effective preoperative assessment and therapeutic embolization.
Area of Science:
- Radiology
- Urology
- Oncology
Background:
- Renal tumors are predominantly malignant, with early detection challenging due to subtle clinical symptoms.
- Current treatments for kidney tumors remain suboptimal, necessitating improved diagnostic and therapeutic approaches.
Purpose of the Study:
- To evaluate the efficacy of digital subtraction angiography (DSA) in the preoperative diagnosis of renal tumors.
- To assess the role of DSA in defining tumor spread and renal vasculature involvement.
Main Methods:
- Digital subtraction angiography (DSA) was performed on 39 patients with renal tumors.
- Comparison with traditional intra-arterial renal vasography and cavography regarding radiation dose and contrast material usage.
Main Results:
- DSA demonstrated advantages in reduced irradiation doses and contrast material compared to conventional methods.
- The technique allowed for qualitative image processing and facilitated therapeutic interventions like embolization in 17 patients.
Conclusions:
- Digital subtraction angiography (DSA) is a valuable preoperative tool for assessing renal tumors.
- DSA offers improved diagnostic accuracy, reduced patient exposure, and enables concurrent therapeutic procedures such as embolization.
