Selective arterial embolization in renal tumors.

F Frasson, C Fugazzola, G Bianchi

    Radiologia Clinica
    |January 1, 1978

    Summary

    Selective arterial embolization using Gelfoam facilitates nephrectomy for hypernephroma, reducing bleeding and improving tumor separation. This procedure is also effective for managing bleeding in inoperable cases, with limited long-term impact on tumor growth.

    Area of Science:

    • Interventional Radiology
    • Urologic Oncology

    Background:

    • Hypernephroma (renal cell carcinoma) presents significant surgical challenges.
    • Preoperative embolization is explored to improve surgical outcomes.

    Purpose of the Study:

    • To evaluate the efficacy of selective arterial embolization with Gelfoam in hypernephroma cases.
    • To assess its utility as a preoperative procedure and for managing inoperable tumors.

    Main Methods:

    • Selective arterial embolization using Gelfoam was performed in 45 hypernephroma patients.
    • The technique was used preoperatively in 33 cases and for palliation in 12 inoperable cases.

    Main Results:

    • Preoperative embolization facilitated nephrectomy in 97% of cases, with reduced operative bleeding (97%) and easier tissue separation (82%).

  • Embolization was effective in managing bleeding for inoperable patients.
  • Angiographic follow-up indicated limited long-term efficacy on tumor growth due to revascularization.
  • No severe complications were observed, apart from transient renal failure in some patients.

    • Conclusions:

    • Selective arterial embolization with Gelfoam is a valuable preoperative adjunct for hypernephroma, enhancing surgical safety and efficiency.
    • It provides effective palliative management for bleeding in inoperable hypernephroma.
    • The procedure demonstrates a good safety profile, with transient renal failure as the main complication.
