Cardiovascular: balloon-tipped intravascular occlusion

Introduction

  • The placement of a balloon-tipped intravascular catheter into the internal or external carotid arteries has been used to allow immediate intravascular occlusion of the artery and to prevent retrograde flow from the cerebral arterial circle through a guttural pouch mycotic vascular defect   Guttural pouch: mycosis  .

Uses

  • Method of choice for mycotic lesions affecting the branches of the external carotid artery, particularly the internal maxillary artery.
  • Prevention of retrograde blood flow and hemorrhage from internal carotid artery mycotic lesions   Guttural pouch: mycosis  .

Advantages

  • Successful and safe.
  • Allows effective treatment of external carotid lesions.
  • Prevents retrograde blood flow from internal carotid lesions.

Disadvantages

  • More complicated to perform than ligation alone   Carotid artery: ligation  .
  • Additional expense of catheters.
  • Slightly higher risk of post-operative infection.
  • Occlusion of the external maxillary artery by a single balloon-tipped catheter has failed because it is impossible to control the direction of the catheter tip in the distal branches of the external carotid artery and it readily enters the superficial temporal artery rather than the maxillary artery.
  • Variations in the normal anatomic distribution of branches of the internal carotid artery can result in incorrect positioning of the catheter; occlusion of the wrong vessel; reflux of flow; and cerebellar injury.
