Background

  • Potentially life-threatening
  • Can result from aneurysms, anastomosis rupture, or over-anticoagulation

Types

  • Aneursym (true)
    • Most are asymptomatic; rarely rupture
  • Pseudoaneurysm
    • Results from subcutaneous extravasation of blood from puncture sites
    • Bleeding from puncture site is usually controlled by digital pressure or subq suture
    • Consider vascular surgery consultation for continued bleeding or infection
    • Arterial Doppler US studies can identify the aneurysm or pseudoaneurysm

Clinical Features

Differential Diagnosis

AV Fistula Complications

Workup

  • Consider Doppler US

Management

  • Control bleeding w/ pressure applied to puncture site for 5-10min; observe for 1-2hr
