Insights

A migrated hip prosthesis caused a slow bleed into the pelvis. Contrast computed tomography is recommended for diagnosing this rare complication after revision hip arthroplasty.

Area of Science:

  • Orthopedic Surgery
  • Vascular Surgery
  • Radiology

Background:

  • Revision hip arthroplasty can be complicated by prosthetic migration.
  • Acetabular component migration into the pelvis is a rare but serious complication.
  • Prosthetic migration can lead to vascular injury and hemorrhage.

Purpose of the Study:

  • To report a case of acetabular prosthesis migration into the pelvis.
  • To highlight the associated vascular injury (left external iliac artery bleed).
  • To emphasize the diagnostic utility of contrast-enhanced computed tomography (CT).

Main Methods:

  • Case report presentation.
  • Review of clinical course and imaging findings.
  • Discussion of diagnostic modalities.

Main Results:

  • A case of acetabular prosthesis migrating medially into the pelvis over four years post-revision hip arthroplasty.
  • Progressive displacement led to a slow bleed from the left external iliac artery.
  • Contrast-enhanced computed tomography successfully identified the migrated prosthesis and associated hemorrhage.

Conclusions:

  • Acetabular prosthesis migration into the pelvis can occur years after revision hip arthroplasty.
  • Vascular injury, such as external iliac artery bleeding, is a potential consequence.
  • Contrast-enhanced computed tomography is the preferred imaging modality for diagnosis.

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
