THA and TKA in patients with cardiovascular disease: What makes the risk of perioperative bleeding?

Insights

Patients with cardiac disease undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) face a higher risk of bleeding complications. These complications are more frequent after THA and TKA compared to other surgeries, even after adjusting for risk factors.

Area of Science:

  • Orthopedic Surgery
  • Cardiology
  • Thromboembolic Disease Management

Background:

  • Patients with cardiac disease have complex perioperative needs.
  • Thromboembolic disease poses significant risks in surgical patients.
  • Understanding complication rates after major joint replacement is crucial for patient safety.

Purpose of the Study:

  • To determine the incidence of bleeding and ischemic complications.
  • To compare complication rates after total hip arthroplasty (THA) and total knee arthroplasty (TKA) in cardiac patients.
  • To evaluate complication risks relative to other musculoskeletal surgeries.

Main Methods:

  • Retrospective study of 477 patients with cardiac disease undergoing THA or TKA between 2010-2013.
  • All patients received perioperative prevention of thromboembolic disease with low-molecular-weight heparins.
  • Data collection focused on perioperative bleeding and ischemic complications.

Main Results:

  • Overall complication rate was 11.6% (55/477 patients).
  • Bleeding complications occurred in 32 patients, ischemic in 19.
  • Bleeding complications were significantly more frequent after THA/TKA compared to other surgeries (p=0.003).

Conclusions:

  • Patients with cardiac disease undergoing THA and TKA have a significantly higher incidence of bleeding complications.
  • The risk of bleeding complications after THA/TKA is elevated compared to other musculoskeletal surgeries.
  • Bleeding complications after these procedures may not be easily predictable.

Cardiomyopathy VII: Pre and Post Operative Nursing Management

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Cardiac catheterization is an invasive diagnostic technique used to identify and evaluate structural and functional diseases of the heart and major blood vessels. This technique diagnoses congenital heart disease, coronary artery disease, valvular heart disease, and coronary spasms and assesses ventricular function. It helps guide treatment decisions, including the need for revascularization procedures like percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) and...

Disorders of Hemostasis01:24

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
