Summary
Bovine pericardial patches (BPP) are a durable option for arterial reconstruction in infected fields, showing a low recurrence of infection and revision rates. This study suggests BPPs are a viable alternative to autologous vein patches.
Area of Science:
- Vascular Surgery
- Biomaterials Science
- Infectious Disease Management
Background:
- Bovine pericardial patches (BPP) are utilized in arterial reconstruction, yet their efficacy in infected surgical sites remains under-investigated.
- Limited data exists on the infection resistance of BPP compared to traditional autologous vein grafts.
Purpose of the Study:
- To evaluate the hypothesis that BPPs offer a comparable alternative to autologous vein patches in infected arterial fields.
- To assess the durability and infection resistance of BPPs in patients undergoing removal of infected grafts.
Main Methods:
- A retrospective review of 51 arteriotomies repaired with BPP in 48 patients following infected polytetrafluoroethylene graft removal.
- Patient data were analyzed for outcomes including mortality, patch rupture, need for secondary reconstruction, and recurrent infection over a mean follow-up of 2.1 years.
Main Results:
- Fifty out of fifty-one BPPs remained functional without recurrent infection, rupture, or revision.
- One instance of acute popliteal arteriotomy rupture occurred, necessitating amputation.
- Eight patients died during follow-up from causes unrelated to the BPP repair.
Conclusions:
- Bovine pericardial patches demonstrate durability and effectiveness in arterial reconstruction after infected graft explantation.
- BPPs represent a reliable alternative to saphenous vein grafts in challenging, infected surgical scenarios.

01:22Pericarditis I: Introduction
Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...
01:17Pericarditis III: Medical Management
The primary objectives of managing pericarditis are to determine the underlying cause, provide effective therapy for treatment and symptom relief, and promptly detect signs and symptoms of cardiac tamponade. The following outlines the essential aspects of medical management for pericarditis:ObjectivesDetermine the Cause: Identifying the underlying cause of pericarditis is crucial for targeted treatment. Causes include viral infections, autoimmune diseases, post-cardiac injury syndrome, and...
01:19Pericarditis II: Clinical Features and Diagnostic Tests
Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...
01:25Pericarditis IV: Nursing Management
Pericarditis, an inflammation of the pericardium, necessitates diligent nursing management to ensure effective patient care and recovery. The initial step in managing pericarditis is a comprehensive patient medical assessment.The patient reports chest pain aggravated by breathing, coughing, and swallowing, which worsens when lying supine. The pain often improves when sitting up and leaning forward. Additional symptoms may include fever, malaise, and, in severe cases, signs of heart failure.
