Risk factors for tissue expander complications: A retrospective cohort study of 1073 expanders
Summary
Low red blood cell count and larger expander volume increase tissue expander complication risks. Targeted prevention strategies are crucial for patients with these risk factors during tissue expansion procedures.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Surgical Complications
Background:
- Tissue expanders are widely used in reconstructive surgery.
- Complications can arise, impacting patient outcomes.
- Identifying risk factors is essential for prevention.
Purpose of the Study:
- To identify risk factors for tissue expander complications.
- To inform clinical strategies for prevention and management.
Main Methods:
- Retrospective cohort analysis of 539 patients and 1073 tissue expanders.
- Univariate and multivariate generalized estimating equations (GEE) analyses were performed.
- Risk factors were assessed for overall and specific complications.
Main Results:
- Overall complication rate was 9.60%, with expander rupture (4.75%) and skin ulceration (3.54%) being most common.
- Low preoperative RBC count and larger expander volume predicted overall complications.
- Low RBC count predicted rupture; older age, larger volume, and non-head/trunk location predicted skin ulceration.
Conclusions:
- Risk factors for tissue expander complications vary by complication type.
- Targeted preventive strategies are needed based on patient-specific risk factors.
- Clinical management should address preoperative RBC levels and expander volume.

01:24Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
01:26Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
