Risk factors target in patients with post-thyroidectomy bleeding.

Area of Science:

• Endocrinology
• Surgical Oncology
• Vascular Surgery

Background:

• Post-thyroidectomy bleeding (PTB) is a significant and potentially life-threatening complication following thyroid surgery.
• Understanding the factors influencing PTB is crucial for improving patient outcomes and surgical safety.

Purpose of the Study:

• To identify and analyze the independent risk factors associated with post-thyroidectomy bleeding.
• To determine the common anatomical sources of bleeding during reexploration for PTB.

Main Methods:

• Retrospective analysis of 4449 consecutive patients undergoing thyroidectomy between February 2008 and September 2012.
• Statistical analysis to identify significant risk factors for PTB, including odds ratios and confidence intervals.
• Review of reexploration data to identify common bleeding sites.

Main Results:

• A total of 88 patients (2.0%) experienced clinically significant PTB.
• Six independent risk factors for PTB were identified: male gender, older age, tumor size greater than 3 cm, postoperative hypertension (systolic pressure > 150 mmHg), lymph node dissection, and Graves' disease.
• The most frequent sources of bleeding identified during reexploration were the infrahyoid muscles (30/88) and the area beside the laryngeal recurrent nerve (22/88).

Conclusions:

• Male gender, advanced age, larger tumor size, postoperative hypertension, lymph node dissection, and Graves' disease are significant independent risk factors for PTB.
• Identifying these risk factors can aid surgeons in anticipating and managing PTB.
• Knowledge of common bleeding sources, such as infrahyoid muscles and around the laryngeal recurrent nerve, is valuable for surgical planning and reexploration procedures.
