概括
手术前的足底静脉 (SV) 直径大于6.75毫米,预测在全关节整形术 (THA) 后的双边深静脉血栓症 (DVT). 这一发现有助于识别患有肺血栓塞栓症 (PTE) 风险较高的患者.
科学领域:
- 血管外科 血管外科
- 整形外科手术 整形外科手术
- 放射学 放射学是一门学科.
背景情况:
- 双边下肢深静脉血栓瘤 (DVT) 与单边DVT相比,具有更高的肺血栓栓塞 (PTE) 和死亡风险.
- 手术前的足底静脉 (SV) 直径是术后DVT的公认预测指标.
- 鉴定VTE的风险因素对于患者管理至关重要.
研究的目的:
- 确定手术前底静脉 (SV) 直径的切割值作为VTE发展的风险因素.
- 调查SV直径与关节整形术 (THA) 后双边DVT发生的相关性.
主要方法:
- 一项回顾性研究包括274名接受单边THA治疗的患者.
- 进行了手术前和手术后的下肢静脉超声波.
- 患者被分为非DVT,单侧DVT (Uni-DVT) 和双侧DVT (Bi-DVT) 组,以比较手术前的SV最大直径.
主要成果:
- 手术后的DVT发生在22.6%的患者中 (44个DVT,18个DVT).
- 与非DVT组 (6.41±1.79 mm) 相比,Bi-DVT组 (8.06±2.26 mm) 的平均SV最大直径显著更大 (P=0.001).
- 术前SV最大直径的6.75mm的切割值预测了Bi-DVT,具有77.8%的灵敏度和60.4%的特异性 (AUC=0.728).
结论:
- 术前超声波检测最大SV直径为6.75mm或更大,与THA后双边DVT的风险增加有关.
- 这种测量可以作为一种有价值的预测指标,用于识别患有双边DVT和随后PTE风险较高的患者.

Venous Thrombosis I: Introduction
Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...
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...
Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
