Abstract：
UNASSIGNED: Although the rate of venous thromboembolism (VTE) after foot and ankle surgery is low, multiple factors influence risk for individual patients. Furthermore, there are no clear guidelines on which patients may benefit from chemical thromboprophylaxis. Our aim was to assess patients not treated with chemical thromboprophylaxis after foot and ankle surgery, and to report on their specific patient and surgical risk factors for VTE.
UNASSIGNED: This was a multicenter, prospective, national audit of patients undergoing foot and ankle surgery (including Achilles tendon ruptures) from 68 participating UK centers. The study was conducted between June 1, 2022, and November 30, 2022, with a further 3-month follow-up. Following data cleansing, 3309 patients were included who did not receive postoperative thromboprophylaxis.
UNASSIGNED: Most patients were elective cases (2589 patients, 78.24%) with ASA grade I or II (2679 patients, 80.96%), fully weightbearing postoperatively (2752 patients, 83.17%), and either without ankle splintage, or splinted in a plantigrade boot (2797 patients, 84.53%). The VTE rate was 0.30% overall (11 cases), with no VTE-related mortality. No single demographic, surgical, or postoperative factor was associated with reduced risk of VTE. However, patients who had elective or trauma surgery not involving the ankle, who were ASA grade I or II and who were weightbearing immediately postoperatively (without splinting or in a plantigrade boot) had a VTE rate of 0.05% (1 of 1819 patients), compared with 0.67% (10 of 1490 patients, P = .002).
UNASSIGNED: Patients not receiving chemical thromboprophylaxis had a low incidence of symptomatic VTE, although they do represent a curated group considered lower risk. Within this group we describe characteristics associated with a substantially lower risk of VTE. All patients should be assessed on an individual basis, and further work is required to substantiate our findings.

摘要：
■尽管足踝部手术后静脉血栓栓塞（VTE）的发生率很低，多因素影响个体患者的风险。此外，对于哪些患者可从化学血栓预防中获益,目前尚无明确的指南.我们的目的是评估足部和踝关节手术后未接受化学血栓预防治疗的患者，并报告他们的具体患者和手术危险因素。
■这是一个多中心，prospective,来自英国68个参与中心的接受足踝手术（包括跟腱断裂）的患者的国家审计。该研究于2022年6月1日至2022年11月30日进行，并进行了3个月的随访。数据清理后，3309例患者未接受术后血栓预防。
■大多数患者是择期病例（2589名患者，78.24%)与ASAI级或II级(2679例患者,80.96%），术后完全负重（2752例患者，83.17%），要么没有脚踝骨折，或固定在长靴中（2797名患者，84.53%）。总体VTE率为0.30％（11例），无VTE相关死亡率。没有单一的人口统计，外科,或术后因素与VTE风险降低相关.然而,接受非踝关节选择性手术或外伤手术的患者，ASA为I级或II级，术后立即负重的患者（无夹板或平足靴）的VTE率为0.05％（1819例患者中有1例），与0.67%(1490例患者中有10例，P=.002）。
■未接受化学血栓预防的患者有症状的VTE发生率较低，尽管它们确实代表了一个被认为风险较低的精心策划的群体。在该组中，我们描述了与VTE风险大大降低相关的特征。所有患者都应进行单独评估，需要进一步的工作来证实我们的发现。
