"低风险"人群初次人工关节置换术后的深静脉血栓 总被引:10,自引:0,他引:10
目的研究"低风险"人群在人工髋、膝关节置换术后深静脉血栓的发生情况。方法2003年2月至2005年4月,准备行选择性初次人工关节置换术的"低风险"患者136例,其中全髋关节置换术73例76髋,全膝关节置换术63例72膝,年龄46~84岁,平均68.5岁。具有深静脉血栓高危因素的患者排除在研究之外。患者术后均未采用任何方法预防深静脉血栓,于术后6~8天行静脉造影或根据临床表现急诊行静脉造影。怀疑肺栓塞的患者摄胸部X线片及CT加以确诊。结果全髋关节置换术73例76髋中,22髋(28.95%)发生深静脉血栓,其中近端栓塞14髋,远端栓塞8髋;全膝关节置换术63例72膝中,33膝(45.83%)发生深静脉血栓,其中9膝为近端栓塞,24膝为远端栓塞。全髋关节置换组与全膝关节置换组的深静脉血栓发生率比较,差异有统计学意义(!2=4.515,P<0.05);两组间近端血栓发生率比较,差异无统计学意义(!2=0.988,P>0.05);两组间远端血栓的发生率比较,差异有统计学意义(!2=11.348,P<0.05)。发生肺栓塞1例(0.74%)。临床症状对深静脉血栓的阳性预测值为52%。结论初次人工关节置换术后"低风险"人群深静脉血栓的发生率为37.16%,而临床表现并不能作为诊断深静脉血栓的可靠依据。临床上应建立起一套安全有效的方法降低深静脉血栓的发生。 相似文献

PurposeTo determine perioperative incidence and locations of deep vein thrombosis (DVT) in injured and uninjured lower extremities following isolated lower extremity fractures (ILEFs).MethodsRetrospective analysis of a prospectively collected data of a consecutive patient series with ILEFs who underwent surgical treatment between September 2014 and September 2017 was performed. Patients’ bilateral lower extremities were screened for DVT with duplex ultrasonography (DUS) before and after surgery. DVT occurrence was analyzed by location of DVT and fracture site. All patients received pharmacologic thromboprophylaxis while hospitalized. Data on demographics, time to surgery, time of DUS examinations, length of hospital stay and symptomatic pulmonary embolism (PE) was collected.Results1825 patients were included in the study. The incidence of symptomatic PE was 1.6%. All patients were screened with DUS of the bilateral lower extremities in a mean of 3.5 days (range: 0–18 days) after injury, and a mean of 3.6 days (range: 1–11 days) after surgery. Preoperative DUS detected DVT in 547 patients (30.0%), including 3.7% of patients with proximal DVT. 792 patients (43.4%) were found to have a DVT postoperatively, but only 6.2% of patients with proximal DVT. Proximal DVT was detected postoperatively of the represented fractures: 6.5% of the hip, 14.5% of the femoral shaft, 4.5% of the tibial plateau, 4.6% of the tibial shaft, 1.7% of the patellar, and 2.0% of the peri-ankle. Interestingly, the rate of DVT in an uninjured lower limb was significantly higher postoperatively compared to preoperatively (16.4% vs. 4.9%), however, only 0.2% of patients had proximal DVT.ConclusionsWhile the perioperative incidence of overall DVT is high following ILEFs, the majority were distal DVT, and the rate of symptomatic PE was low. Femoral shaft fractures were associated with the highest incidence for proximal DVT. The incidence was lower in more distal fractures. The majority of patients diagnosed with DVT postoperatively had already shown symptoms of DVT prior to surgery. DVT can occur in both the injured and uninjured leg, with an obviously higher incidence in the injured leg. The incidence of proximal DVT in an uninjured leg is rare. 相似文献

The purpose of this study was to determine whether those with lower extremity acute venous thrombosis have fever. During a recent 14.5-month period, 1847 patients undergoing lower extremity venous duplex scanning also had their oral temperature measured using a digital thermometer at the time of duplex examination. Patients were 57.8 +/- 17.3 years of age (range, 14 to 99). Temperature was 98.5 +/- 1.1 degrees F. Twenty-three patients had acute inferior vena cava thrombosis, 60 had acute iliac vein thrombosis, 138 had acute femoral venous thrombosis, and 131 had acute popliteal venous thrombosis. Calf vein thromboses were present in 102 patients, and 43 patients had superficial venous thrombosis. A total of 228 patients had acute lower extremity venous thrombosis in one or more of these venous segments. Temperature with acute lower extremity venous thrombosis was 98.7 +/- 1.05 degrees F versus 98.5 +/- 1.10 degrees F in those with no acute thrombosis. Although small, this temperature difference was statistically significant (P < 0.02). Acute deep venous thrombosis (DVT) was defined as acute popliteal or more proximal femoral, iliac, or vena cava thrombosis. The temperature for the 175 patients with acute DVT was 98.7 +/- 1.10 degrees F versus 98.5 +/- 1.10 degrees F for those without DVT (P < or = 0.035). There was no temperature that served to accurately differentiate those who did from those who did not have DVT. The frequency that patients with DVT had fever, defined as a temperature > or = 100 degrees F, was 9.1 per cent (16 of 175) with DVT versus 7.5 per cent (126 of 1678) without DVT (not significant). In the subgroup with a temperature > or = 101 degrees F, 4.6 per cent (8 of 175) with DVT had such a fever versus 3.4 per cent (57 of 1672) without DVT (not significant). Those undergoing venous duplex who were found to have acute lower extremity venous thrombosis, including acute DVT, had statistically higher temperatures, but such temperature differences were minimal. The incidence of fever, defined as a temperature > or = 100 degrees F or > or = 101 degrees F, was not different between those with and those without acute DVT. It appears that the presence of fever may not be a sensitive or specific indicator for the presence of underlying acute DVT. 相似文献

Objective: To describe a complication of placement of an inferior vena cava (IVC) filter in a man with paraplegia.Design: Case report.Participants/Methods: A 48-year-old man with T11 paraplegia secondary to an L1 burst fracture underwent thoracic spinal fusion. The postoperative course was complicated by deep vein thrombosis (DVT) of the right common femoral vein, which was treated with warfarin.Results: During rehabilitation, the hematocrit declined, and fluctuance was noted along the surgical site. Computed tomographic scan suggested a hematoma in the paraspinal and latissimus dorsi muscles. Warfarin was discontinued, and an IVC filter was placed. He subsequently developed severe leg pain, followed by hypotension, acute renal failure, and compartment syndrome in bilateral lower extremities requiring fasciotomies. Ultrasound and computed tomographic angiogram showed extensive bilateral lower extremity DVTs and pulmonary emboli. The diagnosis of cerulea dolens was made. Mechanical and pharmacological thrombectomy was aborted secondary to bleeding complications and hypotension. The patient died shortly after care was withdrawn at the family's request. The autopsy revealed multiple thrombi in IVC, bilateral pelvic and femoral veins, and left pulmonary artery embolus, consistent with phlegmasia cerulea dolens.Conclusions: Inferior vena cava filters may prevent pulmonary embolism but do not affect the underlying thrombotic process. An IVC filter should be recognized as a possible thrombogenic nidus in patients with spinal cord injury who have known DVT. 相似文献

PurposeCancer is a well-established risk factor for deep venous thrombosis (DVT). We sought to assess the incidence of DVT in pediatric cancer patients undergoing select surgical procedures at our institution and to identify additional factors associated with DVT development.MethodsWe performed a retrospective review of cancer patients who underwent select surgical procedures and developed a DVT within 30 days of their operation from 2000 to 2018 at our institution. Catheter-associated DVTs were excluded from this analysis. Major oncologic operations were selected.ResultsFrom 2000 to 2018, 3031 major oncologic operations were performed following which 14 symptomatic DVTs occurred, for an overall incidence of 0.46%. Procedures associated with post-operative DVT included: mass biopsy (7), pulmonary wedge resection (2), inguinal lymph node excision (1), colectomy (1), nephrectomy (1), lower extremity limb-sparing revision (1), and femur resection (1).ConclusionsOur data suggest that surgery does not put children with cancer at significant risk for DVT. Given the low incidence of perioperative DVT, routine pharmacologic prophylaxis for children with cancer undergoing surgery does not seem warranted.Level of Evidence: II 相似文献
