Pulmonary embolism represents the most important complication of deep vein thrombosis, it is of particular concern to surgeons whose patients are prone to develop deep vein thrombosis in the immediate postoperative period. It is a significant source of hospital morbidity and mortality and despite an improved understanding of the pathogenesis diagnosis and management of pulmonary embolism, there continues to be frequent and significant mortality. Most current articles on venous thromboembolism begin with the statement that pulmonary embolism is a common problem and remains a significant cause of mortality in the western countries in spite of recent development in diagnostic and therapeutic modality. We evaluated clinical symptoms, diagnostic modality and therapeutic results of pulmonary embolism which was associated with deep vein thrombosis in 26 cases at Korea University Hospital between 1991 to 1996. Among 26 cases, 20 cases were male and 6 cases were female. The symptoms or signs were dyspnea(76.9%), tachypnea(65.4%), tachycardia(46.2%). The pulmonary perfusion scan was done in 18 cases and 16 cases were observed positive findings. The location of abnormal finding of perfusion scans were 8 both lung(44.4%), 5 right lung(27.7%), 3 left(16.7%). Treatment modalities were heparin, warfain in all cases, thromboembolectomy in 2 cases and insertion of IVC filter in 6 cases. Mortality was 11.5%. In conclusion, pulmonary embolism was not uncommon in Korea and its clinical feature were not greatly differ from literatures. In deep vein thrombosis, major concern and inspection are required to detect pulmonary embolism.

As the elderly population increases, occurrence of hip fractures has shown a rapid increase, and posttraumatic and postoperative venous thromboembolism can lead to fatal complications. Current prophylactic management includes mechanical and chemical prophylaxis. A 76-year-oldfemale, who was lost to follow-up after diagnosis of pulmonary thromboembolism four years ago, was admitted to our emergency room for a right intertrochanteric fracture. Before the operation, the thromboembolism recurred and was treated with anticoagulation medication. Bipolar hemiarthroplasty and fixation of the greater trochanter with a hook plate were performed 18 days after the trauma. Superficial femoral artery obstruction and venous thromboembolism occurred on the first day after the operation.

STUDY DESIGN: A prospective clinical study. PURPOSE: Our objective in the present study was twofold. First, we sought to evaluate the relationship between postoperative venous thromboembolism (VTE) development and concentration of D-dimer to determine the cutoff value in patients who underwent elective spinal surgery. Second, we identified the predictive risk factors for postoperative VTE. OVERVIEW OF LITERATURE: VTE affects the general health of patients and may even cause death. Since the complications of VTE are difficult to predict, the safest and most cost effective diagnostic method should be used in order to confirm a suspected VTE event after spinal surgery. METHODS: This study was performed on 97 patients who underwent elective spinal surgery. The D-dimer assay was carried out on the day before surgery, and on days 1, 3, and 10 following surgery. VTE occurrence and D-dimer levels were compared between the VTE and the control groups. RESULTS: Four patients (4.1%) were diagnosed with deep vein thrombosis and one patient (1%) was diagnosed with a pulmonary embolism. The optimum D-dimer cutoff value on day 3 following surgery in the VTE group was determined to be more than 2.1 microg/mL with a sensitivity of 100% and a specificity of 80.7%. Moreover, the duration of postoperative recumbency was a significant risk factor for the development of VTE in this study. CONCLUSIONS: We have demonstrated that postoperative D-dimer measurements in patients who underwent elective spinal surgery can provide a complementary diagnostic screening for VTE during the first week after surgery.
