“…To our knowledge, only five small open studies have evaluated a prophylactic method in Asian patients. 18,[31][32][33][34] These studies were small in size and the beneficial effect of treatment was in general not statistically significant, but all showed that prophylaxis could reduce the rate of venous thromboembolism to some extent. Although these data should be confirmed in larger well-conducted multicenter studies, we believe that there is no reason why the benefit of thromboprophylaxis, well documented in the West, 4 should not also be achieved in Asian patients.…”

“…In contrast, the prevalence of VTE is traditionally thought to be low in Asia and the use of thromboprophylaxis remains controversial [3][4][5][6][7][8][9][10][11][12][13][14][15]. However, several cases of fatal PE following orthopedic surgery have been reported in Japanese patients not receiving thromboprophylaxis [16][17][18][19][20][21][22][23].…”

Background: In Asia, the prevalence of postoperative venous thromboembolism (VTE) is traditionally thought to be low and the routine use of thromboprophylaxis remains controversial. Methods: We performed an exhaustive literature search for published studies on VTE in Asia. Predefined data were extracted from individual studies: country involved, number of patients, type of patient population, type, duration and dose regimens of treatments, if any, method used to detect deep-vein thrombosis (DVT) and pulmonary embolism (PE), and duration of follow-up. The main endpoints were the incidences of systematically detected DVT, and symptomatic DVT or PE. Overall adjusted percentages and 95% confidence intervals (CI) were calculated. Results: In clinical studies in patients not receiving thromboprophylaxis, the adjusted incidence of total DVT was 13% (95% CI: 10% to 16%) in general surgery, 16% (95% CI: 13% to 20%) after total hip replacement, 50% (95% CI: 44% to 55%) after total knee replacement and 18% (95% CI: 12% to 24%) in hip fracture surgery. The adjusted incidence of PE was 1% (95% CI: 0% to 2%) in general surgery and 1.4% (95% CI: 1% to 3%) after total hip replacement. In autopsy studies, the incidence of fatal PE ranged from 0.2% to 6.0%, increasing consistently over a period of 30 years in Japan and Hong Kong. Conclusions: Post-operative VTE is frequent in Asian general and orthopedic surgery patients and the incidence of autopsy-proven fatal PE is increasing over time. The use of routine prophylaxis in Asian patients undergoing highrisk surgical procedures should be considered.

The reported incidence of postoperative deep vein thrombosis (DVT) ranges from 3 to 47%. We were unable to locate any report in the literature regarding the incidence of DVT in the population of the Arabian peninsula. We therefore studied the incidence of DVT after major abdominal surgery as assessed by 125 I fibrinogen scanning in 103 local patients. DVT developed in 14 patients (13.6%). This is significantly lower than that reported from temperate regions. However, the morbidity rate among the DVT-positive group was high (21%). Our findings suggest that prophylactic measures against DVT should be a mandatory feature of patient care. Arabia. 1990; 10(6): 602-604 Many studies have reported widely differing incidences of postoperative deep vein thrombosis (DVT) [1][2][3][4]. It has been postulated that climatic or racial factors may be important in the genesis of this complication [7,12]. However, no such information has been available for the Gulf area of the Middle East. The present study was therefore undertaken to determine the incidence of DVT in a group of patients, most of Saudi Arabian origin and living in the Arabian Peninsula, and to allow the formulation of a rational policy of prophylaxis against DVT for this region. AB Mofti, Incidence of Deep Vein Thrombosis after Major Abdominal Surgery as Observed in Saudi Patients and MethodsIn a prospective study, all patients over 40 years of age and of Arabian origin undergoing elective major abdominal surgery at King Khalid University Hospital in Riyadh were included in the investigation. Institutional approval and prior consent to the study were obtained. No form of DVT prophylaxis was used. Relevant clinical data for each patient were recorded and included in a detailed inquiry into the known risk factors contributing to the development of DVT.A total of 103 patients were studied. There were 56 females and 47 males, with an overall age range of 40 to 80 years. Sixty-five percent of the patients were in their fifth decade. Seventy-three patients (71%) were Saudi nationals, while the remaining were of Middle Eastern extraction, living in the Gulf or Arabian peninsula.The types of operative procedures reflect the local pattern of abdominal disorders necessitating surgical intervention in our practice. Most disorders involve the hepatobiliary system or the upper alimentary tract. In only six patients (5.8%) was the large bowel the source of the primary pathology (Table 1).
