There is some evidence that postoperative deep vein thrombosis (DVT) may be commoner in cool than in warm climates. To determine whether this complication is less common in the subtropical climate of Brisbane than in more temperate locations, the incidence of DVT after major abdominal surgery was assessed by 125I fibrinogen scanning. In order to avoid overestimating the incidence of DVT, abnormal scans were accepted as diagnostic only if the DVT was confirmed by venography or if the abnormality on the scan fulfilled more stringent criteria than have previously been applied. Thirty-six of 152 patients (24 per cent) developed a DVT; this incidence was significantly lower than in one previous study from Melbourne and higher than that found in South-East Asia and East Africa, but was not significantly different from that reported from Sydney, Japan and several centres in North America and Britain. There was no apparent seasonal variation in the incidence of the complication. The geographical variation in incidence of postoperative DVT may have been overestimated in previous reports and may be at least partly due to variations in screening technique.
有证据表明，术后深静脉血栓形成（DVT）在气候凉爽地区可能比温暖地区更为常见。为了确定在布里斯班亚热带气候下该并发症是否比在温带地区更少见，通过125I纤维蛋白原扫描评估了腹部大手术后DVT的发生率。为避免高估DVT的发生率，仅在静脉造影证实存在DVT或扫描异常符合比以往更严格的标准时，才将异常扫描结果视为诊断依据。152例患者中有36例（24%）发生了DVT；这一发生率显著低于此前墨尔本的一项研究，高于东南亚和东非地区的发生率，但与悉尼、日本以及北美和英国的几个中心报告的发生率无显著差异。该并发症的发生率没有明显的季节性变化。以往报告中可能高估了术后DVT发生率的地理差异，这可能至少部分归因于筛查技术的差异。
