To assess the prevalence and significance of arteriovenous fistulae after prostate biopsy, we performed color Doppler ultrasonography immediately after 136 consecutive transrectal prostate needle biopsies. Pathologic results were correlated with color Doppler ultrasonographic findings. Arteriovenous fistulae developed after 17 biopsies (13%), all closed spontaneously within 18 minutes, and none were associated with unusual bleeding. Carcinoma was noted in 25 biopsy specimens (18%), 10 (40%) of which were followed by arteriovenous fistula. The correlation between malignancy and postbiopsy arteriovenous fistula was statistically significant (P < 0.0004), consistent with hypervascularity known to be present in many prostate cancers.
为评估前列腺活检后动静脉瘘的发生率及意义，我们对136例连续经直肠前列腺穿刺活检术后立即进行了彩色多普勒超声检查。将病理结果与彩色多普勒超声检查结果进行关联分析。17例活检（13%）后出现动静脉瘘，均在18分钟内自发闭合，且均未伴有异常出血。25例活检标本（18%）中发现癌，其中10例（40%）随后出现动静脉瘘。恶性肿瘤与活检后动静脉瘘之间的相关性具有统计学意义（P < 0.0004），这与许多前列腺癌中已知存在的血管增多现象一致。
