Patterns and distribution of isolated calf deep vein thrombosis

摘要: Abstract Purpose: In the search for calf deep vein thrombosis (DVT) with color-flow duplex scanning (CFDS), most vascular laboratories investigate only posterior tibial and peroneal veins. Few assess soleal gastrocnemial This study was designed to determine patterns distribution of isolated DVT, including Methods: last 3 years, 5250 patients (mean age, 66 ± 15 years; range, 22 93 years) were referred laboratory clinical suspicion DVT underwent examination CFDS. All superficial named veins, excluding anterior from groin ankle, imaged. Of veins in calf, peroneal, tibial, gastrocnemial, examined throughout their length. Results: detected 14% patients. Isolated 282 limbs 251 (4.8%). No significant difference noted sex (114 men vs 137 women; P = .15) or limb preference (145 left right; .5). The frequently involved, 115 (41%) affected. involved 109 (39%), followed by 105 (37%) 79 (29%). Thrombus alone found 57 (20%), 48 (17%), 41 (15%), 35 (12%). confined a single paired 181 (64%). involving two different (27%) second frequent pattern, thrombus three (7%) four (1.4%) less prevalent. not routinely investigated 113 (40%; soleal, n=57; n=48; + n=8). Multifocal origin thrombosis, defined as thrombi that do anatomically communicate, identified 63 (22%). Conclusion: Forty percent acute would be judged have normal CFDS results if muscular 22% limbs. prevalence any either combination is comparable. Accordingly, should routinely.
