abstract 14779 soleal Vein Dilatation assessed by ultrasonography is an independent predictor for deep Vein thrombosis after total hip arthroplasty
Circulation, 2015Co-Authors: Satoshi Yuda, Kenji Yasui, Ayumi Okubo, Atsuko Muranaka, Akiyoshi Hashimoto, Atsushi Teramoto, Satoshi Nagoya, Kazufumi Tsuchihashi, Toshihiko Yamashita, Tetsuji MiuraAbstract:Introduction: Deep Vein thrombosis (DVT) develops after lower limb arthroplasty despite the current use of prohylaxis. Thus, accurate risk stratification is warranted to establish new prophylactic strategies. Soleal Vein (SV) Dilatation is often found by ultrasonography, which is performd for the screeing of the DVT. However, if the SV Dilatation is usable for prediction of the DVT after the lower limb arthroplasty remains unclear. Hypothesis: We aimed to examine whether the SV Dilatation assessed by ultrasonography predicts the DVT after the lower limb arthroplasty. Methods: Ultrasonography was performed pre- (mean 5 days) and postoperatively (mean 8 days) in 135 osteoarthritic patients (age 66+/-13 years, 76% women) who underwent total hip arthroplasty (THA; n = 99) or knee arthroplasty (TKA; n = 36). The patients with preoperative DVT were excluded. Presence of DVT was diagnosed by ultrasonography, which was performed from the bilateral femoral to lower limb. Increased diameter of SV (>10 mm) assessed by ultrasonography was defined as the SV Dilatation. Results: Thirty seven patients (27%) developed the DVT, which was proximal in one (3%) and distal in 36 (97%), after the lower limb arthroplasty. SV dilation was observed in 14 patients (10%). Of these, 11 (79%) had the postoperative DVT. Multivariate logistic regression analysis indicated that age (odds ratio [OR] 1.1, 95% CI 1.01 to 1.11, p=0.016), female (OR 4.9, 95% CI 1.18 to 19.9, p=0.028), TKA (OR 2.7, 95% CI 1.01 to 7.37, p=0.047), and SV Dilatation (OR 18.8, 95% CI 4.0 to 88.8, p Conclusions: In addtion to well-known risk factors for postoperative DVT, the SV Dilatation assessed by ultrasonography is an independent predictor of the DVT after the THA. Assessment of the SV diameter by ultrasonography is useful for identfying patients with high risk for the postoprtative DVT after the THA.

soleal Vein Dilatation assessed by ultrasonography is an independent predictor for deep Vein thrombosis after major orthopedic surgery
Journal of Cardiology, 2017Co-Authors: Satoshi Yuda, Kenji Yasui, Ayumi Okubo, Chihiro Kobayashi, Atsuko Muranaka, Hirofumi Ohnishi, Akiyoshi Hashimoto, Atsushi Teramoto, Satoshi Nagoya, Kazufumi TsuchihashiAbstract:Abstract Background Deep Vein thrombosis (DVT) develops after major orthopedic surgery despite the current use of prophylaxis. DVT frequently develops in the soleal Vein (SV) and might develop easily at the site of SV Dilatation because of blood flow stasis. However, whether preoperative SV Dilatation detected by ultrasonography predicts DVT after major orthopedic surgery remains unknown. Objective We examined whether SV Dilatation detected by preoperative ultrasonography predicts DVT after major orthopedic surgery. Methods Ultrasonography was performed preoperatively and postoperatively in 243 patients with orthopedic diseases (mean age of 67 ± 13 years, 77% women) who underwent total hip arthroplasty (THA, n = 180) or total knee arthroplasty (TKA, n = 63). Presence of DVT was diagnosed by ultrasonography and SV diameter ≥10 mm was defined as SV Dilatation. Patients with preoperative DVT were excluded. Results Sixty-nine patients (28%) developed postoperative DVT. SV Dilatation was found in 24 patients (10%), and 16 (67%) of those patients had postoperative DVT. Multivariate logistic regression analysis showed that female gender [odds ratio (OR): 4.09, p = 0.004], TKA (OR: 2.52, p = 0.011), and SV Dilatation (OR: 6.67, p d -dimer value, independently predict postoperative DVT. Subgroup analyses according to the operation site showed that female gender (OR: 3.27, p = 0.043) and SV Dilatation (OR: 3.72, p = 0.022) were independent predictors of postoperative DVT in the THA group. SV Dilatation (OR: 12.0, p = 0.027) was an independent predictor of postoperative DVT also in the TKA group. Conclusions In addition to gender and TKA, SV Dilatation detected by ultrasonography is an independent predictor of DVT after major orthopedic surgery. Determination of SV diameter by ultrasonography before major orthopedic surgery is useful for assessing the risk of postoperative DVT.

Doppler demonstration of cystic Vein Dilatation secondary to portal Vein thrombosis
Surgical Endoscopy, 1991Co-Authors: G. G. Cerri, A. Habr-gama, D. Paranaguá-vezozzo, M. C. C. Machado, H. W. Pinotti, A. MagalhãesAbstract:High-resolution duplex ultrasound was used to demonstrate vascular Dilatation in the gallbladder wall in eight patients with portal Vein thrombosis. Gallbladder thickening, combined with a higher incidence of gallstone disease in patients with chronic hepatic disease can be misinterpreted as acute cholecystitis. The Doppler is helpful in detecting the vascular cause of the gallbladder wall thickening thus helping to reduce the frequency of inappropriate cholecystectomy.
