MRI diagnosis of the complications of polyamide hydrogel injection for augmentation mammoplasty / 中华放射学杂志

Objective To analyze MRI findings and its clinical significance in complications of polyamide hydrogel injection for augmentation mammoplasty. Methods The complication findings of MR imaging in 20 cases with polyamide hydrogel injection for augmentation mammoplasty were retrospectively reviewed and analyzed. Results In 20 patients, 26 breasts suffered from complications, including infection (n=5) with pieces of long T_1and long T_2 signals, aseptic inflammation (n=2) with pieces of slight long T_1and moderate T_2 signals, hard nodule (n=10) with long T_1 and long T_2 signals, and rupture (n=5) with pieces and nodes of long T_1 and long T_2 signals on MR images. Conclusion MRI has the great diagnostic value in the detection of complications after polyamide hydrogel injection for augmentation mammoplasty, and it should be taken as the first diagnostic choice.

Imaging diagnosis of the acute Achilles tendon rupture / 中华放射学杂志

Objective To evaluate the diagnostic value of Achilles tendon rupture by using X-ray plain films and MR images. Methods The plain films and MRI findings in 21 patients with operation proved acute Achilles tendon rupture were analyzed, and every manifestation on MR and operation were compared.Results The Achilles tendon rupture was diagnosed on MRI in all 21 cases. Complete rupture of Achilles tendon was showed in 7 and partial rupture in 14. MRI appearance of the rupture represented as thickening of Achilles tendon, hyperintensity in the tendon, and completely or partly discontinuance of the fibrous bundle. X-ray showed Achilles tendon rupture in 5, suspicious rupture in 12, and normal in 4. Operation showed Achilles tendon complete rupture in 9 and partial rupture in 12.Conclusion MRI can accurately show the degree and location of acute Achilles tendon rupture, which is very helpful for treatment. X-ray is the adminicular method in detecting Achilles tendon rupture and the diagnosis should be depended on MRI to confirm the the acute Achilles tendon rupture.

Pelvis Massive Hemorrhage Treated by Transcatheter Internal Iliac Artery Embolization / 实用放射学杂志

Objective To explore the embolization technique,embolus choice and preventing complications of transcatheter internal iliac artery embolization in treating pelvis massive hemorrhage.Methods Bilateral selective internal iliac artery embolization utilizing gelfoam was done in 11 patients of pelvis massive hemorrhage (including 3 cases of bladder carcinoma,5 cases of cervix carcinoma,one case of choriocarcinoma and 2 cases of puerperal hemorrhage.Results Prompt hemostasis was obtained immediately after first embolization in all 11 patients,one of them showed recurrent bleeding after 24 hours and underwent treatment again.Patients were followed up for 10~90 days,no hemorrhage or any kind of complication noted in all patients.Conclusion Transcatheter internal iliac artery embolization is a simple,less invasive,safe and effective therapy for pelvis massive hemorrhage,should be taken as the first choice.

Clinical Application of Transcatheter Uterine Artery Embolization for Treatment of Hysteromyoma / 实用放射学杂志

Objective To study the methods,therapeutic effect and complications of transcatheter uterine artery embolization(TUAE)for hysteromyoma.Methods There were 82 patients with hysteromyoma confirmed by clinical,color Doppler ultrasound and CT in this study.Among them,5 hysteromyoma located under mucous membrane,72 in the myometrium,5 under serous membrane.15 cases were single hysteromyoma,67 were multiple hysteromyoma.Bilateral uterine arteries were embolized with lipiodol-pingyangmycin emulsion(LPE)and Gelfoam particles using Seldinger technique.All patients were followed up for 3 to 6 months.Results The successful rate of catheterization almost reached 100%.B-mode ultrasound examination 3 months after the procedure showed averagely 51% of decrease in volume of the masses and decrease of blood flow of tumors in all cases,the volume of tumors decreased 43% and 19 hysteromyoma disappeared for 6 months later.Menses returned to regular cycle.In the patients with anemia,the hemoglobin concentration recovered to normal level.The rate of complication was 6%(5/82),and recovered to normal after special treatment.Conclusion TUAE is an effective and less invasive way to treat hysteromyoma,the complications of TUAE are preventable and curable.

DSA diagnosis and interventional therapy for non-neoplastic lower digestive tract hemorrhage / 介入放射学杂志

Objective To study the clinical value of DSA diagnosis and interventional therapy for non-neoplastic lower digestive tract hemorrhage. Methods Non-neoplastic lower digestive tract hemorrhage were diagnosed in 21 patients. Eight cases underwent embolization with gelfoam and 13 cases with infusion of pitressin. Results Intestinal angiodysplasia was found in 14 cases, colonic diverticulum in 2 and hemorrhage of unknown cause in 5. Hemorrhage in all patients was stopped after the interventional therapy with no serious complications. During the follow-up of 25～74 months, intestinal angiodysplasia bleeding recurred in 4 patients. Conclusions DSA is very helpful in the diagnosis of non-neoplastic lower digestive tract hemorrhage and interventional therapy is safe and effective for the stoppage of the bleeding.
