1/5. Three-dimensional power Doppler in the diagnosis of ovarian torsion.Recent advances in ultrasound technology have enabled the diagnosis of overall tissue vascularization by three-dimensional (3D) power Doppler. This case report describes 3D power Doppler characteristics of unilateral ovarian torsion 2 weeks after embryo transfer in a pregnant patient with bilateral hyperstimulated ovaries. Before laparoscopic treatment the twisted right ovary showed the following 3D power Doppler indices: mean grayness index, 15.66; vacularization index, 0.24; flow index, 21.99; vascularization flow index, 0.05. One hour after laparoscopic treatment 3D power Doppler indices of the untwisted ovary were as follows: mean grayness index, 25.61; vacularization index, 3.81; flow index, 42.800; vascularization flow index, 1.63. The resistance index of the ovarian vessels before and after laparoscopy showed no significant difference (5.1 vs. 5.2). The diagnosis of ovarian torsion can be better made with 3D power Doppler sonography than with two-dimensional Doppler sonography.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/5. Massive ovarian edema revealing gastric carcinoma: a case report.Tumor-like enlargement of the ovaries due to accumulation of edema fluid within the ovarian stroma is referred to as massive ovarian edema (MOE). The pathogenesis of MOE is thought to be intermittent torsion of the ovary on its pedicle, causing partial obstruction of venous and lymphatic drainage. The diagnosis of MOE is based on imaging techniques. The case described here due to ovarian lymphatic vessel obstruction by carcinoma cells shows that metastatic disease may be a cause of MOE.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/5. Postpartum spontaneous rupture of ovarian artery aneurysm.A case of spontaneous rupture of a right ovarian artery aneurysm after delivery is presented. Search of the literature revealed 3 similar cases of spontaneous rupture during early peurperium and 1 case of spontaneous rupture of an ovarian artery on the third postpartum day with no abnormal findings of the vessel at the site of rupture.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/5. Intravascular gas within an ovarian tumor: a CT sign of ovarian torsion.A case of twisted ovarian tumor with intravascular gas is presented, and the mechanism of the gas formation is discussed. On the basis of the probable mechanism of gas formation observed in dead fetuses, the gas seen in the present case is considered to have been oxygen released from trapped oxyhemoglobin within the tumor vessels. "Intravascular gas" within an ovarian tumor, although extremely rare, is diagnostic of ovarian torsion.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
5/5. Successful management of chylous ascites after laparoscopic presacral neurectomy.Laparoscopic presacral neurectomy is a safe, effective, and well-established surgical procedure to relieve intractable dysmenorrhea and chronic pelvic pain. In one woman, substantial lymphatic leakage occurred due to damaged lymphatic vessels. Adequate exposure and coagulation of the presacral lymphatic zone through the laparoscope resolved the problem, and a substantial amount of chylous ascites was removed. The patient fully recovered after the intervention.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
