1/52. Numerous and large Bier's spot associated with pregnancy.We report a patient with anemic macules over cyanotic skin which started in the 8th month of a normal pregnancy. We thought that these lesions were close to Bier's spot description although it has never been described during pregnancy. The relationship with pregnancy is likely because skin lesions regress in post-partum. It probably represents an exaggerated physiological response of small vessels to venous hypertension observed during pregnancy in predisposed women.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/52. Disseminated intravascular meconium in a newborn with meconium peritonitis.A 3-day-old premature infant with meconium peritonitis, periventricular leukomalacia, and pulmonary hypertension died with respiratory insufficiency. An autopsy disclosed intravascular squamous cells in the lungs, brain, liver, pancreas, and kidneys. Numerous pulmonary capillaries and arterioles were occluded by squamous cells, accounting for pulmonary hypertension. brain parenchyma surrounding occluded cerebral vessels showed infarct and gliosis. A mediastinal lymph node filled with squamous cells alluded to the mechanism by which these cells from the peritoneal cavity likely entered the bloodstream--namely, via diaphragmatic pores connecting with lymphatics. Thus, disseminated intravascular meconium rarely may complicate meconium peritonitis and have devastating consequences.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/52. Congenital hyperthyroidism: autopsy report.We report the autopsy of a stillborn fetus with congenital hyperthyroidism born to a mother with untreated Graves' disease, whose cause of death was congestive heart failure. The major findings concerned the skull, thyroid, heart, and placenta. The cranial sutures were closed, with overlapping skull bones. The thyroid was increased in volume and had intense blood congestion. Histological examination showed hyperactive follicles. The heart was enlarged and softened, with dilated cavities and hemorrhagic suffusions in the epicardium. The placenta had infarctions that involved at least 20% of its surface, and the vessels of the umbilical cord were fully exposed due to a decrease in Wharton's jelly. hyperthyroidism was confirmed by the maternal clinical data, the fetal findings of exophthalmia, craniosynostosis, and goiter with signs of follicular hyperactivity. Craniosynostosis is caused by the anabolic action of thyroid hormones in bone formation during the initial stages of development. The delayed initiation of treatment in the present case contributed to the severity of fetal hyperthyroidism and consequent fetal death.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/52. Vascular anastomoses between the iris and persistent hyperplastic primary vitreous.Prominent radial iris blood vessels created small but definite pupillary notches in five children with persistent hyperplastic primary vitreous and persistence of the tunica vasculosa lentis. Detection of these abnormal iris vessels suggested the presence of persistent hyperplastic primary vitreous and related syndromes even when the diagnosis was obscured by the presence of an opaque lens. These vessels represented early developmental arrest and may have been associated with abnormal development of the macula and optic nerve. Surgical and amblyopia therapy, therefore, may not provide useful vision, and should be undertaken with caution.- - - - - - - - - - ranking = 7.3888959455072keywords = blood vessel, vessel (Clic here for more details about this article) |
5/52. Fetal chylothorax response to maternal dietary treatment.BACKGROUND: Fetal chylothorax is associated with elevated perinatal mortality. Development of mediastinal shift with significant lung compression before 35 weeks' gestation needs treatment. CASE: A 24-year-old gravida 2, para 0 presented at 26 weeks' gestation with a fetal pleural effusion with a mediastinal shift and abnormal Doppler velocimetry indices in several vessels. Thoracentesis was successful but 3 days later, the fetal effusion had reaccumulated. Because of fetal position, a pleuro-amniotic shunt was difficult technically, so maternal medical treatment was initiated with a low-fat, high medium-chain triglyceride diet. After initial mild decrease, the estimated volume of the fetal chylothorax remained stable until 36 weeks' gestation, at which time we delivered by cesarean an infant with good Apgar scores. After aspiration of the remaining thoracic fluid and administration of a similar diet, the infant did well, with normal growth and development. CONCLUSION: Maternal dietary treatment might help delay the need for thoracentesis in cases of fetal chylothorax.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/52. Torsion of the pregnant uterus.A 31-year-old woman, with a history of previous cesarean section and right oophorectomy, was admitted for a repeat cesarean section. After the commencement of surgery uterine torsion was diagnosed because of the anterior position of the remaining left ovary and tube, the absence of normal uterovesical peritoneum, and extremely engorged vessels in the lower uterine surface. Posterior classical hysterotomy was performed and a healthy female baby was delivered. Following delivery of the baby and suturing the incision site of the uterus, the contracted uterus was detorted and put back in the pelvic cavity. Extreme uterine torsion of 180 degrees at term is a rare obstetric event. This paper presents a case of uterine torsion at full term pregnancy in which the delivery and repositioning of the uterus was successful.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/52. serum tryptase analysis in a woman with amniotic fluid embolism. A case report.BACKGROUND: Recent studies have noted a striking similarity between amniotic fluid embolism (AFE) and anaphylaxis. serum tryptase levels may therefore serve as a marker of mast cell degranulation in AFE cases. CASE: A 40-year-old woman, gravida 6, para 4, experienced the acute onset of facial erythema, eclampsia-type seizures, severe hypoxia, cardiac arrest and disseminated intravascular coagulation while in early active labor. The patient was declared dead 37 minutes after the onset of resuscitative efforts. At autopsy, fetal squames were found within the pulmonary tree, uterine blood vessels and brain. A peripheral venous blood specimen, obtained approximately one and a half hours postmortem, revealed a tryptase level of 4.7 ng/mL (normal, < 1). CONCLUSION: An elevated serum tryptase level, in conjunction with our patient's clinical history, adds further supporting evidence to the concept of AFE as an anaphylactoid syndrome of pregnancy.- - - - - - - - - - ranking = 5.3888959455072keywords = blood vessel, vessel (Clic here for more details about this article) |
8/52. Development of histologic features of scleroderma in congenital lesions.BACKGROUND: Localized scleroderma has been reported after radiation therapy, but has never been reported to occur at the site of a congenital lesion. CASE REPORT: We present two patients, both with family histories of autoimmune disease, who reported unilateral hypopigmented areas on the trunk since birth. The areas remained asymptomatic and grew with the patients until adulthood when the areas became indurated then firm and showed hyperpigmentation. histology: Histologically, both lesions showed features of localized scleroderma with diffuse sclerosis of collagen and loss of periadnexal fat. There was a perivascular lymphoplasmocytic infiltrate with occasional eosinophils extending into the subcutaneous fat predominantly along fat septae, and diffuse loss of CD34 stromal cell populations within the lesions. CONCLUSION: We propose that somatic mutations affecting vessels may predispose to increased endothelial cell apoptosis. This could lead to the development of an autoimmune response in some individuals, and the areas of localized scleroderma may be markers of susceptibility to autoimmune disease.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
9/52. 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) |
10/52. Antiphospholipid antibody syndrome complicated by Grave's disease.The report describes a woman with primary antiphospholipid antibody syndrome complicated with Grave's disease. Developing symptoms included a small cutaneous nodule on her finger and subsequently ecchymotic purpura on the cheeks, ears, buttocks and lower legs. Histological examinations showed thrombosed vessels in the dermis without or with hemorrhage, respectively. Laboratory investigation revealed positive lupus anticoagulant and immunogenic hyperthyroidism due to Grave's disease. There is a close relationship between the cutaneous manifestation of antiphospholipid antibody syndrome and the activities of Grave's disease and a possible link of antiphospholipid antibody syndrome with Grave's disease was suggested both by the etiology of the disease as well as the disease activity.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
