Embolism
|
D004617 |
[Blocking of a blood vessel by an embolus which can be a blood clot or other undissolved material in the blood stream.

|
Embolism and Thrombosis
|
D016769 |
[A collective term for pathological conditions which are caused by the formation of a blood clot (THROMBUS) in a blood vessel, or by blocking of a blood vessel with an EMBOLUS, undissolved materials in the blood stream.

|
Embolism, Air
|
D004618 |
[Blocking of a blood vessel by air bubbles that enter the circulatory system, usually after TRAUMA; surgical procedures, or changes in atmospheric pressure.
] |
|
Embolism, Amniotic Fluid
|
D004619 |
[Blocking of maternal circulation by AMNIOTIC FLUID that is forced into uterine VEINS by strong UTERINE CONTRACTION near the end of pregnancy. It is characterized by the sudden onset of severe respiratory distress and HYPOTENSION that can lead to maternal DEATH.
] |
|
Embolism, Cholesterol
|
D017700 |
[Blocking of a blood vessel by CHOLESTEROL-rich atheromatous deposits, generally occurring in the flow from a large artery to small arterial branches. It is also called arterial-arterial embolization or atheroembolism which may be spontaneous or iatrogenic. Patients with spontaneous atheroembolism often have painful, cyanotic digits of acute onset.

|
Embolism, Fat
|
D004620 |
[Blocking of a blood vessel by fat deposits in the circulation. It is often seen after fractures of large bones or after administration of CORTICOSTEROIDS.
] |
|
Embolism, Paradoxical
|
D019320 |
[Blockage of an artery due to passage of a clot (THROMBUS) from a systemic vein to a systemic artery without its passing through the lung which acts as a filter to remove blood clots from entering the arterial circulation. Paradoxical embolism occurs when there is a defect that allows a clot to cross directly from the right to the left side of the heart as in the cases of ATRIAL SEPTAL DEFECTS or open FORAMEN OVALE. Once in the arterial circulation, a clot can travel to the brain, block an artery, and cause a STROKE.

|
Embolization, Therapeutic
|
D004621 |
[A method of hemostasis utilizing various agents such as Gelfoam, silastic, metal, glass, or plastic pellets, autologous clot, fat, and muscle as emboli. It has been used in the treatment of spinal cord and INTRACRANIAL ARTERIOVENOUS MALFORMATIONS, renal arteriovenous fistulas, gastrointestinal bleeding, epistaxis, hypersplenism, certain highly vascular tumors, traumatic rupture of blood vessels, and control of operative hemorrhage.

Embryo Culture Techniques
|
D046149 |
[The technique of maintaining or growing mammalian EMBRYOS in vitro. This method offers an opportunity to observe EMBRYONIC DEVELOPMENT; METABOLISM; and susceptibility to TERATOGENS.

|
Embryo Disposition
|
D019924 |
[Utilization or disposal of an embryo that is fertilized but not immediately transplanted and resulting course of action.
] |
|
Embryo Implantation
|
D010064 |
[Endometrial implantation of EMBRYO, MAMMALIAN at the BLASTOCYST stage.
] |
|
Embryo Implantation, Delayed
|
D010065 |
[Delay in the attachment and implantation of BLASTOCYST to the uterine ENDOMETRIUM. The blastocyst remains unattached beyond the normal duration thus delaying embryonic development.
] |
|
Embryo Loss
|
D020964 |
[Early pregnancy loss during the EMBRYO, MAMMALIAN stage of development. In the human, this period comprises the second through eighth week after fertilization.
] |
|
Embryo Research
|
D033041 |
[Experimentation on, or using the organs or tissues from, a human or other mammalian conceptus during the prenatal stage of development that is characterized by rapid morphological changes and the differentiation of basic structures. In humans, this includes the period from the time of fertilization to the end of the eighth week after fertilization.
] |
|
Embryo Transfer
|
D004624 |
[The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.
, The delayed transfer of embryos at the blastocyst stage provides a means to eliminate unhealthy embryos that do not develop normally. The selection and transfer of superior blastocysts reduces the need for multiple-embryo transfer and the risks of high-order multiple gestation.
, Embryos are transferred to the fallopian tubes.

|
Embryo, Mammalian
|
D004622 |
[The anatomical parts that make up a mammalian organism in the early stages of development.
, The entity of a developing mammal (MAMMALS), generally from the cleavage of a ZYGOTE to the end of embryonic differentiation of basic structures. For the human embryo, this represents the first two months of intrauterine development preceding the stages of the FETUS.
] |
|
Embryo, Nonmammalian
|
D004625 |
[The anatomical parts of a non-mammalian animal during its early stages of development.
, The developmental entity of a fertilized egg (ZYGOTE) in animal species other than MAMMALS. For chickens, use CHICK EMBRYO.
] |
|
Embryoid Bodies
|
D058732 |
[Spontaneous aggregations of human embryonic stem cells that occur in vitro after culturing in a medium that lacks LEUKEMIC INHIBITORY FACTOR. The embryoid bodies can further differentiate into cells that represent different lineages.
] |
|
Embryology
|
D004626 |
[The study of the development of an organism during the embryonic and fetal stages of life.
] |
|
Embryonal Carcinoma Stem Cells
|
D054278 |
[The malignant stem cells of TERATOCARCINOMAS, which resemble pluripotent stem cells of the BLASTOCYST INNER CELL MASS. The EC cells can be grown in vitro, and experimentally induced to differentiate. They are used as a model system for studying early embryonic cell differentiation.
