Contraception
|July 26, 2016
Summary
Intravascular migration of contraceptive implants to the pulmonary artery is a rare risk. Barium sulfate in implants aids diagnosis, and placement on the biceps may prevent this serious adverse event.
Area of Science:
- Reproductive Health
- Medical Device Safety
- Radiology
Background:
- Contraceptive implants are widely used for long-term reversible contraception.
- Rare cases of intravascular migration of these devices have been reported.
- Spontaneous reporting systems are crucial for identifying adverse events.
Observation:
- Two new cases of contraceptive implant migration into the venous system were identified.
- These implants embolized to the pulmonary artery.
- Previous case reports also documented similar migration events.
Findings:
- The inclusion of barium sulfate in contraceptive implants facilitates diagnosis of intravascular migration via chest X-ray.
- Pulmonary artery embolism from contraceptive implants is a rare but serious complication.
- Delayed diagnosis can lead to endothelialization, complicating implant removal.
Implications:
- Prompt diagnosis and intervention are critical for managing implant embolism.
- Surgical removal from pulmonary artery branches is technically challenging and carries risks.
- Altering implant placement to the anterior biceps surface may reduce the risk of intravascular migration.

01:21Intrauterine Drug Delivery Systems
101
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...

01:09Cell Migration
19.1K
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

01:19Cell Migration
7.2K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

3.4K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...
