Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

One of the neural tube defects, myelomeningocele, is a congenital anomaly developing in the fourth gestational week. It is characterized by insertion of neural elements into a pouch floored by meninx through a vertebral defect.

The aetiology is multifactorial. causes are genetic properties, geographic factors, and deficiency of folic acid.

Meningomyelocele incidence range between 1 and 2/1000 live births. The defect location can reside anywhere between the cervical region and the sacrum.

surgical closure of the defect is performed to prevent cerebrospinal fluid leakage and central nervous system infections. it is a combined work between neurosurgery and plastic surgery. Fascial turnover flaps, muscle flaps, local fasciocutaneous flaps.

With the emerging concepts of perforator flaps in the last three decades, the reconstruction of myelomeningocele defects has completely changed since the anatomy of the dorsal intercostal artery perforators (DIAP) and lumbar artery perforators(LAP) has been fully studied.

Despite utilizing perforator flaps having greatly improved the outcome of myelomeningocele reconstruction, venous compromise remained a major concern associated with complications.

By preserving, the perforator vessels and minimizing the amount of tissue that is removed, the Perforator Plus technique can improve blood flow and decrease the risk of venous congestion.

Preoperative perforator mapping may be executed by a multitude of diagnostic modalities. Hand-held Doppler (HHD), color-coded duplex sonography (CCDS), computed tomography angiography (CTA), magnetic resonance angiography (MRA) and others may be applied.

Systematic reviews of the literature revealed that CCDS has the highest sensitivity and positive predictive value to identify perforators for flaps.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
