Terms starting with A

Abdominoplasty

A surgical procedure, commonly known as a tummy tuck, that removes excess skin and fat from the abdomen whilst tightening the underlying muscles. It is frequently sought after significant weight loss or pregnancy to restore a flatter abdominal contour.

Abutment

A connector component placed on top of a dental implant that serves as the attachment point for a crown, bridge, or denture. It projects above the gum line and is custom-shaped to support the final prosthetic restoration.

Accreditation

A voluntary process in which an external body evaluates a healthcare facility against published standards for patient safety, clinical governance, and quality systems. Accreditation is granted for a fixed period (typically 3-5 years) and is renewable on re-inspection. Examples include Joint Commission International (JCI), India's NABH, Malaysia's MSQH, and Korea's KOIHA.

In medical tourism: Accreditation confirms that systems are in place; it does not by itself confirm clinical competence for any individual procedure or surgeon. Patients should verify accreditation directly with the issuing body, never relying solely on the clinic's marketing claim.

ACHSI

The Australian Council on Healthcare Standards International (ACHSI) is the international arm of the Australian Council on Healthcare Standards, which accredits healthcare organisations outside Australia against internationally benchmarked quality and patient safety standards. ACHSI accreditation is recognised as a mark of excellence for hospitals in the Asia-Pacific region and beyond.

Advance Care Directive

A written document by which a person specifies their preferences for medical treatment in scenarios where they may not be able to communicate, and may name another person authorised to act on their behalf. Legal form and enforceability vary by jurisdiction.

In medical tourism: Medical tourists travelling for major surgery may wish to prepare an advance care directive in their home jurisdiction before departure and carry it with them. A lay version (a written authority for a named family member) can supplement but does not replace the formal directive.

All-inclusive Package

A medical-tourism quote presented as covering all costs of treatment and travel for a single price. In practice, all-inclusive is a marketing term, not a legal one, and the actual scope depends on the underlying contract. Line items commonly excluded include anaesthesia, implants, pre-operative tests, complications, revision, and extended hospital stay.

In medical tourism: Patients should treat 'all-inclusive' as a starting position for negotiation rather than a guarantee of scope. A defensible contract names what is included, what is excluded, and what happens in non-routine recovery scenarios.

AMH

Anti-Müllerian Hormone (AMH) is a blood marker produced by follicles in the ovaries that reflects a woman's remaining egg supply, or ovarian reserve. Fertility specialists use AMH levels to guide treatment protocols and predict response to ovarian stimulation.

Anaesthesia

The medical practice of inducing controlled, reversible loss of sensation or consciousness to enable surgery and other invasive procedures. Anaesthesia is delivered by an anaesthetist (anesthesiologist) using one or more agents — local, regional, sedation, or general — depending on the procedure and the patient.

In medical tourism: The anaesthetist's name, registration, and fee are often omitted from medical-tourism package quotes. Patients should confirm the anaesthesia plan, the anaesthetist's identity, and the written cost before paying a deposit. Anaesthesia-related complications are uncommon but can be severe.

Anaesthesia Chart

The anaesthetist's contemporaneous record of agents administered, doses, monitoring data (heart rate, blood pressure, oxygenation, end-tidal CO₂), fluids given, intra-operative adverse events, and reversal agents. Part of the patient's permanent medical record.

In medical tourism: The anaesthesia chart should be released to the patient at discharge alongside the operation report. It is essential context if the patient develops a post-operative complication and is being managed by a clinician other than the operating team.

Anaesthesiologist

A physician specialised in anaesthesia, perioperative medicine, and critical care. In medical-tourism contexts, the anaesthesiologist's training, board certification, and presence throughout the procedure are independent quality markers separate from the surgeon's credentials. In many jurisdictions a certified registered nurse anaesthetist (CRNA) or anaesthetic technician provides intra-operative monitoring under the anaesthesiologist's supervision.

Angioplasty

A minimally invasive cardiovascular procedure in which a balloon-tipped catheter is inserted into a narrowed or blocked artery and inflated to widen the vessel and restore blood flow. It is often performed in conjunction with the placement of a coronary stent.

Anti-Embolism Stockings

Graduated compression hosiery prescribed to patients at risk of deep vein thrombosis, particularly during and after surgery or prolonged periods of immobility such as long-haul flights. They apply external pressure to the lower limbs to promote venous return and reduce the risk of clot formation.

Antibiotic Prophylaxis

The preventive administration of antibiotics before, during, or shortly after a surgical or invasive procedure to reduce the risk of post-operative infection. The choice of antibiotic and duration of course depends on the procedure type and the patient's individual risk factors.

Antral Follicle Count

A transvaginal ultrasound assessment that counts the small, resting follicles visible in both ovaries at the beginning of a menstrual cycle. Together with AMH, it is used to estimate ovarian reserve and predict how a patient will respond to fertility drug stimulation.

Arbitration (Medical)

An alternative dispute resolution process in which a neutral third-party arbitrator hears evidence and makes a binding or non-binding decision regarding a medical dispute, such as a negligence claim. It is often faster and less costly than court litigation and may be mandated by a hospital's patient agreement.

Arthroplasty

A surgical procedure to restore the function of a joint, most commonly the hip or knee, by resurfacing or replacing the damaged joint with a prosthetic implant. It is indicated for patients with severe arthritis or joint damage that has not responded to conservative treatments.

Arthroscopy

A minimally invasive surgical technique in which a small camera (arthroscope) is inserted into a joint through a tiny incision, allowing the surgeon to diagnose and treat conditions such as torn cartilage or ligament damage. Recovery is generally faster than with open joint surgery.

ASA Classification

The American Society of Anesthesiologists Physical Status Classification, a six-level scale (ASA I-VI) that grades a patient's pre-operative health for anaesthetic risk. ASA I is a normal healthy patient; ASA III has severe systemic disease; ASA V is a moribund patient not expected to survive without surgery. ASA score is one of the inputs that determine peri-operative monitoring intensity, ICU planning, and informed-consent discussions.

Astigmatism

A refractive error caused by an irregular curvature of the cornea or lens, resulting in blurred or distorted vision at all distances. It can be corrected with spectacles, contact lenses, or refractive laser surgery such as LASIK or SMILE.

Autologous Fat Transfer

A surgical technique in which fat is harvested from one area of the patient's own body through liposuction, processed, and re-injected into another area to add volume, correct contour defects, or rejuvenate the face, hands, or breasts. As the material is derived from the patient's own tissue, the risk of rejection is eliminated, though a proportion of the transferred fat may be reabsorbed over time.
