  • Peritoneovenous shunt scintigraphy as an aid in the evaluation of its patency in adults.

Important risk information


PULMOTECH MAA is contraindicated in patients with:

  • Severe pulmonary hypertension.
  • A history of hypersensitivity to albumin human. Reactions have included anaphylaxis.

Warnings and precautions

Pulmonary Hypertension: Administer the lowest number of particles possible, have emergency resuscitation equipment available, and monitor patients for adverse reactions.
Hypersensitivity Reactions: Have emergency resuscitation equipment and trained personnel available prior to administration of Technetium Tc 99m Albumin Aggregated Injection. Interrupt the administration if a reaction occurs during administration. Monitor patients.
Risk of Temporary Impediment to Blood Flow in Patients with Right-to-Left Heart Shunts: Administer the lowest possible number of particles of Technetium Tc 99m Albumin Aggregated Injection.
Radiation Risks: Long-term cumulative radiation exposure is associated with an increased risk for cancer. Ensure safe handling to minimize radiation exposure to the patient and health care providers. Advise patients to hydrate before and after administration and to void frequently after administration.

Adverse reactions

The following adverse reactions have been reported: Death in patients with severe pulmonary hypertension, anaphylaxis, impairment of cardiac and circulatory functions in the form of changes in respiration, pulse, blood pressure, chest pain, possible syncope, urticaria, reddening of the face, sweating, nausea, and injection site reaction.

Use in specific populations

Lactation: Temporarily discontinue breastfeeding and pump and discard breast milk for a minimum of at least 24 hours after administration of Technetium Tc 99m Albumin Aggregated Injection.

Pregnancy: Available data from case reports on Technetium Tc 99m Albumin Aggregated Injection use are insufficient to evaluate drug-associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Although all radiopharmaceuticals have the potential to cause fetal harm depending on the fetal stage of development and the magnitude of the radiation dose, the radiation exposure to the fetus from technetium Tc 99m albumin aggregated is expected to be low (less than 0.50 mGy).

Frequently asked questions
