Official Description

Transcatheter therapy, infusion other than for thrombolysis, any type (eg, spasmolytic, vasoconstrictive)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Transcatheter therapy, as described by CPT® Code 37202, involves the infusion of medication into a blood vessel that is not a coronary vessel. This procedure is specifically for the administration of agents other than thrombolytics, which are typically used to dissolve blood clots. The types of medications that may be infused include spasmolytic agents, which help relieve spasms in blood vessels, and vasoconstrictive agents, which can narrow blood vessels to control bleeding or manage other vascular conditions. The procedure is performed using the Seldinger technique, a well-established method that involves puncturing the skin and the blood vessel with a needle to gain access. Following this, a guidewire is inserted through the needle and advanced to the targeted vascular area where the medication will be delivered. The infusion of the agent is then carried out, and once the medication has been administered, the catheter is removed, and the blood vessel is repaired. This procedure is crucial for treating various vascular conditions and requires careful execution to ensure patient safety and effective treatment outcomes.

1. Indications

Transcatheter therapy with infusion other than for thrombolysis is indicated for various vascular conditions where the administration of specific medications is necessary to manage symptoms or treat underlying issues. The following are the explicitly provided indications for this procedure:

  • Spasmolytic therapy - This procedure may be performed to alleviate vascular spasms that can restrict blood flow and cause pain or other complications.
  • Vasoconstrictive therapy - Infusion of vasoconstrictive agents may be indicated to control bleeding or manage conditions that require narrowing of blood vessels.
  • Other vascular conditions - The procedure can be utilized for various other indications that necessitate the infusion of medications directly into the vascular system, excluding thrombolytic agents.

2. Procedure

The procedure for transcatheter therapy with infusion other than for thrombolysis involves several critical steps, each essential for the successful administration of the medication. The following procedural steps are outlined:

  • Step 1: Accessing the Blood Vessel - The procedure begins with the application of local anesthesia to the puncture site. Using the Seldinger technique, a needle is carefully inserted through the skin and into the targeted blood vessel. This technique allows for safe access to the vascular system while minimizing trauma to surrounding tissues.
  • Step 2: Insertion of the Guidewire - Once the needle is in place, a guidewire is threaded through the needle and advanced into the vascular bed where the medication will be infused. This guidewire serves as a pathway for the subsequent catheter insertion.
  • Step 3: Catheter Placement - A catheter is then advanced over the guidewire to the specific location within the vascular system where the therapeutic agent is to be delivered. This step is crucial for ensuring that the medication is infused precisely where it is needed.
  • Step 4: Infusion of the Agent - The selected spasmolytic, vasoconstrictive, or other agent is infused through the catheter into the targeted area. The infusion rate and volume are determined based on the specific medication and clinical guidelines.
  • Step 5: Catheter Removal and Vessel Repair - After the medication has been successfully administered, the catheter is carefully removed. The puncture site in the blood vessel is then repaired to ensure proper healing and to prevent complications such as bleeding or infection.

3. Post-Procedure

Following the transcatheter therapy procedure, patients are typically monitored for any immediate complications, such as bleeding or adverse reactions to the infused medication. Post-procedure care may include instructions for activity restrictions, pain management, and signs of potential complications that should be reported to healthcare providers. Patients may also require follow-up appointments to assess the effectiveness of the treatment and to monitor the vascular site for proper healing. It is essential to ensure that the patient understands the importance of adhering to post-procedure guidelines to promote optimal recovery and outcomes.
