Official Description

Noninvasive physiologic study of implanted wireless pressure sensor in aneurysmal sac following endovascular repair, complete study including recording, analysis of pressure and waveform tracings, interpretation and report

Common Language Description

A noninvasive physiologic study, as described by CPT® Code 93982, involves the assessment of a wireless pressure sensor that has been previously implanted in an aneurysmal sac during an endovascular repair procedure. This study is crucial for monitoring the condition of the abdominal aortic aneurysm (AAA) post-repair. The procedure is designed to be performed at regular intervals, either yearly or semi-annually, to detect any potential complications that may arise, such as repressurization of the aneurysm or the occurrence of an endoleak. The wireless sensor, which is approximately the size of a grain of rice, is engineered to measure critical parameters including pressure, flow, and temperature within the aneurysmal sac. This advanced device utilizes acoustic wave technology, allowing it to transmit data effectively through various tissues, including soft tissue, bone, and fluid, without being absorbed. Its design requires minimal energy, ensuring a high signal-to-noise ratio, which is essential for accurate readings from deep anatomical locations. Notably, the sensor operates without a battery, antenna, or connecting leads, enhancing its reliability and ease of use. An external unit is employed to power the implant and to receive data directly from it. During the study, a trained technologist collects the data from the sensor, which is subsequently analyzed by a physician. This analysis includes reviewing waveform tracings generated by the sensor and measuring the pressure within the aneurysm sac from various positions using the external unit. The physician compares these readings for pulsatility and evaluates them against data from previous studies, including presurgical assessments and immediate post-operative evaluations. Any significant changes in the raw pressure measurements, which are normalized to the brachial systolic pressure, are meticulously documented. The findings are compiled into a comprehensive report, which includes identified waveforms and pressure measurements that are critical for ongoing patient management and care.

1. Indications

The noninvasive physiologic study of the implanted wireless pressure sensor is indicated for the following conditions:

Monitoring Post-Endovascular Repair: This procedure is performed to monitor patients who have undergone endovascular repair of an abdominal aortic aneurysm (AAA) to ensure the integrity of the repair and the absence of complications.
Detection of Complications: It is specifically indicated for the early detection of complications such as repressurization of the aneurysmal sac or the presence of an endoleak, which can pose significant risks to the patient.
Assessment of Aneurysm Stability: The study helps in assessing the stability of the aneurysm over time, ensuring that any changes in pressure or flow are identified and addressed promptly.

2. Procedure

The procedure for conducting a noninvasive physiologic study using the implanted wireless pressure sensor involves several key steps:

Data Collection: A trained technologist begins by obtaining data from the implanted wireless pressure sensor. This involves activating the sensor and ensuring that it is functioning correctly to capture accurate measurements of pressure, flow, and temperature within the aneurysmal sac.
Waveform Tracing Analysis: The technologist collects waveform tracings generated by the sensor. These tracings provide critical information regarding the pulsatility and hemodynamic status of the aneurysm sac. The data is recorded and prepared for review.
Pressure Measurement Comparison: The physician reviews the collected data, comparing the current waveform tracings and pressure measurements with those obtained from previous studies, including presurgical and immediate post-operative assessments. This comparison is essential for identifying any clinically significant changes.
Normalization of Measurements: Raw pressure measurements are normalized to the brachial systolic pressure to ensure consistency and accuracy in the evaluation. This step allows for a standardized comparison across different time points.
Report Generation: After thorough analysis, the physician dictates a report summarizing the findings. This report includes identified waveforms and pressure measurements that are clinically relevant, ensuring that all significant changes are documented for future reference.

3. Post-Procedure

Post-procedure care following the noninvasive physiologic study involves monitoring the patient for any immediate reactions to the study. Patients may be advised to follow up with their healthcare provider to discuss the results of the study and any necessary adjustments to their treatment plan. The physician will review the report generated from the study, which includes detailed analysis and comparisons to previous measurements. Ongoing monitoring may be recommended at regular intervals to ensure continued stability of the aneurysm and to detect any potential complications early. It is essential for patients to adhere to follow-up appointments to maintain optimal health outcomes.
