Vascular Doppler Diagnostics in India: Regional Perspectives and Applications

Vascular Doppler ultrasound is an absolutely painless procedure, and it utilizes sound waves of very high frequency to quantify the blood flow through different parts of the body, like arteries and veins. The situation is such that larger cities in India have already considered it a normal diagnostic tool.

The incidence of diabetes in India exceeds 77 million, and about 18% of these patients suffering from it may also have peripheral arterial disease (PAD), making Doppler screening a necessity. Another factor making carotid Doppler screening more urgent is the fact that stroke is the 4th leading cause of death in India.

Kody Medical Electronics is a well-established manufacturer of vascular Dopplers and related diagnostic devices in India, headquartered in Chennai. They have more than three decades of experience in this field. Their sales and service network covers the regions of Chennai, Coimbatore, Bengaluru, Hyderabad, Mumbai/Pune, and Delhi; hence, technical support and service to local customers are provided quickly.

Chennai & Tamil Nadu

Kody Medical’s main office is located in Thiruvanmiyur, Chennai. High diabetes rates in Chennai and Tamil Nadu create the need for vascular screening. Local diabetic foot clinics regularly carry out ABI and Doppler studies, and it has been found through studies that about 8% of urban diabetics in Chennai have peripheral arterial disease.

In fact, the basic tools in the hospitals and vascular labs of Chennai are handheld Dopplers and ABI devices. The Kody office in Chennai is responsible for on-site demonstrations, quick service, and technical training for the vascular Doppler users in Tamil Nadu.

Bengaluru (Karnataka)

The healthcare industry in Bengaluru is growing fast, and it includes major hospitals and specialty cardiac centers. They all depend on Doppler ultrasound for vascular diagnostics. Peripheral and carotid Doppler exams are a part of the routine procedure in diabetic as well as stroke-risk screening programs.

Clinics in the city often use Kody’s portable Doppler probes and ABI/PVR units. The presence of a large number of vascular surgeons and imaging centers has resulted in Bengaluru’s strong demand for Doppler systems in private hospitals and diagnostic labs. The regional representative of Kody offers his support in training, installing, and maintaining the devices all over Karnataka.

Hyderabad (Telangana)

Cardiology, diabetes treatment, and transplant surgeries are the main medical areas for which Hyderabad serves as a regional center. Vascular suites fully equipped with Doppler systems are available in the major hospitals. Hypertension and kidney disease are prevalent in the area, which is why Doppler scans of renal and carotid areas are so important. The use of vascular Doppler machines, including the adoption of ABI and PVR systems, is common for diabetic foot screenings, DVT detections, and transplant evaluations. Kody, through its regional service teams, provides full technical support to Telangana and Andhra Pradesh.

Mumbai & Pune (Maharashtra)

Mumbai and Pune cities host some of the biggest hospital networks and diagnostic chains in India. Vascular screening to prevent diabetes side effects turns out to be an important service in Maharashtra due to the large diabetic population. Peripheral arterial, venous, carotid, and renal Doppler studies along with ABI/PVR tests are the routine procedures of hospitals and diagnostic centers in Mumbai and Pune. Kody’s regional offices offer local supply, calibration, and after-sales support to the Doppler systems throughout Maharashtra.

Delhi NCR (Delhi, Gurgaon, Noida)

The National Capital Region of Delhi, which is the largest metro in India, has high-quality cardiac and stroke care centers. People are very aware of the importance of vascular health, and the majority of the most comprehensive packages for stroke-risk testing include carotid Doppler as one of the tests.

Doppler ultrasound is a common method to screen for PAD, DVT, and carotid artery stenosis by hospitals and imaging centers in Delhi, Gurgaon, and Noida. The Kody office in Delhi provides support to hospitals and diagnostic labs across North India and thus facilitates the prompt availability of service and equipment.

Key Vascular Doppler Applications

Peripheral Arterial Doppler (PAD / Diabetic Foot)

The detection of blockages in leg arteries through this test is crucial for the early detection of PAD, which is found among almost 20% of the diabetes patients in India. In addition to Doppler studies, diabetes care clinics and vascular labs regularly conduct the ABI measurement as a crucial component of this assessment. The early detection of decreased foot blood flow can help avoid ulceration and amputation of the foot in diabetic patients.  Kody’s handheld Dopplers and ABI/PVR systems are becoming widely popular in diabetes care clinics and vascular labs throughout India.

Venous Doppler (DVT/varicose veins)

The painless and easy blood flow test using venous Doppler indicates the Valvular insufficiency conditions in Varicose veins through Venous reflux study. It uses a PPG probe affixed adjacent to the posterior tibial artery, at or above the ankle. Dorsiflexing the foot acts as a pump for Venous augmentation. Recovery time is the time required for Venous refilling to occur. Venous Reflux is used to assess Valvular competence.

1. Normal refill time will exceed 21 seconds
2. Refill time between 18 and 21 seconds is questionable. Repeat the test
3. If refill time is less than 18 seconds, a venous condition may exist.

This above interpretation on early diagnosis will eliminate the possible venous complications in future.

Carotid Doppler (Stroke Risk Assessment)

The carotid Doppler studies monitor blood flow in the neck arteries with the purpose of identifying any narrowing or occlusions that could potentially lead to a stroke. Since strokes are a major cause of death and disability in India, ultrasonic carotid screening becomes necessary for patients with high blood pressure, diabetes, and heart problems. The Kody Doppler units function seamlessly with the bidirectional probes that are deployed in carotid blood flow parameters like blood velocity, volume etc, thereby extending support to hospitals and diagnostic centers throughout the nation.

Abdominal/Renal Doppler

Doppler assessment of renal and abdominal organs provides information on blood flow to the kidneys and large vessels in the abdomen, respectively. These tests are of utmost significance in the diagnosis of renal artery stenosis and the evaluation of graft function post-transplant. Given India’s numerous kidney-related issues, transplant and nephrology centers must use Doppler assessment. Kody offers Doppler ultrasound devices and probes for surgical procedures.

ABI & PVR Testing

Ankle-Brachial Index (ABI) and Pulse Volume Recording (PVR) are necessary ways to measure blood flow to the legs and check the health of the arteries. The automatic ABI systems of Kody’s Smartdop series supply waveform data and accurate measurements, which are important for diabetic foot screening and monitoring of vascular health. The usage of these systems is common in the most advanced vascular labs in the states of Tamil Nadu, Maharashtra, Delhi and all over India.

Intraoperative Doppler/Volume Flow Measurement

The intraoperative Doppler probes enable the surgeons to assess the blood supply during the vascular, cardiac, and microsurgical operations via the real-time monitoring of blood flow. These instruments not only ensure the success of the graft but also ensures proper blood flow in the vessels, which in turn leads to fewer complications after surgery. Kody’s surgical Doppler machines are the first choice for major hospitals when it comes to monitoring accuracy intraoperatively in vascular and reconstructive surgery.

Kody Medical’s Nationwide Support

Kody Medical’s strong foothold in South India—service hubs are in Chennai, Coimbatore, Bengaluru, and Hyderabad—allows the company to provide fast technical support, calibration, and training for users.
