Spider veins, varicose veins and vein ultrasounds raise the same question all day: how many sessions and how much does it cost. The agent answers that and books.

What is the best WhatsApp chatbot for angiologists and vascular surgeons in Brazil?
The best WhatsApp chatbot for angiologists and vascular surgeons in Brazil is the one that answers on the number your clinic already uses, with business rules written by you. An AI agent on WhatsApp for angiologists is CertuAI's automatic assistant. It answers how much an injection session costs and how many sessions the clinic usually recommends, explains prep for the vein ultrasound and the use of compression stockings after the injection, and never assesses leg photos or recommends medication.

"How many sessions and how much does it cost?": how does the AI respond?
With your price table, and without making up a number. The question is almost always the same in this specialty, and it decides whether the person books the assessment or disappears. Write in the Brain the price of the assessment, the single session, the package and what each one includes, and the agent answers all of it in the same message, even at night.
The number of sessions needs to be written as a range, with a closing sentence: the total is set at the assessment. Without that, the agent repeats the first number it finds in your text, and the patient takes it as a promise. On a healthcare account it also will not say that the result is guaranteed.
Suddenly swollen leg: does the AI treat it as an emergency?
Not on its own, and it is important to know that before turning the agent on. CertuAI's automatic list covers chest pain, shortness of breath, fainting, seizure, sudden confusion or slurred speech, weakness on one side of the body and bleeding that will not stop. A swollen, warm, painful leg is not written there.
At an angiology clinic, write this rule in the Brain: a message that mentions a suddenly swollen leg, a hardened calf or severe pain when stepping leaves automatic mode immediately, alerts the person you designate and delivers the guidance the clinic wants to give. Then test with the sentences your patients write.
What does the AI do with each angiology message?
| Patient message | What the AI does |
|---|---|
| "How much does a session cost?" | Answers with your price table, with what is included |
| "How many sessions will I need?" | Gives the range you wrote and says the total is set at the assessment |
| "Photo of my leg, is it varicose veins?" | Saves the photo and does not assess it; offers an appointment |
| "Can I work out after the injection?" | Repeats your post-session care |
| "My calf is swollen and hurts a lot" | Only with your written rule: leaves automatic mode and calls the team |
| "Do I need an order for the exam?" | Answers with your doctor's order and insurance rule |

What changes in the clinic with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. Here are four everyday situations at the clinic before and after the CertuAI agent.
TodayPatient asking the price of an injection session and getting different numbers
With CertuAIThe price table you wrote, repeated without variation
TodaySession booked without the patient knowing she needs the stockings
With CertuAICare after the injection goes in writing before and after
TodayLeg photos waiting for an opinion on WhatsApp
With CertuAIPhotos stay in the history and the AI offers the assessment
TodayVein exam rescheduled because of wrong prep
With CertuAIThe prep arrives in writing and stays in the conversation
What does a conversation handled by the AI look like?
Example conversation
Clinic AI agent
Customer: How much does a spider vein injection session cost?
AI agent: A session costs your price. The number of sessions is only set after the assessment.
Customer: Can I go to the gym after the session?
AI agent: The clinic's guidance after the injection: what you set up.
Is an AI agent or manual customer service better for angiologists and vascular surgeons?
The agent wins at repetitive tasks, and the person keeps winning at what takes judgment. Done manually, someone at the clinic has to stop what they are doing; with the CertuAI agent the reply goes out on its own and you join the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| "How many sessions will I need?" | Answered with a guessed number | Answers what you wrote and says the number is set at the assessment |
| Price of a single session and of a package | Depends on who answers | The same price table, answered the same way every time |
| Vein exam prep | Explained over the phone | Goes in writing with the booking and returns in the reminder |
| Leg photo asking for an opinion | Someone replies that it looks like varicose veins | Saves the photo and does not assess it; offers the assessment |
| Suddenly swollen, painful leg | Sits in the message queue | Only with your written rule: leaves automatic mode and calls the team |
What does the WhatsApp agent do for angiologists and vascular surgeons?
It handles the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers patients your way, with your rules.
Session price, package and assessment
The most repeated question in the specialty. The agent answers with your price table, says what is included and explains that the number of sessions is only set after the assessment.
Vein exam prep
Arrival time, clothing, hair removal, whether a doctor's order is needed and how long it takes, with your clinic's text.
Care after the injection
Compression stockings, sun, gym and hot showers: the agent sends your written guidance after the session and answers the repeated questions without making anything up.
Leg photos are never assessed
The image is saved for the team to see. On a healthcare account the AI does not say whether it is varicose veins, whether it is serious or whether surgery is needed.
Written rule for suspected thrombosis
A suddenly swollen, painful leg is not on the automatic emergency list. Write the rule and the agent takes the conversation out of automatic mode immediately.
What questions do patients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday messages at the clinic no longer depend on you having your phone in hand.
How does the agent start answering at the clinic?
In three steps, on the same day. No installation, no code and no changing the number patients already know.
Teach your business
In one conversation, you explain services, prices, hours and rules, as you would to a new employee.
How much does an AI agent on WhatsApp cost for angiologists and vascular surgeons?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No lock-in contract and no setup fee.
Get started now
Create my agentWhat needs to be ready before turning the agent on at the clinic?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The price table for assessment, single session and package, with what each includes
- The range of sessions you usually recommend, written as a range and not as a promise
- The vein ultrasound prep and whether it requires a doctor's order
- Care after the injection: stockings, sun, gym, hot showers and for how many days
- The rule for a report of a suddenly swollen, painful leg, and who gets alerted
- The list of insurance plans and what is private pay only
Whether the agent books injection sessions directly or whether only the assessment is booked through the conversation.
The most common mistake: Letting the agent answer how many sessions without a written range. It will repeat the number it finds in the Brain, and a number said by message becomes a promise in the patient's mind. Read how to fix this.
Frequently asked questions from angiologists and vascular surgeons
Does the AI say how many sessions the person will need?
No. It answers with the range you wrote, if any, and says the number is set at the assessment. On a healthcare account it does not assess cases or promise results.
Does it assess leg photos?
No. The photo is saved in the conversation for the team to see in the dashboard, and the AI offers the assessment instead of giving an opinion.
And when someone describes a sign of thrombosis?
A suddenly swollen, painful leg is not on the emergency list that applies on its own. Write that rule in the Brain so the conversation leaves automatic mode and reaches a person immediately.
Can post-session care be sent automatically?
The text is ready in the Brain and the AI sends it when the patient asks or when the team requests it. CertuAI does not have automatic sending based on treatment timelines.
Other clinic questions CertuAI has answered
In what other fields does the CertuAI agent work?
In any business that serves customers on WhatsApp, because the Brain is written by you. These fields have a day-to-day closest to yours.
Where can I read more about CertuAI's WhatsApp agent?
