Vascular

Vascular

At MIHS, we are experienced with a spectrum of surgeries and procedures to treat a variety of vascular conditions. Our operating room and interventional radiology suite provide a versatile environment for our vascular specialists to perform complex surgeries and procedures. Advanced x-ray and 3D imaging equipment allows the vascular team to view the structures and repairs inside the body in near real-time. 

 

Here is a list of the procedures we perform using our advanced technology and dedicated interventional radiology suite:

Abdominal aortic aneurysm repair
Abdominal aortic aneurysm repair is surgery to fix a widened part in your aorta. An aortic aneurysm is when part of the aorta becomes too large or balloons outward.

Aorta bifemoral bypass graft
Aorta bifemoral bypass surgery is used to redirect blood around a diseased area in the abdomen and groin through a synthetic graft. To achieve this, the graft must be sewn above and below the diseased area. The artificial blood vessel is formed into a Y shape and the single end of the Y is sewn on the aorta. The two split ends of the Y are sewn below the blocked or narrowed areas.

Aortic descending thoracic aneurysm repair
An aneurysm close to the aortic valve may require the valve to be repaired or replaced. The aorta is the largest blood vessel in the body, so the burst of a descending thoracic aortic aneurysm could cause life-threatening, uncontrolled bleeding. If surgery is needed on the aortic arch, the procedure is approached from the front chest area.

Arteriovenous fistula repair
An arteriovenous (AV) fistula is an abnormal connection between an artery and a vein.

Axilo femoral artery bypass graft
An Axilo femoral artery bypass graph is a method of surgical revascularization used for patients who have insufficient blood supply to lower limbs and in whom normal placement of a graph is not possible.

Atrial Septal Defect / Patent Foramen Ovale Closures
An Atrial Septal Defect (ASD) is a hole between the two upper chambers of the heart or atria. This happens in fetal development when the wall between the collecting chambers does not completely close and leaves a hole.

The closure of an ASD is performed using a special device attached to a catheter. The catheter is inserted into a vein in the leg and advanced into the heart and through the hole in the atria. The device is slowly pushed out of the catheter (like an umbrella) allowing each side of the device to open and cover each side of the hole, like a sandwich, closing the hole or defect. When the device is in proper position, it is released from the special catheter. Over time, heart tissue grows over the implant, and it becomes part of the heart. The ASD closure procedure is monitored by X-ray and an ultrasound.

A Patent Foramen Ovale (PFO) is a hole between the two upper chambers of the heart or atria but smaller than an ASD. The procedure to close a PFO is like the ASD procedure. The differences are that in the PFO closure the right atrial disk (the device covering the hole on the right side of the heart) is larger and the diameter of the connection between the two disks is smaller than the ASD.

Carotid Doppler
The Carotid Doppler exam uses sound frequency to produce images of the carotid arteries on a viewing screen. The carotid arteries are in the neck and supply blood to the brain. The ultrasound machine sends out high frequency sound waves and receives the echoes bouncing off the blood vessels to form images. These images help the doctor determine if the arteries have any possible blockages in them.

Echocardiogram
An echocardiogram (also called an echo) is a type of ultrasound test that uses high-pitched sound waves that are sent and received through a device called a transducer. The device picks up echoes of the sound waves as they bounce off the different parts of the heart. These echoes are turned into moving pictures of the patient’s heart that can be seen on a video screen.

The different types of echocardiograms are:

Doppler echocardiogram: This test is used to look at how blood flows through the heart chambers, heart valves and blood vessels. The movement of the blood reflects sound waves to a transducer. The ultrasound computer then measures the direction and speed of the blood flowing through the patient’s heart and blood vessels. Doppler measurements may be displayed in black and white or in color. This test is done to assess potential leaks in your valves.

Transthoracic echocardiogram (TTE): This is the most common type of echocardiogram. Views of the heart and valves are obtained by moving the transducer to different locations on your chest or abdominal wall.

Transesophageal echocardiogram (TEE): The probe is passed down the esophagus instead of being moved over the outside of the chest wall. TEE shows clearer pictures of the heart. Because the probe is located closer to the heart, there is no interference from the lungs and bones of the chest. A sedative and an anesthetic are used on the patient’s esophagus to make them comfortable during this test.

Renal Artery Ultrasound
A renal doppler ultrasound visualizes the renal arteries that provide blood flow to the kidneys. The ultrasound machine used in this test sends out high frequency sound waves and receives the echoes bouncing off the blood vessels to form images. Physicians use these images to detect narrowing of arteries that may hinder blood flow to the kidneys.
