SMA Stenting

SM Stenting
The vascular surgeon inflates a small balloon inside a restricted mesenteric artery during this surgery, which is sometimes done at the same time as the angiography. The surgeon may install a stent, a thin metallic mesh tube that supports the artery's walls and maintains the blood arteries open, after expanding the artery using angioplasty.  SMAS (superior mesenteric artery syndrome) is a digestive disorder in which the duodenum (the first part of the small intestine) is squeezed between two arteries (the aorta and the superior mesenteric artery). The duodenum is partially or completely blocked as a result of this compression. SMAS is a medically curable cause of small intestinal obstruction with a positive outcome. The least risky treatment approach is conservative medical treatment combined with nutritional rehabilitation, which is successful in the majority of patients. The vascular surgeon inflates a small balloon inside a restricted mesenteric artery during this surgery, which is sometimes done at the same time as the angiography. The surgeon may install a stent, a thin metallic mesh tube that supports the artery's walls and maintains the blood arteries open, after expanding the artery using angioplasty. The placement of a stent in the SMA may be an option for treating mesenteric ischemia caused by aortic dissection, particularly if there is a lack of a doctor with adequate aortic stent grafting skills, no aortic stent-graft device in the hospital and a long wait for delivery of an aortic stent graft device to the hospital. However, because the primary entrance rupture is not repaired with this treatment, careful observation of the patient or preparation for aortic stent grafting is required. In the middle of the digestive tract is the superior mesenteric artery (midgut). It comes from the aorta, which runs between the celiac and renal arteries.

Fluid resuscitation, total parenteral nutrition, placement of a nasoenteric tube past the obstruction for enteric feedings, tiny meals, and positional eating are among the medical treatments for SMA syndrome.  

What is a mesenteric angiography and how is it performed?

An artery is pierced with a needle. A catheter is a tiny flexible tube that is passed through the needle. It is threaded into the artery and then up through the main vessels of the abdomen until it reaches a mesenteric artery. X-rays are used as guidance by the doctor.

How can you know if you have mesenteric ischemia?

Ø Angiography. A long, thin tube called a catheter is placed into a groyne artery for this examination.

Ø CT angiography is a type of angiography that uses a computer This test is comparable to angiography, except it uses 3-D images that are led by a computer rather than angiography.

Ø MR angiography is a type of angiography that uses magnetic resonance imaging to

Ø Ultrasound with Doppler.

Ø Tests on the blood.

 The angle between the AA and the SMA can be measured via CT angiography or MRI. The usual angle is 25–60 degrees, but it is lowered to 7–22 degrees in people with SMA syndrome.

 CT is a radiographic characteristic

The SMA is frequently enlarged on non-contrast CT. In acute cases, postcontrast pictures frequently reveal a vascular flap. Increased attenuation of the fat plane around the SMA can also occur in an acute situation.

 Prognosis and treatment

There are a variety of treatment options available, including conservative care, surgical revascularization, and endovascular therapy 8. The prognosis varies, and it might be fatal in some cases.

Stents are divided into two types: bare-metal stents and drug-eluting stents. The latter is more commonly utilized and is coated with drugs to help keep a blocked artery open for longer.

For the Acute Stroke Mechanical Thrombectomy, Dr. Sandeep Sharma is the best radiologist to consult. He is an expert in both suction retrieval and stent retrieval and uses both techniques in perfect combination

Bilateral Varicocele Embolization

Image
Varicoceles are not life-threatening, however, they can be linked to serious illnesses in rare cases. If a varicocele arises on the right side of the abdomen rather than the left, for example, make sure there is no mass or other abnormalities in the abdomen that could be causing it. Blood is transported back to the heart via veins throughout the body. They usually feature valves to keep the blood flowing in the right way. When the valves in the testicular vein don't work properly, blood can pool in the scrotum, resulting in a varicocele. They commonly happen on the left side, and they're caused by the testicular vein's path through the abdomen. Varicocele is a frequent condition that is not hazardous. In fact, a varicocele affects 15% of all adult men. Many men's varicocele will go undiscovered for the rest of their lives or may create no complications at all. Varicoceles affect about 20% of teens, therefore a portion of them will most likely resolve on their own. The

LIVER ABSCESS DRAINAGE

Image
A pus-filled patch of fluid within the liver is known as a pyrogenic hepatic abscess. Pyogenic denotes the production of pus. A liver abscess can arise from a number of various causes, including a blood infection, an abdominal infection, or an infected abdominal injury. An abscess in the liver is a serious infection. It has the potential to cause major issues and even death. It can cause tissue damage in the spot where it is discovered. Fever, discomfort, nausea, diarrhoea, and loss of appetite are all possible symptoms. The whole first treatment for an amebic liver abscess is amebicidal medicines. The medication of choice is metronidazeole. The size of the abscess is a key determinant in deciding how well medical therapy works. Other treatment options include percutaneous needle aspiration and/or catheter drainage.  The type of abscess that occurs is influenced by one's age. People in their 40s and 60s are more likely to have a liver abscess that is not caused by trauma.  The foll

What is Interventional Radiology?

Image
  The medical technology has done so much progress in the past one decade that it’s sometimes surprising. Interventional radiology is one such amazing medical innovation that involves medical imaging which guides minimally invasive surgical procedures that help in diagnosis, treatment and cure of many different kinds of treatments. For imaging, the modalities used are ultrasound, MRI, CT and fluoroscopy. Why Interventional Radiology? Many surgeries are now being switched to the method of Interventional radiology and that is because the IR procedure is known to be more effective compared to their traditional surgical counterparts. This method is any day less risky, less painful and even costs you way lesser comparatively. These reasons are influencing people to prefer the IR treatment methods and hence it is starting to expand all across the world. How does Interventional Radiology work? There are various broad range procedures performed under Interventional Radiology like treating tumo
