VASCULAR AND NON VASCULAR INTERVENTIONAL RADIOLOGY AT SAHARA HOSPITAL
Interventional radiology is a medical sub-specialty of radiology which utilizes minimally-invasive image-guided procedures to diagnose and treat diseases in nearly every organ system. The concept behind interventional radiology is to diagnose and treat patients using the least invasive techniques currently available in order to minimize risk to the patient and improve health outcomes.
Many conditions that once required surgery can now be treated non-surgically by interventional radiologists. By minimizing the physical trauma to the patient, peripheral interventions can reduce infection rates and recovery time, as well as shorten hospital stays.
We in SAHARA HOSPITAL have started doing the interventional procedures, (both vascular and non vascular interventions) for instance
We perform various non biliary interventions e.g. Aspiration of fluid from various parts of the body, for diagnosis of disease in some cases e.g. Abscesses, lungs pleural effusion or gross ascites we treat the problems by single time complete aspiration of abnormal fluid collection or place drains through the skin for prolonged drainage of abnormal fluid collections.
Biliary interventions in patients with liver cancer, bile duct cancer, cholecystitis, cholangitis, or other hepatobiliary pathology there may be obstruction of bile ducts. We routinely perform procedures such as percutaneous transhepatic cholangiography (PTHC or PTC) to image these obstructions, we subsequently treat these conditions using percutaneous transhepatic biliary drainage (PTBD), wherein catheters or stents are placed through the skin into the bile ducts to drain the bile for prolonged periods of time or until surgery.
Dialysis fistula/Arterio-venous graft may fail to “mature”, resulting in the need to image the fistula and potentially relieve any blockages using balloon angioplasty. We have done dialysis fistula angioplasty for the first time in our hospital.
Vascular interventions include diagnostic Digital Substraction Angiography of cranial, abdominal and peripheral vessels to assess the pathology and is followed by treatment in the form of angioplasty / stent placement.
Pre operative embolisation of highly vascular tumors are done by us which include patients with meningiomas, nasopharyngeal angiofibromas and jugular tumors. Recently a pre operative embolisation of the meningioma ( type of brain tumor) was done successfully by us to avoid blood loss during surgery, later surgery was performed by neurosurgeons.
Earlier we have done a large highly vascular pelvic tumor embolisation, which presented to us with bleeding not controlled by other means was successfully controlled after embolisation.
Its a very rare thing to see an intrarenal AV malformation which we have seen in a patient who came to Sahara Hospital with hematuria ( blood in urine) which we successfully embolised by coils and bleeding was controlled.
We have done diagnostic cranial DSA to rule out aneurysm / AVM in cranial vasculature.
Uterine fibroids are non-cancerous growths of the muscular portion of the uterus which may cause pain and heavy bleeding. We are able to perform non-surgical, minimally-invasive treatments of uterine fibroids, called uterine fibroid embolization (UFE), or uterine artery embolization (UAE), using real-time imaging. In this procedure, uterine arteries that supply blood to the fibroid are catheterised using microcatheters and then tiny particles (Polyvinyl alcohol) are released through the catheter to occlude the blood supply of the tumor, causing it to shrink and die.
Fibroid embolization typically requires a hospital stay of one night. On average, 85-90 percent of women who have had the procedure experience significant or total relief of heavy bleeding, pain and/or bulk-related symptoms. Recurrence of fibroids treated by UFE is very rare.
So any patients who do not want surgery for the fibroid and want to retain the uterus can be successfully treated by UAE.
In addition some patients with high blood pressure and /or renal insufficiency, may be having narrowing of their renal arteries. Such patients will benefit by balloon angioplasty or renal artery stenting which we do in our hospital.
Similarly carotid artery stenosis is a condition in which there is a narrowing of the arterial supply of brain which may result in stroke. Stenosis is treated by balloon angioplasty or stenting.
Thus we offer an array of minimally invasive treatment options in various conditions where we can prevent major surgical procedures in a significant number of patients.
Dr. Vivek Singh(MBBS, DNB, MNAMS)has joined us and is performing interventional radiology procedures. Has done residency from Sir Ganga Ram Hospital New Delhi and Senior Residency from Sanjay Gandhi Post Graduate Institute of Medical Sciences, SGPGIMS, Lucknow.
He has specialized in vascular and non vascular intervention and has experience in diagnostic as well as therapeutic work. He has performed several procedure at SAHARA HOSPITAL such as tumor embolisation, balloon angioplasty, biliary stenting, beside various catheter based procedures.
