Advanced Laser Treatment in Cancer
Interventional Radiology (IR) plays a critical role in cancer care, from diagnosis to minimally invasive treatments. Through laser treatment in cancer, IR enables cancer treatment specialists in Kolkata like Dr. Avik Bhattacharyya to perform precise procedures such as transarterial chemo-embolization and radiofrequency ablation. These treatments help target tumors and manage complications like pain, organ obstruction, and venous thrombosis. With minimally invasive techniques, IR offers safer cancer management, allowing quicker recovery and reducing risks, making it a preferred choice for advanced cancer treatment in Kolkata.
Interventional Radiology in the Diagnosis of Cancer
Appropriate treatment of malignancy is dependent on a timely definitive diagnosis and on accurate staging of disease. While non-invasive imaging techniques have improved assessment and staging for cancer, histologic confirmation remains the gold standard for definitive diagnosis of many tumours. Biopsies to establish histological diagnosis are increasingly performed using minimally invasive techniques by interventional radiologists.

Central Venous Access
An integral part of care of the cancer patient is intermediate and longer-term vascular access as a means of medication, chemotherapy, or parenteral nutrition administration, as well as allowing repeated blood sampling without need for venepuncture.
Arterial Embolisation Techniques
Minimally invasive image-guided cancer treatments as an adjunct or alternative to surgery are increasingly being used in the management of malignancy. Delineation of the arterial supply of a solid tumour by contrast enhanced CT or MRI facilitates devascularisation of neoplastic tissue by transcatheter embolisation.
Transarterial chemoembolisation (TACE) is a modification of the above technique which is usually applied to hepatic tumours. Following selective hepatic artery catheterisation, a single or combination chemotherapy agent combined with a delivery agent,
Interventional Radiology in the Management of the Complications of Cancer
Malignancy can induce dysfunction of many organs and bodily systems. Though debilitating, a significant portion of these complications are reversible, many by minimally invasive IR methods. Such treatment can relieve symptoms, alleviate pain, and improve operability of patients, thus having a significant positive impact on quality of life.
Biliary Obstruction
The majority of patients presenting with malignant biliary obstruction have an underlying pancreatic neoplasm extrinsically compressing the distal bile duct and can be treated by endoscopic means. Metastatic disease at the hepatic hilar nodes or in the peripancreatic nodes may cause obstructive jaundice from extrinsic pressure on the proximal portions of the biliary tree and may require percutaneous intervention if less invasive endoscopic means fails to achieve adequate biliary decompression. Contrast injection into an intra-hepatic bile duct at percutaneous transhepatic cholangiography will delineate the anatomy of the biliary tree, determining the location of obstruction, and helping to guide intervention. Percutaneous transhepatic biliary drainage (PBD) is an effective method for the primary or palliative management of many biliary abnormalities demonstrated with cholangiography. This procedure involves selective cannulation of the biliary tree with catheter manipulation, then placement of a catheter or stent to facilitate internal or external drainage of biliary flow and so allow decompression of the biliary system .
