A pigtail catheter is a medical device that is used to drain fluid from various parts of the body. It is called a pigtail catheter because it has a curled end, which resembles the tail of a pig.

Pigtail catheters can be used to drain fluid from the liver in cases of liver abscesses.

Fine-Needle Aspiration Cytology (FNAC) is a diagnostic procedure used to investigate lumps or masses. In this technique, a thin, hollow needle is inserted into the mass for sampling of cells that, after being stained, are examined under a microscope. The sampling and biopsy considered together are called fine-needle aspiration biopsy (FNAB) or fine-needle aspiration cytology (FNAC).

FNAC and biopsy are both diagnostic procedures used to determine the presence of cancerous cells in lumps or masses. FNAC involves the use of a thin needle to extract cells from the mass, while biopsy involves the extraction of sample cells or tissues for examination. Both procedures are commonly used in the diagnosis of cancer and other diseases.

Color Doppler is a technique used in medical ultrasound that allows for the visualization of blood flow direction and velocity within a user-defined area. This is achieved by color-encoding Doppler information and displaying the colors as an overlay on the 2D image of the heart. Color flow Doppler is used frequently in sonography to semiquantitatively assess overall blood flow to a region of interest. Depiction of the general velocity and direction of blood flow within the heart and blood vessels is of primary importance in echocardiography and vascular ultrasound respectively.

Ultrasound facilities that offer Color Doppler services are equipped with specialized ultrasound machines that are capable of performing this technique. These facilities may be found in hospitals, clinics, or standalone imaging centers. One such facility is Atulaya Healthcare, which offers Color Doppler Ultrasound services at their centers in Chandigarh, Jammu, Faridabad, and Ludhiana. They use the Acuson X500 ultrasound system from Siemens, which offers versatility for today’s multispecialty applications. Doppler ultrasound images can help the physician to see and evaluate blockages in blood flow (such as clots), narrowing of vessels, tumors, and congenital malformation.

Balloon-occluded retrograde transvenous obliteration (BRTO) is a technique used by interventional radiologists in the treatment of gastric varices, particularly those with prominent infra-diaphragmatic portosystemic venous shunts (e.g. gastro-renal and gastro-caval shunts).

• The technique is more popular in Asia, where it is a first-line treatment for gastric variceal hemorrhage.
• The modified versions include balloon-occluded antegrade transvenous obliteration (BRTO), coil-assisted retrograde transvenous obliteration (CARTO), and vascular plug-assisted retrograde transvenous obliteration (PARTO).
• The advantages of PARTO include decreased procedure time, decreased post-procedure monitoring and removes the risks associated with an indwelling balloon catheter, i.e. rupture.
• TIPS (Transjugular Intrahepatic Portosystemic Shunt) is another valuable option in controlling esophageal (when endoscopy has failed) and gastric variceal bleeding. TIPS has proven very effective in acutely controlling both esophageal and gastric variceal hemorrhage.

Signs & Symptoms: BRTO is primarily utilized to address the following symptoms and conditions:

• Gastric Varices: Swollen veins in the stomach that can lead to potentially life-threatening bleeding.
• Portal Hypertension: Increased pressure in the portal vein, often associated with liver cirrhosis, which contributes to the development of gastric varices.
• Bleeding: Gastric varices can cause symptoms such as vomiting blood or passing bloody stools.

Investigation and Diagnosis

• Endoscopy
• Imaging Studies

Available Treatments:

1. Balloon-Occluded Retrograde Transvenous Obliteration (BRTO)
2. Endoscopic Therapy
3. Transjugular Intrahepatic Portosystemic Shunt (TIPS)

A Peripherally Inserted Central Catheter (PICC) line is a long, thin tube that is inserted through a vein in the arm and passed through to the larger veins near the heart.

A PICC line is commonly recommended for cancer treatments, liquid nutrition (total parenteral nutrition), infection treatments, and other medications that can irritate small veins. Once your PICC line is in place, it can also be used for

• Blood draws
• Blood transfusions
• Receiving contrast material before an imaging test.

Embolization is a minimally invasive procedure used to treat aneurysms by filling them with material that closes off the sac and reduces the risk of bleeding. It is performed from “within” the artery (endovascular) through a steerable catheter inserted into the bloodstream and guided to the brain.

Embolization of brain aneurysms and arteriovenous malformations (AVM) uses imaging guidance to place small, soft metal coils into an aneurysm to block the flow of blood and prevent the aneurysm from rupturing. It also is used to fill AVMs – abnormal connections between arteries and veins – with liquid embolic agents (similar to fast-sealing glue).

Hysterosalpingogram (HSG) is an X-ray procedure that is used to view the inside of the uterus and fallopian tubes. It is often used to see if the fallopian tubes are partly or fully blocked.

• Fallopian tube recanalization (FTR) is a nonsurgical procedure to clear blockages in the fallopian tubes.
• The procedure is done under sterile conditions to avoid the possibility of introducing infection.
• The overall time to do the procedure is about a half an hour, most of which is spent in getting you comfortable, readying the equipment, and cleaning the skin.
• The actual time spent in evaluating and unblocking the tubes is usually only a matter of minutes and you will be able to leave about a half hour after your procedure is completed.
• The success rate of reopening blocked tube(s) is 95%.

1. Hysterosalpingography (HSG):

HSG is a radiological test that involves the injection of a contrast medium (dye) into the uterine cavity through the cervix. X-ray images are then captured to visualize the uterine and tubal structures, allowing for the assessment of their patency and any abnormalities.

done for-

• Infertility
• Tubal Blockage

2. Fallopian Tube Recanalization (FTR):

FTR is a procedure aimed at reopening blocked fallopian tubes to restore fertility. It can be performed in conjunction with HSG.

• FTR is typically recommended when HSG identifies tubal blockages as a potential cause of infertility.

Microwave Ablation (MWA) is a minimally invasive medical procedure used for the treatment of various medical conditions, including liver tumors and uterine fibroids. It employs microwave energy to heat and destroy abnormal tissues. Below, we provide an in-depth overview of MWA, including its definition, indications, procedure, and potential benefits and considerations for both liver tumors and uterine fibroids.

1. Microwave Ablation (MWA):

Definition: MWA is a medical technique that employs microwave energy to generate heat within tissues, causing thermal ablation or destruction of targeted cells.

Indications:

• • liver
    • hepatocellular carcinoma (HCC)
    • metastases from colorectal cancer
  • pancreas
    • advanced and non-resectable pancreatic tumors – pain control
  • kidney
    • small renal masses
  • lung
    • lung tumors
  • bone
    • painful metastatic lesions
    • osteoid osteoma

Procedure: During MWA, a thin, microwave-emitting probe is guided into the target tissue using imaging guidance, such as ultrasound or CT scans. Once positioned, the microwave energy is delivered to heat and ablate the tissue, causing coagulation and cell death.

Advantages

• • over radiofrequency ablation (RFA)
    • less heat sink effect
      • allowing efficient ablation close to large vessels
    • propagate into fat and calcifications
      • leading to homogeneous coagulation necrosis
    • consistently higher intratumoral temperatures
      • cause larger and fast necrosis
    • faster ablation times
      • lower doses of sedatives might be required
    • larger tumor ablation volumes

In conclusion, Microwave Ablation (MWA) is a minimally invasive procedure used to treat various medical conditions, including liver tumors and uterine fibroids. Its effectiveness and suitability depend on factors like the type, size, and location of the condition being treated. Patients should discuss their specific case and treatment options with their healthcare providers to determine the most appropriate approach.

Transarterial chemoembolization (TACE) is a minimally invasive treatment for liver cancer. It involves injecting a combination of cancer-fighting drugs and an embolic agent into the tumor to block its blood supply, causing the cancer cells to die. This procedure is also known as chemoembolization.

TACE is a specific type of chemoembolization that blocks the hepatic artery to treat liver cancer. Liver cancer tumors can grow new blood vessels (called angiogenesis), which get most of their blood supply from the hepatic artery, while the rest of the liver tissue gets blood from the portal vein. Because of this, doctors can block the hepatic artery to cut off the blood supply to the tumor without affecting the rest of the liver as long as blood is normally flowing toward the liver in the portal vein.
