Cervical Lymph Node Multiple Biopsies In An Adolescent

Image
Cervical nodes that are swollen are rarely a symptom of malignancy.  However, non-painful enlargement of one or more lymph nodes, particularly those in the neck, is a crucial warning sign of lymphoma, including Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) (NHL) Lymph nodes swell when viruses, dangerous bacteria, and damaged cells are trapped inside, and lymphocytes, the white blood cells that fight infection, strive to eliminate them. Swollen lymph nodes, on the other hand, can be an indication of malignancy, including lymphoma, a type of blood cancer. An incision is made over the swollen lymph node, and the node is dissected out of its surrounds with care to tie off or cauterise veins and lymphatic channels linked to it while under general anaesthesia. After that, the lymph node is transported to the lab for examination. Many infectious, autoimmune, metabolic, and malignant diseases affect the lymph nodes, which are an important part of the body's immune system. The cervi

TACE For Large Arterio Portal Shunting

Image
Shunts between the portal venous and hepatic artery systems within the liver are known as intrahepatic arterioportal shunts. They may be the cause of reversible portal hypertension. The size and other underlying diseases will determine the clinical characteristics. Small shunts may go symptomless.  ·  The following are the several types of intrahepatic vascular shunts: ·  Transtumoural shunt occurs in hepatocellular carcinoma and, to a lesser extent, hepatic hemangioma due to improper communication between the tumour's feeding artery and draining vein, resulting in enhanced vascularity surrounding the tumour seen as temporary hepatic attenuation abnormalities (THAD) ·  The portal vein may exhibit an early increase on a dynamic arterial scan without the splenic and superior mesenteric veins, which are its main tributaries. Radiographic characteristics In general, the symptoms are comparable to those of cerebral infarction in any other location. As a result, these characteristics are

Basilar Top Aneurysm

Image
Aneurysms of the basilar trunk artery are extremely rare, accounting for only 2.1 percent of all intracranial aneurysms. They are most commonly diagnosed in persons over 60, have a slight male predominance, and are linked to high morbidity and mortality. A type of posterior circulation cerebral aneurysm that accounts for just a small percentage of all aneurysms, with the majority occurring in the anterior circulation. Cerebral aneurysms are commonly found near bifurcations, such as this one, where the posterior cerebral artery is immediately posterior.   Ruptured basilar tip aneurysms can cause deadly subarachnoid hemorrhage (SAH), with a fatality rate of up to 23%. A big basilar artery aneurysm presenting as a stroke is extremely uncommon. The consequences and prognostic implications of this disorder necessitate examination and recognition.  Fusiform aneurysms are most common in severely atherosclerotic basilar arteries, and atherosclerotic disease is most often the cause of mortalit

Aneurysm Flow Diverter Treatment

Image
What does flow diversion entail? Instead of inserting a device inside the aneurysm sac, as with coiling, a flow diversion device is placed in the parent blood artery to divert blood flow away from the aneurysm.   What is the procedure for flow diversion/Pipeline? Slide for flow diversion The Pipeline stent is being inserted. A microcatheter is steered through the aneurysm without needing to enter it during a flow-diversion/Pipeline treatment . Then, in the parent blood vessel where the aneurysm is situated, the flow-diverting device (Pipeline Embolization Device) is deployed across the neck of the aneurysm. The blood flow to the aneurysm is reduced almost immediately, and the aneurysm closes completely between 6 weeks and 6 months after the treatment. Reasons for performing flow diversion An unruptured brain aneurysm may be treated using a flow diversion technique. Flow diversion is one way for avoiding the most risky phase of endovascular aneurysm treatment: entering the aneurysm. By

Micro PTBD And Stent Deployment

Image
Alternative therapies for malignant obstructive jaundice include percutaneous transhepatic biliary drainage (PTBD) and stenting. For the treatment of malignant obstructive jaundice, PTBD and stenting have shown good efficacy, with few complications and reduced pain. For the treatment of malignant obstructive jaundice, PTBD and stenting have demonstrated good efficacy, with few complications and reduced pain. Primary biliary carcinomas, such as cholangiocarcinoma and gallbladder cancer, and extra-biliary carcinomas, such as ampullary, pancreatic, and gastric cancer, as well as hepatocellular carcinoma, can all produce malignant obstructive jaundice.  Percutaneous transhepatic biliary drainage (PTBD) and stenting are two new treatments for malignant obstructive jaundice that have good clinical efficacy, few side effects, and cause minimal patient pain. For older patients, individuals with inoperable malignant obstructive jaundice, and patients with postoperative recurrence, diabetes, or

Lumbar Sympathectomy in a Case with Foot Arterial Blockage Causing Intermittent Claudication

Image
A chemical sympathectomy is  an injection on the sympathetic nerves which run down the front of the backbone, close to, but outside the spinal column . Lumbar sympathectomy is a surgery that helps dilate tiny blood arteries in the skin and subcutaneous tissues. This can help reduce pain and improve circulation by severing the nerves that cause artery constriction. What is the purpose of a lumbar sympathectomy? Lumbar sympathectomy is used to treat leg and foot pain caused by a lack of blood supply, as well as to help leg and foot ulcers heal. To cure excessive perspiration in the foot and to reduce leg and back pain caused by spinal canal stenosis. Raynaud's disease, arteriosclerosis, and thromboangiitis obliterans have all been treated by lumbar sympathectomy in humans. In individuals with resistant hypertension, catheter-based interventional techniques that interrupt the renal sympathetic neural system have demonstrated encouraging results in improving blood pressure control.

LIVER ABSCESS DRAINAGE

Image
A pus-filled patch of fluid within the liver is known as a pyogenic 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, diarrhea, 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 metronidazole. 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 follow

Vertebral Hemangioma Alcohol Ablation 

Image
Vertebral hemangiomas are benign vascular tumours of the spine that affect around ten percent of the population. They are frequently asymptomatic and are discovered by chance due to their distinctive features on MRI. If a hemangioma has unrestrained bleeding, it might be severe. For vertebral hemangiomas , alcohol ablation is an effectual treatment choice. Hemangioma discomfort can be effectively treated with radiation therapy. Surgery, radiotherapy into hemangiomatous vertebrae have all been used to treat vertebral hemangiomas. Vertebral hemangiomas appear as lucent patches separated by bony trabeculae on CT scans. V ertebral hemangiomas are congenital vascular abnormalities, not actual tumours. Using CT-guided alcohol ablation, about 85 percent of symptomatic vertebral hemangiomas can be improved significantly.    The non-surgical treatment for hypertrophic cardiomyopathy is alcohol septal ablation. The diagnosis of a vertebral hemangioma is critical and, in some situations, difficul

Acute Stroke Mechanical Thrombectomy

Image
Mechanical thrombectomy is indicated for patients who have an acute ischemic stroke caused by a large artery occlusion in the anterior circulation and can be treated within 24 hours of last known good health (ie, at neurologic baseline), regardless of whether they have received intravenous thrombolytic therapy for the same. Mechanical thrombectomy is a minimally invasive technique in which an interventional radiologist removes a clot from a patient's artery using specialised equipment. The doctor uses fluoroscopy, or continuous x-ray, to guide devices through the patient's arteries to the clot, which is then extracted in one piece. For patients with ischemic stroke (IS) who have a proximal major cerebral artery occlusion within 6 hours of onset of symptoms, mechanical thrombectomy (MT) is the standard-of-care treatment. In patients with anterior circulation ELVO and an NIHSS score of 6 [class I, level A], thrombectomy is recommended. When coupled with disabling symptoms [class

Bony metastases preoperative embolization

Image
For hyper vascular tumours like renal cell carcinoma and thyroid carcinoma, preoperative embolization of metastases was first described. The main goal of this systematic review was to find long bone metastases that could benefit from preoperative embolization to reduce perioperative blood loss and blood transfusions. Because any less than total devascularization increases blood loss and red blood cell transfusion during surgery, interventional radiologists should pursue and embolize every feeder to the metastasis. When cancer cells move from their initial place to a bone, this is called bone metastasis.   Almost all cancers can move to the bones (metastasize). However, some cancers, such as breast cancer and prostate cancer, are more prone to spread to the bones. In the treatment of bone metastases, transcatheter embolization is effective and reliable.    When surgery is planned, a catheter can be inserted into an artery (typically in the leg, as for a cardiac angiography) and a
