The mainstay diagnosis of the presenting DVT symptom is an ultrasound with venous Doppler. Ultrasound with venous Doppler rarely identifies the inferior vena cava anomalies present from birth. Difficulties in identifying the congenital stenosis of the vena cava makes diagnosis uncommon. Diagnosis of congenital stenosis of the inferior vena cava can be rarely discovered through abdominal CT examinations, and may present with an array of clinical findings dependent on the drainage patterns of the individuals. Further diagnostic tools such as a transthoracic echocardiogram can reveal the narrowing of the vena cava showing a low velocity of flow. Congenital stenosis of the vena cava can also present as acute respiratory failure and effusion of the right lung on chest X-rays. Treatments
Treatments may not be necessary for the congenital heart defect. If required, treatments can include medication, catheter procedures, corrective surgery and heart transplants dependent on the severity of the defect, age of the patient and patients general health. Symptomatic relief of venous hypertension, associated with the congenital heart defect, can be achieved through surgery as it reduces the likelihood of hepatic vein thrombosis. Intravascular stents are a treatment method for Congenital Stenosis of the Vena Cava. Expandable metallic stents have been used as part of a procedure to dilate and maintain stenotic vena cava. Experiments carried out on mongrel dogs resulted in some failures for dilation and early migration, and occlusion complications in patients. Immediate relief of persisting symptoms occurred in two patients. Double balloon dilation is another technique used to treat stenosis of the vena cava.
Colitis is an inflammation of the colon. Colitis may be acute and self-limited or long-term. It broadly fits into the category of digestive diseases. In a medical context, the label colitis (without qualification) is used if:

The cause of the inflammation in the colon is undetermined; for example, colitis may be applied to Crohns disease at a time when the diagnosis is unknown, or
The context is clear; for example, an individual with ulcerative colitis is talking about their disease with a physician who knows the diagnosis. Signs and symptoms
The signs and symptoms of colitis are quite variable and dependent on the cause of the given colitis and factors that modify its course and severity.Common symptoms of colitis may include: mild to severe abdominal pains and tenderness (depending on the stage of the disease), persistent hemorrhagic diarrhea with pus either present or absent in the stools, fecal incontinence, flatulence, fatigue, loss of appetite and unexplained weight loss.More severe symptoms may include: shortness of breath, a fast or irregular heartbeat and fever.Other less common or rare non-specific symptoms that may accompany colitis include: arthritis, mouth ulcers, painful, red and swollen skin and irritated, bloodshot eyes.Signs seen on colonoscopy include: colonic mucosal erythema (redness of the colons inner surface), ulcerations and hemorrhage. Diagnosis
Symptoms suggestive of colitis are worked-up by obtaining the medical history, a physical examination and laboratory tests (CBC, electrolytes, stool culture and sensitivity, stool ova and parasites et cetera). Additional tests may include medical imaging (e.g.
