Question
Patient M is an active woman, 70 years of age, who lost consciousness and collapsed at home. Her daughter, who was visiting her at the time, did not witness the collapse but found her mother on the floor, awake, confused, and slightly short of breath. The daughter estimated that she called EMS within 5 minutes after the collapse, and EMS responded within 10 minutes. EMS evaluated Patient M, drew blood for a glucose level.
On presentation in the emergency department, Patient M is immediately triaged. Because Patient M is still somewhat confused, her daughter is asked to provide information on the patient's history. The daughter reports that her mother had had an episode of sudden-onset numbness and tingling in the right limb, with slight confusion and slurred speech, 3 days previously. The episode lasted only 5 minutes, and Patient M had not called her primary care physician. Additional information provided by the daughter indicates that Patient M has been treated for hypertension for 10 years but notes that she is often not compliant with her antihypertensive medicine, a diuretic. The patient has never smoked, drinks occasionally, and is of normal weight.
On physical examination, Patient M's blood pressure is 150/95 mm Hg. She has pain in her left arm and a slight headache. There are slight carotid bruits on the right. She is assessed with use of the NIHSS and found to have left hemiparesis and left visual/spatial neglect. The results of laboratory tests, including a complete blood count, prothrombin time, serum electrolyte levels, cardiac biomarkers, and renal function studies, are all within normal limits. CT of the brain indicates a thrombus in a branch of the right internal carotid artery, with approximately 50% occlusion due to atherosclerosis. There is an area of infarction in the right anterior hemisphere. There is no evidence of a subarachnoid hemorrhage.
CASE STUDY REPORT – BIOL 164 General Outline
Student is presented with a medical case study scenario.
Student will then be asked to create a case study report with 6 content area subheadings. Make sure you answer all the questions comprehensively. Use complete sentences.
1. Diagnosis Name
What is the name of the disease/disorder?
2. Explanation
What are the reasons for your diagnosis?|
3. Causes/Risk Factors
What are some of the factors that put this patient at risk for the disease?
What other questions might you have for the patient that would provide you with more data?
4. Clinical Manifestation
Describe the clinical features of the disease that are present in the individual.
5. Diagnostic Procedures
What types of procedures were done on the patient and what were the results?
Are there other diagnostic procedures that you would like to have performed? If so, which ones and why?
6. Treatment
Describe the treatment plan that you would prescribe for this patient.
Explanation / Answer
1. The diagnosis of the patient is ischaemic stroke or transient ischaemic attack
2. Ischaemic stroke or TIA occurs when the blood supply to the area of brain is compromised due to blockage in corresponding artery. The blockage in the artery may be due to a thrombus or embolus.
Here thrombus in right internal carotid artery is seen. Right carotid artery supplies the left half of the body which is the reason for paralysis of the left arm. This leads to making the diagnosis for ischaemic stroke.
3. Risk factors include:
- Old age
- long standing history of hypertension
- irregularity in administration of prescribed hypertensive drugs
4. Clinical features include:
- weakness and numbness on one side of face, upper limbs and lower limbs
- difficulty in swallowing
- slurred speech
- visual impairment
- confusion and disorientation
- headache and dizziness
5. The diagnostic procedures carried out here are CT and blood tests.
Othe diagnostic procedure include :
CT angiography - to check the blood supply to the brain
MRI - to determine more accurate position of the theombus
ECG and cardiac markers - to check the activity of heart as it is a cerebro vascular disease and may involve heart
EEG - to check the brain activity
6. Treatment
- Thrombolysis with recombinant tissue plasminogen activator can be done within three hours of episode
- Mechanical thrombectomy
- platelet antiaggregants
- statins
- rehabilitation therapy: physical therapy
- antihypertensive drugs
- lifestyle modifications like morning walks, avoiding oily junk food, avoiding alcohol
