Follow-up

Further Inpatient Care

  • Admit patients with tuberous sclerosis complex (TSC) who have evidence of increased intracranial pressure for medical treatment and surgical intervention.
  • Patients who present with status epilepticus may require admission for medical treatment and observation.

Further Outpatient Care

  • Patients with tuberous sclerosis complex require regular follow-up care. Evaluation must include a detailed review of manifestations, including seizures, flank pain, hematuria, and school and behavioral issues, as well as blood pressure measurement and funduscopic examination.
  • Patients with tuberous sclerosis complex require surveillance testing based on the schedule outlined in Workup. Testing includes MRI or CT scanning of the brain; electroencephalography; echocardiography; electrocardiography; renal ultrasonography, CT scanning, or MRI; pulmonary CT scanning; and pulmonary function testing (PFT).
  • Routinely monitor patients on anticonvulsant medications for adequacy of seizure control.
  • Patients with behavioral or psychiatric disorders require routine outpatient follow-up evaluation.

Inpatient & Outpatient Medications

  • Various anticonvulsant medications, such as carbamazepine, valproic acid, or lamotrigine,25 may be used for seizure control.26 The goal is monotherapy, although many patients require multidrug therapy for adequate seizure control.
  • The first drug of choice for treatment of infantile spasms is vigabatrin, although it is not yet available in the United States. Other drugs used to treat infantile spasms include prednisone and corticotropin.
  • Antihypertensive medications, such as ACE inhibitors, are needed in patients with renal disease and resultant hypertension.
  • Occasionally, infants or young children with cardiac rhabdomyomas develop heart failure. Inotropic support may be required in some of these patients.

Transfer

  • Immediate transfer is indicated if a patient has evidence of increased intracranial pressure or hydrocephalus and a neurosurgeon is not available.
  • Transfer the patient during the initial workup or surveillance testing if consulting specialists or imaging studies, such as CT scan, MRI, or ultrasonography, are not available.

Deterrence/Prevention

  • Tuberous sclerosis complex cannot be prevented because it is inherited in an autosomal dominant pattern or arises from a spontaneous mutation.
  • Genetic counseling is important for patients, parents, and family members who are considering having children. Genetic testing is under investigation, with mutational analysis currently available on a research basis. Prenatal testing may be available in the future.

Complications

  • Increased intracranial pressure and hydrocephalus
  • Mental retardation
  • Seizures
  • Schizophrenia, aggressive behavior, or other behavior disorders
  • Autism or pervasive developmental disorder (PDD)
  • Renal failure or hemorrhagic shock due to bleeding angiomyolipomas
  • Pneumothorax or obstructive lung disease
  • Cardiac arrhythmia or heart failure
  • Death

Prognosis

  • Tuberous sclerosis complex has a wide clinical spectrum, and some patients are affected subclinically with no decrease in life expectancy or quality of life.
  • A decreased life expectancy is noted in some individuals with tuberous sclerosis complex. This is often related to treatable or preventable causes of death, such as pulmonary or renal disease. Appropriate surveillance studies with any necessary early intervention may improve quality of life and life expectancy.

Patient Education

  • Instruct patients, parents, and family members regarding seizure precautions. A medical identification bracelet may be useful.
  • Educate patients and their families regarding the symptoms of increased intracranial pressure and hydrocephalus so that medical attention may be sought quickly.
  • Provide genetic counseling to assist in family planning.
  • An excellent resource for patients and their family members for information and support is the Tuberous Sclerosis Alliance. The contact information is as follows: Tuberous Sclerosis Alliance

Miscellaneous

Medicolegal Pitfalls

  • Failure to recognize signs or symptoms of tuberous sclerosis complex (TSC)
  • Failure to recognize the presence of increased intracranial pressure and to provide appropriate treatment
  • Failure to obtain appropriate screening or surveillance studies
  • Failure to provide genetic counseling to patients, parents, or family members
  • Failure to screen first-degree relatives for tuberous sclerosis complex once an individual is diagnosed with tuberous sclerosis complex
