Ehlers-Danlos (EDS) is a set of heritable heterogenous connective tissue disorders characterized by defects in collagen synthesis, affecting skin, ligaments, joints, blood vessels and other organ. EDS patients often have vascular fragility syndromes with arterial aneurysms and dissections. Patients also have kyphoscoliosis and due to the connective tissue abnormalities, these patients often present for orthopedic surgery.  Overall, there is very little evidence-based knowledge for the management of EDS. Much of the literature is based upon expert opinion.

Ehlers-Danlos (EDS) is a set of heritable heterogenous connective tissue disorders characterized by defects in collagen synthesis, affecting skin, ligaments, joints, blood vessels and other organs. EDS patients often have vascular fragility syndromes with arterial aneurysms and dissections. Patients also have kyphoscoliosis and due to the underlying connective tissue abnormalities, these patients often present for orthopedic surgery. Overall, there is very little evidence-based knowledge for the management of EDS. Much of the literature is based upon expert opinion.

Anesthetic implications

Preoperative optimization

  • Preoperative evaluation should focus on bleeding history, cervical/TMJ hypermobility, skin fragility, scoliosis, signs of mitral/aortic insufficiency
  • Vascular instability may cause major vessel dilation and cause aortic or mitral insufficiency

Intraoperative management

Monitoring:
  • Arterial lines run the risk of vascular wall dissection. Consider ultrasound-guided arterial line placements
  • EDS patients can often demonstrate orthostatic tachycardia syndrome (POTS)
Positioning:
  • Eyes should be protected to prevent retinal detachment and globe rupture
  • Careful padding of extremities
Skin Fragility
  • Minor forces can result in skin injuries such as tape, stickers, and other monitors that attach to the patient
  • Bruising and hematoma formation occurs with repetitive non-invasive BP monitoring
  • Special attention to removing tape from eyes and skin
  • Discuss the risk/benefits of using a tourniquet in these patients with surgical team
Airway Management:
  • Care should be taken for TMJ joint laxity during laryngoscopy
  • EDS patients may present with occipitalatlantoaxial instability causing TMJ joint dislocation

Postoperative management

  • Early mobilization is helpful to prevent muscle loss
  • Inspect surgical sites for hematomas or bleeding
  • Patients with POTS should be monitored early after surgery for bleeding and cardiovascular instability
  • Treat PONV aggressively to avoid esophageal rupture from violent vomiting
  • EDS patients can have pneumothorax after positive pressure ventilation
  • EDS patients with epidurals have greater risk for PDPH and epidural hematoma formation

Related surgical procedures

Pathophysiology

Mutations to genes that code for fibrillar collagen proteins in connective tissue

Their are six manor subtypes ranging phenotypically from very mild to life-threatening phenotypes.[1][2]

Signs and symptoms

  • Joint hypermobility/instability
  • kyphoscoliosis
  • Skin fragility
  • Aortic root dilitation causing aortic insufficiency

Diagnosis

Treatment

No treatments currently exist

Medication

Incidence is low and hence lacks randomized drug trials

Drug therapy will be protected under Orphan Drug development policies

Surgery

Prognosis

Epidemiology
