Hatem Rajhi .MD Department of Radiology and Interventional Radiology- Charles Nicolle Hospital Tunis -Tunisia

2 PURPOSE To illustrate through a series of observations documented therapeutic methods in the interventional treatment of vertebral hemangiomas

3 INTRODUCTION Vertebral Hémangioma (VH)
The most common benign tumor of the spine • Multiple in 25% of cases • Peak incidence: 40-60 years • Slow-growing lesion • benign vascular dysplasia           capillary           Cavernous (most common)          or Venous (Picture taken from website:

4 INTRODUCTION When to treat a spinal hemangioma?   Usually asymptomatic, discovered incidentally.   Only 0.9% to 1.2% of cases become symptomatic:          Aggressive Hemangioma            Local pain, Radiological aggressiveness Neurologic deficit

5 Background: Semiology of vertebral Hemangioma Radiographic findings
Vertical striations and trabeculations “Honeycomb” appearence. CT axial image “Polka dot” appearance of the involved vertebra MRI increased signal on T1- and T2 weighted images (intralesional fat)

6 Signs of aggressiveness on imaging of Vertebral Hemangioma
Spine level between T3 to T10 • Involvement of the entire vertebral body • Extension to the posterior arch • Discontinuous cortical bone  • Lytic appearence • Paraspinal or intra ductal expansion • Low signal intensity on T1-weighted images • Intense enhancement after contrast injection

7 CASE N°1 A 18 years old patient 09/08/2007  Neurological dysfunction due to spinal cord compression. Radiographic findings: aggressive vertebral hemangioma T3 10/08/2007 bilateral T3 laminectomy  Follow-up: worsening paraparesis Immediate revision surgery: epidural hematoma evacuation

54 PERCUTANEOUS VERTEBROPLASTY

55 PERCUTANEOUS VERTEBROPLASTY
Percutaneous injection of acrylic cement in a pathologic vertebral body  Double effet: Pain relief Vertebral stabilization

56 PERCUTANEOUS VERTEBROPLASTY
Patient preparation Systematic radiological assessment: X-ray + CT + MRI Anesthesia consultation before the procedure. Search for contraindications Informed consent obtained from the patient

57 Absolute Contraindications
- Pregnancy; - coagulation disorders; - Contraindications to anesthesia and prolonged  prone position; - Allergy to PMMA; - Systemic or local infections; - Spinal cord compression with neurological deficit

58 Relative Contraindications
- Pedicles fracture Vertebral body collapse with retropulsion of fracture fragment causing spinal canal compromise Severe vertebral body collapse

59 Technique Fluoroscopic C-arm Guidance CT guidance General anesthesia or local analgesia with or without conscious sedation

60 Equipment Bone cement :PMMA Bone Needles 11 G cm (thoracic spine)  cm (lumbar spine) Surgical hammer Combination pliers

61 Cement preparation Methylmethacrylate powder is mixed with methylmethacrylate monomer liquid. Metallic powder is added to PMMA in order to enhance the visibility of the cement. The preparation is mixed until it becomes like toothpaste Cement volume vary between 2 and 10 ml

62 Cement injection Transpedicular approach Unipedicular or Bipedicular

63 Cement injection Postero lateral approach - pedicular lysis
- osteosynthesis

64 Incidents Vascular leakage of cement - the operator should adjust
the needle direction - or stop the injection immediately. Risk of Pulmonary embolism

65 Spinal canal and epidural extravasation of cement
Incidents Spinal canal and epidural extravasation of cement - Low risk < 1 % - Associated with vertebral fracture: Pedicles posterior wall posterior arch

66 Incidents Foraminal leakage of ciment Risk of compression
of the nerve root

67 Paravertebral cement leakage
Incidents Paravertebral cement leakage Intervertebral disc cement leakage Without major complications

68 Vertebroplasty Results
The analgesic effect is immediate and complete  in the vast majority of cases according to various studies. The frequency of complications is highly variable  depending on the series (1% to 13.5%) It's mostly technical incidents  without major consequences

69 Vertebroplasty Results
H Rajhi and al in 2011: 100% improvement at least partially in the short and medium term Complete regression of pain in the medium term up 57.1% of cases

70 CASE N°2 48 year old woman treated by percutaneous vertebroplasty in 2008 for aggressive vertebral hemangioma T12 with improvement of symptoms.

71 Re-consulted in March 2011 for development of inflammatory back pain with sciatica and sphincter dysfunction.

72 a b c d e f MRI sequences a: sagittale T2 weighted image
b,c : sagittale T1 weighted images d,e : sagittale T1 weighted images with contrast injection f: axial T1 weighted image with contrast injection

73 What is the explanation of the recent symptoms. A. Herniated disc B
What is the explanation of the recent symptoms? A. Herniated disc B. Spondylodiscitis C. Vertebral metastasis D. Reactivation of aggressive Angioma T12 E. Osteoporotic fracture

74 What is the explanation of the recent symptoms?
A. Herniated disc B. Spondylodiscitis C. Vertebral metastasis D. Reactivation of aggressive Angioma T12 E. Osteoporotic fracture

75 Which procedure could be proposed as a treatment. A. Surgery B
Which procedure could be proposed as a treatment? A. Surgery B. Arterial embolization C. Surgery with preoperative embolization D. Vertebroplasty E. Sclerotherapy with Ethanol

76 Which procedure could be proposed as a treatment?
A. Surgery B. Arterial embolization C. Surgery with preoperative embolization D. Vertebroplasty E. Sclerotherapy with Ethanol

77 The decision was to achieve  sclerotherapy with
ethanol injection in the anterior epidural component

78 Sclerotherapy with ethanol injection

79 Sclerotherapy with ethanol injection

80 Sclerotherapy with ethanol injection

81 Sclerotherapy with ethanol injection

82 The outcome was favorable with disappearance of sphincter dysfunction and sciatica
and improvement of the low back pain

83 Control MRI in April 2012 (1 year after sclerotherapy)

84 Control MRI in April 2012 (1 year after sclerotherapy)

85 SCLEROTHERAPY WITH ETHANOL
Direct percutaneous injection of Absolute alcohol Induces: Thrombosis, edema and sclerosis of the Hemangioma Shrinkage of the lesion with  radiculomedullary decompression

86 SCLEROTHERAPY WITH ETHANOL
Intraosseous venography can be performed before alcohol injection          Provides information on the route of preferential venous drainage of the hemangioma          Chek for risk of paravertebral and intra ductal leakage        

87 Technique CT guidance Intravenous conscious sedation and analgesia

88 Technique Unipedicular Bipedicular
Transpedicular approach Unipedicular Bipedicular Postero lateral apparoch -Without significantly changing the absolute nature of the alcohol, we have made alcohol radioopaque by mixing it with contrast media

89 Incidents Potential risk of venous runoff
- Avoided by slow injection of Ethanol Pleural complications and intercostal arteries injury - Avoided by transpedicular approach

90 Complications Risk of collapse of the vertebral body
-Decreased by injecting a small volume of alcohol

91 CONCLUSION A number of methods have been used in the treatment of symptomatic and aggressive vertebral hemangioma, but none of them is optimal. The therapeutic approach depends on the clinical context, the topography and the involvement of the lesion. The decision is multidisciplinary

92 CONCLUSION The interventional radiologist plays an important role:        - Knowledge of the limitations and benefits of each Interventional procedure  Changes in products available    perfect control of techniques    Risk Measurement
