Klippel Trenaunay Syndrome

Abstract Parkes-Weber syndrome is a congenital vascular disease that comprises capillary, venous, lymphatic, and arteriovenous malformations. Although Parkes-Weber syndrome is a clinically distinct entity with serious complications, it is still frequently misdiagnosed as Klippel-Trenaunay syndrome, which consists of a triad of malformations involving the capillary, venous, and lymphatic vessels, without arteriovenous fistulas. Both syndromes are generally diagnosed with Doppler ultrasound and confirmed by magnetic resonance angiography. The aim of this study is to describe one case of Klippel-Trenaunay syndrome, in a 36-year-old patient, and one case of Parkes-Weber syndrome, in a 21-year-old patient. We review the literature in order to discuss the possible causes and consequences of these diseases related to venous hypertension and angiodysplasia, taking a clearer approach to their differences, and discussing their treatment.

We retrospectively reviewed our treatment results for spinal intramedullary arteriovenous malformations (AVMs). Fifteen consecutive patients were included in this syudy. Five patient underwent particulate embolization. Surgery was performed in ten patients (including two patient who were treated embolization initially). Five patients, at the beginning of our experience, underwent radical excision of the nidus via the posterior myelotomy. Recent five patients underwent interruption of the feeding pedicles on the surface of the spinal cord. Especially when arteriovenous fistulas (AVFs) or aneurysms were demonstrated, accurate obliteration of them were performed. Four patients, including two with residual AVM after the surgery, underwent irradiation therapy. Anatomically, four AVMs disappeared completely and the other 11 patients have a residual lesions after the treatment. Clinically, three patients improved, six remained unchanged, and six worsened. The causes of neurological deterioration after the treatment were technical complication of embolization in one patient and surgical manipulation in five. There was no patient who experienced hemorrhage during the follow-up period ranged from 6 months to 17 years, with a mean of 7.5 years. In conclusion, particulate embolization should be considered as the first choice of treatment if feasible. Surgical treatment is indicated for the dangerous anatomical features such as AVFs or aneurysms.

Spinal Arteriovenous Malformations

Spinal vascular malformations are rare, with dural arteriovenous fistulas (AVFs) accounting for the majority of the pathology. Unlike spinal arteriovenous malformations, which cause abrupt neurological change as a result of hemorrhage, spinal dural AVFs tend to result in a progressive myelopathy through venous congestion and cord edema. If diagnosed and treated early with endovascular embolization or microsurgery, some deficits may be reversible.

Conjunctival Vessels

Aqueous outflow via the conventional outflow pathway is dependent on the pressure gradient between intraocular pressure (IOP) and episcleral venous pressure (EVP). Elevated IOP resulting from increased EVP is a well-known complication of arteriovenous fistulas, which are usually between the carotid artery and the cavernous sinus. Arteriovenous malformations usually occur spontaneously, after a trauma or from iatrogenic causes, and they manifest with findings of chemosis, dilatation of the conjunctival vessels, exophthalmos, and extraocular motility limitation. In this study, we present a case of elevated IOP due to facial arteriovenous malformations following a functional neck dissection surgery that caused intraocular pressure elevation.
