Klippel Trenaunay Syndrome

Klippel-Trénaunay syndrome (KTS) is a rare vascular congenital anomaly affecting less than 200,000 people in the United States. Vascular malformations associated with KTS tend to affect slow flow systems: venous, capillary, and lymphatic systems. The nature of the syndrome leads to a higher risk for the development of arteriovenous malformations. Our case presentation describes a patient with KTS and an associated rare presentation of intraventricular arteriovenous malformation (AVM).

Hemodynamic Measurements

Abstract The presence of an intracranial arteriovenous malformation has a dramatic impact on local circulatory dynamics. Treatment of some arteriovenous malformations can result in disastrous hyperemic states caused by redistribution of previously shunted blood. This report describes serial hemodynamic measurements of both cerebral blood flow and flow velocity in 3 patients during treatment for arteriovenous malformations. Measurements of cerebral blood flow were made by computed tomographic scan employing the stable xenon inhalation technique; flow velocity, including autoregulatory characteristics, was measured by transcranial Doppler ultrasonogram. Substantial hyperemia developed in one patient (Case 1) after resection and in another (Case 3) after embolization. Embolization resulted in restoration of normal regional cerebral blood flow in a patient who demonstrated hypoperfusion before treatment (Case 2). In Patient 1, postoperative hyperemia was associated with persistently elevated flow velocities, and may have been accompanied by hemispheric neurological deficits. Sequential hemodynamic measurements may predict patients at risk of perioperative complications, and may become useful clinical guidelines for the extent and timing of embolization and for the timing of surgery after intracranial hemorrhage or preoperative embolization procedures.

Vascular anomalies are a heterogeneous group of congenital blood vessel disorders more typically referred to as birthmarks. Subcategorized into vascular tumors and malformations, each anomaly is characterized by specific morphology, pathophysiology, clinical behavior, and management approach. Hemangiomas are the most common vascular tumors. Lymphatic, capillary, venous, and arteriovenous malformations make up the majority of vascular malformations. Arteriovenous malformation of the head and neck is a rare vascular anomaly but when present is persistent and progressive in nature and can represent a lethal benign disease. Here we present a case report of a 25-year-old male patient with arteriovenous malformation involving the base of tongue.

Clinical And Pathological Features

Abstract A peculiar nonneoplastic oligodendroglial proliferative abnormality associated with cerebral arteriovenous malformations (AVMs) was present in three patients. Histological examination of biopsy material revealed dense oligodendroglial tissue reminiscent of oligodendroglioma in the white matter adjoining the AVMs. Careful consideration of clinical and pathological features suggested that the evidence was insufficient to qualify the lesion as truly neoplastic (oligodendroglioma); rather, a tissue collapse or a hamartomatous proliferation could be considered to be its cause. The literature contains 14 instances of various vascular malformations associated with primary brain tumors, 5 of which were diagnosed as oligodendrogliomas. It is possible, however, that some of the cases reported in the literature constitute oligodendroglial abnormality similar to that observed in our cases rather than genuine oligodendrogliomas. Attention is drawn to this interesting and prognostically important phenomenon.

Abstract Serious morbidity and hyperemic states continue to complicate the treatment of certain intracranial arteriovenous malformations (AVMs). Clinical and radiographic characteristics of 62 patients treated over 3 years were analyzed to determine if hyperemic complications (HCs) (defined as unusual perioperative edema or hemorrhage) and outcome could be predicted. Twenty-five (40%) of the patients were less than 30 years old, 28 (45%) were between 30 and 50, and 9 (15%) were more than 50. A history of hemorrhage was found in 48%, and 34% presented with progressive deficits. Thirteen (21%) developed evidence of HCs; 51 (82%) ultimately had a good outcome, 4 (6%) had a poor outcome, and 7 (11%) died. The incidence of HCs was higher in patients whose AVMs recruited perforating vessels (53%) than those without (7%) (P < 0.001). The presence of preoperative angiographic steal carried a 35% risk of HCs whereas its absence carried a 13% risk (P < 0.05). The sum of the diameters of the feeding vessels was also predictive P < 0.05). Outcome was clearly age-related: good outcome was achieved in 92% of the patients less than 30 years old, 86% of those 30 to 50, and 44% of patients older than 50 (P < 0.05). Left hemispheric AVMs showed less morbidity than right (P < 0.05) as did those without perforating vessel recruitment (P < 0.07). HCs had a dramatic impact on outcome with 92% of patients without HCs having good outcome and 46% of those with HCs recovering well (P < 0.001).

Hemodynamic Stresses

✓ Five cases of retrograde thrombosis of former feeding arteries after removal of an arteriovenous malformation (AVM) are reported. The clinical features of these patients were studied and compared to those of 71 patients without this complication. The following characteristics were found to correlate with retrograde thrombosis: 1) advancing age of the patient; 2) large AVM size; and 3) markedly dilated and elongated feeders. It is suggested that the slow flow in the former feeding arteries that was observed immediately after AVM removal and pathological changes in these vessels due to long-standing hemodynamic stresses contributed to the development of retrograde thrombosis. Neurological manifestations related to retrograde thrombosis were noted in three of the five cases. Although infrequent, this complication should be considered as a serious possibility following removal of an AVM.

Arteriovenous malformation is a vascular malformation with fast-flow shunt from the artery to the vein. Extracranial arteriovenous malformation in the head and neck area is rare disease compared to other vascular malformations such as venous malformation or lymphatic malformation. Extracranial arteriovenous malformations especially on face can cause aesthetic problems, therefore surgeons should consider an importance of cosmetic outcome and choose appropriate treatment plan. We report a case of 51-year-old male who presented with enlarged nasal tip diagnosed arteriovenous malformation. This case showed successful outcome after combination therapy consisted of superselective embolization and surgical resection.

Arteriovenous malformations or hemangiomas are rarely reported complications postrhinoplasty. While surgical lasers are gaining increasing use in the treatment of other etiologies of arteriovenous malformation, the potential for unacceptable cosmetic results justifies examination of other, more traditional techniques for repair of these difficult vascular problems. This case presentation details a successful surgical approach to treatment of the postrhinoplasty arteriovenous malformation and outlines the clinical judgments and findings used to rule out use of the laser as a primary surgical modality.

Abstract Background Chronic proctalgia can have a major impact upon quality of life. There are many potential aetiologies however, in some patients no cause can be identified. Case presentation We present a patient post liver transplant with intractable proctalgia, despite multidisciplinary management including opioids, nerve blocks and surgical intervention. An underlying rectal arteriovenous malformation (AVM) was subsequently identified and successfully treated with embolotherapy. The onset of symptoms coincided with the development of inferior mesenteric vein stenosis, likely leading to engorgement of the malformation due to impaired venous outflow. Neovascularisation secondary to the liver transplant procedure may also have contributed to growth of the lesion. Conclusion This is a rare presentation of rectal AVM. These lesions can be treated with minimally invasive embolisation/sclerotherapy and should be considered in cases of unexplained proctalgia.

Spinal Cord Arteriovenous Malformation

Spinal cord intramedullary arteriovenous malformations (AVMs) have classically been considered congenital lesions that are present from birth. The reason for this dogmatic principal is the fact that a vast majority of these lesions present in pediatric and young adult patients. Interestingly, while many authors have demonstrated the development of de novo nidus-type brain AVMs, there have been no reported cases of a de novo intramedullary or perimedullary AVM of the spine. In this paper the authors describe what they believe to be the first reported case of a de novo AVM of the spinal cord in a young patient who underwent serial imaging from birth for evaluation of a syrinx. Potential pathophysiological mechanisms for the development of de novo vascular malformations of the spinal cord are discussed.
