          Abstract

          Venous malformations of the jugular veins are rare findings. Aneurysms and phlebectasias are the lesions most often reported. We report on an adult patient with an abruptly appearing large tumorous mass on the left side of the neck identified as a jugular vein aneurysm. Upon clinical examination with ultrasound, a lateral neck cyst was primarily suspected. Surgery revealed a saccular aneurysm in intimate connection with the internal jugular vein. Histology showed an organized hematoma inside the aneurysmal sac, which had a focally thinned muscular layer. The terminology and the treatment guidelines of venous dilatation lesions are discussed. For phlebectasias, conservative treatment is usually recommended, whereas for saccular aneurysms, surgical resection is the treatment of choice. While an exact classification based on etiology and pathophysiology is not possible, a more uniform taxonomy would clarify the guidelines for different therapeutic modalities for venous dilatation lesions.

          Venous aneurysms: surgical indications and review of the literature.

          During the last 20 years we diagnosed five cases of venous aneurysm of the jugular (n = 4) and basilic (n = 1) veins. The purpose of this report was to determine the natural history and indications for surgery of venous aneurysms. Our five cases were included in an English-language literature review performed through August 1993. In our series two aneurysms (one external jugular vein, one basilic vein) were excised for cosmetic reasons. Three internal jugular vein aneurysms were followed up for up to 4 years without complications with serial color duplex ultrasonography. Of 32 patients with abdominal venous aneurysms (18 portal, seven inferior vena cava, four superior mesenteric, two splenic, one internal iliac), 13 (41%) had major complications including five deaths. Of 31 patients with deep venous aneurysms of the extremity (29 popliteal, two common femoral), 22 (71%) had deep vein thrombosis or pulmonary embolism and in 17 recurrent deep vein thrombosis or pulmonary embolism developed when patients were treated with anticoagulation alone. Prophylactic surgery is cautiously recommended for low-risk patients with venous aneurysms of the abdomen and strongly recommended for most patients with lower extremity deep venous aneurysms. Other venous aneurysms should be excised only if they are symptomatic, enlarging, or disfiguring.

            Prevalence of deep venous anomalies in congenital vascular malformations of venous predominance.

            The overall incidence of congenital vascular malformations in the general population is 1.5%. Approximately two thirds of them are malformations of venous predominance. Abnormalities of the deep venous trunks have been observed in association with large superficial compensatory varices in these type of malformations. Knowledge of the integrity of the deep venous system is important in their management because excision of the enlarged superficial veins may be deleterious if there is aplasia or hypoplasia of the deep venous trunks. The objective was to investigate the prevalence and nature of deep venous anomalies that occur in patients with congenital vascular malformations of venous predominance both in our series and in the series from the medical literature. From the last 35 years of medical literature, we reviewed seven series of congenital vascular malformations that provided pertinent information on the subject of our study. We also reviewed our own series of 392 patients with congenital vascular malformations studied at Children's Hospital of Mexico City (1963-1983; n = 223 children) and at Walter Reed Army and National Naval Medical Centers (1984-1998; n = 169 children). Of 392 patients, 257 (65.5%) had malformations of venous predominance; these were the subject of our analysis. Prevalence of the following deep venous anomalies was recorded: phlebectasia, aplasia or hypoplasia of venous trunks, aneurysms, and avalvulia. Diagnosis was made by one or more of the following methods: Doppler scanning, duplex scanning, plethysmography, computerized tomography, magnetic resonance imaging, and angiography. At least one anomaly of the deep venous system was present in 47% of the congenital vascular malformations of venous predominance reviewed. Phlebectasia was recorded in 36% of the cases, and aplasia or hypoplasia of deep venous trunks was observed in 8% of the cases. Venous aneurysms also were present in 8% of the cases; avalvulia was recorded in 7% of the cases. Anomalies of the deep venous system occur in almost one half of congenital vascular malformations of venous predominance. The most common is the relatively innocuous phlebectasias that occur in over one third of cases. Aplasia/hypoplasia, venous aneurysms, and avalvulia were less frequent, each less than 10%; but failure to detect the latter three anomalies may lead to serious therapeutic errors.

              Presentation and management of venous aneurysms.

              Venous aneurysms have been reported to occur in most major veins. These aneurysms may be misdiagnosed as soft tissue masses or as inguinal or femoral hernias. Venous aneurysms of the deep system have been associated with deep venous thrombosis (DVT) and pulmonary embolism (PE). To more precisely characterize these lesions, we reviewed our experience with the disease. A retrospective analysis of our experience over 22 years was performed. The presentation and management of these lesions were reviewed and compared with the literature. Thirty-nine venous aneurysms were reported in 30 patients. There were 14 men and 16 women. The patients' ages ranged from 3 to 75 years. Thirty aneurysms were located in the lower extremities, four in the upper extremity, and five in the internal jugular vein. Fifty-seven percent of lower extremity aneurysms occurred in the deep system. Patients' symptoms were a mass (75%) associated with pain (67%) and swelling (42%). Thromboembolism occurred in six patients, DVT in three, and PE in three. Eight of nine patients (89%) who had aneurysms of the superficial venous system had their condition misdiagnosed. Diagnosis was made by phlebography (60%), color flow duplex scanning (27%), continuous-wave Doppler scanning (10%), or magnetic resonance imaging (10%). The aneurysm size ranged from 1.7 to 6.0 cm. Management consisted of tangential excision in five (17%), total excision in 23 (77%), and observation in seven (6%). Venous aneurysms are unusual vascular malformations that occur equally between the sexes and are seen at any age. Most patients have a painful mass of the extremity, and diagnosis is achieved by radiologic examination. Superficial venous aneurysms of the inguinal region are often misdiagnosed. Thromboembolism is more common in aneurysms involving the deep venous system. Because of their potential morbidity, management should be surgical in the majority of cases.
