More than 50% of all congenital haemangiomas are located on the head and neck. Because most orofacial haemangiomas exhibit the tendency to grow rapidly, they are often treated by embolisation and excision. CASE REPORT. The case of a 5-year-old patient is presented, who was admitted to the hospital for embolisation and immediate surgery of a haemangioma of the right side of the face and upper lip. After the injection of 2 ml fibrin glue she suddenly developed hypotension, tachycardia, a low oxygen saturation, and a low end-tidal carbon dioxide partial pressure. There was no failure of the breathing circuit and no airway obstruction could be found. Most likely these symptoms were due to transport of the fibrin glue from the haemangioma into pulmonary vessels. The therapy included the administration of heparin and antihypotensive drugs. After stabilisation, the patient was transferred to the intensive care unit for 1 day without further complications. CONCLUSION. Pulmonary embolism after injection of fibrin glue into an orofacial haemangioma has not previously been reported, but it should be considered that systemic complications can occur after injecting substances for embolisation into vessel-rich tissues.

We describe a 35-year-old man who had a pulmonary embolism with thrombosis of the inferior vena cava, apparently resulting from compression by a hepatic hemangioma. The diagnosis of pulmonary embolism was confirmed by pulmonary angiography; however, the hemangioma was detected only incidentally, as a hyperechoic mass, during an echocardiogram for intracardiac thrombosis. Abdominal sonography, computed tomography, celiac angiography, technetium 99m-labeled red blood cell scintigraphy, and ultrasound-guided liver biopsy all assisted in the diagnosis of hepatic hemangioma and its compression of the inferior vena cava. Because of the multisegmental and perihilar involvement of the tumor, surgery was not performed. For dissolution of the clots, the patient was given thrombolytic therapy followed by heparin administration. He was then placed on long-term warfarin therapy and is well after 5 years; the size of the hemangioma is unchanged. Cases of pulmonary embolism due to diseases of the upper abdominal organs are rare and probably underestimated. This case stresses the need for a systematic investigation of the abdomen when a pulmonary embolism is present without evidence of deep vein thrombosis.

A 75-year-old man with a recent history of pulmonary embolism, presented with collapse followed by a gran mal seizure and right-sided non-pulsatile proptosis. On recovery, he had diplopia on lateral and upward gaze and signs of congestive cardiac failure. Further pulmonary embolism was proven by lung scintigraphy. Computed tomography of his orbits confirmed a contrast-enhancing space-occupying lesion of the medial wall of the right orbit, with no intracranial abnormality. The patient was investigated for metastatic tumour as a possible cause of the space-occupying lesion and the unprovoked thromboembolic event, but no evidence of malignancy was found. The orbital lesion was not biopsied because of the risk of bleeding from anticoagulation. Three weeks later, the patient represented with recurrent cardiac failure, proptosis, and diplopia. A transorbital ultrasound confirmed an encapsulated, well-defined vascular lesion, with typical appearances and Doppler flow characteristics of a cavernous haemangioma. Diuretic therapy abolished the proptosis and diplopia in tandem with relief of the cardiac failure. This is the first description of recurrent proptosis with diplopia due to recurrent congestive expansion of an orbital cavernous haemangioma.

We report a case of pulmonary embolism associated with percutaneous sclerotherapy (absolute ethanol: 0.5 mL.kg-1) of a venous angioma, performed under general anaesthesia in a 13 year-old child. The diagnosis of pulmonary embolism, suspected on the clinical setting and symptoms, was supported by the pulmonary scintigraphy obtained 4 hours later, showing 3 minimal pulmonary defects. The outcome was rapidly favourable without sequelae under heparin administration and the pulmonary scintigraphy, performed on day 7, was normal. The role of absolute ethanol, for explaining the apparent contrast between the severity of the symptoms and the minimal obstruction noted on pulmonary scintigraphy is discussed. Also discussed are the prophylactic and curative therapeutic issues of this severe complication.

A 48-years old man complained of dyspnea and was admitted to the hospital. Chest enhanced CT confirmed the presence of the thrombus in the pulmonary artery. Cardiac catheterization showed severe pulmonary hypertension (mean PAP 75 mmHg). ATIII level, protein C and S antigen were within normal range. Anticardiolipin antibody and lupus anti-coagulant determination were negative. He was diagnosed as chronic pulmonary thromboembolism, and underwent pulmonary thromboendarterectomy via median sternotomy under deep hypothermic intermittent circulatory arrest. At the same time IVC filter was inserted. The origin of the thrombus was not detected before operation, but after surgery, MR angiography of total body showed a cavernous hemangioma at left lower limb. We speculated this lesion was the origin of pulmonary embolism.

Numerous findings incidental to the stated indication for obtaining a computed tomogram (CT) of the chest are encountered. While some findings are life threatening (eg, pulmonary embolism), others are clearly benign (pulmonary hamartoma, vertebral hemangioma). This article discusses management issues related to the detection of unexpected findings in different compartments of the thorax. In the future, more detailed outcome data will be available to better guide medical decision-making.

A vertebral fracture, whether originating from osteoporosis or trauma, can be the cause of pain, disability, deformation and neurological deficit. The treatment of vertebral compression fractures has, for many years until the advent of vertebroplasty, consisted of bedrest and analgesics. Vertebroplasty is a percutaneous technique during which bone cement is injected in a vertebral body to provide immediate pain relief by stabilization. Inflatable bone tamps can, prior to the injection of cement, be used to create a void in the vertebral body, in which case the technique is known as balloon vertebroplasty (or kyphoplasty). The chance of extracorporal cement leakage is smaller for balloon vertebroplasty than for vertebroplasty. Some authors also claim to have gained some correction in vertebral body height or angulation. Both interventions can be used for several indications, including osteoporotic compression fractures and osteolytic lesions of the vertebral body such as myeloma, hemangioma or metastasis, and also for traumatic burst fractures in combination with pedicle screw instrumentation. Polymethyl methacrylate cement is the bone void filler that is used most frequently, although the application of calcium phosphate cements has been studied widely in vitro, in vivo and also in small-scale clinical series. The clinical results of (balloon-) vertebroplasty are favorable with 85-95% of all patients experiencing immediate and long-lasting relief of pain. Serious complications are relatively rare but include neurological deficit and pulmonary embolism. In this paper, both vertebroplasty and balloon vertebroplasty and their respective indications, techniques and results are described in relation with the application and limitations of permanent and resorbable injectable bone cements.

Very large full thickness defects of the thorax or abdomen after tumoral resections commonly need to be reconstructed with free tissue transfers. We retrospectively analysed the protocol of performing the free tissue transfer before the wide excision in 15 patients (mean age of 48) with large tumours of the thorax and abdomen. During the first stage, the flap was folded on itself in a strategic position close to the future resection site and microsurgical anastomoses performed. The second stage surgery consisted of the full thickness excision and definitive reconstruction of the defect by unfolding the flap over prosthetic material. The inclusion criteria were: large thoracoabdominal resections exposing lung or bowel and requiring the use of prosthetic material as part of the reconstruction after resection for locally aggressive tumours such as dermatofibrosarcoma protuberans. In 8/10 patients, vein grafts were used in the arterial anastomosis. The mean time interval between the first and the second stage was 17 days (7-50 days). Flap survival was one hundred percent on first attempt. In one patient who had presented with a large abdominal haemangioma, pulmonary embolism occurred during the second stage. In another patient, an infection under the flap occurred 3 years after reconstruction. Results of this series of patients support our belief that a two-stage microsurgical strategy can be useful in selected patients where large free flaps (with grafted pedicle) in combination with prosthetic materials have to be performed for reconstruction of full thickness defects of the trunk or the abdomen.

In our cohort of 555 patients with a total of 1150 vertebral fractures treated with kyphoplasty we performed a 30-day postoperative analysis of cement leakage, neurological symptoms, pulmonary embolism, and infections. In our department, 22% of kyphoplasties were performed with calcium phosphate cement and the remainder with polymethylmethacrylate. All patients were initially assessed by an interdisciplinary kyphoplasty colloquium, composed of consultants in traumatology, radiology, and endocrinology. Indications included fresh traumatic vertebral fractures; painful sintered osteoporotic vertebrae; osteolysis and painful vertebral body collapse caused by multiple myelomas; and lymphomas and pathological fractures due to metastases of malignant tumors (prostate cancer, breast cancer, ovarian cancer, and malignant melanoma) or benign vertebral tumors (hemangioma). Contraindications included patients with instability of the posterior wall and/or pedicles, an infection of the fractured vertebra, a severe hemorrhagic diathesis, known allergies to the cements, pregnancy, and ASA score of 4. The standard postoperative computed tomography scan of the kyphoplasty-treated vertebrae revealed a dorsal cement leakage in 38 vertebrae representing 3.3% of all levels. A permanent monoparesis of the left leg, 2 cases of temporary neurological deficits, 2 cases of hemorrhage, and 1 asymptomatic pulmonary embolism were observed as postoperative complications. We observed no complications relating to polymethylmethacrylate described in the literature. By careful interdisciplinary indication setting and a standardized treatment model, kyphoplasty presents a safe and effective procedure for the treatment of various vertebral fractures.

A 39-year-old woman was diagnosed in infancy as suffering from Klippel-Trenaunay-Weber syndrome, affecting both her lower limbs. She had undergone, for several times, gastroepiploic transplantation at 18 years of age. She was scheduled for lymphaticovenular anastomosis of the right limb. Preoperatively, computed tomography showed no thrombosis in her lower limbs. We gave only general anesthesia, because of her strong anxiety, and concern of hemangioma and blood vessel malformation in epidural space. General anesthesia was induced with thiopental, fentanyl, and vecuronium, and maintained with nitrous oxide, oxygen and sevoflurane. Tourniquet had been used for only 30 minutes considering the risk of occurring deep vein thrombosis. Surgery was successfully finished in eight hours and thirty minutes. Using tourniquet increases the risk of deep vein thrombosis and pulmonary embolism. We should use tourniquet as briefly as possible to avoid the occurrence of pulmonary embolism. We recommend avoidance of epidural analgesia, as the patient may have hemangioma and arteriovenous malformation in epidural space, and we should evaluate them by magnetic resonance imaging before anesthesia.
