[Possible lung embolism following embolization of a hemangioma with fibrin glue]

Multiple intraosseous hemangiomas-investigation and role of N-butylcyanoacrylate in management

BACKGROUND

Primary intraosseous hemangiomas are rare (0.7% of all osseous neoplasms), benign, slow-growing neoplasms. These lesions are usually solitary. We are reporting a case of multicentric intraosseous hemangiomas. Investigation, treatment options, and role of N-butylcyanoacrylate (NBCA) in management will be discussed.

METHODS AND RESULTS

A 20-year-old man had multicentric intraosseous hemangiomas involving the skull bones, mandible, vertebra, pelvic bone, and tibial tuberosity. N-butylcyanoacrylate was used by direct puncture technique using a transosseous transcutaneous route to control profuse bleeding from the retromolar region.

CONCLUSION

To the best of our knowledge, this is the first reported case with such extensive multicentric intraosseous hemangiomas. N-butylcyanoacrylate by direct puncture technique can be an effective method to devascularize and stabilize low-flow intraosseous vascular tumors.

Management of low-flow vascular malformations of upper aero digestive system—role of N-butyl cyanoacrylate in peroperative devascularization

OBJECTIVES

Low-flow vascular malformations of upper aero digestive system may cause difficulty in swallowing and/or breathing and bleeding from these lesions may even threaten the life of patient due to risk of aspiration. These lesions may require surgical resection with prior devascularization to minimize blood loss during surgery.

METHODS

Peroperative devascularization of vascular malformations was carried in patients of our study group by injecting N-butyl cyanoacrylate (NBCA) into vascular malformations using direct puncture technique. This was followed by surgical resection of lesion in the same sitting.

RESULTS

Successful devascularization of vascular malformations in all patients in our study group was achieved by injection of NBCA into the lesion by direct puncture technique. There was retraction of malformation due to devascularization, good plane of cleavage was found during subsequent surgical resection and blood loss was minimal.

CONCLUSIONS

Low-flow vascular malformations of upper aero digestive system can be treated with surgical resection after peroperative devascularization. Direct puncture of NBCA into lesion under fluoroscopy control is an effective, safe and inexpensive method of devascularization which can be carried out by the surgeon in a single sitting.

Use of the direct puncture technique in management of capillaro-venous malformations: case report

BACKGROUND: Preoperative devascularization of the capillaro-venous malformations located in the aero-digestive tract is important for surgeons, to minimize blood loss during surgical excision of malformations. CASE PRESENTATION: Here we present two cases of capillaro-venous malformation in which we could successfully achieve preoperative devascularization, by directly injecting n-butyl cyano acrylate into the capillaro-venous bed. This technique is relatively easy, safe and cheap, and can be carried out immediately before surgery.

[Pulmonary embolism in sclerotherapy for a venous malformation in a child under general anesthesia]

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.

Contemporary possibilities of treating vasoformative tissue tumours

The authors present a review of up-to-date methods of vasoformative tissue tumours treatment. The necessity to choose the best therapy and the risks of single therapeutical procedures are pointed out.

Extensive facial vascular malformations and haemangiomas: a review of the literature and case reports

We present 6 selected cases of extensive facial vascular anomalies extending to the skull base or actually involving it. These patients are compared with other cases in the literature. The spontaneous course of these vascular lesions is different and so variable treatment modalities are suggested depending on the age of the patient and the type of lesion. In young children, haemangiomas are common and spontaneous involution is characteristic. Conservative treatment in the sense of a wait-and-see approach is thereby favoured if there is no urgent indication such as involvement of essential structures, e.g. blockage of an orifice as demonstrated in one case or complications such as excessive bleeding. Vascular malformations most commonly appear in adults, there is no tendency to spontaneous involution and resection is usually necessary, especially in arteriovenous malformations. Nowadays, preoperative superselective embolization is recommended to minimize intraoperative blood loss. Superselective embolization is the treatment of choice in cases of a-v fistulae. Proximal ligation of the supplying arteries should be avoided because this may make embolization more difficult, and may be responsible for the common occurrence of rapid revascularization.

Treatment of intraosseous high flow arteriovenous malformation of the mandible by temporary segmental ostectomy for extracorporal tumour resection: a case report

We present a case of intraosseous arteriovenous malformation of the mandible with temporary segmental resection, extracorporal removal of the vascular malformation from the osteotomized mandibular bone and intraoperative osteosynthetic replantation of the avascular bony remnant. In a follow-up after 1 year, when removing the titanium miniplates used for osteosynthesis, the mandibular bone was found to have remodelled completely. There is no recurrence of the lesion in a follow-up after 2 years.
