Non-traumatic splenic rupture in a patient with Kasabach-Merritt syndrome

This report presents a case illustrating the complications of Kasabach-Merritt syndrome in a 22-year-old man. The patient presented with acute abdominal pain and profound anaemia; a CT scan revealed intraperitoneal bleeding from spontaneous splenic rupture. The patient underwent initial emergency laparotomy and splenectomy, with a subsequent further laparotomy to control haemorrhage. Blood products requirements were extensive: 28 units red blood cells, 14 units fresh frozen plasma, 10 units platelets, 10 units cryoprecipitate and 2× Novo VII. He was then transferred to a nearby tertiary care unit for further management to control his coagulaopathy and he made a full recovery after 4 weeks.

Treatment of Facial Venous Malformations with Combined Radiofrequency Current and 900 nm Diode Laser

BACKGROUND

Laser treatment of venous malformations is a major challenge because of the large variations in skin pigmentation, anatomic location, and vessel size and depth.

OBJECTIVE

To determine the safety and effectiveness of electro-optical synergy, a new technology that combines the 900 nm diode laser with radiofrequency current for the treatment of facial venous malformation.

METHODS

Fourteen patients with Fitzpatrick skin types II to IV were treated for facial venous malformations with simultaneous radiofrequency energy (60-80 J/cm3) and optical diode laser energy (fluence 80-100 J/cm2) in one to three sessions. All lesions measured less than 100 cm2. Lesion clearance was evaluated by three specialists on the basis of digital photographs taken before the first treatment and 1 and 2 months after the last treatment.

RESULTS

Thirteen patients showed a complete response and one patient a partial response. The results were rated excellent in the 13 patients and good in one patient. Transient swelling, erythema, and pain were present in all patients, with permanent scarring in only one patient.

CONCLUSION

The combination of laser light and radiofrequency energy is effective and safe for the treatment of facial venous malformations. It provides additional heating of the vessels without increasing laser intensity. The side effects are minimal.

Case report: Kasabach-Merritt syndrome: a review of the therapeutic options and a case report of successful treatment with radiotherapy and interferon alpha

We describe the successful treatment of a neonate with Kasabach-Merritt syndrome who received local irradiation and interferon alpha therapy after failure of corticosteroid treatment. A male neonate, born after an uneventful pregnancy, had a huge haemangioma involving the upper right cervical region as well as severe thrombocytopenia. He was treated with corticosteroids, interferon alpha and radiotherapy. Prednisolone therapy (5 mg kg(-1) day(-1)) was started at 41 days of age. No therapeutic effect was observed after 2 weeks. At this time the tumour size had increased dramatically, platelet counts had decreased progressively and coagulation abnormalities had developed. Because corticosteroid therapy had been ineffective and the child was in a life-threatening condition, irradiation was delivered up to a total dose of 9.5 Gy in five fractions. Simultaneously, prednisolone therapy was slowly decreased and interferon alpha therapy (3 million U m(-2) day(-1)) was started and continued for 6 weeks. After irradiation with 9.5 Gy and beginning interferon alpha therapy, the tumour decreased in size and coagulation parameters normalized within 4 weeks. 6 months later, platelet counts and coagulation parameters were still normal. The tumour had further decreased in size. No acute severe side effects were observed. Radiation therapy combined with interferon alpha treatment is an alternative treatment modality when high dose corticoid steroid therapy has been ineffective in patients with Kasabach-Merritt syndrome, despite the risks of growth delay and secondary malignancy. In children showing no response to corticosteroids, radiotherapy and/or interferon alpha should be considered in Kasabach-Merritt syndrome.

Treatment of venous malformations with an intense pulsed light source (IPLS) technology: A retrospective study

BACKGROUND AND OBJECTIVE

The intense pulsed light source (IPLS) technology provides an innovative concept in the treatment of vascular lesions. We investigated the effectiveness of IPLS in the treatment of venous malformations.

STUDY DESIGN/MATERIALS AND METHODS

A retrospective study of 11 patients with venous malformations (VMA) treated with IPLS was initiated. Clinical VMA characteristics recorded were size and location. Data collected included treatment parameters (filters, pulse duration, fluence, and pulse sequencing), % clearance, and side effects (e.g., swelling, blisters, crusting, pain, altered pigmentation, and scarring).

RESULTS

Good and very good (70-100%) clearance was achieved in 8 malformations smaller than 100 cm(2). Especially small lesions needed only 2-3 treatments. Three VMA larger than 100 cm(2) could be cleared well in an average of 18 sessions. The most frequently used parameters were the 590 nm filter in long pulse mode, triple pulses, and fluences at an average of 80.4 J/cm(2). Side effects included prolonged erythema in 23.6, swelling in 17.9%, crusting in 4.7%. Bleeding, hypo-, hyperpigmentation, and scarring were rare (0.9% respectively).

CONCLUSION

IPLS presents an effective method for treating VMA, especially small malformations, with a justifiable rate of side effects when optimal parameters are chosen.

Outcome of radiation therapy for patients with Kasabach-Merritt syndrome

PURPOSE

The efficacy of radiation therapy for Kasabach-Merritt syndrome, which is characterized by a huge hemangioma with consumption coagulopathy, remains controversial. In this study, we retrospectively investigated the treatment outcome of radiation therapy for seven neonates with Kasabach-Merritt syndrome.

METHODS AND MATERIALS

During the past 25 years we have seen seven children with Kasabach-Merritt syndrome who were treated with radiation therapy. Their ages ranged from 1 day to 5 months, with a median age of 1 month. The hemangioma was located in the extremities in four of seven children. Tumor sizes ranged from 70 cm to more than 150 cm in greatest diameter. Initial platelet counts were all less than 40,000/mm3 except for one patient. In principle, the total dose applied to the hemangioma was 8-10 Gy, with a daily dose of 1 Gy five times a week.

RESULTS

Four of seven hemangiomas responded dramatically, with a concomitant rise of the platelet count to radiation therapy. Although the remaining three hemangiomas, all of which were ill circumscribed by widespread overlying shiny, dusky purple skin, became less tense during radiation therapy. Disseminated intravascular coagulopathy was not improved, but they have responded favorably to two or three courses of radiation therapy with an extended radiation field by 1.5 years of age. As a result, all seven patients are now surviving with no evidence of hemangioma or hematological abnormalities. Shortening of the extremity was observed in three patients who received multiple courses of radiation therapy.

CONCLUSIONS

Radiation therapy appears to be one of the effective treatment options for Kasabach-Merritt syndrome despite the risk of growth delay and malignancy.

YAG laser meloplasty and blepharoplasty

Twenty-eight patients have undergone facelift and blepharoplasty in which the YAG laser scalpel was used. The laser is able to produce an incision with excellent hemostasis. The patients in this series demonstrated markedly diminished blood loss during surgery and reduced bruising, swelling, pain, and discomfort postoperatively. Contralateral procedures done with the laser on one side and conventional surgery on the other side demonstrated greater benefit on the laser side.

Hemangioma of penis and scrotum

Hemangiomas of the genitalia are extremely rare. A hemangioma is self-limited and usually resolves spontaneously, therefore conservative treatment is generally recommended. However, genital hemangiomas may require surgical treatment if they become symptomatic. Herein we report a case of hemangioma of the penis and scrotum requiring surgical excision. The natural history and alternative treatments of hemangiomas are described.

Feasibility of skin deepithelialization using the contact neodymium-yttrium-aluminum-garnet laser

In a manner similar to laserbrasion, the carbon dioxide (CO2) laser has a proven role for expediting skin deepithelialization, which is an essential component of many reconstructive procedures. However, the contact Neodymium-Yttrium-Aluminum-Garnet (Nd:YAG) laser has many additional attributes such as tactile feedback and less plume that theoretically offer an advantage over the CO2 laser for this adjunctive maneuver. In rat experimental models and clinical applications, removal of the epidermis necessary for skin deepithelialization may indeed be achieved using a rounded probe for vaporization with the contact Nd:YAG laser. Unfortunately, the length of time necessary for skin deepithelialization with the Nd:YAG laser exceeded even conventional methods, such that this role with the present technology, although possible, is inefficient and impractical.

Kasabach-Merritt syndrome

The Kasabach-Merritt syndrome includes the triad of vascular tumors, thrombocytopenia, and a hemorrhagic diathesis. The vascular tumors are usually benign but the associated coagulopathy may be life threatening. We describe a patient whose clinical course illustrates the potential difficulties in management.
