Ultrasound-guided mini-incision technique for CHIVA / Técnica de mini-incisões guiadas por eco-Doppler para realizar CHIVA

Abstract CHIVA (Cure Conservatrice et Hemodynamique de l'Insuffisance Veineuse en Ambulatoire) is a surgical technique for varicose veins that avoids destroying the saphenous vein and collaterals. In some patients, the flush ligation of saphenous collaterals performed in the CHIVA technique may require more dissection than is desirable. This is especially valid for obese patients and thigh ligations. We report an innovative technique that uses duplex-guided puncture to bring the collateral closer to the skin and reduce the need for dissection and incision. The technique does not change any of the CHIVA principles. While the long-term results are not yet known, we expect them to be similar to normal CHIVA procedures.

Resumo CHIVA (Cure Conservatrice et Hemodynamique de l'Insuffisance Veineuse en Ambulatoire) é uma técnica de cirurgia de varizes que evita a destruição da safena e das colaterais. A ligadura rasante de colaterais da safena usando a técnica CHIVA pode requerer mais dissecção do que o desejado em alguns subgrupos de pacientes, principalmente os obesos. Este estudo descreve uma técnica inovadora de ligadura das colaterais com mini-incisões guiadas por eco-Doppler. A técnica consiste em puncionar com eco e passar um fio ao redor da colateral para puxá-la para cima. Uma pequena incisão é feita exatamente onde a colateral está situada sob a pele. A veia é tracionada e ligada em sua junção com a safena. A técnica é factível e pode diminuir a incisão e o trauma cirúrgico. Os resultados a longo prazo são desconhecidos, mas esperamos que sejam semelhantes aos da técnica CHIVA, já que nenhum dos preceitos é modificado.

A Case of Eruptive Vellus Hair Cyst Treated by Mini-incision / 대한피부과학회지

Eruptive vellus hair cysts are yellowish or reddish-brown and are grouped or scattered papules with a smooth or crusted surface. The cysts occur predominantly over the anterior part of the chest, extremities and axillae, although they can also be seen on the neck and groin and may range from a single lesion to hundreds. Lesions have rarely been reported to regress spontaneously, so patients request treatment for cosmetic reasons. Few case reports exist on therapy for eruptive vellus hair cysts. It is known that therapies can lead to unsatisfying results or recurrences. We report a case of an eruptive vellus hair cyst successfully treated by mini-incision.
