Randomized, double-blind clinical trial comparing the healing of stasis ulcers in lower limbs with standard hydrocolloid gel dressings and with dressings with Syzygium cumini extract.

OBJECTIVE: To evaluate the healing of venous ulcers in the lower limbs (VLU) using dressings with hydrocolloid gel associated with Syzygium cumini extract (SHG) compared to standard hydrocolloid gel dressings (HG). METHOD: This prospective, double-blind, randomized trial recruited 90 patients with VLU divided into: dressings with SHG (n = 44) and dressings with HG (n = 46). Primary endpoint was healing in the 14th visit. Secondary endpoints were healing rate, complete healing during follow-up, and improvement in the pain scale and in quality of life. RESULTS: There were no significant between-group differences in healing (p = 0.15). The wound area made healing difficult (p = 0.008). Age, body mass index, and wound time demonstrated a tendency to worsen the healing. Positive culture for Pseudomonas aeruginosa resulted in 88% reduction in the healing risk (p < 0.0001). CONCLUSION: There was no difference between the dressings evaluated. The presence of Pseudomonas aeruginosa significantly impaired wound healing.

Fístula arteriovenosa após escleroterapia com espuma guiada por ultrassom: relato de caso / Arteriovenous fistula after ultrasound guided foam sclerotherapy: case report

A escleroterapia com espuma guiada por ultrassom tem ganhado espaço no tratamento da insuficiência venosa crônica secundária a varizes dos membros inferiores. Trata-se de procedimento ambulatorial, de baixo custo e sem necessidade de afastamento das atividades habituais. Apresenta bons resultados clínicos, especialmente nos estágios mais avançados da doença. Quando bem aplicada, apresenta baixas taxas de complicações maiores. Porém, a técnica apresenta altas taxas de recanalização no médio e longo prazo, e seu mecanismo ainda não é totalmente compreendido. O presente artigo descreve um caso de fístula arteriovenosa em segmento de recanalização de veia safena magna, após escleroterapia com espuma guiada por ultrassom, e identificada por exame ultrassonográfico de vigilância pós-procedimento.

Ultrasound-guided foam sclerotherapy has become widespread in the treatment of chronic venous insufficiency secondary to varicose veins. It is a low-cost, outpatient procedure that does not require medical leave. It has demonstrated good clinical results, especially in the more advanced stages of the disease. When employed correctly, it results in low rates of major complications. However, the technique exhibits high recanalization rates over mid and long-term follow up. Additionally, the recanalization mechanism has not yet been explained. This article describes an arteriovenous fistula in a recanalized segment of great saphenous vein previously treated with ultrasound-guided foam sclerotherapy that was detected during post-procedure follow-up with ultrasound.
