CoRDTS et al. (1998) described ovarian vein embolization in nine women with symptoms of pelvic congestion syndrome using coils and absorbable gelatin sponge [37]. Embolization of both ovarian veins was performed in four women, of the left ovarian vein alone in four patients, and of a left obturator vein that communicated with vulvar varices in one patient. The authors reported that eight of the nine women (88.9%) had more than 80% immediate relief but that two women had a mild to moderate return of the symptoms at 6 and 22 months. Improvement in symptom relief varied from 40% to 100% at a mean time of 13.4 months. 

In bone lesions that are assumed to be extremely hy-pervascularized such as suspected metastases of renal cell carcinoma, a digital subtraction angiography may have to be obtained prior to biopsy. Transarterial embo-hzation or direct puncture of the lesion with injection of absorbable gelatin sponge or polyvinyl alcohol particles helps to prevent serious hemorrhage when samples of the lesion are taken.

Absorbable particles consist mainly is Gelfoam (gelatine sponge) powder (40-60 pm) or particles (any size), the use of autologous clot or Avitene has also been described. The occlusion achieved with this material is not permanent and vascularization is reconstituted in 7 to 21 days after the procedure. The Gelfoam can be easily cut, and placed in contrast material to be injected through small lumen catheters. 

Another interesting approach is Gelfoam , which is made of absorbable gelatin sponge USP. It can be inserted in the conjimctival pouch in the form of small disks (e.g 4 mm in diameter and 0.5 mm thick) impregnated with drag solutions. They have been shown to improve the managanent of pupillary dilation in humans as well as the delivery of pilocarpine [104-106].

Gelatin is produced by partial acid or partial alkaline hydrolysis of animal collagen. It has a wide variety of therapeutic and pharmaceutical uses. It is often used in the manufacture of hard and soft capsule shells, suppositories and tablets, and is sometimes used as a sponge during surgical procedures, as it can absorb many times its own weight of blood.
