TenaTac® was used for bleeding control in a difficult hepatectomy case after haemostasis could not be achieved by Surgicel® Fibrillar™, EviCel® or Argon-beamer.
Case studies
Application of TenaTac® in liver surgery
Procedure: Hemi-Hepatectomy
1.
2.
Two TenaTac® were put on the bleeding surface and compressed for three minutes with moist gauze.
3.
Excellent adhesion and haemostasis was observed. Note the flexible nature of the TenaTac® as it curves around the cut edge of the liver.
Application of TenaTac® in gallbladder surgery
Procedure: Laparoscopic cholecystectomy
1.
TenaTac® was cut into three strips lengthwise.*
*Note: TenaTac® can also be lightly compressed and rolled by hand prior to trocar insertion (with the columns on the outside for optimal placement)
2.
TenaTac® was introduced through a 10mm trocar, unfolded and applied to the bleeding site.
3.
TenaTac® adhered to the wound and stopped the bleeding, forming a gel-like clot.
Application of TenaTac® in neurosurgery
Procedure: Retrosigmoidal craniotomy / Microvascular decompression
1.
The surface modification of TenaTac® makes it flexible enough to match contours. Here TenaTac® was placed on top of, and adhered to, another haemostat which had been used on the dura mater.
2.
The bone flap was placed on top of TenaTac®, which then adhered to the bone and closed off the open spaces around the bone flap. Additional pieces of TenaTac® were used to fill in other gaps around the bone flap.
Application of TenaTac® in thoracic surgery
Procedure: Lung resection
1.
TenaTac® is initially applied DRY along the staple line or on the source of the air leak and then compressed into place with moistened gauze tampons.
Note: Any water immersion testing should be completed before using TenaTac. The lung should be partially inflated prior to applying TenaTac.
2.
The tampons are then moistened again with saline and gently pressed on the product to moisten it further.
3.
This causes TenaTac® to transition from a white patch to a gel-like layer that covers the staple line and is adhesive and highly elastic.
Application of TenaTac® in gastrointestinal surgery
Procedure: Tumor resection (minimally invasive)
1.
TenaTac® is compressed and rolled through a 12mm trocar. It is then unrolled and placed on the wound site (column-side down).
2.
A moist gauze is used to compress TenaTac® for 1-3 minutes (depending on experience).
3.
The gauze is carefully removed and TenaTac® has transformed into an elastic, semi-transparent hydrogel.
Application of TenaTac® in spinal surgery
Procedure: Lumbar arthrodesis
1.
Three TenaTac® are cut to a small size and placed on the wound site.
2.
Moist neuropatties are used to cover TenaTac® .
3.
In another procedure, TenaTac® is shown being applied directly to the dura mater.
Application of TenaTac® in thyroid surgery
Procedure: Thyroidectomy
1.
TenaTac® is cut to size as required and applied dry.
2.
A moist gauze swab has been used to gently press TenaTac® onto the wound site for 1-3 minutes (depending on experience).
3.
TenaTac® adheres to the tissue, provides hemostasis and protects the recurrent laryngeal nerve (RLN).
