“…A variety of solutions for poor venous outflow exist, including vein grafting, leeching, arteriovenous fistulas, pinprick incisions, venous pumping devices, and open vessel drainage (Kim, Jeong, Choi, & Kim, ; Lendvay, Teston, Mayer, & Lyons, ). Intraoperative discussion was held to consider the use of a vein graft.…”

“…Vein grafting would have been from the nasal dorsum to either the superficial temporal vein or to the facial vein and because of the significant length needed as well as the very small caliber of the avulsed vessel, it was decided not to attempt a vein graft. Medicinal leeches were used in this case because they were readily available, manageable, and their utility in microvascular surgery was well documented (Flores et al, ; Jose, Varghese, & Babu, ; Kim et al, ; Lendvay et al, ; Nguyen, Crosby, Skoracki, & Hanasono, ; Stillaert et al, ).…”

Microvascular replantation of a composite facial avulsion in a 24‐month‐old child after dog bite

Dog bite injuries are common sources of morbidity with an estimated incidence of 4.5 million bites per year with over 350,000 requiring treatment in the emergency room. Children under the age of 14 are most likely to be affected with a peak age of 5-9 years old. We report a case of a 24-month-old female who sustained a large composite facial avulsion injury from a pit bull dog bite. The avulsed tissue involved a substantial portion of the patient's mid-face, including the entire soft tissue of the nose, upper lip, part of the left cheek, and left oral commissure. Artery-only microvascular replantation was performed because no recipient vein could be identified from the facial defect. Medicinal leech therapy was used for eight days postoperatively to prevent venous congestion. The patient experienced significant blood loss due to leech therapy and required nearly 29 L of blood product replacement. At the last follow up of 8 months postoperatively, the patient was recovering well with significant improvement in function and cosmesis of the mid-face. This case describes a successful artery-only replantation of an avulsive bite injury to the face of a young child. Despite the technical difficulty of cases such as this one, microvascular replantation should be attempted because when successful it provides a superior cosmetic and functional result to other reconstructive techniques.

Replantation of amputated rat feet utilizing an efferent arteriovenous shunt constructed between the distal posterior tibial artery and the proximal posterior tibial vein, in the absence of all other venous drainage, provides an alternative pathway to the normal venous drainage in a replanted rat foot. However, this substitute venous drainage was insufficient to prevent progressive ischemia and necrosis of some or all of a replanted rat foot. When a cutaneous pedicle flap supplemented the arteriovenous shunt, venous drainage was much improved, tissue hypoxia and edema began to subside on the third day, severe tissue necrosis was prevented, and seven of eight feet replanted by this technique survived. These observations may be useful in replantation in humans when veins in the amputated part are too small to be used or so damaged that they cannot be repaired or reconstructed by a vein graft, but arteries can still provide a means of returning blood from the amputated part. Constructing an alternative pathway to the normal venous drainage pattern may allow severely damaged parts to survive after replantation.

Replantation of an amputated nasal tip with open venous drainage

Replantation of small parts often results in failure. The impractical size and the frequent absence of veins suitable for anastomosis, together with venous congestion and thrombosis, are the main problems. A case is described of an amputated nasal tip and successful replantation by means of microsurgical arterial repair and open venous drainage due to absence of suitable veins in the specimen. In cases in which there is no possibility of repairing the venous system, open venous drainage may be an easy and feasible method to prevent venous congestion and replant failure.
