Impact of the number of veins repaired in short-term digital replantation survival rate.

BACKGROUND: Venous congestion/insufficiency plays a major role in failure of finger replantation. Despite acceptable salvage rates with postoperative anticoagulation or leeching, operative technique remains the most important predictor of success. However, there are no indications in the literature on the benefit of anastomosing single versus multiple veins. METHODS: A retrospective review of finger amputations from 2011 to 2013 was conducted. The analyzed endpoint was the finger survival rate at discharge depending on the number of veins repaired: multiple veins (group 1), only one vein (group 2), or no veins (group 3). Proportions were compared using v2 tests/Fisher's exact tests; p-value <0.05 was considered significant. RESULTS: Seventy-two patients with complete digital amputation were operated including 101 fingers. Twenty-seven fingers (26.7%) failed before hospital discharge, with 78% of failures due to venous complications versus 22% with an arterial etiology. Group 2 had 15 replantation failures due to venous causes as opposed to only one from group 1, representing a 1.27-fold (95% confidence interval (CI): 0.99, 1.34) increased relative risk of failure (p = 0.032). Similarly, five fingers from group 3 suffered venous complications, resulting in a 1.49-fold (95% CI: 1.02, 1.73) increased likelihood of failure in comparison to group 1 (p = 0.008). No significant difference was observed between having only one vein repaired versus none (RR: 1.1792, 95% CI: 0.83, 2.10, p = 0.502). CONCLUSION: Efforts toward favoring two-vein repair lead to better survival of the replanted fingers. More cases need to be analyzed before formulating conclusions on specific levels of amputation with regard to venous anastomoses.

Beyond the borders of keloid formation: A case report.

The keloid scar is a cutaneous mass characterized by nodular fibroblastic proliferation of dermis and a predilection for distinctive anatomical locations. However, keloid extension to neighbouring tissue as a nonsyndromic entity has not been described. In the present report, a case involving a 48-year-old woman with extensive bilateral keloids of the ear lobules and neck following ear piercing is presented.

A rare presentation of flexor digitorum profundus type V avulsion injury with associated intra-articular fracture: A case report.

Traumatic avulsions of the flexor digitorum profundus tendon are associated with young adults engaged in athletic activities such as football and rugby. The current report presents a case involving a 30-year-old man with traumatic avulsion of his flexor digitorum profundus and associated intra-articular distal phalangeal fracture secondary to injury during martial arts - an unusual cause of this injury. Increased attention to injuries acquired during this form of sporting activity is suggested.

Mechanical failure of a Fogarty catheter in a microsurgical procedure: a case report.

Although microvascular free-tissue transfer has become a reliable reconstructive method, vascular compromise of the flap necessitating surgical exploration and attempts at flap salvage commonly occurs. Thrombectomy using Fogarty vascular catheters can be used in the setting of vascular pedicle thrombosis. However, this is not without potential complications. The following report describes a case in which the use of a Fogarty vascular catheter during a thrombectomy for microsurgical flap salvage resulted in complete separation of the balloon from the catheter.
