Abstract
PURPOSE One of the most common causes of a failure after replantation and revascularization surgeries is 'no reflow' from proximal artery that occurs, especially following crush and avulsion injuries. In this study, we aimed to evaluate the effect of dobutamine treatment on salvage of replanted and revascularized digits. METHODS The patients with no reflow phenomenon detected in the salvage operations of replanted/revascularized digits between the years 2017 and 2020 were included in the study. Dobutamine treatment was infused at a rate of 4 µg·kg-1·min-1 intraoperatively and of 2 µg·kg-1 min-1 postoperatively. Demographic data (age, sex), digit survival rate, ischemia time, and level of injury were retrospectively analysed. Pre-infusion, intraoperative and postoperative values of cardiac index (CI), mean arterial pressure (MAP), and heart rate (HR) were recorded. RESULTS The phenomenon of 'no reflow' was encountered in 35 digits of 22 patients who underwent salvage surgery due to vascular compromise. The survival rate in the revascularization group was 75%, while it was 42.1% in the replanted digits. Metaphysis level of proximal phalanx was the most common localization for 'no reflow' phenomenon. The least values of CI, MAP and HR to obtain sufficient perfusion in salvaged digits were as follows: 4.2 l.min-1.m-2, 76 mm Hg, and 83 beat·min-1, respectively. CONCLUSIONS It was demonstrated that dobutamine infusion at a rate of 4 µg·kg-1·min-1 intraoperatively and at 2 µg·kg-1·min-1 postoperatively has favorable effects on the vascular compromise derived from no reflow of proximal artery.

Abstract
We retrospectively reviewed 201 digit replantations or revascularizations that were performed between August 2007 and June 2015. Leeching therapy was used in 48 digits and was more commonly required in replanted digits. In revascularized digits, leeching was used significantly more frequently in avulsion injuries and injuries associated with fractures. Digits that were leeched for more than 4.5 days had significantly higher rates of survival of digits after replantation or revascularization. Leeching was associated with higher incidence of transfusion, higher mean number of transfusions, and longer length of stay. We conclude from this study that leeching is used more frequently after digital replantation than revascularizaion, and in revascularized digits, leeching is used more often in avulsion injury and in patients with fractures. In patients requiring leeching therapy, leaching for more than 4.5 days leads to higher rate of digital survival. Level of evidence: IV.

Abstract
BACKGROUND The success of salvage procedures for failing digital replants (FR) is poorly documented. We sought to evaluate the success of salvage procedures for FR and factors contributing to successes and failures of replants. METHODS Adult patients who presented to our center between January 1, 2000 and December 31, 2015, suffered ≥1 digital amputation(s), and underwent digital replantation were included. Preoperative, perioperative, and postoperative details were recorded. Digits were monitored postoperatively via nursing and physician assessments. The presumed reason for failure, details, and outcomes of salvage attempts were recorded for FR. Length of hospital stay and complications were also recorded. RESULTS Fifty-two patients and 83 digits were included. Fifty-two digits (63%) were compromised (arterial ischemia in 15 digits; venous congestion in 37 digits) and 48 digits had salvage therapy. Twenty-one FR (44%) were salvaged via operative (1 of 2; 50%), nonoperative (19 of 43; 44%), and combined (1 of 3; 33%) therapies. FR patients were more likely than those with successful replants to receive a blood transfusion (52 vs. 23%; p = .009) with more transfused units (3.45 ± 3.30 vs. 0.86 ± 0.95; p = .001). Length of stay was prolonged for FR patients (9 [range: 2-22] vs. 7 [range: 3-19] days; p = .039). Ultimately, 59% (49 of 83) of replants were successful, where 25% (21 of 83) were successfully salvaged. CONCLUSION Nonoperative and operative salvage therapies improve the rate of replant survival. We suggest close postoperative monitoring of all replants and active salvage interventions for compromised replants in the postoperative period.

Abstract
Medicinal leeches are extremely useful and safe in the salvage of venous outflow compromised tissue, particularly in digit replants and various forms of flaps. Although it is unusual for a partial soft tissue avulsion of the face to require medicinal leech therapy, situations may occur in which there is adequate arterial inflow but inadequate venous outflow. In such cases, medicinal leeches may play a very important role in salvaging the soft tissue segment. We report a case of a 34-year-old gentleman who showed signs of venous congestion following primary management for a traumatic nasal flap. Successful salvage of venous congestion was done using medicinal leech therapy, once daily, for 5 days. His recovery deemed satisfactory and uncomplicated. Medicinal leeches are well-known in the treatment of venous congestion or complete venous outflow obstruction in larger pedicled flaps and microvascular transfers. In trauma, it is well established that medicinal leeches are invaluable in treating venous congestion in digit replants and replantation of totally avulsed external ear segments. A limited number of other reports have demonstrated the use of medicinal leeches for salvage of other partially avulsed facial structures. Medicinal leeches have a significant role in the management of traumatic and microvascular flaps, the oral and maxillofacial surgeon should weigh the benefits of such treatment before instituting other expensive or complex treatment modalities.

Abstract
BACKGROUND Leeches were used for medical purposes as long as 2 000 years ago in ancient Egypt. In recent years the use of medicinal leeches became rather popular again, e. g. to improve blood circulation in ischemic tissue after reconstructive plastic surgery. PATIENTS AND METHODS In a single center, retrospective study 23 consecutive cases were analyzed in which medicinal leeches had been used therapeutically after plastic reconstructive surgery. All cases were categorized regarding the indication for leech therapy, the onset, the duration, the number of leeches and the number of sessions. RESULTS Among the group of patients there were 7 female and 16 male patients with a mean age of 73 ± 14 years (48-94 years) altogether. The main indications were venous congestion (12/23; 52 %) and hematoma (9/23; 39 %). Two cases were diagnosed with a necrosis of the tip of the flap and therefore received leech therapy (2/23; 9 %). The average number of leeches was 2.6 leeches/session, the number of sessions was 1.7 ± 0.8. 20/23 patients (87 %) showed a restitutio ad integrum after leech therapy, in 3/23 patients (13 %) a necrosis of the tip of the flap could not be prevented. A clinical improvement was noticed after an average of 1.1 ± 0.3 days. CONCLUSIONS The early application of medicinal leeches can improve local hemodynamic conditions. Leech therapy is a simple and effective method; the cost efficiency of the treatment is high.

Abstract
Objective: To report a case of the venous obstructive condition known as phlegmasia cerulea dolens (PCD) in the presence of heparin-induced thrombocytopenia (HIT). Case Summary: A 50-year-old white female presented to the emergency department with a 2-day history of a bluish discoloration of her toes and hands accompanied by chest pain and shortness of breath. The evident edema, tenderness on palpation, and cyanosis of the extremities were suggestive of PCD. She had been hospitalized approximately one month previously due to a fibular fracture and again within the past 2 weeks for intractable abdominal pain and nausea. During her current hospital stay, she was diagnosed with multiple venous thromboembolisms (VTEs); at the time of admission, an unfractionated heparin (UFH) drip was initiated to treat her VTEs. Due to a decreased platelet count on admission, a platelet factor 4 (PF4) antibody assay was performed and found to be positive. After discontinuation of UFH, her platelet count slowly returned to normal range. Discussion: The pathogenesis of HIT is due to formation of antibodies against the complex of heparin and PF4. HIT is characterized by a reduction in the platelet count approximately 4–14 days after the initiation of heparin therapy plus a paradoxical prothrombotic state. The typical diagnostic clues are a drop in platelet count of 50% from baseline with the initiation of heparin and a positive assay for heparin-PF4-immunoglobulin G. This condition may result in PCD, which presents as the triad of pain, edema, and cyanosis. This condition often results in venous or arterial thrombus formation. The treatment for PCD includes immediate discontinuation of heparin products and anticoagulation with a direct thrombin inhibitor. Conclusions: Thromboembolic complications such as PCD are often observed as a presenting feature of HIT. To avoid these potentially limb- and life-threatening complications, clinicians must be vigilant in their monitoring of platelets and clinical signs and symptoms of HIT while patients are on heparin therapy.

Abstract
BACKGROUND Medicinal leeches have been demonstrated to be extremely useful and safe in the salvage of venous outflow compromised tissue, particularly in digit replants and various forms of flaps. OBJECTIVE To demonstrate the utility of medicinal leeches in the salvage of venous outflow-compromised traumatic soft tissue avulsions in key facial structures. METHODS A retrospective review of 4 cases involving the external ear, nose, lip, and scalp in which apparent venous outflow compromise was present. Medicinal leeches were applied acutely in each of these 4 cases, salvaging each of the partially avulsed soft tissue segments. RESULTS Complete or near complete salvage of each soft tissue segment after using medicinal leeches. CONCLUSIONS Although it is unusual for a partial soft tissue avulsion of the face to require medicinal leech therapy, situations may occur in which there is adequate arterial inflow but inadequate venous outflow. In such cases, medicinal leeches may play a very important role in salvaging the soft tissue segment. This is particularly important in vital structures such as the ear, nose, lip, and eyelid in which acute or secondary reconstruction is complex. EBM RATING C.

Abstract
Medicinal leeches (Hirudo medicinalis) are a standard treatment for venous congestion, a complication that can occur after reconstructive surgery. If the cause of venous congestion cannot be surgically corrected, then medicinal leeches are used to temporarily increase perfusion levels and maintain physiologic requirements within the congested tissue. Leeches increase perfusion within congested tissue by actively drawing off blood as a bloodmeal. Furthermore, the leech bite continues to bleed and relieve congestion after detachment because of the anticoagulation effects of leech saliva left behind in the bite. In a porcine model, a 10 x 10 cm cutaneous flank flap was congested by clamping the venae comitantes. Four medicinal leeches were allowed to attach to the congested flap, and parameters of active feeding and passive bleeding after detachment were recorded. The average bloodmeal volume for the medicinal leeches was 2.45 ml. Average passive bleeding for the first 2 and 4 hours after leech detachment totaled 2.21 and 2.50 ml, respectively, with 90 percent of passive bleeding occurring within 5 hours after detachment. Laser Doppler imaging indicated that the spatial arrangement of surface perfusion increases were localized to a 1.6-cm-diameter circle around the leech head (bite) and corresponded well with the visual return of normal skin tones to the same area. This study provides a realistic and quantitative estimate of the spatial and volumetric characteristics of leech feeding and passive bleeding using a clinically relevant model of acute, severe congestion.

Abstract
The authors describe the design and testing of a mechanical leech device that has shown greater efficacy in alleviating venous congestion and promoting skin flap survival than previously described clinical therapies. Abdominal skin flaps (3 x 6 cm) were raised on Sprague-Dawley rats and were subjected to two ischemic events that simulated clinical venous congestion. The animals received two treatments with the device prototype during 7-day experiment (N = 9). Flap perfusion was monitored with a scanning laser Doppler imager (LDI) and was normalized to adjacent skin perfusion. Photographic images of flaps at 7 days were assessed for areas of nonnecrotic tissue, and LDI data consisted of perfusion measurements at nine time points during the 7-day experiment. The device prototype was able to promote an average survival area in the flap of 60.0 +/- 3.5%, which was not only a significant (p < 0.05) increase over previously published control groups (8.0 +/- 5.0%) that did not receive any treatment, but was a significant increase over the same treatment schedule with clinically used leeches (34.6 +/- 7.3%). At 7 days, LDI data showed flap perfusion to be 65.6 +/- 7% of adjacent skin perfusion, a significant increase over this level at the end of the second ischemic event (21 +/- 1%; p < 0.05). These results suggest that this device could be used clinically to alleviate venous congestion and to promote flap survival. The device could also be useful for prophylactic treatments and to minimize treatment delays because its long shelf-life permits immediate availability when a treatment decision is made.

Abstract
Traumatic amputation of the entire auricle is a rare occurrence. Management ideally consists of microvascular reconstruction of auricular arterial, venous, and nerve continuity. However, appropriately sized veins are often not available and venous drainage must be accomplished with leech therapy. In occasional cases where leeches are unavailable or cannot be made to attach, mechanical drainage and anticoagulation can give satisfactory drainage. The authors present a case of mechanical wick venous drainage of a complete ear replantation, resulting in virtually normal appearance and function of the ear. In addition, the ear regained normal touch and two-point sensibility, although the great auricular nerve had not been repaired.

Abstract
This study compares the effectiveness of alleviating venous congestion with mechanically-made outlets or leech therapy in promoting skin flap survival. Free flaps of abdominal skin (3 x 6 cm) were raised on Sprague-Dawley rats and subjected to ischemic events, simulating venous congestion. Animals received 1) no treatment; 2) two treatments involving two 18-gauge needle-puncture outlets; or 3) two sessions of leech therapy. Flap perfusion was monitored with a scanning laser Doppler flowmeter. Photographic images of flaps at 7 days were assessed for areas of normal tissue (n = 15), and laser Doppler flowmeter data consisted of control (n = 6), outlet (n = 6), and leech (n = 7). Both the needle-puncture outlet (40.0% +/- 9.24%) and leech treated (34.6% +/- 7.34%) groups had a significantly greater surviving skin area than untreated control flaps (8.0% +/- 5.0%), with 2 of 15 flaps receiving mechanical outlets exhibiting > 90% surviving area. After 7 days, laser Doppler flowmeter data showed greater mean perfusion in the outlet (71.7% +/- 16.8%) and leech (92.6% +/- 17.2%) treated groups, compared to controls (15.2% +/- 10.2%). There was a significant increase in perfusion in the outlet (13.3% +/- 6.2%) and leech (9.1% +/- 1.1%) treated groups from the end of secondary ischemia to day 7 (p < 0.05) compared to controls. The results suggest that two spatially separated outlets are as effective as one leech in increasing the area of surviving skin in venous congested flaps.

Abstract
We report a case in which medicinal leeches (Hirudo medicinalis) were used to rescue a traumatic nasal flap from venous congestion and loss. A healthy 18-year-old had a bicycling accident and, in addition to other facial injuries, presented with a complex full thickness nasal laceration. After he had been resuscitated and the flap sutured, he was treated with two leeches four times a day for 48 h. His recovery was satisfactory and uncomplicated. Oral and maxillofacial surgeons should be familiar with the use of leeches, as they have a small but occasionally important role in the management of both traumatic and reconstructive flaps.

Abstract
We report the successful use of leech therapy in the postsurgical management of an infant with acute venous congestion of an entire lower limb. Two days of constant leech therapy, followed by 5 days of intermittent application, decongested the affected tissues. There were no complications related to the leech therapy, and mild cutaneous hyperpigmentation was the only long-term complication of the acute venous congestion. The volume of the affected tissue may limit the success of leech therapy in cases of acute venous congestion in the limbs of adults. Nevertheless, the use of leeches to manage acute venous congestion of large portions of infants' bodies should be considered when surgical therapies are not feasible.

Abstract
The medicinal leech, Hirudo medicinalis, played a central role in the evolution of medieval and folk medicine. Today, for the first time in history, the leech actually has a real and valuable purpose in medicine as a useful adjunct for the plastic surgeon: It provides relief of venous congestion. For over 2000 years, leeches were needlessly applied for a multitude of maladies as an adjunct to blood-letting. Their use in Europe peaked between 1830 and 1850, however, shortages led to a subsequent decline in leech application. Today there is a real clinical use for leeches which had led to a resurgence in their use in plastic surgery. Plastic surgeons use leeches in microsurgery to salvage congested flaps, whose viability is uncertain due to venous congestion. We present our experience with two patients where leeches were used to treat isolated venous engorgement of the nipple following breast surgery. Leech therapy is painless, well tolerated, and does not result in significant scarring. Prompt initiation of treatment is mandatory and produces dramatic resolution of venous congestion.

Abstract
Leeches were studied for their efficacy to improve survival of venous compromised rat skin flaps. In 22 rats, bilateral epigastric island flaps were created and subjected to 6 h of venous occlusion. One flap in each animal was randomised to leech treatment, while the contralateral flap served as its own control. Flap survival, leech feeding time, weight gained by the leech and bleeding time from leech bites were measured. The area of flap survival was significantly increased in leech treated flaps compared to contralateral controls (n = 22 pairs, p = 0.03; Wilcoxon signed rank test). Weight gained in the feeding leech averaged 1.3 +/- 0.2 g (n = 18). Leech feeding time was 107 +/- 13 min (n = 18). Bleeding time from each leech bite averaged 79 +/- 12 min (n = 18). Hence, the extent of flap necrosis resulting from venous impairment can be partly diminished by leech treatment until definitive surgical venous revascularisation.

Abstract
From 1975 to 1988, replantation operations of fingers or hands were performed in 2,040 patients at the Division of Plastic and Reconstructive Surgery, Technical University Munich, Germany. The meticulous repair of blood vessels is still the most important step for a successful replantation. The liberal use of vein grafts very often makes replantations possible even in avulsion and crush injuries. The best functional results are achieved in replantations of distal finger parts, because an intact proximal interphalangeal joint and tendon apparatus guarantees almost a full range of motion. Age alone is not an exclusionary factor for replantation. Even 70 or 80 year old patients can achieve a satisfying functional result after replantation. Replantation as a matter of course is indicated in every amputation. Nevertheless, the extent of tissue damage, patient age and general health condition as well as the patient's wishes regarding a replantation have to be considered before performing a replantation. In addition, only continuous, long-term physical therapy be specialized physical therapists and the continuous postoperative attention of the surgeon ensure a satisfying result.
