Pulmonary reimplantation response in single-lung transplantation.

We studied the characteristics of the pulmonary reimplantation response (PRR) in single-lung transplantation (SLT), and detailed the occurrence, evolution, prognosis and risk factors of this complication. Forty single-lung transplant recipients were studied. Twenty four patients developed hypoxaemia and allograft infiltrates consistent with the PRR. In 40% of the cases hypoxaemia was severe, precluding weaning and requiring prolonged mechanical ventilation with high fractional inspiratory oxygen (FIO2). The mean duration of ventilation was 7 days (range 1-19 days). Clearing of the chest radiographs was progressive, with complete resolution between 6 and 21 days. In all cases, the pulmonary arterial wedge pressure was normal (6 +/- 2 mmHg) suggesting low pressure oedema. Sampling of the pulmonary oedema fluid revealed that the ratio of protein concentration in oedema fluid to that in serum exceeded 0.5. In patients with severe PRR (40% of cases) clinical, radiographic and haemodynamic abnormalities were identical to adult respiratory distress syndrome (ARDS), but the prognosis was more favourable with no death directly related to PRR in our patients. The mean duration of graft ischaemia of the oedematous grafts (241 +/- 103 min) was significantly longer than that of nonoedematous grafts (155 +/- 71 min). These date suggest that prolongation of graft ischaemia increased the incidence of PRR.

Off-pump reimplantation of anomalous origin of the right coronary artery.

A 30-year-old man was diagnosed to have an anomalous origin of the right coronary from the pulmonary artery. Through a mini-sternotomy, without extracorporeal circulation, reimplantation of the anomalous origin of the right coronary artery from the pulmonary artery to the aorta was successfully performed. This is a successful case of off-pump cardiac correction of this type of isolated anomaly, using a minimally invasive approach.

Bionic larynx: electronic control of the reimplanted organ in the dog.

Complete rehabilitation of paralyzed head and neck structures has been difficult, and attempts at reinnervation of striated muscles have not consistently succeeded. Recent studies have shown that disabled muscles can be electronically "paced." This, together with recent developments in microelectronics, has led to the concept of the Bionic Larynx. The current experiments involve transposed nerve-muscle pedicles used to selectively reinnervate larynges which were denervated, entirely detached from the animal except for their vascular supply, and then reimplanted. These pedicles were later stimulated using a potentially implantable "pacing unit." It was possible to selectively control the critical functions of the larynx, using as stimuli physiological events that are preserved even when the vocal folds are paralyzed or uncoordinated. Although laryngeal transplantation in humans remains theoretical, these studies show that it could be feasible in the future.

Acute pulmonary edema after lung transplantation: the pulmonary reimplantation response.

BACKGROUND: Although the development of noncardiogenic pulmonary edema or pulmonary reimplantation response (PRR) after lung transplantation has been well described, the incidence has not been established and the relationship of PRR to clinical risk factors has not been analyzed. STUDY OBJECTIVES: (1) To describe the incidence of PRR in lung transplant recipients, (2) to identify the predictors of PRR, (3) to examine the correlation of suspected predictors with the severity of PRR, and (4) to evaluate the impact of PRR on morbidity and mortality of lung transplant recipients. DESIGN: Retrospective review of clinical records and radiographic studies. SETTING: Tertiary care referral center. PATIENTS: Ninety-nine consecutive patients with end-stage lung disease undergoing lung transplantation between February 1990 and October 1995. METHODS: Review of clinical records and postoperative chest radiographs of all lung transplant recipients to identify patients who experienced PRR. Chest radiographs of patients with PRR were graded for severity on a scale of 0 (none) to 5 (very severe). Demographic, pre- and perioperative factors were also evaluated along with short- and long-term survival of patients with PRR. RESULTS: Fifty-six of 99 lung transplant recipients (57%) experienced PRR. The median ischemia time of patients with and without PRR was 168 and 180 min, respectively (p = 0.62). The incidence of PRR was 51% in patients without preoperative pulmonary hypertension, 78% in mild to moderate pulmonary hypertension, and 58% in patients with severe pulmonary hypertension (p = 0.10). Incidence and severity of PRR was similar in patients receiving right, left, or double-lung transplantation. Similarly, age and sex of the recipients and underlying lung disease did not affect the incidence or severity of PRR. The incidence and severity of PRR was higher in patients undergoing cardiopulmonary bypass during lung transplantation. Patients with PRR had prolonged duration of mechanical ventilation and ICU stay. Overall, PRR did not affect the survival of the patients. However, survival of female lung transplant recipients was significantly better than male recipients (median survival, 60 vs 21 months; p = 0.02). CONCLUSIONS: Acute pulmonary edema or PRR occurs frequently (57%) after lung transplantation. In this series, PRR was not associated with a prolonged ischemia time, preoperative pulmonary hypertension, the type of lung transplant, underlying lung disease, or age or sex of recipients. However, use of cardiopulmonary bypass during surgery was associated with increased incidence and severity of PRR. Also, the development of PRR resulted in prolonged mechanical ventilation and a longer ICU stay, but did not affect survival. Female lung transplant recipients survived significantly longer than male recipients. The reason for this difference in survival is unclear.

Laparocopic ureteral reimplantation in ureteral stenosis after gynecologic laparoscopic surgery.

Pelvic surgery is the most common cause of iatrogenic ureteral injury, and traditionally repair of such injuries requires laparotomy. We report the case of a 48-year-old woman with an iatrogenic ureteral injury after laparoscopic ophorectomy which was laparoscopically reimplanted using the Lich-Gregoire technique. Total operating time was 150 minutes and estimated blood loss was 100 mL. Two months after surgery she is asymptomatic with normal renal function.

The extruded talus: results of reimplantation.

BACKGROUND: There is considerable debate regarding the appropriate treatment of the extruded talus regardless of the presence of a fracture. The purpose of this study was to report the clinical results, complications, and functional outcome following reimplantation of the traumatically extruded talus. METHODS: A database of 119 patients with an open injury of the talus occurring between 1995 and 2003 at a level-I trauma center was reviewed to identify patients with a complete talar extrusion. Demographic, imaging, and treatment data were obtained from a review of the medical records. Follow-up was undertaken during clinic visits or by telephone. Preoperative and follow-up radiographs were reviewed to identify posttraumatic arthritis, osteonecrosis, or talar collapse, and the Musculoskeletal Functional Assessment was used to assess functional outcome. RESULTS: Twenty-seven patients were identified. A minimum follow-up of one year (average, forty-two months) was obtained for nineteen patients. Infection and the need for a secondary surgical procedure were the primary determinants of clinical outcome. Two of the nineteen patients had documented infections: one had developed at two weeks and one, after a calcaneal osteotomy at nineteen months. Twelve patients had no subsequent surgery, and seven had subsequent procedures (range, one to four procedures). No patient underwent a delayed amputation. The average Musculoskeletal Functional Assessment score at the time of follow-up was 29.8 (range, 5 to 59). With the numbers studied, no association was found between functional outcome and the following variables: ipsilateral lower-extremity injury, associated talar fracture, secondary procedures, osteonecrosis, or age. CONCLUSIONS: While functional outcome is difficult to assess, salvage of the extruded talus appears to be a relatively safe operation, with a minimal risk of infection, which allows maximal flexibility in aftercare by preserving the most normal ankle anatomy possible.

Successful tubal reimplantation after rupture of the uterus.

A 29-year-old woman with primary infertility caused by bilateral isthmical tubal block was operated upon with bilateral cornual resection and tubal implantation. After one uncomplicated childbirth a second fullterm pregnancy ended in fetal catastrophe: the uterus ruptured at both sites of tubal implantation and a stillborn fetus was delivered by emergency cesarean section. One oviduct was detached from the uterus and the other one had to be removed. However, the maternal condition never became critical. Later on, a second tubal reimplantation was performed on the remaining side, and after a first-trimester spontaneous abortion a second healthy infant was born at elective cesarean section.

Reimplantation of isolated skin flaps in dogs with circulation maintained through artificial heparinized shunts.

In an experimental study in dogs, skin flaps with an axial vascular pattern were completely isolated and reimplanted. Circulation was maintained through arterial and venous shunts using silicone rubber tubes or heparinized polyethylene tubes. Six out of 8 flaps healed uneventfully. In 4 of the surviving flaps, both the artery and the vein were shunted. Only the artery was shunted in two of the flaps.

Spinal nerve root repair and reimplantation of avulsed ventral roots into the spinal cord after brachial plexus injury.

OBJECT: The authors review the first series of 10 cases in which injured intraspinal brachial plexus were surgically repaired. They describe the technique of spinal cord implantation or repair of ruptured nerve roots, as well as patient outcome. METHODS: Spinal root repair/implantation was performed from 10 days to 9 months postinjury. There were nine male patients and one female patient. Postoperatively in most cases, regeneration of motor neurons from the spinal cord to denervated muscles could be demonstrated. The first signs of regeneration were noted approximately 9 to 12 months postoperatively. Useful function with muscle power of at least Medical Research Council Grade 3 occurred in three of 10 cases. Magnetic brain stimulation studies revealed a normal amplitude and latency from the cortex to reinnervated muscles on surgically treated and control sides. A certain degree of cocontraction between antagonistic muscles (for example, biceps-triceps) compromised function. With time there was a reduction of cocontractions, probably due to spinal cord plasticity. In these cases there was also, surprisingly, a return of sensory function, although the mechanism by which this occurred is uncertain. Sensory stimulation (thermal and mechanical) within the avulsed dermatomes was perceived abnormally and/or experienced at remote sites. There was some return of patients' sense of joint position. CONCLUSIONS: A short time lag between the accident and the surgery was recognized as a significant factor for a successful outcome. Reimplantation of avulsed nerve roots may be combined with other procedures such as nerve transfers in severe cases of brachial plexus injury.

[A new method for combined auto-alloplastic tooth reimplantation with a parallel A1203-ceramic root].

The operative procedure for partially replacing the root with A12O3 ceramic represents a good possibility for preserving teeth in which the pulpa is devitalized. The method used in connection with the well known autoplastic reimplantation not only presents an alternative to the traditional apicoectomy but also provides additional stabilization of the tooth by lengthing the root with cocotostabile and biocompatible A1203 ceramic. The method was tested in humans and monkeys. Argumentation was based on histological examination via light microscopy.

Carotid endarterectomy with patch closure versus carotid eversion endarterectomy and reimplantation: a prospective randomized study.

BACKGROUND: Although carotid eversion endarterectomy (CEE) has obtained consensus providing excellent early and late results, conventional carotid endarterectomy (CEA) with or without patching continues to be considered the gold standard surgical procedure. The few studies published to date comparing CEE with CEA in a small series of patients have failed to show substantial advantages of one technique over the other, and further randomized comparative studies are still required. The purpose of this study was to compare the outcome of CEA with routine patch closure (CEAP) with that of CEE and reimplantation (CEER) of the internal carotid artery in the common carotid artery. METHODS: Three hundred thirty-six primary CEAs performed in 310 patients were randomized into 2 groups, 167 CEAPs and 169 CEERs. Surviving patients underwent duplex ultrasound scan control at 30 days, 6 months, 12 months, and every postoperative year thereafter. The mean follow-up was 34 months (range, 1 to 69 months). Demographic characteristics, risk factors, associated diseases, and indications for surgery were comparable in the 2 groups. RESULTS: Although the rate of intraoperative electroencephalogram changes was comparable in the 2 groups, the incidence of shunting was statistically higher in the CEAP group (28.1% vs 1.2%, P < .00001). The carotid cross-clamping time was significantly lower in the CEER group (P = .01). Although all deaths were in the CEAP group, the overall perioperative death and stroke-related death rates were comparable in the 2 groups. The perioperative stroke rate was statistically higher in the CEAP group (2.9% vs 0%, P = .03). Although the recurrent stenosis rate was comparable in the 2 groups (1.2% vs 0%), the CEAP group had a statistically higher rate of combined recurrent stenoses and occlusions (4.9% vs 0%, P = .003). The late mortality rate was similar in both groups. CONCLUSIONS: Although the outcome of CEAP in this series is consistent with that of the main reported trials, the CEER procedure is less likely than CEAP to cause perioperative stroke and death and seems superior in reducing the incidence of recurrent stenosis and late occlusive events.

Salmonella infection in total hip replacement--report of successful reimplantation and review of the literature.

A case of Salmonella enteritidis group C infection following total hip replacement was treated by resectional arthroplasty and appropriate antibiotics. Total hip replacement with reimplantation of an antibiotic-impregnated cemented hip prosthesis was performed five months later. The postoperative course was smooth and hip function was good, without any sign of infection recurrence throughout 10 years of follow-up. The treatment protocol and clinical results are discussed along with a review of the literature.

[Reimplantation lesion in the postoperative period of lung transplantation. Incidence, predictive factors, prognosis and outcome. The Lung Transplantation Group of Vall d'Hebron University General Hospital].

BACKGROUND: Reimplantation disease (RD) is a postoperative complication in lung transplantation. It is defined as hypoxemia (PaO2/FiO2 ratio < 150 mmHg), radiologic infiltrates and decrease of lung compliance. The aim of the study was to analyze the incidence, predictive factors, prognosis and outcome of the patients with RD. PATIENTS AND METHOD: 49 patients submitted to lung transplantation (June 1991-December 1996) were admitted in our intensive care unit (ICU). Donor and recipient conditions, surgical parameters and outcome in ICU were analyzed. Mann-Whitney, Kruskall-Wallis, Fisher, Pearson and ANOVA-Friedman tests were used for statistical analysis according to the different variables. RESULTS: 49% of the patients (29/49) developed RD, which was influenced neither by lung disease, nor by the kind of transplantation or by ischemia time. All patients with a long surgical time developed RD, versus only 41% in those where surgery was undertaken in a shorter period of time, OR: 2.8 (1.5-5.7; p = 0.0016). The patients with RD improved showing a PaO2/FiO2 ratio of 176 and 235 mmHg at 24 and 48 h respectively (ANOVA, p < 0.00001). The patients with RD needed 14 days of mechanical ventilation versus 7 days in those without RD (p = 0.013). There were no statistically significant differences in stay and mortality in ICU. CONCLUSIONS: RD is a common complication in the postoperative phase of lung transplantation. It is present in almost all the patients with long surgical time. Almost all of them improve, with the same survival but a longer period of mechanical ventilation.

Reimplantation of freeze-treated and saline-treated mandibular bone.

Mandibular bone devitalized by freezing after removal from the body and subsequently reimplanted was observed for its potential to reunite and grow in comparison to a similar saline-treated section of bone from the same animal. After a year, there were no significant discernible clinical or histological differences between the slaine-treated and the frozen bone. Approximately the same amount of histologically indistinguishable bone formed in either instance. The results suggest that a partially resected mandible subjected to freezing maintains the same capacity to act as an autogenous graft as does bone partially devitalized by immersion in saline solution.

Preservation of renal function in reimplantation of renal artery of abdominal aortic aneurysm.

Intraoperative administration of diuretics and renal hypothermia with cold (4 degrees C) heparinized Ringer's lactate were useful methods for preserving renal function during warm ischemia time. 54-year and 74-year-old men were diagnosed as abdominal aortic aneurysm. Their left renal and accessory left renal arteries originated from the border zone of the aneurysm. We reported two cases of reimplantation of the renal artery in abdominal aortic aneurysm without deterioration of renal function.
