Background: Burn scar reconstruction is extremely challenging, even for the most proficient reconstructive surgeon. Within the arsenal of tools at the plastic surgeon’s disposal, tissue expansion provides an efficient modality for reconstruction despite the reported complication rates. 

Objectives: To critically review our experience with tissue expansion for burn scar reconstruction, comparing particularly the adult and pediatric populations.

Methods: We conducted a retrospective study of the outcomes of patients who underwent burn scar reconstruction with tissue expansion at Hadassah Medical Center between January 2003 and July 2012. The data included patient age, anatomical site of expansion, number of procedures, and associated complications. The outcomes of the above-mentioned populations were also compared with those in a control group of patients undergoing reconstruction with tissue expansion for indications other than burn scars. 

Results: Sixty-seven tissue expansion procedures were carried out in 50 patients, 42 in the pediatric population (< 16 years of age) and 25 in the adult population. Complications were observed in 10 of the 42 pediatric procedures (23.8%) and in 3 of the 25 adult procedures (12%). This difference was found to be statistically significant. When the complication rate for each population was compared to its control group (tissue expansion for indications other than burn scar reconstruction, such as reconstruction for motor vehicle accident scarring, congenital nevi, or vascular malformations), no statistically significant difference was found between them (complication rates 19.8% and 12.5%, respectively). Furthermore, there was no statistically significant difference in complication rates between the different anatomical areas of expansion within both populations undergoing burn scar reconstruction. Most of the complicated cases completed successful reconstruction.

Conclusions: Tissue expansion is a useful surgical tool in post-burn scar reconstruction, both in the adult and pediatric populations and in all anatomic sites, despite consistently high complication rates, especially in the pediatric population. This complication rate is not higher than in patients undergoing tissue expansion for indications other than burn scar reconstruction. 

Background: There are two main approaches to breast reduction surgery today: the traditional long scar ("Wise-pattern") technique and the more recent short ("vertical") scar technique, which is becoming more popular. During the last two decades there has been a gradual shift between the two techniques, including in our institute.

Objectives: To evaluate the evidence behind this obvious trend.

Methods: We retrospectively collected data from archived hospital charts of all patients who underwent breast reduction surgery during the period 1995–2007. Epidemiological, clinical and postoperative data were analyzed and compared between patients who were operated on by means of the short scar vs. the long scar techniques.

Results: During the study period 91 patients underwent breast reduction surgery in our department: 34 with the Wise-pattern breast reduction technique and 57 with the short-scar procedure. There was no significant difference in operative and postoperative data, including length of hospital stay. In some of the categories there was even a slight advantage (but not statistically significant) to the former. The only significant difference was the size of reduction, with a tendency to prefer the long scar technique for larger reductions; however, with gained experience the limit for short scar reductions was gradually extended to a maximum of 1470 g.

Conclusions: We noticed a sharp increase in the safe and uneventful practice of the short scar technique in breast reduction in our institute for removing ≤ 1400 g – especially in young women without extreme ptosis. This observation, together with other advantages, namely, reduced scar length, prolonged shape preservation and better breast projection, support use of this technique.
 

Background: For patients with ventricular tachyarrhythmias, implantable cardioverter defibrillators are a mainstay of therapy to prevent sudden death. However, ICD[1] shocks are painful, can result in clinical depression, and do not offer complete protection against death from arrhythmia. Radiofrequency catheter ablation of ventricular tachycardia in the setting of ischemic cardiomyopathy has emerged recently as a useful adjunctive therapy to ICD.

Objectives: To assess the feasibility, safety and efficacy of our initial experience in ablation of scar-related VT[2].

Methods: Eleven patients (all males, mean age 71 ± 8 years) with drug-refractory ischemic VT were referred to our center for scar mapping and ablation procedures using the CARTO navigation system.

Results: Eleven clinical VTs (mean cycle length 436 ± 93 ms) were induced in all patients. An endocardial circuit, identified by activation, entrainment and/or pace mapping, was found in eight patients with stable VT. These patients were mapped and ablated during VT. Three patients had predominantly unstable VT and linear ablation lesions were performed during sinus rhythm. Acute success, defined as termination of VT and or non-inducibility during programmed electrical stimulation, was found in 9 patients (82%). During follow-up, a significant reduction in tachyarrythmia burden was observed in all patients who had successful initial ablation, except for one who had recurrence of VT 2 days after the procedure and died 2 weeks later.

Conclusions: Ablation of ischemic VT using electroanatomic scar mapping is feasible, has an acceptable success rate and should be offered for ischemic patients with recurrent uncontrolled VT.

Background: Tissue expansion is a well-recognized technique for reconstructing a wide variety of skin and soft tissue defects. Its application in the pediatric population has enabled the plastic surgeon to achieve functional and aesthetic goals that were previously unobtainable.

Objectives: To review the use of tissue expansion in the pediatric population, with particular emphasis on indication, operative technique, regional considerations and how to avoid complications.

Methods: We retrospectively reviewed data on 103 expanded flap reconstructions performed in 41 pediatric patients during the period 2003–2006. Tissue expanders were placed on a subcutaneous plane above the fascia and inflated weekly. The expanded skin was used as a transposition flap or a full thickness skin graft for the reconstruction of the involved area. Forty-three tissue expanders were inserted to the head and neck in 21 patients, 45 were inserted to the trunk in 13 patients and 15 were inserted to the groin and lower extremity in 8 patients. Twenty-eight patients had one round of tissue expansion, while 13 patients had two to six rounds. A plastic surgeon, medical student and a lawyer reviewed the patients' photographs and evaluated their aesthetic outcome:

Results: Eighty-six percent of the head and neck reconstructions and 40% of the trunk and extremity reconstructions were graded as having excellent aesthetic outcome, and 11% of the head and neck reconstructions and 37% of the trunk and extremity reconstructions were graded with good aesthetic outcome. The remaining patients were graded with moderate outcome. None of our patients was graded as poor aesthetic outcome. Complications included infection in 6 patients (6%), extrusion in 3 (3%), hematoma in 2 (2%), flap ischemia in one patient (1%), and expander perforation after percutaneous stabbing in one patient (1%).

Conclusions: Tissue expansion is an efficient and valuable technique for reconstruction of large skin lesions and scars.

Background: Uterine rupture is a catastrophic obstetric complication, most often associated with a preexisting cesarean section scar. Although a vaginal birth after a cesarean is considered safe in modern obstetrics, it is not known whether repeated VBACs increase the risk of rupture, or whether the first VBAC proves the strength and durability of the scar, predicting further successful and less risky vaginal deliveries.

Objectives: To evaluate the effect of repeated vaginal deliveries on the risk of uterine rupture in women who have previously delivered by cesarean section.

Methods: In this retrospective study, 26 VBAC deliveries complicated by uterine rupture were matched for age, parity, and gravidity with 66 controls who achieved VBAC without rupture. The histories, demography, pregnancy, labor and delivery records, as well as neonatal outcome were compared.

Results: We found that the risk of rupture decreases dramatically in subsequent VBACs. Of the 40 cases of uterine rupture recorded during the 18 year study period, 26 occurred during VBAC deliveries. Of these, 21 were complicated first VBACs. We also found that the use of prostaglandin-estradiol, instrumental deliveries, and oxytocin had been used significantly more often during deliveries complicated with rupture than in VBAC controls.

Conclusions: Once a woman has achieved VBAC the risk of rupture falls dramatically. The use of oxytocin, PGE2 and instrumental deliveries are additional risk factors for rupture, therefore caution should be exerted regarding their application in the presence of a uterine scar, particularly in the first vaginal birth after cesarean.
