ABSTRACT
Una de las infecciones virales más comunes -sobretodo en personas de mayor edad- es el Herpes Zóster (HZ). Su característica clínica, hace sospechar al médico de forma temprana, para otorgar un tratamiento adecuado y oportuno. Dentro de las complicaciones más frecuentes se encuentran las sensitivas, como la neuralgia postherpética.1 Sin embargo, existen un grupo de complicaciones motoras de menor incidencia, como lo es la Pseudohernia abdominal. Ésta corresponde a una paresia segmentaria, que se manifiesta como una protrusión de la pared abdominal sin un defecto real, que aumenta con maniobras de valsalva.1 Generalmente se puede presentar en hombres, mayores de 60 años, inmunosuprimidos o con neoplasias hematológicas.1,2,3 El diagnóstico es clínico, aunque se puede confirmar con estudio imagenológico, que evidencie una musculatura de la pared abdominal adelgazada con respecto a la contralateral y que descarta un orificio herniario por un defecto estructural. 2 La electromiografía también puede jugar un rol al evidenciar anormalidades en la conducción nerviosa. 2 La pseudohernia por HZ tiene un buen pronóstico en la mayoría de los pacientes con recuperación completa: entre 2-18 meses. 3 Su principal riesgo es la pseudobstrucción intestinal, que se puede manifestar como constipación.2,4 En el siguiente reporte de caso, se analiza a la pseudohernia abdominal como complicación motora infrecuente del HZ y sus características.
One of the most common viral infections -especially in elderly- is Herpes Zoster (HZ). Its clinical characteristic makes the doctor suspect early, to grant adequate and timely treatment. Among the most frequent complications are the sensitive ones, such as postherpetic neuralgia1 . However, there is a group of motor complications of lower incidence, such as abdominal pseudohernia. This corresponds to a segmental paresis, which manifests as a protrusion of the abdominal wall without a real defect that increases with valsalva maneuvers1 . It can generally present in men, older than 60 years, immunosuppressed or with hematological neoplasms1,2,3, The diagnosis is clinical, although it can be confirmed with an imaging study, which shows a thinner abdominal wall musculature with regard to the contralateral wall, and which rules out a hernial orifice due to a structural defect2 . Electromyography can also play a role in show abnormalities in nerve conduction2 . HZ pseudohernia has a good prognosis in most patients with complete recovery: between 2-18 months.3 Its main risk is intestinal pseudoobstruction, which can manifest as constipation2,4. In the following case report, abdominal pseudohernia is analyzed as a rare motor complication of HZ and its characteristics.

BACKGROUND: There are several techniques for harvesting the pedicled transverse rectus abdominis myocutaneous (TRAM) flap after mastectomy in breast cancer patients. We examined the whole muscle with partial sheath sparing technique and determined factors associated with its complications and oncological outcomes. METHODS: We retrospectively reviewed the results of 168 TRAM flaps performed between January 2003 and December 2010, focusing on complications and oncologic outcomes. RESULTS: Among the 168 pedicled TRAM flap procedures in 158 patients, flap complications occurred in 34%. Most of the flap complications included some degree of fat necrosis. There was no total flap loss. Flap complications were associated with elderly patients and the presence of major donor site complications. Abdominal bulging and hernia occurred in 12% of patients. The bi-pedicled TRAM flap and higher body mass index (BMI) were significant factors associated with increased donor site complications. Seven patients (4%) developed loco-regional recurrence. Within a median follow-up of 27 months, distant metastasis and death occurred in 6% and 4% of patients, respectively. CONCLUSIONS: The pedicled TRAM flap using the whole muscle with partial sheath sparing technique in the present study is consistent with the results from previous studies in flap complication rates and oncological outcomes.
