RESUMO

We report a cadaveric case of unusual innervation pattern of the right calf and ankle. During dissection of an 82 years-old, formalin-fixed, male cadaver, the posterior femoral cutaneous nerve was found providing sensory supply to the lateral knee region, while it terminated at the level of the ankle. Moreover, the medial sural cutaneous nerve did not anastomose with a peroneal communicating branch and it continued as the lateral dorsal cutaneous nerve of the foot. In cases that the peroneal communicating branch is absent, the medial sural cutaneous nerve is called sural nerve. Additionally, the lateral sural cutaneous nerve travelled over the calf crossing the sural nerve at its middle and thus, providing sensory supply to the upper lateral calf and the lower medial aspect of the calf and ankle. This peculiar sensory supply may cause diagnostic hazard in cases of nerve injury with neurological symptomatology, whereas due to the presented variability, nerves are prone to iatrogenic injury during procedures in the area

RESUMO

A pesar de que la prostatectomía radical constituye un tratamiento con intención curativa que ha demostrado ser eficaz en muchos de nuestros pacientes con cáncer prostático, aún se asocia a una morbilidad importante, que incluye, entre sus exponentes más destacados, la disfunción eréctil postoperatoria. La potencia posterior a la intervención puede estar influenciada por muchos factores entre los que destacan la presencia de una función eréctil adecuada previa a la cirugía, la edad del paciente, el estadio de la enfermedad en el momento del tratamiento, la experiencia del cirujano y, por supuesto, las variaciones anatómicas interpersonales.Durante las últimas décadas, el conocimiento exacto de la neuroanatomía de la pelvis masculina ha adquirido una gran importancia, tanto para el estudioso de la anatomía humana como para el cirujano pélvico. Por eso, las técnicas anatómicas de preservación neurovascular han propiciado una disminución del número de complicaciones relacionadas con la lesión de estas estructuras. Este artículo presenta una breve descripción del sustrato neuroanatómico de los haces neurovasculares junto a una detallada compilación de las diferentes técnicas quirúrgicas descritas para su preservación durante la prostatectomía radical retropúbica(AU)


Although radical prostatectomy is a curative therapy that has proven effective in many of our patients with prostate cancer, it is still associated with significant morbidity, which includes postoperative erectile dysfunction among its leading exponents. Potency after the intervention may be influenced by many factors, among which, presence of adequate erectile function before surgery, patient’s age, stage of disease at the time of treatment, surgeon’s experience and, of course, interpersonal anatomical variations may be pointed out.In recent decades, the exact knowledge of the neuroanatomy of the male pelvis has become very important, for both the student of human anatomy and the pelvic surgeon. Therefore, the anatomical nerve sparing techniques have led to fewer complications related to the injury of these structures. This article presents a brief description of the neuroanatomical substrate of the neurovascular bundles along with a detailed compilation of the different surgical techniques for their preservation during radical retropubic prostatectomy(AU)
