Figura 2 — Herida por arma blanca de la aorta suprarrenal. Las de la arteria renal pueden repararse primariamente, o bien, resecarlas y utilizar un injerto.
Raramente podemos realizar un bypass aortorrenal utilizando un lugar distal en la pared anterior de la aorta. Sin embargo, la ligadura de la vena renal izquierda es generalmente bien tolerada, si se lleva a cabo de forma proximal y cerca de la vena cava inferior, ya que existen colaterales venosas como las venas gonadales, suprarrenales y renolumbares que mantienen el flujo venoso.
Siempre que sea posible todos los injertos deben recubrirse con peritoneo. Estos bypass tienen la desventaja de involucrar a vasos no lesionados, presentando alta incidencia de trombosis.

This alternative view was strongly supported by the in vitro regenerative studies performed mainly by Marinesco and Minea Marinesco and Minea, , The current perspective on the subject is a concept of molecular differentiation between both trophic and tropic cues in growing and re-growing of axons Tessier-Lavigne and Goodman, ; de Castro, At the beginning of the s, following the initial descriptions of nerve regeneration by Langley Langley, , , de Castro undertook complex experiments including reinnervation and crossed anastomosis between autonomic motor fibers and sensory ganglia.
He as well studied the behavior in vitro of explants from ganglia de Castro, , , , , but these studies were mostly focused on subjects outside the scope of the current review.
In his research on experimental re-innervation and regeneration, de Castro produced several of his most memorable histological preparations and drawings reflecting the diversity of cells and the complex relationships between neurons Figure 2 ; de Castro, , The publication of these intense and meticulous studies had important consequences. Some of them are easily tangible.

This recognition did not weaken: it would last until the death of Cajal in and would determine several of the milestones in the scientific trajectory and human life of Fernando de Castro. First works of Fernando de Castro in the structure of the peripheral nervous system. The typewritten figure legend in Spanish for the defense of the thesis is conserved for the reader, as well as the signature from de Castro at that time.
This figure was published in de Castro This schema was published in de Castro c , The Second Conquest: The Fine Structure of Autonomic Ganglia Undoubtedly impelled by the success of his research on the histology of the human somatic sensory ganglia, as well as by the evident lack of studies with neurofibrillary methods at that time, Fernando de Castro re-assumed a research line which he briefly explored in the very first years of his scientific career de Castro, : a serious study of the histology of autonomic ganglia.
This research line can be considered as completed with the publication of a monograph and a series of shorter articles which includes maybe the most important comparative study between mammalian species including primates and humans to that date de Castro, a , b , , , although important morpho-functional observations derive from works mainly devoted to other subjects than sympathetic ganglia for details about the latter three studies, see below de Castro, a , b , , ; de Castro and Herreros, ; Figure 3.
De Castro also affirmed that these dendritic nests, far from being accidental arrangements, are receptive sites for specific synaptic contacts from preganglionic fibers de Castro, b. In each ganglion cells of these three types are intermingled and distributed in an apparent arbitrary way de Castro, b , , , and each type of preganglionic fiber contacts exclusively one type of ganglionic cell Billingsley and Ranson, ; de Castro, a , a , b , , which coincides with electrophysiological recordings showing four different potential waves in sympathetic ganglia Bishop and Heinbecker, ; Eccles, a , b , c.
Thus, the sensory nature of these fibers, as proposed originally by Dogiel, could be discarded.
Posterior denervation studies demonstrated that the number of intraganglionic synapses is significantly larger than that of terminal boutons de Castro and Herreros, Developmental evidence drove de Castro to suggest that the apparent disorder and arbitrary distribution of ganglionic cells derive from germinative centers or spheres disseminated within the ganglia de Castro, a , a , b.
For example, he clearly stated that the ganglia are literally invaded by mesenchymal structures that lie interposed between the ganglionic neuronal components somata, dendrites, axons. In the ganglia the Schwann cells behave as the oligodendrocytes in the CNS, but de Castro also suggested that expansions emanated by Schwann cells form the intermediate portions of synapses, i.
It should be quoted here that de Castro, together with B.
Lawrentjew, was among the first scientists specifically studying regeneration of synaptic contacts in the sympathetic system Lawrentjew, , a , b ; de Castro, In this series of scientific articles, de Castro showed in detail the cytoarchitecture of sympathetic and parasympathetic autonomic motor ganglia in humans, in other primates and in several large mammals. At that time the exhaustive and expert works of Fernando de Castro in the field of the histology of somatic sensory and autonomic ganglia had gained international recognition.
The most clear example of this came by hand of the famous American neurosurgeon and neuropathologist Wilder S.
Sympathetic neurons by Fernando de Castro. This image was published in de Castro B Partial view of a sympathetic ganglion normal condition of an adult cow de Castro, C Portion of a sympathetic ganglion with regenerated preganglionic fibers a after a vagus-sympathetic crossed anastomosis de Castro, ; A is part of Archive Fernando de Castro.
But at that moment, a young fellow, Fernando de Castro, came in. Cajal left us then and I did stay on to talk with de Castro.
The painter came to Spain because he wanted to visit exiled last Austro-Hungarian empress, Zita, exiled in Spain.This research line can be considered as completed with the publication of a monograph and a series of shorter articles which includes maybe the most important comparative study between mammalian species including primates and humans to that date de Castro, a , b , , , although important morpho-functional observations derive from works mainly devoted to other subjects than sympathetic ganglia for details about the latter three studies, see below de Castro, a , b , , ; de Castro and Herreros, ; Figure 3.
Introduction Today it is common knowledge that in Vertebrates an autonomic or vegetative nervous system governs the visceral components of the body and controls the internal environment in close integration with the somatic nervous system.
