Referred pain to the ipsilateral forehead and orbit: An unusual phenomenon during bronchial artery embolization
CardioVascular and Interventional Radiology, 1999Co-Authors: Ravi Ramakantan, Manoj Ketkar, Krishna Maddali, Hemant DeshmukhAbstract:Purpose: We report an unusual pattern of referred pain to the ipsilateral forehead and orbit observed during bronchial artery embolization (BAE) for massive hemoptysis due to Pulmonary tuberculosis (TB) and postulate possible neural mechanisms for its occurrence. Methods: Seven men, from a series of 194 patients (171 men, 23 women) undergoing BAE (right bronchial artery 4, left 3) with gelatin sponge for control of massive hemoptysis due to Pulmonary TB form the subject of this report. Results: Embolization was successful in achieving control of hemoptysis in these patients and there were no complications following the embolization. Transient, moderately severe, ipsilateral supraorbital and/or retroorbital pain occurred only during the injection of the gelatin sponge contrast mixture into the bronchial artery. The pain did not occur during the injection of heparinized saline or ionic contrast medium. Conclusions: Referred pain during BAE is an unusual phenomenon. Acute vessel distension triggering visceral sensations is probably the causative mechanism. Sympathetic afferents from the bronchi coursing through the posterior Pulmonary Plexus eventually pass to the trigeminal ganglion via the carotid sympathetic chain. The ophthalmic and maxillary divisions of the trigeminal nerve then mediate pain sensation to the ipsilateral forehead and orbit. Similarly, parasympathetic afferents from the Pulmonary Plexus crossing the nucleus of the spinal tract of the trigeminal nerve may be responsible for interexchange of impulses to the neurons in this nucleus. Sensory fibers of the ophthalmic and maxillary nerves relaying in this nucleus are then involved in this pain being referred to the forehead and orbit.

Molecular Pathways and Animal Models of Total Anomalous Pulmonary Venous Return
Congenital Heart Diseases: The Broken Heart, 2016Co-Authors: Robert E. Poelmann, Adriana C. Gittenberger-de Groot, Monique R.m. Jongbloed, Marco C. DeruiterAbstract:The venous pole of the heart where the Pulmonary veins will develop encompasses the sinus venosus and the atrium. In the 4th week of development, the sinus venosus consists of a left and a right part receiving blood from the common cardinal vein, the omphalomesenteric and umbilical veins. Asymmetrical expansion of the common atrium corresponds with a rightward shift of the connection of the sinus to the atrium. The right-sided part of the sinus venosus including its tributing cardinal veins enlarge to form the caval veins that will incorporate into the right atrium. The left-sided part in human development largely obliterates and remodels to form the coronary sinus in adults. In approximately the same time-window (4th–5th week), a splanchnic vascular Plexus surrounds the developing lung buds (putative lungs) with a twofold connection. Of note, during early developmental stages, the primary route of drainage from the Pulmonary Plexus is towards the systemic veins and not to the heart. After lumenization of the so-called mid-pharyngeal endothelial strand (MPES), the first Anlage of the Pulmonary vein, the common Pulmonary vein can be observed in the dorsal mesocardium, and the primary route of drainage will gradually change towards a cardiac drainage. The splanchnic Pulmonary venous connections with the systemic cardinal veins will gradually disappear during normal development. In case of absence or atresia of the MPES, the Pulmonary-to-systemic connections will persist, clinically resulting in total anomalous Pulmonary venous return (TAPVR). This chapter describes the developmental processes and molecular pathways underlying anomalous Pulmonary venous connections.
