Superficial venous arterialization with the great saphenous vein in situ: a single-center experience.

Background: Arterialization of the dorsal venous arch of the foot is a technique indicated in cases of critical lower limb ischemia that do not have a distal bed that is adequate to enable conventional treatment such as revascularization, angioplasty, or clinical treatment. Objectives: The purpose of this study is to present the result of arterialization of the venous arch of the foot in 16 patients who underwent treatment with this technique. Methods: This is a cross-sectional retrospective descriptive analytical study based on a review of the medical records of 16 patients who underwent arterialization of the dorsal venous arch of the foot for limb salvage from January 2016 to January 2021. Results: Four (25%) of the 16 patients who underwent arterialization of the venous arch of the foot underwent a major amputation during the same hospital stay and one patient (6.25%) had a major amputation within 6 months. The other 11 patients (68.75%) had their limbs preserved, with 10 undergoing minor amputations (toes and forefoot) and one patient having no additional procedures. Conclusions: We conclude that the technique of arterialization of the dorsal venous arch of the foot should be considered in selected cases. It is a valid alternative for limb salvage when conventional treatment is impossible.

Arterialização venosa superficial com veia safena magna in situ: a experiência de um único centro / Superficial venous arterialization with the great saphenous vein in situ: a single-center experience

Resumo Contexto A arterialização do arco venoso dorsal do pé é uma técnica indicada em casos de isquemia crítica de membros inferiores sem leito distal adequado que possibilite tratamento convencional, como revascularização, angioplastia ou tratamento clínico. Objetivos O propósito do trabalho foi apresentar o resultado da arterialização do arco venoso do pé em 16 pacientes submetidos a essa técnica. Métodos Tratou-se de um estudo analítico descritivo retrospectivo transversal, baseado na revisão de prontuários de 16 pacientes submetidos à arterialização do arco venoso dorsal do pé para salvamento de membro, entre janeiro de 2016 a janeiro de 2021. Resultados Dos 16 pacientes submetidos à arterialização do arco venoso do pé, 25% (4) evoluíram para amputação maior durante a mesma internação, e 6,25% (1) pacientes evoluíram para amputação maior após 6 meses. Os demais pacientes (68,75%, 11) tiveram seus membros preservados, sendo que 10 foram submetidos a amputações menores (pododáctilos e antepé), e 1 paciente não necessitou de procedimento adicional. Conclusões A técnica de arterialização do arco venoso dorsal do pé deve ser considerada em casos selecionados. Trata-se de uma alternativa válida para a preservação do membro na impossibilidade de tratamento convencional.

Sonographic diagnosis of clinically unsuspected thrombosis of the medial marginal vein and dorsal arch of the foot.

Foot pain is common in daily clinical practice but thrombosis of the foot veins is rarely considered as a differential diagnosis. Several cases of plantar veins thrombosis are reported in literature but a detailed description of ultrasonographic findings in case of thrombosis of the dorsal venous arch of the foot is lacking. We report a case of ours with a thrombosis of the medial marginal vein and dorsal venous arch of the foot, showing its close anatomical relation with the extensor hallucis longus tendon.

A Patient with a Cavernous Sinus Dural Arteriovenous Fistula in Whom an Approach through the Jugular Venous Arch Involving Facial Vein Return Was Adopted.

Objective: We report the case of a cavernous sinus dural arteriovenous fistula (CSdAVF) treated by transvenous embolization (TVE) via the jugular venous arch (JVA) connecting bilateral superficial cervical veins. Case Presentation: A male patient in his 50s presenting with diplopia and headache was diagnosed with a CSdAVF. The first session of TVE resulted in incomplete obliteration of the fistula due to poor accessibility through the inferior petrosal sinus (IPS), and postoperative computed tomography angiography (CTA) disclosed a newly developed drainage route into the facial vein (FV) connecting to the anterior jugular vein (AJV) and the JVA. The patient underwent the second session of TVE through the JVA, FV, and the superior ophthalmic vein (SOV), and obliteration was achieved. Conclusion: There is a considerable variation in the anatomy of facio-cervical veins in patients with CSdAVF. Meticulous preoperative evaluation of the venous drainage route using modern diagnostic tools is indispensable to achieve successful results in patients with CSdAVF.

Descripción anatómica del arco venoso dorsal de la mano en una muestra de población de Bucaramanga, Colombia / Anatomical description of the dorsal venous arch of the hand in a population sample of Bucaramanga, Colombia

Se estudió el arco venoso dorsal de la mano (AVD) en una muestra de la población de Bucaramanga en 54 mujeres y 50 hombres. Las variables estudiadas en el AVD fueron: número de venas que lo forman, número de venas que recorren su interior, presencia de una vena que forme su parte lateral y medial, conformación cerrada o discontinua del AVD, si la vena metacarpiana del primer dedo se unía al AVD y contribuía a la formación de la vena cefálica, si la vena metacarpiana del quinto dedo se unía al AVD y contribuía a la formación de la vena basílica. También se revisó la concordancia entre la vena que escogían dos observadores independientes, como la más adecuada para venopunción. La comparación con los textos clásicos de anatomía evidenció concordancia en que cerca de la cabeza de los metacarpianos se forman venas metacarpianas dorsales, pero, no siempre estas venas se unen de forma completa para formar un "arco venoso cerrado" como lo describen los esquemas de la mayoría de los autores. Sólo un 41,8 % fueron AVD cerrados. Las venas metacarpianas del primer y del quinto dedo se unieron al AVD en un 44,23 % y un 89,42 % respectivamente. Este dato, sumado al hecho de que en el primer y quinto dedos pueden existir más de una vena que drene su sangre, las cuales no siempre se unen al AVD, ayudan a explicar la razón de porqué en otros estudios se describe ausencia de venas cefálica o basílica o presencia de varias venas cefálicas que permiten la formación de ciertos patrones de la fosa cubital. Se encontró concordancia del 78,85 % en cuanto a la vena escogida para posible venopunción y en el análisis bivariado, hubo asociación estadística de esta concordancia al cruzarla con el número de venas que recorren el interior del AVD.

The dorsal venous arch of the hand (AVD) was studied in a sample of the Bucaramanga population of 54 women and 50 men. The variables studied in the AVD were: Number of veins that form it, number of veins that run through its interior, presence of a vein that forms its lateral and medial part, closed or discontinuous conformation of the AVD, if the metacarpal vein of the first finger joined the AVD and contributed to the formation of the cephalic vein, if the metacarpal vein of the fifth finger joined the ADL and contributed to the formation of the basilic vein. The concordance between the vein chosen by two independent observers was also reviewed, as the most suitable for venipuncture. The comparison with the classic anatomy texts showed concordance in which dorsal metacarpal veins are formed near the metacarpal head, but these veins do not always unite completely to form a "closed venous arch" as described in metacarpal diagrams by most authors. Only 41.8 % were closed AVD. The metacarpal veins of the first and fifth toes joined the AVD in 44.23 % and 89.42 % respectively. This fact, in addition that in the first and fifth fingers, there may be more than one vein draining the blood, which do not always bind to the AVD, helps explain the reason other studies describe absence of cephalic veins, basilica or presence of several cephalic veins that allow the formation of certain patterns of the cubital fossa. There was 78.85 % agreement regarding the vein chosen for possible venipuncture and in the bivariate analysis, there was a statistical association of this concordance when crossing it with the number of veins that run through the interior of the AVD.

Variaciones anatómicas en el drenaje venoso del cuello / Anatomical variations in the venous drainage of the neck

Resumen Las venas superficiales, especialmente la vena yugular externa, son cada vez más utilizadas para canalización o procedimientos diagnósticos, terapias intravenosas, nutrición parenteral en pacientes debilitados. Las variaciones en el drenaje venoso de la cabeza y cuello son importantes no solamente para los anatomistas y radiólogos, sino también para los cirujanos. Durante una disección de rutina en el Laboratorio de Morfología de la Universidad de Pamplona en un cadáver masculino de 75 años de edad, se encontraron variaciones anatómicas e inusuales patrones de drenaje en la región de cara y cuello, las cuales fueron cuidadosamente disecadas y los detalles morfológicos fueron fotografiados; esas variaciones consistían en: ausencia unilateral de vena yugular externa. La vena lingual, la vena infrahioidea y la vena tiroidea superior tenían conexiones venosas transversas que drenaban en un arco venoso localizado entre la arteria carótida común y la arteria tiroidea superior. Este arco venoso drenaba hacia arriba en la vena facial común y hacia abajo en la vena yugular interna. El conocimiento de las variaciones anatómicas y morfológicas en las venas de cabeza y cuello es esencial para llevar a cabo procedimientos quirúrgicos exitosos en estas regiones.

Abstract The superficial veins, especially the external jugular vein are increasingly used for cannulation or diagnostic procedures, intravenous therapy, parenteral nutrition in debilitated patients. Variations in the venous drainage of the head and neck are important not only for anatomists and radiologists but also for surgeons. During routine dissection in the Laboratory of Morphology, University of Pamplona in a 75 year-old male cadaver in the region face and neck anatomical variations and unusual drainage patterns were found, which were dissected carefully and morphological details were photographed; these variations consisted of unilateral absence of external jugular vein. The lingual vein, the infrahyoid vein and the superior thyroid vein had transverse venous connections that drained into a venous arch located between the common carotid artery and the superior thyroid artery. This draining venous arch upward in the common facial vein and down into the internal jugular vein. Knowledge of the anatomical and morphological variations in the veins of the head and neck is essential to carry out successful surgical procedures in these regions.

Malposition of central venous catheter in the jugular venous arch via external jugular vein -a case report.

The central venous cannulation is commonly performed in the operating rooms and intensive care units for various purposes. Although the central venous catheter (CVC) is used in many ways, the malpositioning of the CVC is often associated with serious complications. We report a case of an unexpected malposition of a CVC in the jugular venous arch via external jugular vein.

Palmar arch reconstruction using dorsal venous arch of foot for revascularisation of multiple digits.

A case of trauma causing total loss of superficial and deep palmar arches of hand with ischemia of all the digits was managed using dorsal venous arch of the foot to reconstruct the palmar arch. The ends of the venous arch were anastomosed to radial and ulnar arteries and the tributaries to the arch were coapted to the cut ends of the common digital vessels and princeps pollicis. The surgery yielded gratifying results, successfully revascularising all the digits.
