Iatrogenic Isolated Ruptured Dorsalis Pedis Artery Pseudo Aneurysm : A Rare Case Report

A Dorsalis Pedis Artery (DPA) pseudo aneurysm is one of the most uncommon peripheral arterial aneurysms. These aneurysms can cause distal embolization and thrombosis, leading to limb loss. However, their rupture is unusual1. Any type of injury or perhaps an iatrogenic intervention can cause a pseudo localized swelling of the dorsalis pedis artery, which is a relatively unusual condition. Whenever it presents as a non-pulsatile soft tissue mass in the presence or absence of a specific predeceasing event, it can lead to a difficult diagnostic dilemma2. The rare instance of an iatrogenic pseudo aneurysm of the dorsalis pedis artery which mimicked cellulitis of the right foot is discussed in this case report. Coil embolization of the proximal artery, and the aneurysm was successfully done by the intervention radiologist. After the procedure, collateral circulation was maintained. No ischemic symptoms such as intermittent claudication or pain at rest were observed. This approach may be useful in treating similar cases

Anatomical variations of the dorsalis pedis artery in a Thai population / Variaciones anatómicas de la arteria dorsal del pie en una población tailandesa

SUMMARY: The dorsalis pedis artery (DPA) is a vital artery that supplies the foot and ankle area which is clinically important for palpating when taking the pulse. This research was performed on fresh cadaveric dissection of 40 legs by injecting paint into popliteal artery for tracking the dorsalis pedis artery and its branches. The present research revealed that the Thai population has an anatomical variation and different location of the DPA and exact location of DPA for estimating the location of the DPA and may have clinical implications. The statistically descriptive analysis elucidated the distances of the DPA to the lateral malleolus and medial malleolus which were 51.48 ± 7.27 mm and 42.62 ± 11.40 mm, respectively. The distance of the extensor hallucis longus (EHL) to the DPA was 14.29 ± 4.11 mm. The length of the dorsalis pedis artery which measured from artery on intermalleolar line to its dipping in 1st intermetatarsal space to be 122.03 ± 21.07 mm. The arcuate loop which is anastomosis U-loop of lateral tarsal arteries of the DPA was found 55 % in Thais population. There were no statistically significant differences of all parameters between the side and sex in DPA consideration. An understanding of the variations of the anatomical vasculature of DPA is essential for precise clinical assessment because exact anatomical knowledge and location can contribute to the pulse taking and be applied in surgical procedure.

RESUMEN: La arteria dorsal del pie (ADP) es una arteria vital que irriga eldorso del pie y el tobillo, y es clínicamente importante para la toma del pulso. Esta investigación se realizó en disección cadavérica de 40 piernas inyectando látex coloreado en la arteria poplítea para rastrear la ADP y sus ramas. La presente investigación reveló que en la población tailandesa la ADP tiene una variación anatómica y una ubicación diferente. Por tanto, determinar la ubicación exacta del ADP será útil para las implicaciones clínicas. El análisis estadísticamente descriptivo determinó que las distancias del ADP al maléolo lateral y al maléolo medial eran 51,48 ± 7,27 mm y 42,62 ± 11,40 mm, respectivamente. La distancia del tendón del músculo extensor largo del halux (ELH) al ADP era de 14,29 ± 4,11 mm. La longitud de la ADP, desde la línea intermaleolar hasta su entrada al primer espacio intermetatarsiano, era de 122,03 ± 21,07 mm. El asa arqueada, que es una anastomosis U-loop de las arterias tarsales laterales de la ADP, se encontró en un 55 % de la población tailandesa. No hubo diferencias estadísticamente significativas en todos los parámetros de la ADP entre el lado y el sexo. La comprensión de las variaciones de la variaciones anatómicas de la ADP es esencial para una evaluación clínica precisa. El conocimiento anatómico exacto y la ubicación pueden contribuir a la toma del pulso y ser útil en el procedimiento quirúrgico.

Pseudoaneurysm of Dorsalis Pedis Artery Following Lisfranc Surgery: A Rare Complication

@#Aneurysm and pseudoaneurysm of the dorsalis pedis artery remains to be rare vascular entities with a reported incidence of 0.5% of peripheral arterial aneurysms. Only, few cases were reported. The formation of pseudoaneurysm is commonly associated with fracture, laceration wound or iatrogenic arterial injury. An arterial injury that coincides with pseudoaneurysm can initially be missed due to lack of clinical findings. Prompt recognition remains paramount to reduce morbidity and mortality. Here, we present a rare complication of a commonly performed orthopaedic procedure in a young male who presented with painful swelling over left foot after he was involved in an industrial injury. He presented again with a pulsating mass over his left foot after 2 months post fixation surgery of a Lisfranc injury. He was treated conservatively with compression bandage and able to regain to his normal activity after the treatment initiated.

Anatomy of the dorsalis pedis artery / Anatomía de la arteria dorsal del pie

The dorsalis pedis artery (DPA) is the largest blood vessel distal to the ankle joint. It is the continuation of the anterior tibial artery (ATA) and runs along the dorsum of the foot until the 1st intermetatarsal space. The DPA gives rise to five branches, viz. medial tarsal, lateral tarsal, arcuate, deep plantar and dorsal metatarsal arteries. Given the vast blood supply provided by the DPA, in the current era of microvascular surgery, the anatomy of the DPA is of increasing interest to anatomists, surgeons and angiographers. The aim of this study was to outline the course, origin, branching patterns and possible variations of the DPA. The present study included the dissection of forty (n=40) cadaveric specimens of the lower limb region (Left: 25; Right: 15). The origin, course and branching patterns of the artery were studied. These morphological parameters were further analysed with regard to laterality to determine if a correlation existed. The Pearson Chi-square test was employed and a p value of less than 0.05 was deemed statistically significant. Although the DPA was present in 97.5 % of cases, it followed the standard anatomical description in only 42.5 % of cases. The DPA originated from the peroneal artery in 5 % of cases. In 25 % of cases, DPA deviated laterally. Variation in the branching pattern of the DPA, which was recorded in 50 % of cases, was further classified according Types 1 to 6. The findings of this study correlated closely with most previous studies. However, the incidence of lateral deviation of the DPA was higher in this study as well as the incidence of Type 1 variation in branching pattern. Additionally, this study proposes a novel variation in branching pattern which has been termed Type 6, which displays a recurrent branch of the Type 5 variation. The DPA has an important role in a clinical setting since the DPA flap is employed in reconstructive surgeries and peripheral circulation may be assessed by the palpation of the DPA pulse. Therefore, a thorough understanding of the anatomy of the DPA is of prime importance to podiatrists, surgeons, anatomists and angiographers.

La arteria dorsal del pie (ADP) es el vaso sanguíneo más grande distal a la articulación del tobillo. Es la continuación de la arteria tibial anterior (ATA) y se extiende a lo largo del dorso del pie hasta el primer espacio metatarsiano. La ADP da lugar a cinco ramas: a. tarsalis medialis, a. tarsalis lateralis, a. arcuata, a. plantaris profunda y aa. metatarsales dorsales. Dado el vasto suministro de sangre proporcionado por la ADP, en la era actual de la cirugía microvascular, la anatomía de la ADP es de creciente interés para los anatomistas, cirujanos y expertos en angiografía. El objetivo de este estudio fue delinear el curso, origen, patrones de ramificación y las posibles variaciones de la ADP. El presente estudio incluyó la disección de cuarenta (n = 40) muestras cadavéricas del miembro inferior (izquierda: 25; derecha: 15). Se estudiaron los patrones de origen, curso y ramificación de la arteria. Estos parámetros morfológicos se analizaron adicionalmente con respecto a la lateralidad para determinar si existía una correlación. Se empleó la prueba Chi-cuadrado de Pearson y se consideró estadísticamente significativo un valor de p de menos de 0,05. Aunque la ADP estuvo presente en el 97,5 % de los casos, siguió la descripción anatómica estándar en solo el 42,5 % de los casos. La ADP se originó en la arteria fibular en el 5 % de los casos. En el 25 % de los casos, la ADP se desvió lateralmente. La variación en el patrón de ramificación de la ADP, que se registró en el 50 % de los casos, se clasificó según los tipos 1 a 6. Los hallazgos de este estudio se correlacionaron estrechamente con la mayoría de los estudios previos. Sin embargo, la incidencia de desviación lateral de la ADP fue mayor en este estudio, así como la incidencia de la variación del tipo 1 en el patrón de ramificación. Además, este estudio propone una nueva variación en el patrón de ramificación que se ha denominado Tipo 6, que muestra una rama recurrente de la variación Tipo 5. La ADP tiene un papel importante en la clínica, ya que el colgajo de la ADP se emplea en cirugías reconstructivas y la circulación periférica se puede evaluar mediante la palpación del pulso de la ADP. Por lo tanto, una comprensión profunda de la anatomía de la ADP es de vital importancia para los podólogos, cirujanos, anatomistas y en la angiografía.

Unusual Pseudoaneurysm of the Dorsalis Pedis Artery after an Iatrogenic Injury

Aneurysm and pseudoaneurysm of the dorsalis pedis artery (DPA) are rare vascular entities. Pseudoaneurysms of the DPA are commonly due to blunt trauma, sharp penetrating injury, fracture, or iatrogenic injury. Herein, we report the case of a patient with a rare iatrogenic pseudoaneurysm that occurred after blood sampling. The diagnosis was suspected based on palpitation of a pulsatile mass on the dorsal foot and confirmed by color Doppler ultrasound and computed tomography angiography. Surgical treatment was successfully performed by reconstruction with an autologous venous graft. The patient recovered well, with no ischemic complications.

A segmental hypoplastic anterior tibial artery coexisting with a hypertrophied perforating fibular artery a case report and clinical implications / Coexistencia de una arteria tibial anterior hipoplásica segmentaria con una arteria fibular perforante hipertrofiada. Reporte de caso e implicancias clínicas

Vascular injuries of the lower limb, especially from penetrating gunshot wounds, and peripheral arterial diseases are on the increase and management of these and many other lower limb injuries involve increasing usage of vascular interventions like by-pass surgery, per-cutaneous transluminal angioplasty, arterial cannulation, arterial bypass graft or minimally invasive measures like percutaneous trans-arterial catheterization, among others. A thorough knowledge of infrapopliteal branching most especially their pathways and luminal diameters are important to surgeons in selecting appropriate surgical interventions or procedures. We report the case in which one of the 3 terminal branches of the popliteal artery (PPA), the anterior tibial artery (ATA) of good caliber size at origin became hypoplastic in the anterior leg region after giving off numerous muscular branches. Continuing as an almost attenuated dorsalis pedis artery (aDPA) in the dorsum of the foot, the latter was reinforced by an enlarged hypertrophied fibular artery. This case illustrates yet the importance of the fibular artery as the dominant of the 3 infrapopliteal branching arteries, reinforcing or replacing the posterior tibial artery (PTA) when it is weak or absent by a strong communicating branch or, reinforcing a weak ATA and dorsalis pedis artery (DPA) by a strong perforating fibular artery as being reported. The PTA however travelled a normal course yielding the medial and lateral plantar arteries posterior to the abductor hallucis muscle. This case demonstrates the importance of collateral communications and reinforcements from other infrapopliteal arteries, whenever one of its members or subsequent branches are absent or hypoplastic. A very sound knowledge of the various branching patterns of the PPA can be gained via pre-operatively vascular angiography, designed to guide the surgeon in the selection of appropriate surgical interventions, adding value to patients care in helping to reduce iatrogenic surgical vascular complications and reduction in total number of limb loss.

Las lesiones vasculares de los miembros inferiores, especialmente las heridas penetrantes por arma de fuego y enfermedades arteriales periféricas, están en aumento. Su manejo, así como el de otras lesiones en los miembros inferiores, implican un mayor uso de intervenciones vasculares como la cirugía de by-pass, angioplastía transluminal percutánea, canulación arterial, injerto de derivación arterial o medidas mínimamente invasivas como el cateterismo transarterial percutáneo, entre otros. El conocimiento profundo de las ramificaciones infrapoplíteas, muy especialmente sus vías y diámetros luminales son importantes para los cirujanos en la selección de las intervenciones o procedimientos quirúrgicos apropiados. Presentamos un caso en el cual, una de las 3 ramas terminales de la arteria poplítea (APP), la arteria tibial anterior (ATA), de buen calibre en su origen se hizo hipoplásica en la región anterior de la pierna después de un desprendimiento de numerosas ramas musculares. Continuó como una arteria dorsal del pie (ADP) casi atenuada en el dorso del pie; esta última se vio reforzada por una amplia arteria fibular hipertrofiada. Este caso ilustra la importancia de la arteria fibular como dominante de las 3 ramificaciones de las arterias infrapoplíteas, un refuerzo o sustitución de la arteria tibial posterior (ATP) cuando es débil o está ausente, por una fuerte rama comunicante, o bien refuerzo de una débil ATA y ADP por una fuerte arteria fibular perforante como en el caso reportado. La ATP sin embargo tenía un trayecto con un curso normal generando las arterias plantares medial y lateral, posterior al músculo abductor del hállux. Este caso demuestra la importancia de las comunicaciones colaterales y refuerzos de otras arterias infrapoplíteas, cada vez que uno de sus componentes o ramas posteriores están ausentes o hipoplásicas. Un conocimiento detallado de los diferentes patrones de ramificación de la APP puede ser adquirido a través de una angiografía vascular previo a la cirugía, diseñada para guiar al cirujano en la selección de las intervenciones quirúrgicas adecuadas, agrega valor a la atención de los pacientes, ayuda a disminuir las complicaciones vasculares quirúrgicas iatrogénicas y reduce el número total de pérdidas de miembros inferiores.

Effect of arterial blood collection from different spots in infants / 现代临床护理

ObjectiveTo investigate effects of the arterial blood collection from radial artery,brachial artery,femoral artery and orsalis pedis artery for gas analysis of infants.Methods Three hundred and fifty two infants receiving blood collection were divided into four groups radial artery (n=92),brachial artery (n=94),femoral artery (n=73) and dorsal artery (n=53).Comparisons were done between them in terms of one-time success rate of puncturing and rate of complications from puncturing.Result The radial artery group had lowest rates of hematoma and mistaken puncturing into veins (P<0.05) and higher rate of one-time successful puncturing (P<0.001).Conclusion The radial artery is the first choice for infants undergoing arterial puncturing.

An Anatomical study on Dorsalis Pedis Artery.

Background:The study of Dorsalis pedis artery and variations in its branching pattern has been reported sporadically. The purpose of this study was to evaluate the arterial supply on the dorsum of the foot. Materials and Methods: The study was carried out on forty two dissected limbs of unknown sex and age from the department of Anatomy,BMCRI,Bangalore. Results and Discussion:The incidence of classical text book description was found to be very less in the present study. In 16.67% of cases the arcuate artery was completely absent, which was compensated by two large lateral tarsal arteries that provided the dorsal metatarsal arteries. In 9.52% of cases the dorsalis pedis artery was absent. Conclusion:The findings suggest that the lateral aspect of the dorsum of the foot has a poor nourishment.

Hypoplastic anterior tibial artery associated with continuation of fibular (peroneal) artery as dorsalis pedis artery: a case report / Arteria tibial anterior hipoplásica asociada con la continuación de la arteria fibular como arteria dorsal del pié: un reporte de caso

Arterial variations of distal parts of lower limb are well documented. However, continuation of fibular artery as dorsalis pedis artery is a rare finding. Unusual course and distribution of the anterior tibial artery and fibular artery were observed during routine anatomical dissection of the right lower limb of an approximately 40-year-old male cadaver. The arteries of the crural region arose from the popliteal artery, as usual. However the anterior tibial artery was hypoplastic. The fibular artery was larger than usual and crossed the lowest portion of the interosseous membrane and continued as dorsalis pedis artery. Posterior tibial artery had a normal course and distally divided into medial and lateral plantar arteries. The awareness of these variations is important to vascular surgeons while performing arterial reconstructions in femorodistal bypass graft procedures, and also to orthopaedic surgeons during surgical clubfoot release.

Las variaciones arteriales de las partes distales de los miembros inferiores están bien documentados. Sin embargo, la continuación de la arteria fibular como arteria dorsal del pie es un hallazgo raro. El curso y distribución inusual de la arteria tibial anterior y la arteria fibular se observaron durante la disección anatómica de rutina en el miembro inferior derecho del cadáver de un hombre de aproximadamente 40 años de edad. Las arterias de la región crural se originaron desde la arteria poplítea como es usual. Sin embargo, la arteria tibial anterior era hipoplásica. La arteria fibular era más grande de lo habitual, cruzó la porción más baja de la membrana interósea y se mantuvo como la arteria dorsal del pie. La arteria tibial posterior tuvo un curso normal; distalmente se dividió en las arterias plantares medial y lateral. El conocimiento de estas variaciones es importante para los cirujanos vasculares al realizar reconstrucciones arteriales en procedimientos de injerto de bypass femorodistal, y también para los cirujanos ortopédicos durante la liberación quirúrgica del pie zambo.

Study for the discrepancy of arterial blood pressure in accordance with method, age, body part of measurement during general anesthesia using sevoflurane / 대한마취과학회지

BACKGROUND: Many pieces of previous research on measuring blood pressure (BP) using different methods focused on the disparity in the results. However, none of them dealt with the disparity caused by the difference in age and inhalation anesthetics. We attempted to find the variance in accordance with age, body part, and measuring methods (invasive vs noninvasive) and also studied how sevoflurane influences BP as the operation progresses. METHODS: In sixty patients, we measured the arterial BP in the upper and lower limbs by noninvasive methods before inducing anesthesia. After induction, we used sevoflurane to maintain anesthesia, and injected catheters into the radial artery and dorsalis pedis artery to measure arterial pressure at every ten minute by both invasive and noninvasive methods. RESULTS: The patients who were 40 or older showed significantly higher values in the systolic BP than the patients younger than 40. The values of systolic and diastolic BP measured by a noninvasive oscillometric method were meaningfully higher than those measured by an invasive method. As the operations progressed, the lower limbs showed higher systolic pressure than the upper limbs regardless of measuring methods, whereas the opposite is true for diastolic pressure. CONCLUSIONS: The values in the arterial BP were measured high by noninvasive method. Systolic BP were estimated significantly high in the older patients and in the lower leg. Due to the effect of sevoflurane, the diastolic BP in the lower limbs becomes lower than that of upper limbs regardless of measuring methods, as the operation progresses.

Anatomical review of dorsalis pedis artery flap for the oral cavity reconstruction

The dorsalis pedis artery (DPA) was renamed from the anterior tibialis artery after it passed under the extensor retinaculum, and DPA travels between the extensor hallucis longus and extensor digitorum longus muscle along the dorsum of the foot. After giving off the proximal and distal tarsal, arcuate and medial tarsal branches, DPA enters the proximal first intermetatarsal space via the first dorsal metatarsal artery (FDMA), which courses over the first dorsal interosseous muscle (FDIM). For detailed knowledge of the neurovascular anatomy of a dorsalis pedis artery flap (DPAF) as a routine reconstructive procedure after the resection of oral malignant tumors, the precise neurovascular anatomy of DPAF must be studied along the DPA courses as above. In this first review article in the Korean language, the anatomical basis of DPAF is summarized and discussed after a delicate investigation of more than 35 recent articles and atlas textbooks. Many advantages of DPAF, such as a consistent flap vascular anatomy, acceptable donor site morbidity, and the ability to perform simultaneous flap harvest using oral cancer ablation procedures, and additional important risks with the pitfalls of DPAF were emphasized. This article will be helpful, particularly for young doctors during the special curriculum periods for the Korean National Board of Specialists in the field of oral and maxillofacial surgery, plastic surgery, otolaryngology, orthopedic surgery, etc.

Foot Necrosis Following Percutaneous Cannulation of the Dorsalis Pedis Artery: A Case Report / 대한구급학회지

Arterial canuulation is generally used to monitor blood pressure and sample blood for gas analysis. Radial and dorsalis pedis arteries are commonly used for arterial cannulation. It is a simple, safe, and uncomplicated procedure, but some complications have been reported, including bleeding, hematoma, infection, pseudoaneurysm, and thromboembolism. Although thromboembolism is not common, it could be serious because it can lead to digital ischemia and necrosis. We present a case of foot necrosis following dorsalis pedis artery cannulation in a 65-year-old patient who underwent small bowel resection.

Morphological Study on the Dorsalis Pedis and First Dorsal Metatarsal Arteries in Koreans / 대한해부학회지

Morphological variation of the dorsalis pedis and the first dorsal metatarsal arteries are important because these arteries are used as flap pedicles during surgery of hands and feet with tissue defects. The purpose of this study was to investigate variations in the running pattern of the dorsalis pedis and first dorsal metatarsal arteries. We investigated the dorsalis pedis artery in 92 adult cadaver feet and 50 first dorsal metatarsal arteries that arose from these dorsalis pedis arteries were studied. The dorsalis pedis artery was classified into six types according to its running direction. The dorsalis pedis artery running in the direction of the first intermetatarsal space and branching into the first dorsal metatarsal artery was observed in 79.3%. The dorsalis pedis artery coursing laterally and becoming the first dorsal metatarsal artery after changing its direction medially was seen in 5.4%. The dorsalis pedis artery was thin and did not connect to the first dorsal metataral artery, split in the region of ankle and came to an end, and ran laterally and did not connect to the first dorsal metatarsal artery in 8.7%, 2.2%, and 3.7%, respectively. The dorsalis pedis artery ran superficial to the deep fascia in 1 of the 92 specimens (1.1%). The first dorsal metatarsal artery was classified into three types according to the positional relationship between the first dorsal metatarsal artery and the first dorsal interosseous muscle. The first dorsal metatarsal artery ran above or into the first dorsal interosseous muscle in 72% and ran below the first dorsal interosseous muscle in 22%. The first dorsal metatarsal artery that was either above or inside the first dorsal interosseous muscle but could not used as a flap pedicle because it was too small was seen in 6%.

A study on the relationship between ultrasonography of dorsalis pedis artery and hemorheology in patients with diabetic foot / 中华超声影像学杂志

Objective To study the relationship between ultrasonography of arteria dorsalis pedis and Hemorheology in patient with diabetic foot.Methods According to with or without frank anabrosis,51 patients were devided into two sub-groups:anabrosis group (23 patients) and no-anabrosis group (28 patients).The correlativity was analysed between the parameters of ultrasonography in arteria dorsalis pedis and hemorheological indices on patients with diabetic foot.Results When compared to patients without ulcers,vascular inner diameter (D),peak systolic velocity (PSV),resistent index (RI) and pulsatility index (PI) on patients with frank anabrosis were decreased significantly,but whole blood viscosity at high shear rate (BVH),whole blood viscosity at low shear rate (BVL),plasma viscosity (PV),fibrinogen (Fib) were increased.Multiple regression analyses indicated that the relationship between BVH,BVL and D was presence,partial regression coefficient (r) was -0.004 and -0.009 ; the relationship between PSV and BVH,PV was intimate,r was -0.957 and -25.655 ; the relationship between RI and BVH,PI and BVH,PV,Fib were relatively intimate,r was -0.009 , -0.141 , -2.666 , -0.383 ,respectively.Conclusions The changes of hemorheology can aggravate the abnormality of hemodynamics and the degree of vascular lesion in small vessels of lower limb,so it is one of influencing factor leading to lower limb arterial ischaemia and diabetic foot deterioration.
