Our studies were carried out on 8 male and 2 female baboons Papio anubis cadavers. We examined a total of 20 hind legs. The vessels of the hind leg were filled with coloured latex. Afterwards we prepared the superficial and deep veins and accompanying arteries. We paid attention to the location, diameter and the course of the long and short saphenous veins. We found many differences between the system of superficial veins in the baboon hind leg and that in the human lower limb. First of all, the long saphenous vein in the baboon Papio anubis presented as two similar trunks that ran together with a concomitant artery. The saphenofemoral junction was also duplicated. The distance between these outlets was about 4 mm and their location was different from that in humans. Neither trunk exceeded 2.5 m in diameter. Some human-like features were noticed in the system of the short saphenous vein in Papio anubis. The diameter of the short saphenous vein and its course and the location of the saphenopopliteal junction were very similar to those in humans. On the other hand, the short saphenous vein was the main superficial venous channel of the hind limb of Papio anubis.

Although the baboon is considered a good animal model in biomedical research, no description of the superficial veins of the foot in Papio anubis is found in the available literature. The current study was conducted to document the anatomy of these veins in the baboon foot. A macroscopic anatomical investigation was carried out on 20 hind legs (10 cadavers) of the adult Papio anubis (9 males and 1 female). The circulatory system of the entire body was filled with coloured latex. Traditional methods were used for the preparation of the veins of the legs. These were then compared with the venous system of the lower extremities in humans as presented in the literature. The medial and lateral metatarsal veins, the dorsal venous network, the long saphenous vein and the short saphenous vein in Papio anubis were described according to their origin, course, opening, length and diameter. The network observed was divided into three types with respect to the connections between the superficial veins. The investigation revealed no symmetry in the venous system of the baboon foot. The short saphenous vein appeared to be the main vein of the hind leg in Papio anubis and the long saphenous vein ran as a double vessel.

Chronic vein insufficiency (CVI) is a disease which, when it develops, leads to varicose veins of the lower limbs. As approximately 25% to 50% of people suffer from it, it should be recognised as a public disease. The treatment of chronic vein insufficiency is based on a surgical approach. The aim of the operation is to remove (strip) the insufficient major saphenous vein (MSV), the main cause of the disease. The major saphenous vein drains into the femoral vein and forms the sapheno-femoral junction, which is located in the hiatus saphenous within the femoral triangle. We conducted 94 varicose vein operations by the Babcock method on patients suffering from chronic vein insufficiency. This surgical treatment was performed in “Therapy”, a private clinic for peripheral vessel disease. We operated on 52 left lower limbs and 42 right lower limbs. The patients were qualified for the operation procedure after physical examination and Doppler ultrasonography imaging. We identified 5 types of major saphenous vein tributary drainage. The most common was Type I, in which there were 3 tributaries draining directly into the major saphenous vein. This type consisted of 45 cases (47.87%). We distinguished here 3 modifications. In Type II, however, there were 4 direct tributaries that drained into the major saphenous vein in 23 cases (24.46%). In this group of patients also 3 modifications were distinguished. Type III occurred in 14 cases (14.89%). We identified here 2 direct tributaries that drained into the saphenous vein and divided this type into 2 modifications. Type IV occurred in 8 cases (8.51%). Here we found 5 or 6 direct tributaries depending on the number of the external pudendal veins. Type V turned out to be very rare, occurring in only 4 cases (4.25%). Among all the types mentioned a thin tributary 1–2 mm wide was found in 10 cases (10.63%). This ran from under the fascia cribrosa into the saphenofemoral junction in the hiatus saphenous. This may be one of the causes of the recurrences of chronic vein insufficiency. There is also the possibility that a tributary will be overlooked or ignored during the operation, particularly when Type IV appears with 5 or 6 direct collaterals.

The shape of the middle lobe of the right lung may vary greatly because of the varying extent of its surfaces in different specimens and the profuse branching of the two segmental bronchi, arteries and veins. The architecture of the middle lobe is therefore especially difficult to understand. For these reasons, attention must be paid to the arrangements of the veins which separate its segments. Thus, the aim of this study was to investigate the ways in which venous drainage of the middle lobe segments may take place. The studies were performed on 40 organs taken from adult human cadavers of both sexes. The pulmonary vessels and bronchi were filled with Plastogen G, after which corrosion casts were made and skeletonised. The lateral segment (SIV) and the medial segment (SV) of the middle lobe were drained in 55% of specimens by one vein and in 35% of specimens by two separately terminated veins. Considerably less frequently there were 3 veins (7.5% of specimens) and only in 2.5% of specimens — 4 veins. In specimens where the middle lobe was drained by one vein (55%) it was formed by joining the lateral (V4) and the medial (V5) segmental veins. In 32.5% of specimens these two segmental veins were formed by a junction of their typical sub-segmental tributaries, where the posterior sub-segmental vein V4a and the superior sub-segmental vein V5a were intra-segmental veins, whereas the anterior sub-segmental vein V4b and the inferior sub-segmental vein V5b were inter-segmental veins. In the remaining 22.5% of specimens with one vein of the middle lobe we noticed modifications in the course of the bronchi, arteries and veins. In the middle lobes drained by two separate veins (35% of specimens) there were independently running segmental veins, V4 and V5. These were formed by their typical tributaries (15%), whereas in the remaining 20% of specimens there were unusual patterns. Three individual veins of the middle lobe (7.5% of specimens) accompanied the lateral-medial type of bronchial arrangement in 5% of specimens, while in 2.5% of specimens the bronchial pattern was of the superior-inferior type. These veins run so as to form more often two superior and one inferior vein. The venous pattern of the middle lobe was consistent with the bronchial and arterial patterns in 35% of specimens. However, this conformation was present in those organs (32.5% of specimens) where the middle lobe was drained by one vein and only in 2.5% of specimens if there were two veins. If 3 or 4 individually emptied veins were present, we could not find any organ in which the bronchial, arterial and venous pattern would be fully compatible. Thus, the research revealed that convenient conditions for the separation of the segments of the middle lobe of the right lung were present in approximately 1/3 of the middle lobes.

This paper is a detailed case study of the persistent anastomotic channel between the cephalic vein and the external jugular vein, running anterior to the clavicle, corresponding to the jugulocephalic vein present at early stages of the ontogenesis in humans. This connection is not only a relic of early foetal development seldom occurring in adults, but it may also be of clinical significance, increasing the risk of complications during the cephalic vein catheterisation, clavicular fractures or head and neck surgery. The novelty in this paper was to determine the presence and distribution of valves within the persistent jugulocephalic vein. Three bicuspid venous valves were found that allowed the blood to flow only in one direction — from the cephalic vein to the external jugular vein. The anastomosis between the persistent jugulocephalic vein and the thoracoacromial veins was additionally present. Due to lack of similar data in the literature, further research should be performed on the presence and distribution of the venous valves in various types of the persistent jugulocephalic vein in humans.

The plantaris muscle usually begins with a short and small muscle belly on the popliteal surface of the femur and on the knee joint capsule. It continues distally to form a long and thin tendon typically fixed to the calcaneal tuberosity. However, the course and the insertion of the plantaris muscle is variable, which may influence the development of Achilles tendinopathy. The plantaris tendon may also be used for reconstruction of tendons and ligaments, such as talofibular and calcaneofibular ligament. In literature review no data concerning the co-occurrence of anatomic variations of the plantaris muscle tendon in different individuals has been found. This report presents a rare variant of the plantaris muscle insertion into the deep crural fascia on the left leg and absence of the plantaris muscle on the right leg of the same individual.
