Vein Injury

Objective: The injury to the common iliac vein (CIV) seems to be the most important concern during the anterior approach to the spine at L5–S1 level. We investigated the anatomy of the L5–S1 vertebral structures related to the CIV through a cadaveric study to find an anatomical clue for safe dissection of CIV.Methods: Ten cadavers were prepared for this study. After removing the peritoneum and the presacral fascia, the section from the lower part of the L5 to the upper part of the S1 vertebral body was removed with the CIV attached. After decalcification, 2 sections in the vertical and horizontal directions were made for histological study.Results: An adipose tissue layer was present between the intervertebral disc and CIV. The adipose tissue layer in 6 cadavers was thin, and in 3 of these cadavers, the CIV was attached to the vertebral body and the disc. In the other 4 cadavers, the CIV was clearly separated from the vertebral body and the disc by the intervening adipose tissue layer (IATL). Under the microscope, a thin layer surrounding the anterior longitudinal ligament, periosteum, and disc was observed, and we named this structure the ‘perivertebral membrane’. The perivertebral membrane was attached to the CIV when there was no IATL, but a potential space was detected under the membrane.Conclusion: There was a thin membrane, perivertebral membrane, between the CIV and L5–S1 disc. In cases with CIV adhesion to the disc due to the absence of IATL, the CIV may be mobilized indirectly through the perivertebral membrane.

Abstract The diameter at the origin of the internal iliac vein was found between 4.7 to 9.9 mm; for the right internal iliac vein between 4.7 to 9.7 mm; the statistical distribution groups value in ascending order being as follows: 4.7 to 5.5 mm: 4 cases (22.22% of cases); 6.9 to 7.8 mm: 6 cases (33.33% of cases); 8.4-8.8 mm: 4 cases (22.22% of cases); 9.1 to 9.7 mm: 4 cases (22.22% of cases). The diameter at the origin of the left internal iliac vein was between 4.8 to 9.9 mm, while the distribution statistics on groups of values, in ascending order, being as follows: 4.8-5.2 mm: 4 cases (22.22 % of cases); 6.8-7.1 mm: 8 cases (44.44% of cases); 8.3 to 9.9 mm: 6 cases (33.33% of cases). The diameter at the end of the internal iliac vein was between 5.9 to 10.2 mm; the diameter at the end of the right internal iliac vein was between 6.1 to 10.2 mm, the statistical distribution of values groups in ascending order being follows: 6.1 to 7.5 mm: 6 cases (33.33% of cases); 8.4 to 8.7 mm: 8 cases (44.44% of cases); 9.3 to 10.2 mm: 4 cases (22.22% of cases). The diameter at the end of the left internal iliac vein was between 5.9 to 9.9 mm, while the distribution statistics on groups of values in ascending order being as follows: 5.9 to 6.2 mm: 4 cases (22.22 % of cases); 7 to 7.6 mm: 3 cases (16.67% of cases); 8.3-8.4 mm: 5 cases (27.28% of cases); 9.1 to 9.9 mm: 6 cases (33.33% of cases). Comparing the common iliac vein caliber of the two, right and left, we found that in 10 cases (55.56% of cases), the right internal iliac vein has a greater diameter than the left one by 0.3 mm. In 8 cases (44.44% of cases), the left internal iliac vein has a larger diameter than the right one with 0.1-0.6 mm; between the two values there is a difference of 0.5 mm

Loop Snare

Caval filters are placed in the inferior vena cava (IVC) to prevent pulmonary thromboembolism in patients with deep vein thrombosis. If there is no indication for thrombo-embolic risk prevention, the filter can be removed to reduce potential filter-related complications. Advanced endovascular techniques are frequently used to retrieve IVC filters. We describe an alternative filter-removal technique for use when standard techniques are not practicable. In our method, the filter hook is embedded within the IVC wall. To retrieve it, a long introducer is inserted; a guidewire and the "loop snare" retrieval system are then advanced through it with a coaxial system and positioned below the filter at the level of the common iliac vein confluence. The guidewire is then passed through the loop, creating a "sling" around the filter which allows the application of traction from the bottom upwards, releasing the hook from the wall. The loop is then held under tension with the filter aligned in the IVC lumen, and the introducer is advanced distally to completely cover the filter, allowing complete retrieval of the filter without damaging the vessel walls. This modified Sling technique is a safe and feasible method for complicated IVC filter retrieval.

Abstract Introduction Communications between iliac veins in the pelvis are reported to be rare occurrences, which are mostly due to developmental abnormalities. The common iliac vein is formed by the joining of the internal and external iliac veins. Here, we present a detailed morphological and histological study of a rare communication found between the internal and external iliac veins, which would prove to be of substantial value to the knowledge of vessels in the pelvis, both for clinicians and surgeons. Materials and Methods In the present study, we came across a rare communication in the form of a ladder, between the left internal and external iliac veins in a 70-year-old male cadaver. There were two communications (named upper and lower communications) between the external and internal iliac veins, before they joined to form the common iliac vein. On naked eye observation, the lumen of the right common iliac vein appeared to be wider than on the left side. The lengths of these communications and the distance between each of their attachments have been measured and tabulated. The walls of these veins, their microscopic sections and their communication involved in the case were taken. The possible causes for these variations were congenital, owing to the complicated nature of the developmental process involved in the formation of the inferior vena cava and the venous system of the lower limb. Results The structure of all the veins involved in this case and the communications were seen to be normal. The thickness of these walls were measured and tabulated for uniformity around the circumference of the wall of these veins. All the measurements from the structural variations and from the histological observations are tabulated in our results. Conclusion The complicated development sequence of these veins could have possibly led to the persistence of these communications. Such a developmental variation does not seem to pose any threat until unless encountered under clinical or surgical interventions, as the histological structure of the walls of the communications as well as the major channels connected appeared to be normal and well-developed. The detailed morphological and histological features of these structures involved in the variation along with the possible complications have been presented in the present report. Knowledge of these variations and complications due to injury plays a key role in a clinical setup.

ABSTRACT Objective: to assess the incidence of pediatric vascular injuries in patients treated at the Emergency Room of the Eastern Children's Hospital, in Manaus. Methods: we conducted a retrospective study of pediatric patients who suffered vascular injuries treated between February 2001 to February 2012. Results: we studied 71 patients, predominantly male (78.87%), with a mean age of 7.63 years. The predominant mechanism of injury was stab wound in 27 patients (38.03%). The average hospital stay was 10.18 days; 16 patients required care in intensive care unit, with average stay of 8.81 days. The main injuries occurred in the extremities, the upper limb being the most affected, with lesions of the ulnar artery in 13 (15.66%) and radial in 10 (12.04%). The mostly applied procedure was vascular exploration 35 (32.4%). Complications occurred in nine patients (12.68%). Mortality was 1.4%, in one patient with a lesion of the common iliac vein and the inferior vena cava due fall from height. Conclusion: pediatric vascular injury occurred predominantly in the extremities. The dimensions of the injured vessels made surgical correction more complex and increased complication rates, particularly amputations.
