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.

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 Purpose To assess the rate, timing of diagnosis, and repairing strategies of vascular injuries in thoracic and lumbar spine surgery as their relationship to the approach. Methods PubMed, Medline, and Embase databases were utilized for a comprehensive literature search based on keywords and mesh terms to find articles reporting iatrogenic vascular injury during thoracic and lumbar spine surgery. English articles published in the last ten years were selected. The search was refined based on best match and relevance. Results Fifty-six articles were eligible, for a cumulative volume of 261 lesions. Vascular injuries occurred in 82% of instrumented procedures and in 59% during anterior approaches. The common iliac vein (CIV) was the most involved vessel, injured in 49% of anterior lumbar approaches. Common iliac artery, CIV, and aorta were affected in 40%, 28%, and 28% of posterior approaches, respectively. Segmental arteries were injured in 68% of lateral approaches. Direct vessel laceration occurred in 81% of cases and recognized intraoperatively in 39% of cases. Conclusions Incidence of iatrogenic vascular injuries during thoracic and lumbar spine surgery is low but associated with an overall mortality rate up to 65%, of which less than 1% for anterior approaches and more than 50% for posterior ones. Anterior approaches for instrumented procedures are at risk of direct avulsion of CIV. Posterior instrumented fusions are at risk for injuries of iliac vessels and aorta. Lateral routes are frequently associated with lesions of segmental vessels. Suture repair and endovascular techniques are useful in the management of these severe complications.

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

The iliocaval compression syndrome is a disorder, frequently found in young women, in which extrinsic compression of the left iliocaval junction produces signs and symptoms of lower extremity venous insufficiency. The anatomic variant which gives rise to this syndrome consists of compression of the left common iliac vein by the overlying right common iliac artery, near its junction with the vena cava. Additional reduction of outflow results from intraluminal venous webs and tight adhesions between the iliac artery and vein. Pain, swelling, pigmentation, and venous claudication characterize this syndrome, which affects predominantly the left leg. The syndrome may progress to iliofemoral thrombosis, phlegmasia cerulea dolens, and venous gangrene. Longstanding iliocaval stenosis may produce valvular incompetence. Exercise plethysmography is a non-invasive test useful in screening patients for iliocaval compression. The definitive diagnosis is made by venography, both ascending and descending, to determine the degree of outflow stenosis. Iliocaval patch angioplasty with retrocaval positioning of the right iliac artery, decreases venous hypertension and leads to improvement in the clinical condition. To date, we have performed iliocaval angioplasty, with retrocaval repositioning of the right common iliac artery, on 18 patients. Of these, 83% have had good results as determined by hemodynamic and clinical assessment.

May-Thurner syndrome (MTS) is a venous outflow obstruction disorder characterized by compression of the left common iliac vein by an overriding right common iliac artery. MTS primarily affects young to middle-aged women, although many patients remain entirely asymptomatic. Anatomic variations of MTS, while uncommon, have been described. Treatment usually involves endovascular management, including thrombolysis and/or thrombectomy with or without inferior vena cava filter placement, followed by angioplasty and stenting of the left common iliac vein. We report a unique case of a 31-year-old woman who presented with MTS-related deep vein thrombosis accompanied by symptomatic abdominal and pelvic varicosities. The varicosities were treated successfully using multiple procedures, resulting in complete resolution of all symptoms. Our case discusses a treatment approach for an unusual presentation of MTS-related postthrombotic syndrome, and provides a brief literature review of MTS complications and management.
