Background Venous malformation (VM) is a common vascular malformation in soft tissue. Surgical management plays an important role in its treatment. The location, extent, and adjacent anatomy of the lesion are crucial information for the safety of operation. This study introduces the application of magnetic resonance imaging and percutaneous sinus angiography/three-dimensional computed tomography imaging in gathering above information. Methods A retrospective analysis was made in the patients with venous malformation from January 2012 to June 2014 in our clinic. All patients underwent magnetic resonance imaging and percutaneous sinus angiography/three-dimensional computed tomography imaging. The location, extent of the lesion, its draining veins, and the relationship with around tissues were showed. Surgical management was carried out in the lesions which were well defined, located in the superficial fascia without important vessels and nerves across it. The wound was repaired by skin flap or skin graft. Results A total of 13 patients underwent complete surgical removal of the lesions, including five type I venous malformations and eight type II venous malformations. Ten lesions were removed by undermining dissection, and the wound was repaired by the undermined flap. Three superficial lesions were removed together with the skin over it, and the wound was repaired by the skin graft. In the six months to two years of follow-up period, none of the recurrence of the lesion was observed. Conclusion Magnetic resonance imaging and percutaneous sinus angiography/three-dimensional computed tomography imaging can display abundant morphological details of venous malformation, which are helpful for the surgical management.

Abstract We present two cases of patients with iatrogenic femoral arteriovenous fistula who underwent successful embolisation using three-dimensional shape detachable coils. A 49-year-old male with Tetralogy of Fallot had arteriovenous fistula which developed from the common femoral artery to the femoral vein with an aneurysm and a 17-year-old female with single ventricle after total-cavo-pulmonary-connection had two arteriovenous fistulas which developed from the internal iliac artery to the femoral vein. A total of six and seven pieces of detachable coils were necessary for complete occlusion, respectively. No complications were recorded. The advantage of the detachable coil is a wide variation and repositioning until the coil achieves good stabilisation and an ideal configuration.

Objectives Intermuscular venous malformations are common vascular malformation, do not have typical symptoms, and are difficult to diagnose. This article is a retrospective analysis of the diagnostic and therapeutic measures of intermuscular venous malformations. Methods From January 2013 to June 2018, 21 patients were included in this study. The clinical presentations, managements, and follow-up results were retrospectively analyzed. The indications and potential risks of different treatments were summarized. Results The complaints of patients with intermuscular venous malformations included local pain, swelling, discomfort, or aggravation after activity. Ultrasound, phlebography, magnetic resonance imaging, percutaneous sinus angiography, and three-dimensional computed tomography imaging were performed. The patients received surgical excision, sclerotherapy, or the combinational therapy of intralesional copper wires retention and ethanol injection and were followed for six months to five years. All patients’ symptoms were relieved largely. The lesions evaluated by magnetic resonance imaging decreased apparently or disappeared. Conclusions Imaging examinations are necessary in the diagnosis of intermuscular venous malformations and can guide the choice of treatment. Individualized treatment for intermuscular venous malformations should be made to achieve good effect and avoid adverse effects.

Background Catheter directed sclerotherapy (CDS) involves the use of a long catheter to deliver a sclerosing agent into a target vessel (saphenous trunks or venous malformations) under ultrasound guidance. Aims and Methods This article reviews the history, current techniques and devices and the evidence as it relates to these procedures. Results CDS was developed to increase the safety and efficacy of ultrasound-guided sclerotherapy (UGS). With the advent of foam sclerosants and tumescent anaesthesia, the procedure has enjoyed a higher primary success rate. CDS has a better safety profile when compared with UGS with virtually no risk of intra-arterial injection or sclerosant extravasation. Compared with endovenous laser (EVLA) and radiofrequency ablation (RFA), CDS is a quicker procedure with less associated pain. Some balloon catheters, however, have been found to force the sclerosant down the perforators causing femoral vein occlusion. Based on the current level of evidence, no firm conclusion regarding the efficacy of CDS techniques can be drawn in comparison with EVLA or RFA, but the primary success rate is probably higher than the standard UGS. Conclusion CDS ensures a safe intraluminal delivery of the sclerosing agent into the trunk of the saphenous veins using a single access point. This procedure preceded EVLA and RFA, and remains a safe alternative for the treatment of saphenous incompetence and venous malformations.

Background Understanding the anatomy of the lower extremity veins is essential for successful varicose vein treatment. Computed tomography (CT) venography may be used to obtain a comprehensive overview and detailed information regarding this. Purpose To describe anatomic variations of the lower extremity venous system in patients with varicose veins, using three-dimensional (3D) CT venography. Material and Methods A total of 810 limbs in 405 patients with suspected varicose veins were prospectively referred to undertake CT venography and included in our study population retrospectively. The CT venography images were evaluated by consensus of two cardiovascular radiologists. Anatomical variations of the lower extremity venous system and their incidence were analyzed. Specifically, the number of tributaries at saphenofemoral junction, relative location of the great saphenous vein (GSV) with respect to the common femoral artery bifurcation, pattern of saphenopopliteal junction, and end of thigh extension from the small saphenous vein (SSV) were assessed. Results The most frequent number of tributaries joining the GSV was four (44.4%, 360/810). Only 0.7% (6/810) of the limbs demonstrated unusual location of the GSV between the bifurcated superficial and deep femoral arteries. The most common pattern of veins at the saphenopopliteal junction was a larger caliber of saphenopopliteal junction than thigh extension from SSV (43.8%, 355/810), end of which joining the femoral vein directly (41.0%, 288/703). Conclusion CT venography with 3D reconstruction can be used to understand the anatomy of lower extremity veins and how their variations contribute to varicose veins.

Resonance Relation

The paper presents a summary of the results obtained by C. J. Cohen and E. C. Hubbard, who established by numerical integration that a resonance relation exists between the orbits of Neptune and Pluto. The problem may be explored further by approximating the motion of Pluto by that of a particle with negligible mass in the three-dimensional (circular) restricted problem. The mass of Pluto and the eccentricity of Neptune's orbit are ignored in this approximation. Significant features of the problem appear to be the presence of two critical arguments and the possibility that the orbit may be related to a periodic orbit of the third kind.
