RESUMO
Objective:To investigate the feasibility and clinical value of endovascular treatment of iliac vein disease via the great saphenous vein approach.Methods:Eighty-six patients with nonthrombotic left iliac vein compression lesions identified by anterograde lower limb vein angiography were divided into 2 groups: group A ( n=46) was treated via great saphenous vein and group B ( n=40) was treated via femoral vein. The success rate of puncture, time consuming of puncture catheterization, postoperative bed immobilization and complication rate of puncture were observed and compared between the two groups. Results:The puncture success rate was 97.8% (45/46) in group A and 100% (40/40) in group B, there was no significant difference between the two groups( P>0.05). The average puncture time was (9.4±2.7) min in group A and (5.5±1.3) min in group B ( P<0.05). The complication rate of group A was lower than that in group B ( P<0.05). The patency rate of iliac vein stent was 100%, as indicated by venous color ultrasound or angiography. Conclusion:Endovascular treatment of iliac vein disease via great saphenous vein approach is a safe and feasible method with less trauma and easier postoperative care.
RESUMO
Objective:To evaluate the clinical efficacy of metal braided stent deployed by fully protruding into the inferior vena cava for the treatment of iliac vein compression syndrome(IVCS).Methods:The clinical data of patients with IVCS treated with interwoven nitinol mesh stent protruding into the inferior vena cava and released from Jan 2018 to May 2021 in our center were retrospectively analyzed.Results:A total of 118 patients were included in this study. Among them, 7 cases were complicated with acute thrombosis, 3 cases were complicated with post thrombotic syndrome (PTS), and 108 cases were no more thrombotic iliac vein compression. The technical success rate was 100%, with an average of 2.03±0.77 stents implanted. Of the 23 ulcer patients, 18 ulcers healed after intervention, and the healing rate was 78.26%. The postoperative CEAP grade was significantly improved ( t=11.54, P<0.01), and the primary patency rate and second patency rate were 97.46% and 98.31% at 1 year after intervention. Conclusion:The fashion of fully protruding into inferior vena cava deployment in the treatment of iliac vein compressive disease has a high patency rate and satisfactory clinical efficacy.
RESUMO
Objective To investigate effects of human postures on flow characteristics of iliac vein compression syndrome. Methods The numerical model of iliac vein was reconstructed from CT images of a typical patient with pelvic-type iliac vein compression syndrome with collateral veins. Based on the computational fluid dynamics method, the non-Newtonian model and the porous media model were adopted to describe effects of abnormal structures on blood flow and acquire the wall shear stress and pressure of iliac vein. The discrete phase model was used to study the residence conditions of erythrocytes under three human postures. Results The pressure gradient at two ends of the compressive region was lowest under lying state, while the iliac vein showed a high pressure under sitting and walking states. The local maximum wall shear stresses under three postures were found at narrow segment of the collateral vein and convergence region of two flows of right iliac vein. The maximum shear stress was largest under lying state and smallest under sitting state. The blood residence time of 52.2 s in the left iliac vein was the longest under sitting state. The residence time of 14.8 s was shortest under lying state. The blood residence time was 23.8 s under walking state. Conclusions Porous media model used to simulate the effect of abnormal structures was highly consistent with the angiography data. The venous hypertension under sitting and walking states was consistent with the clinical results, and the lying state could relieve the hypertensive condition. In terms of wall shear stress and blood residence time in iliac vein, the continual change between three human postures would cause endothelial damage and blood flow stasis alternately, thus increase the risk of thrombosis.
RESUMO
SUMMARY: The leg muscles are organized in anterior, lateral and posterior compartments. The posterior compartment is usually divided in two layers: superficial and deep. The deep muscles of the posterior compartment of the leg are known to mainly plantar flexion and toes flexion. In comparison to the other leg compartments, variations of the posterior one are rare. These variants often involve the presence or absence of one or more muscles, and they have differences among origin and insertion, which leads to confusion between anatomists. We aim to describe a case of a male cadaver that possessed three supernumerary muscles in the lateral and posterior compartments of both legs: the peroneus quartus muscle and two accessory bellies of the flexor digitorum longus. This presentation seems to be very rare and scarcely reported in the literature. These variants have the potential of causing nervous or vascular compression, thus leading to tarsal tunnel syndrome or a symptomatic peroneus quartus. The clinical and surgical implications of this abnormal presentation is discussed.
RESUMEN: Los músculos de la pierna están organizados en compartimentos anterior, lateral y posterior. El compartimento posterior por lo general es dividido en dos capas: superficial y profunda. Se sabe que los músculos profundos del compartimento posterior de la pierna se caracterizan principalmente por participar de la flexión plantar y la flexión de los dedos de los pies. En comparación con los otros compartimentos de la pierna, las variaciones musculares en el compartimiento posterior son raras. Estas variantes suelen implicar la presencia o ausencia de uno o más músculos y presentan diferencias en el origen y en la inserción, lo que conduce a confusión entre los anatomistas. Nuestro objetivo fue describir el caso de un cadáver masculino que poseía tres músculos supernumerarios en los compartimentos lateral y posterior de ambas piernas: el músculo fibular cuarto y dos vientres accesorios del músculo flexor largo de los dedos. Esta presentación parece ser muy rara y escasamente reportada en la literatura. Estas variantes musculares tienen el potencial de causar compresión nerviosa o vascular, lo que conduce al síndrome del túnel del tarso o un cuarto músculo fibular sintomático. Se discuten las implicaciones clínicas y quirúrgicas de esta presentación anormal.

Objective:To evaluate the application value of three-dimension digital subtraction angiography (3D-DSA) in the diagnosis and treatment of iliac vein compression syndrome (IVCS).Methods:A retrospective analysis was made on 171 patients with a tentative diagnosis of IVCS based on signs, symptoms, and finding of CTV or MRV, and iliac vein angiography. The diagnostic efficacy of MRV, 2D-DSA and 3D-DSA were analyzed. The imaging advantages of 3D-DSA in the diagnosis and treatment of IVCS were evaluated.Results:Ninty-three patients underwent MRV and 3D-DSA simultaneously, 101 patients had 2D-DSA and 3D-DSA simultaneously. 3D-DSA was taken as gold standard, the diagonotic sensitivity, specificity, Youden index of MRV was 75.61%, 72.73% and 0.48 respectively. The sensitivity, specificity, Youden index of 2D-DSA was 90.22%, 100% and 0.90 respectively. There are significant differences in the diagonotic sensitivity between MRV and 3D-DSA, 2D-DSA and 3D-DSA ( P<0.05). There is no significant difference in the diagonotic specificity between MRV and 3D-DSA, 2D-DSA and 3D-DSA ( P=1.000). In this study, we found that 3D-DSA has greater imaging evaluation advantages in preoperative evaluation, intraoperative guidance and immediate postoperative reexamination in the diagnosis and treatment of iliac vein disease. Conclusions:3D-DSA can improve the detection rate of IVCS, and has its advantage in imaging evaluation.
RESUMO
Objective To explore the relationship between the establishment of collateral circulation caused by iliac vein compression syndrom(IVCS) and the deep venous thrombosis (DVT). Methods Different types of ideal collateral circulation models and IVCS patient-specific models were numerically simulated using computational fluid dynamics (CFD) in combination with the blood stasis model. The relationship between blood retention and collateral types and cross-sectional area was studied, and the relationship with thrombosis was explored. Results Wall shear stress (WSS) at the distal end part of each ideal model was 0.3 Pa. After four cardiac cycles, the residual blood stayed at the stenosis and the distal end part for the lumbar ascending and pelvic type models, the old blood volume fraction (OBVF) varied with collateral cross-sectional areas, ranging from 5%-90% and 70%-80%, respectively. The OBVF of the coexistence model was above 80%. The WSS at the distal end part of the patient-specific model was 0.9 Pa, and the OBVF at the distal end part was 51.5%. Conclusions The stenosis and the distal end part are most prone to blood stasis, and closely related with DVT. The larger the collateral cross-sectional area, the more serious the blood stagnation. Blood stagnation of the coexistence model is higher compared with the model with lumbar ascending type and pelvic type.
RESUMO
@#Superior mesenteric artery (SMA) syndrome is rare with the common presentation of megaduodenum from entrapment of the third part of the duodenum (D3) by the SMA. We present a case report of a thin, fit 16-year-old boy, active smoker complaining of generalized colicky abdominal pain associated with persistent postprandial vomiting. Small bowel study demonstrated partial duodenal obstruction from compression of the third part of the duodenum by the SMA. Computed tomography of the abdomen shows an aorto-mesenteric angle of 13 degrees with aorto-mesenteric distance of 0.32 cm, indicating SMA syndrome. His symptoms resolved spontaneously with watchful waiting and nutritional care plan. The success was contributed to restoring the fat cushion around the SMA, hence, widening the aorto-mesenteric angle. In conclusion, watchful waiting with a nutritional care plan is a feasible initial strategy in the approach to SMA syndrome. However, should this strategy be unsuccessful, the choice of surgical treatment is duodenojejunostomy.
RESUMO
Objective:To evaluate the risk and influencing factors of pulmonary embolism in patients with iliac vein compression syndrome (IVCS) and acute iliofemoral vein thrombosis by CT pulmonary angiography combined with CT venography of inferior vena cava.Methods:The data of 166 patients with acute left iliofemoral vein thrombosis diagnosed in the Affiliated Hospital of Jining Medical University from July 2016 to June 2020 were analyzed retrospectively. All patients underwent one-stop CT pulmonary angiography combined with inferior vena cava CT venography. The patients were divided into IVCS group (101 cases) and non-IVCS group (65 cases) according to the presence or absence of IVCS. The general data of the patients, the stenosis rate of left common iliac vein, the presence of inferior vena cava floating thrombosis, the presence of large pelvic collateral veins, the detection of pulmonary embolism and the pulmonary artery obstruction index of the two groups were compared, and multivariate logistic regression and multiple linear regression were used to analyze the influencing factors of the incidence and severity of pulmonary embolism in IVCS group.Results:There were significant differences in the stenosis rate of left common iliac vein [(68±8)% vs (25±14)%, t=-25.300, P<0.001], the incidence of inferior vena cava floating thrombosis [25/101, 31/65, χ2 =9.310, P=0.002], the length of inferior vena cava floating thrombosis [17.2 (10.9, 27.8)mm vs 27.4 (20.1, 55.9) mm, Z=-2.316, P=0.021], the incidence of pulmonary embolism (43/101 vs 41/65, χ2 =6.651, P=0.010) and the pulmonary artery obstruction index [(10.0% (5.0%, 17.5%) vs 22.5% (10.0%, 30.0%), Z=-3.490, P<0.001] between IVCS group and non-IVCS group. In the IVCS group, multiple logistic regression analysis revealed that the stenosis rate of left common iliac vein [β=-1.964, OR(95%CI) 0.140(0.031-0.638), P=0.011] and inferior vena cava floating thrombosis [β=1.212, OR(95%CI) 3.360(1.566-7.209), P=0.002] was independent factors for the occurrence of pulmonary embolism. Multiple linear regression showed that the influence of inferior vena cava floating thrombosis on the pulmonary artery obstruction index was statistically significant (b=0.352, t=2.410, P=0.021). Conclusion:The incidence and severity of pulmonary embolism in patients with IVCS and acute left iliofemoral vein thrombosis are lower than those without IVCS, and the presence or absence of inferior vena cava floating thrombosis is an important factor affecting the severity of pulmonary embolism.
RESUMO
Objective@#To summarize the experience of diagnosis and treatment of superior mesenteric artery compression syndrome (SMACS) secondary to chronic constipation according to the concept of Lee′s triad syndrome.@*Methods@#The concept of Lee′s triad syndrome: (1) clinical symptoms: triad of constipation, malnutrition, upper gastrointestinal obstruction (vomiting, difficulty in eating); (2) anatomical manifestations: with triple anatomy anomaly of transverse colon sagging, elevated spleen flexure, and mesentery arterial compression; (3) treatment: with triple treatment of enteral nutrition support, chest-knee posture and fecal microbiota transplantation. A descriptive cohort study was performed. According to Lee′s triad syndrome criteria, clinical data of 78 patients with superior mesenteric artery compression syndrome secondary to chronic constipation in the Tenth People′s Hospital of Tongji University and General Hospital of Eastern Theater Command from June 2004 to November 2018 were prospectively collected, including basic information, symptoms and signs, imaging findings, nutritional indicators, gastrointestinal quality of life index (GIQLI) and Wexner defecation score. The above parameters based on Lee′s triad syndrome criteria were followed up and recorded at 1, 3, 6, 12 months after comprehensive treatment.@*Results@#All the patients had Lee′s triple symptoms of constipation, malnutrition, upper gastrointestinal obstruction (vomiting, eating difficulties), and triple anatomy anomaly of transverse colon sagging, elevated spleen curvature, and mesentery arterial compression before treatment. After triple treatment of enteral nutrition support, chest-knee posture, and fecal microbiota transplantation, 69 (88.5%) patients had a significant improvement of symptoms, and 9 patients had no significant improvement of symptoms and then eventually received surgery. The 69 cases without operation received follow-up for 12 months. All the patients eventually returned to normal eating, and upper gastrointestinal angiography and superior mesenteric artery imaging showed duodenal compression disappeared. After 1 month, the constipation-related indexes were improved. After 12 months, the number of autonomous defecation per week increased from 1.0±0.8 to 5.0±1.6 (P<0.001). The GIQLI score increased from 52.7±8.5 to 93.2±7.5 (P<0.001), and the Wexner score decreased from 19.1±2.5 to 6.2±2.1 (P<0.001). After 1 month, nutritional indexes were improved gradually. After 12 months, the BMI increased from (17.9±1.8) kg/m2 to (21.0±1.3) kg/m2, total protein increased from (65.2±5.7) g/L to (68.3±4.2) g/L, albumin increased from (32.1±5.1) g/L to (40.4±3.0) g/L, prealbumin increased from (163.2±53.7) mg/L to (259.1±45.6) mg/L, fibrinogen increased from (1.9±0.5) g/L to (2.4±0.5) g/L, whose differences were statistically significant (all P<0.001). Upper gastrointestinal angiography and superior mesenteric artery imaging showed duodenal compression were relieved. The angle between superior mesenteric artery and abdominal aorta increased from (17.4±3.8)° to (37.8±5.8)° (t=-22.26, P<0.001).@*Conclusion@#When patients with SMACS secondary to chronic constipation have Lee′s triple symptoms and triple anatomy anomaly, the triple combination treatment of enteral nutrition support, chest-knee posture and fecal microbiota transplantation should be applied.
RESUMO
ABSTRACT Background: Median arcuate ligament syndrome(MALS) is a rare condition thatmay cause significant clinical manifestations, including abdominal pain and weight loss. Its diagnosis may be difficult and very often delayed. The laparoscopic approach became the standard treatment of MALS. Aim: To assess the outcome of laparoscopic treatment in patients with MALS. Method: The data of sixpatients with MALS who were subjected to laparoscopic sectioning of the median arcuate ligament were retrospectively reviewed.The following data were evaluated: age, gender, clinical and diagnostic tests findings, ASA score, operative findings and complications, postoperative complications and mortality, hospital stay duration, and hospital readmission.The diagnosis of MALS was established by CT angiography and/or MR angiography. Results: There were four (66.7%) women and two (33.3%) men aged from 32 to 60 years. The main symptoms were epigastric pain (100%) and weight loss (66.7%). The findings of high-grade stenosis of the proximal celiac axis and poststenotic dilation confirmed on angiography confirmed the diagnosis in all patients. Surgical procedure was uneventful in all patients. The only postoperative complication was urinary retention that occurred in a male. At three-month follow-up, all patients were asymptomatic. Conclusion: Laparoscopic treatment of MALS is safe and effective in relieving the clinical manifestations of patients.
RESUMO Racional: A síndrome do ligamento arqueado mediano (SLAM) é condição rara que pode causar manifestações clínicas significativas, incluindo dor abdominal e perda de peso. Seu diagnóstico pode ser difícil e muitas vezes estabelecido tardiamente. A abordagem laparoscópica tornou-se o tratamento padrão para ela. Objetivo: Avaliar o resultado do tratamento laparoscópico em pacientes com SLAM. Método: Os dados de seis pacientes com SLAM submetidos a ressecção laparoscópica do ligamento arqueado mediano foram revisados retrospectivamente. Os seguintes dados avaliados foram: idade, gênero, resultados dosexames clínicos e complementares, escore ASA, achados e complicações operatórias, complicações e mortalidade pós-operatórias, tempo de internação e readmissão hospitalar. O diagnóstico de SLAM foi estabelecido por angiotomografia e/ou angiorressonância. Resultados: Havia quatro (66,7%) mulheres e dois (33,3%) homens com idades entre 32 e 60 anos. Os principais sintomas foram dor epigástrica (100%) e perda de peso (66,7%). Os achados de estenose de alto grau do tronco celíaco proximal e dilatação pós-estenótica observados na angiografia confirmaram o diagnóstico em todos os pacientes. O procedimento cirúrgico transcorreu sem intercorrências em todos os pacientes. A única complicação pós-operatória foi retenção urinária, que ocorreu em um homem. No seguimento de três meses, todos os pacientes estavam assintomáticos. Conclusão: O tratamento laparoscópico da SLAM é seguro e eficaz no alívio das manifestações clínicas dos pacientes.

Abdominal cutaneous nerve entrapment is a rarely diagnosed condition that leads to intense neuropathic pain in the anterolateral wall of the abdomen. Generally, it is triggered by some factor implied in the increase of the pressure on the nerve in its passage by the abdominal wall. Its most important differential diagnosis is pain of visceral origin. We present a case in which the clinical findings confirmed on ultrasound and other imaging tests established the diagnosis and in which the noninvasive treatment was effective.

Vasoocclusive crises in sickle cell disease commonly involve bone marrow of the long bones and vertebrae. Involvement of bones with less marrow space, including the bones of the orbit, is reported rarely in the literature. The present case is a 6-year-old boy, a known case of sickle cell disease, who presented with acute onset right upper and lower eyelid swelling, restriction of extraocular movement and pain. USG orbit showed a retroorbital hemorrhage compressing on the orbit, probably due to orbital bone infarction. The child was managed successfully with red blood cell transfusion and intravenous antibiotics, without steroids and surgical intervention. This report highlights the importance of maintaining a high index of suspicion in patients with known sickle cell disease presenting with pain, orbital swelling and restriction of ocular movement. Timely red blood cell transfusion only may be sufficient for uneventful recovery, without steroids or surgical intervention. Expedient diagnosis of orbital compression syndrome in children with sickle cell disease is crucial because this is a potentially sight-threatening entity.

Sin embargo, no es frecuente que ocurra como manifestación inicial. Se comunica el caso de un paciente de 40 años de edad diagnosticado con adenocarcinoma pulmonar que tuvo como manifestación inicial una paraplejía.
Abstract An important complication that occurs between 5 and 10% of patients with cancer is spinal cord compression syndrome that represents an oncological emergency. There is a relationship between lung cancer and spinal cord compression syndrome, because cancer can infiltrate the spine. However, it is not common to occur as an initial manifestation. We report the case of a 40-year-old patient diagnosed with pulmonary adenocarcinoma who had paraplegia as an initial manifestation.
RESUMO
Meralgia paresthetica (MP) is a neuropathic pain caused by the entrapment of the lateral femoral cutaneous nerve (LFCN). There have been reports of MP following various surgeries; however, it has not yet been reported after hemorrhoid surgery. We report a case of bilateral MP after hemorrhoid surgery in a jack-knife position. The patient presented with pain, tightness, and a tingling sensation in the anterolateral aspect of both thighs. Ultrasonography-guided LFCN block was used for diagnosis and treatment, along with conservative management for 20 days with oral medication. One month later, the patient's symptoms had resolved completely. MP due to the jack-knife position may occur postoperatively in patients with predisposing risk factors such as obesity and diabetes mellitus, despite adequate padding and a shorter operating time.

RESUMO
STUDY DESIGN: Retrospective analysis. PURPOSE: The present study aimed to investigate the features of low back pain (LBP) due to superior cluneal nerve (SCN) entrapment neuropathy (SCN-EN) using the Roland Morris Disability Questionnaire (RMDQ), and to analyze the differences between LBP due to SCN-EN and lumbar spinal canal stenosis (LSS). OVERVIEW OF LITERATURE: The SCN is derived from the cutaneous branches of the dorsal rami of T11–L5 and passes through the thoracolumbar fascia. LBP due to SCN-EN is exacerbated by various types of lumbar movement, and its features remain to be fully elucidated, often resulting in the misdiagnosis of lumbar spine disorder. METHODS: The present study included 35 consecutive patients with SCN-EN treated via nerve blocks or surgical release between April 2016 and August 2017 (SCN-EN group; 16 men, 19 women; mean age, 65.5±17.0 years; age range, 19–89 years). During the same period, 33 patients were surgically treated with LSS (LSS group; 19 men, 14 women; mean age, 65.3±12.0 years; age range, 35–84 years). The characteristics of LBP were then compared between patients with SCN-EN and those with LSS using the RMDQ. RESULTS: The duration of disease was significantly longer in the SCN-EN group than in the LSS group (26.0 vs. 16.0 months, p=0.012). Median RMDQ scores were significantly higher in the SCN-EN group (13 points; interquartile range, 8–15 points) than in the LSS group (7 points; interquartile range, 4–9 points; p<0.001). For seven items (question number 1, 8, 11, and 20–23), the ratio of positive responses was higher in the SCN-EN group than in the LSS group. CONCLUSIONS: Patients with SCN-EN exhibit significantly higher RMDQ scores and greater levels of disability due to LBP than patients with LSS. The findings further demonstrate that SCN-EN may affect physical and psychological function.
RESUMO
Thoracic outlet syndrome is a relatively well known disease. Other than trauma, this disease is mostly caused by anatomical structures that cause vascular or neural compression. The cause of thoracic outlet syndrome is diverse; however, there are only few reports of thoracic outlet syndrome caused by lipoma in the pectoralis minor space. We report a case of compression of the lower trunk of brachial plexus in which a large lipoma that developed in the pectoral minor space grew into the subclavicular space, along with a review of literature.

Celiac artery compression syndrome, also referred to as median arcuate ligament syndrome, celiac axis syndrome or Dunbar syndrome is a rare disorder consequent to extrinsic compression of the celiac trunk by the median arcuate ligament. Doppler ultrasound, multi-slice computed tomography angiography, magnetic resonance angiography, or invasive selective angiography can identify stenosis of the initial segment of the celiac artery and confirm diagnosis. Treatment options include open surgical or videolaparoscopic section of the median arcuate ligament and the fibers of the celiac plexus, or percutaneous transluminal angioplasty via an endovascular approach. We report herein an interesting case of a 38-year-old woman diagnosed with this rare condition and successfully treated with the surgical strategy
A síndrome da compressão da artéria celíaca, também denominada síndrome do ligamento arqueado mediano, síndrome do eixo celíaco ou síndrome de Dunbar, é uma doença rara causada pela compressão extrínseca do tronco celíaco pelo ligamento arqueado mediano. Ultrassonografia Doppler, angiotomografia computadorizada, angiorressonância magnética ou angiografia seletiva invasiva conseguem identificar a estenose do segmento inicial da artéria celíaca e confirmar o diagnóstico. As opções de tratamento incluem secção videolaparoscópica ou laparotômica (a céu aberto) do ligamento arqueado mediano e das fibras do plexo celíaco, assim como angioplastia transluminal percutânea. Relatamos o interessante caso de uma mulher de 38 anos de idade diagnosticada com essa rara condição e adequadamente tratada pela estratégia cirúrgica
