Veinous thrombectomy. Six case reports]

The aim of this study is to raise up the effect of surgical thrombectomy among other alternative therapies. This retrospective study reports 6 patients (mean age 63 years) admitted with phlegmasia cerulea dolens. All patients underwent surgical venous thrombectomy associated with infracava filter insertion in 2 cases. One patient died in the early postoperative course. In all other cases we noticed good early and late outcome both on clinical examination and duplex scanning assessment. In conclusion, surgical venous thrombectomy can be considered as a good and efficient procedure in the presence of phlegmasia cerulea dolens in order to relieve ischemia and to prevent whenever possible severe chronic venous disorders. However, fibrinolytic therapy might achieve as good results as surgery. Thus, the latter is to be reserved to very severe veinous ischemia with limb loss threatening where fibrinolytic therapy fails or is contre-indicated.     

Analysis of MHC genes in a Tunisian isolate with autoimmune thyroid diseases: implication of TNF -308 gene polymorphism

Autoimmune thyroid diseases (AITDs), which include Hashimoto thyroiditis (HT), Graves' disease (GD) and primary idiopathic myxoedema (PIM), are recognized as multifactorial diseases. In this study, we have examined single and haplotypic genetic variation across the major histocompatibility complex (MHC) in a Tunisian isolate with a high prevalence of AITDs (62 patients: 32 with GD, 9 with HT and 21 with PIM). Genotyping was performed for HLA class I and II alleles as well as polymorphisms within tumor necrosis factor (TNF), lymphotoxin alpha (TLalpha) and heat shock protein (HSP70-02 and HSP70-hom) genes. Our results showed association of HLA-A2-B50-TNF 2 haplotype with AITDs (p = 0.045). Linkage analysis using Simwalk2 program has shown significant result with TNF -308 gene polymorphism (p = 0.03). The FBAT has given evidence for genetic association with TNF -308 and HLA-DR gene polymorphisms. TNF 2 allele was associated with GD (p = 0.0011), whereas TNF 1, HLA-DR11 and DR12 (p = 0.0039, p = 0.00089 and p = 0.0056, respectively) were rather implicated in HT pathogenesis. Results found by TDT-STDT have confirmed the involvement of the TNF -308 gene polymorphism in AITD pathogenesis (p < 10(-9)).     

Cavopulmonary shunts: apropos of 40 observations

Fourty patients with univentricular heart, underwent a cavopulmonary shunt procedure. The majority have an excellent hemodynamic status with ventricular end diastolic pressure > 12 mmHg and a mean pulmonary artery pressure > 15 mmHg. However, 11 patients have ventricular dysfunction, 9 have an incompetent systemic atrio-ventricular valve and 6 have mean pulmonary artery pressure > 15 mmHg. The pulmonary arteries were of a good size in all cases with a Nakata index > 100 mm2/m2. Cavopulmonary connections are satisfactory palliative procedures in the treatment of univentricular cardiac disease.

Anatomical basis of laparoscopic medial‐to‐lateral mobilization of the descending colon

In laparoscopic colorectal resection, the medial‐to‐lateral approach has been largely adopted. This approach can be initiated by the division of either the inferior mesenteric artery (IMA) or the inferior mesenteric vein (IMV). This cadaveric study aimed to establish the feasibility of IMV dissection as the initial landmark of medial‐to‐lateral left colonic mobilization for evaluating the size of the peritoneal window between the IMV at the lower part of the pancreas and the origin of the IMA (IMA‐IMV distance) and the point of origin of the IMA compared to the lower edge of the third part of the duodenum (IMA‐D3 distance). These distances were recorded on 30 fresh cadavers. The IMA‐D3 distance was 0.4 ± 2.2 cm (mean ± SD). The IMA originated from the aorta at the level of or below the D3 in 21 cases (70%). The IMA‐IMV distance was 5.5 ± 1.8 cm and was greater or equal to 5 cm (large window) in 21 cases (70%). IMA‐IMV distance was correlated with IMA‐D3 showing that a large window was inversely correlated with a low IMA origin (P < 0.001). IMA‐D3 distance was not correlated with weight, height and sex. IMA‐IMV distance was largerin male (6.7 ± 0.9 vs. 4.9 ± 1.8, P = 0.001) and correlated with weight, (r = 0.60, 95%CI = 0.03–0.10, P < 0.001) and height (r = 0.54, 95%CI = 0.05–0.21, P = 0.002). IMV can be used as the initial landmark for laparoscopic medial‐to‐lateral dissection in two‐thirds of cases. A too‐small window can require first IMA division. The choice between the two different medial‐to‐lateral approaches could be made by evaluating the anatomical relationship between IMA, IMV, and D3. Clin. Anat., 2013. © 2013 Wiley Periodicals, Inc.
