Compression syndrome of distal peripheral aneurysms of the upper limb.

True aneurysm of the radial artery is very rare. Aneurysmal expansion of arteries due to degenerative changes, possibly infections, primarily affects the abdominal and thoracic aorta, intra and extracranial sections of cerebral arteries, popliteal artery, and visceral arteries. Published literature does not address the aneurysm on the distal sections of the arteries of upper or lower limb. Unlike the classic symptoms of aneurysmally altered arteries such as rupture, thrombosis and embolization, we encounter more often vascular compression syndrome in distal peripheral aneurysms. We demonstrate the case management of a patient with over 20 years increasing wrist resistance. A fusiform aneurysm of the distal section of the radial artery was identified by sonography. Under general anesthesia, we performed aneurysm resection and artery reconstruction using an interpositum from the ipsilateral cephalic vein. The histological examination of the resected tissue confirmed the presence of all three layers of the vascular wall, confirming the true aneurysm of the radial artery. No complications developed in the patient in the postoperative period and all problems related to the aneurysm subsided (Fig. 4, Ref. 23). Keywords: aneurysm, arteria radialis, surgical reconstruction.

Superior mesenteric vein thrombosis - unusual management of unusual complication of Whipple procedure.

INTRODUCTION: Pancreatoduodenectomy is an extensive procedure carrying risk of a number of postoperative complications. Of these the most common are surgical site infections (SSI), bleeding, delayed gastric emptying, and anastomotic leakage. However, the most serious complications are ones, that are rare, clinically hardly diagnosed, and if untreated, leading to the death of a patient. Among the latter complications is thrombosis of superior mesenteric vein. Its clinical signs are unspecific and diagnostics complicated. Treatment requires aggressive approach. If this is absent, intestinal necrosis with septic state, Multiple Organ Dysfunction Syndrome (MODS) and Multiple Organ Failure (MOF) lead to a death of a patient. PRESENTATION OF CASE: Authors present a case of a patient after pancreatoduodenectomy, complicated by the thrombosis of superior mesenteric vein. Patient was managed by resection of the necrotic bowel, venous decompression by venous bypass from superior mesenteric vein to the right ovarian vein, and open abdomen with negative pressure wound therapy (NPWT). Patient suffered severe abdominal sepsis with need for intensive organ support. Abdomen was definitely closed on fourth NPWT redress. Patient healed without any further complications, is well and was released to the ambulatory setting. DISCUSSION: Superior mesenteric vein (VMS) thrombosis is a rare complication. It diagnosis requires high level of vigilance and once diagnosed, aggressive therapy is essential. Two goals of surgical treatment exist: resection of the necrotic bowel and facilitation of the blood outflow. CONCLUSION: Mesenteroovarian anastomosis is one of the options in treatment of thrombosis of VMS if thrombectomy is not feasible.

No difference in intra-arterial and intramuscular delivery of autologous bone marrow cells in patients with advanced critical limb ischemia.

Stem cell therapy has been proposed to be an alternative therapy in patients with critical limb ischemia (CLI), not eligible for endovascular or surgical revascularization. We compared the therapeutic effects of intramuscular (IM) and intra-arterial (IA) delivery of bone marrow cells (BMCs) and investigated the factors associated with therapeutic benefits. Forty-one patients (mean age, 66 ± 10 years; 35 males) with advanced CLI (Rutherford category, 5 and 6) not eligible for revascularization were randomized to treatment with 40 ml BMCs using local IM (n = 21) or selective IA infusion (n = 20). Primary endpoints were limb salvage and wound healing. Secondary endpoints were changes in transcutaneous oxygen pressure (tcpO(2)), quality-of-life questionnaire (EQ5D), ankle-brachial index (ABI), and pain scale (0-10). Patients with limb salvage and wound healing were considered to be responders to BMC therapy. At 6-month follow-up, overall limb salvage was 73% (27/37) and 10 subjects underwent major amputation. Four patients died unrelated to stem cell therapy. There was significant improvement in tcpO(2) (15 ± 10 to 29 ± 13 mmHg, p < 0.001), pain scale (4.4 ± 2.6 to 0.9 ± 1.4, p < 0.001), and EQ5D (51 ± 15 to 70 ± 13, p < 0.001) and a significant decrease in the Rutherford category of CLI (5.0 ± 0.2 to 4.3 ± 1.6, p < 0.01). There were no differences among functional parameters in patients undergoing IM versus IA delivery. Responders (n = 27) were characterized by higher CD34(+) cell counts in the bone marrow concentrate (CD34(+) 29 ± 15×10(6) vs. 17 ± 12×10(6), p < 0.05) despite a similar number of total nucleated cells (4.3 ± 1.4×10(9) vs. 4.1 ± 1.2×10(9), p = 0.66) and by a lower level of C-reactive protein (18 ± 28 vs. 100 ± 96 mg/L, p < 0.05) as well as serum leukocytes (8.3 ± 2.1×10(9)/L vs. 12.3 ± 4.5×10(9)/L, p < 0.05) as compared with nonresponders (10 patients). Both IM and IA delivery of autologous stem cells are effective therapeutic strategies in patients with CLI. A higher concentration of CD34(+) cells and a lower degree of inflammation are associated with better clinical therapeutic responses.

Anti-cytomegalovirus antibodies and other atherosclerosis risk factors in patients with cardiovascular diseases / 老年心脏病学杂志（英文版）

Objective To determine anti-cytomegalovirus (CMV) antibodies along with anti-Chlamydia pneumoniae (CP)antibodies in comparison with inflammatory markers and other risk factors of atherosclerosis in patients with selected cardiovascular diseases(CVD).Methods A total of 228 patients with coronary heart disease (CHD) and/or hypertension (HT), and those who underwent reconstructive vascular surgery (RVS) on carotids or abdominal aorta were tested for the presence of anti-CMV IgG and IgM antibodies as well as for anti-CP IgA antibodies, C-reactive protein (CRP),and interleukin-6 (IL-6). Other risk factors for atherosclerosis, namely age, gender,smoking, hypercholesterolemia, and diabetes mellitus were also analyzed. Results Anti-CMV IgG antibodies were found in 204 patients sera (89.5%),compared with 46 positive of 68 sera in the controls (67.6%), whereas anti-CMV IgM antibodies were detected in 4 of 54 sera of patients tested (7.4%), but not in the controls. The highest proportion of positive sera with not only anti-CMV IgG antibodies (95.6.7%),but also anti-CP IgA antibodies (78.3%), IL-6 (84.8%) and CRP (97.8%), was observed in patients with RVS. The results obtained corresponded to age, hypercholesterolemia, and diabetes. Conclusions The presence of anti-CMV antibodies together with antibodies to CP and markers of inflammation (CRP and IL-6) in our study was associated with CVD, primarily in elderly patients who underwent RVS.
