A malpractice: Stripping of the great saphenous vein without the division of the side-branches at the saphenofemoral junction.

AIM: To highlight the components of stripping operation of the great saphenous vein and to offer a proposal for guidelines. METHODS: 7789 admissions with venous insufficiency during the period, reaching seven and a half years were evaluated. Seventy- two admissions of nineteen patients were related to the recurrent symptoms due to previous incomplete stripping surgery. Doppler ultrasonography evaluations were made. The remained venous segment from the first operation was excised in the second operation. RESULTS: Mean duration between two operations was 7.44 years. Preoperative clinics were changing between C2s and C5 according to CEAP classification. Only nine patients could be persuaded to undergo the second operation. The remaining six patients rejected the second operation. CONCLUSION: While the patients who were operated on for the second time regained their health, others became the epitome of hopelessness and mistrust. They lost their confidence in medicine and surgery. If a stripping operation is planned, it should be performed in full accordance with the surgical procedure of stripping as mentioned in the classical textbooks. Guidelines should contain expressions reminding of ethical issues. This will prevent the dereliction of the duty and the loss of money, labor, time, health, patients' confidence in surgery (Tab. 1, Fig. 1, Ref. 18) Keywords: ethics, malpractice, quality of life, venous, saphenous, stripping.

The relationship between Raynaud's phenomenon and Helicobacter pylori.

BACKGROUND: This study was aimed to reveal whether there is a relationship between Raynaud Phenomenon (RP) and Helicobacter Pylori (HP). MATERIAL AND METHODS: Seventy-nine patients, who had been referred to outpatient clinic with Raynaud in the last 9 years were retrospectively screened. Of these, 29 patients with access to their data and who had HP screening tests were included in the study. RESULTS: HP direct antigen was found in feces in only one of 29 patients. When we compared the results of this study to the results of previous literature, it was observed that the patients admitted with RP symptoms by a gastroenterology outpatient clinic had a higher incidence for HP (+) scanning than the patients admitted with RP symptoms by a cardiovascular surgery policlinic (CVSOC). CONCLUSION: Although previous literature reports that HP leads to RP in the group of patients referred to other outpatient clinics, the same relation is very low in the Raynaud patient group in CVSOC. Patients admitted with RP in the CVSOC shouldn't be prescribed empirical antibiotic therapy for the eradication of HP. However, as the appropriate antibiotic regimen can resolve Raynaud symptoms in the presence of a HP(+) test, it makes this scanning rational for all symptomatic patients (Tab. 1, Fig. 1, Ref. 23).

A dilemma: prophylaxis for pulmonary embolism after surgical or invasive interventions for hemodialysis.

AIM: This study was designed to investigate if it needs to do prophylaxis for pulmonary embolism in the patients treated with different kinds of dialysis or not, and if it is, to find a proper method for prophylaxis. METHODS: Ten numbers of patients with central venous catheters (CVC group), 13 numbers of patients with arteriovenous fistula (AVF group) were enrolled in this study. Eleven patients treated with peritoneal dialysis (PD group) were utilized as a control group. Clinical and laboratory examinations to exclude pulmonary embolism were carried out in both AVF and PD groups at the onset and after three months. Same examinations were performed in CVC group at the onset and after 3 weeks (mean: 21 days). Examinations to exclude pulmonary embolism consist of medical history, clinical examinations, d-dimer measures, chest x-ray, respiratory function tests, blood gas analyses, ventilation-perfusion scintigraphies. RESULTS: Neither clinical nor laboratory findings in any stages reflected any suspicion for pulmonary embolism. None of the patients in any groups was admitted with pulmonary embolism in any period of follow-up. There was not any statistically difference between the outcomes of all first examinations and of all second ones (P>0.005). Neither obvious nor subclinical pulmonary embolism was detected in any case. None of the patients had deep venous thrombosis in any stage of follow-up. CONCLUSIONS: Conventional techniques of haemodialysis do not lead to pulmonary embolism unless deep venous thrombosis due to any intervention occurs in the patients. Thus, prophylactic anticoagulant usage to prevent pulmonary embolism is not necessary in haemodialysis patients. To shorten the length of stay of central venous catheters is the most important factors for pulmonary embolism prophylaxis in haemodialysis patients.

Early postoperative candida colonization in alimentary canal in patients undergoing open heart surgery.

AIM: To examine the frequency and factors predisposing to candidiasis in the digestive tract in the early postoperative period after open heart surgery. METHODS: One hundred patients undergoing open heart surgery were enrolled in this study. Patients were divided into 2 groups in regard to Candida spp. colonization. Group A means increased Candida spp. colonization after open heart surgery (31/100). Group B indicates unchanged Candida spp. colonization after open heart surgery (69/100). Samples were obtained from both oral and anal mucosa in 3 different periods of operation: 1) preoperatively (stage 1), 2) at the end of the first hour in the intensive care unit (stage 2), 3) 24 hours after operation (stage 3). Findings were compared with both preoperative and intraoperative parameters. For fungal isolation Sabourauds dextrose agar and blood agar were used. RESULTS: In Group A (31), there was a significant relationship between the samples in stage 1 and 2 (p=0.031), and also a significance between stage 1 and 3 (p=0.048). Comparison between Candida positive and negative groups (Group A and B) did not reflect any statistical significance (p>0.05). CONCLUSIONS: Candida colonization in the alimentary canal in the early postoperative period after open heart surgery is due to individual preoperative features. However, early postoperative Candida colonization in the digestive tract is not a risk factor for sepsis unless the patient has an additional risk factor leading to prolongation of length of stay in the intensive care unit.

Successful treatment of Buerger's Disease with intramedullary K-wire: the results of the first 11 extremities.

OBJECTIVE: This study describes a new technique for treatment of Buerger's disease, developed to stimulate angiogenesis, using a Kirschner wire placed in the medullary canal of the tibia. The aim of the study was to evaluate clinical and radiological effects of this technique in patients where medical and surgical therapy had failed. MATERIAL AND METHODS: Eleven extremities (six patients) with Buerger's disease were treated with the intramedullary Kirschner wire technique. Inclusion criteria were chronic critical ischemia, Rutherford Grade II or III, with major arterial occlusion shown by Doppler examination and angiography; failure to respond to non-surgical and surgical treatment; and the need for strong analgesics. RESULTS: The mean follow-up time was 19 months (range, 13-25 months). Satisfactory remission in each patient was obtained within 6 weeks of intervention. A significant improvement in clinical manifestations including reduced rest pain and increased claudication distance was observed. Foot ulcers completely healed after Kirschner wire intervention. CONCLUSION: Despite short-term follow-up and small patient series, the intramedullary Kirschner wire technique can be expected to achieve relief of pain and a decrease in major amputations in patients with Buerger's disease in whom medical and surgical therapy had failed. However, comparative studies with longer follow-up should be done to confirm the benefits of this new treatment.

Left ventricular diverticulum associated with Cantrell's syndrome and tetralogy of Fallot in an adult.

In this report we describe the surgical treatment of a 27-year-old patient with complete Cantrell's syndrome, i.e. multiple ventricular septal defect, left ventricular diverticulum, dextrorotation of the heart, an anterior diaphragmatic defect, and a midline supraumbilical abdominal wall defect with tetralogy of Fallot. Resection of the diverticulum was combined with correction of the tetralogy of Fallot and thoracoabdominal defects. The postoperative period was uncomplicated. We have have found only one previous report describing resection of the diverticulum combined with correction of Fallot's tetralogy and thoracoabdominal defects in an adult. One-stage repair of these complex anomalies is technically feasible and should be the treatment of choice.

The side-effects of cardiopulmonary bypass on the lungs: changes in bronchoalveolar lavage fluids.

Although technical refinements have improved the safety of cardiac operations, postoperative dysfunction of lung and other organs occurs frequently after cardiopulmonary bypass (CPB). The aim of the present study was to search the aetiopathogenesis of pulmonary complications due to CBP. Ten patients with stable coronary artery disease, undergoing coronary artery bypass grafting (CABG) surgery, were included in the study. Forty bronchoalveolar lavage (BAL) fluid samplings were performed in the 10 patients. Samples were obtained at the following time periods: (1) preoperatively; (2) at the end of the first hour after anaesthetic induction; (3) at the conclusion of 30 min of crossclamp on CPB; and (4) at the conclusion of 20 h after the end of CPB, postoperatively. Cell contents of bronchoalveolar lavage fluid, alveolar macrophage viability, eosinophil cationic protein (ECP) levels and myeloperoxidase (MPO) concentrations were analysed in each bronchoalveolar lavage fluids. While the percentage of preoperative macrophages was 85.90% and the percentage of preoperative neutrophils was 2.40%, they were 77.00% and 11.30% in the postoperative samples, respectively. Mean alveolar macrophage viability was 96.20% preoperatively and 90.40% in the postoperative period. Preoperative eosinophil cationic protein mean concentration was < 2 microg/l and mean response value (RV) was 28.80. Preoperative mean myeloperoxidase concentration was 7.66 ng/ml. Postoperative eosinophil cationic protein mean response value was 63.40 and mean myeloperoxidase concentration was 59.25 ng/ml. There were significant differences between third and final samples with regard to both neutrophil percentages (p = 0.028) and MPO levels (p = 0.005). While the preoperative mean PaO2 value was 89.39 mmHg and mean SaO2 value was 97.12%, they were calculated in the postoperative arterial blood specimens of patients, without inhaling O2, as 65.31 mmHg and 93.84%. These changes between blood gas analyses reflect the impairment of the lungs (p = 0.009 and p = 0.007, respectively). Neither alveolar macrophage viability nor ECP levels changed significantly between consecutive periods. However, when the results of the first and fourth samples were compared, we saw the cumulative effects of CPB, in that alveolar macrophages lost their viability and ECP mean RVs rose. These changes were statistically significant (p = 0.027 and p = 0.013, respectively). However, postoperative ECP levels were not like those found in a patient with asthma. Also, changes between alveolar macrophage percentages (p = 0.028), between neutrophil percentages (p = 0.036) and between MPO concentrations (p = 0.005) were statistically significant. Again, changes in neutrophil percentages between first and final samples correlated with changes in MPO levels between same periods (r = 0.657, p = 0.039).

Cardiac surgery with cardiopulmonary bypass in patients with chronic renal failure.

OBJECTIVE: Renal failure is known to increase the morbidity and mortality in patients undergoing cardiac surgery. The results of heart surgery in patients with non-dialysis-dependent, mild renal insufficiency are not clear. METHODS: One hundred nineteen adult patients with chronic renal failure underwent cardiac surgery. Group I consisted of 93 patients who had creatinine levels between 1.6 and 2.5 mg/dL but who were not supported by dialysis. Group II consisted of 18 patients with creatinine levels higher than 2.5 mg/dL who were not supported by dialysis. Group III consisted of 8 patients with end-stage renal disease who were receiving hemodialysis. RESULTS: The hospital mortality rates were 11.8%, 33.0%, and 12.5%, respectively. Morbidity was 21.5%, 44.4%, and 75.0%, respectively, in groups I, II, and III. Postoperative hemodialysis was needed in 2 (2.15%) patients from group I and 6 (33%) patients from group II. On multivariable logistic regression analysis, risk factors for mortality were preoperative creatinine level more than 2.5 mg/dL, angina class III-IV, emergency operation, excessive mediastinal hemorrhage, postoperative pulmonary insufficiency, low cardiac output, and rhythm disturbances. Risk factors for morbidity were preoperative creatinine level more than 2.5 mg/dL and postoperative dialysis. CONCLUSIONS: Chronic renal failure increases the mortality and morbidity in patients undergoing cardiac surgery. Renal insufficiency with creatinine levels higher than 2.5 mg/dL increases the risk of postoperative dialysis and prolongs the length of hospital stay. Careful preoperative management and intraoperative techniques, such as avoiding low perfusion pressure and using low-dose dopamine, may be useful for a good operative outcome.

Proximal clamping levels in abdominal aortic aneurysm surgery.

In the surgical treatment of abdominal aortic aneurysm, the single proximal cross-clamp can be placed at 3 alternative aortic levels: infrarenal, hiatal, and thoracic. We performed this retrospective study to evaluate the advantages and disadvantages of the 3 main aortic clamping locations. Eighty patients presented at our institution with abdominal aortic aneurysms from March 1993 through May 1998. Fifty of these patients had intact aneurysms and underwent elective surgery, and 30 had ruptured aneurysms that necessitated emergency surgery. Proximal aortic clamping was applied at the infrarenal level in 24 patients (22 from the intact aneurysm group, 2 from the ruptured group), at the hiatal level in 34 patients (22 intact, 12 ruptured), and at the thoracic level (descending aorta) via a limited left lateral thoracotomy in 22 patients (6 intact, 16 ruptured). Early mortality rates (within 30 days) were 4% (2 of 50 patients) among patients with intact aneurysms and 40% (12 of 30 patients) among those with ruptured aneurysms. In the 2 patients from the intact aneurysm group, proximal aortic clamps were applied at the hiatal level. In the ruptured aneurysm group, proximal aortic clamps were placed at the thoracic level in 10 patients, the infrarenal level in 1, and the hiatal level in 1. According to our study, the clinical status of the patient and the degree of operative urgency--as determined by the extent of the aneurysm--generally dictate the proximal clamp location. Patients who present with aneurysmal rupture or hypovolemic shock benefit from thoracic clamping, because it restores the blood pressure and allows time to replace the volume deficit. Infrarenal placement is advantageous in patients with intact aneurysms if there is sufficient space for the clamp between the renal arteries and the aortic aneurysm. In patients with juxtarenal aneurysms, hiatal clamping enables safe and easy anastomosis to the healthy aorta. Clamping at this level also helps prevent late anastomotic aneurysm formation, which is frequently encountered after inadvertent anastomosis of the graft to a diseased portion of the aorta. Further studies are needed in order to confirm these results.
