Abstract
OBJECTIVE The aim of this study was to assess the relationship between haemoglobin A1c (HbA1c) values and operative wound infection. METHOD During the period from 2013-2016, consecutive patients with type 2 diabetes were prospectively evaluated. Data were retrospectively analysed. All included patients were admitted for an elective surgical procedure, requiring the use of prosthetic graft in a groin wound. The patients were divided into two groups according to their preoperative HbA1c values. The main outcome was groin wound infection. The association between preoperative long-term glycoregulation and wound infection was evaluated, as well as the impact of postoperative glycaemic values, regardless of the level of HbA1c. RESULTS Of the 93 participating patients, wound infection occurred in 20 (21.5%). Wound infection occurred in 28.2% of patients with uncontrolled diabetes (HbA1c >7%) and 16.7% of patients with controlled diabetes (HbA1c <7%); however, the difference did not reach statistical significance (p=0.181). In regression modelling, operative time (p=0.042) was a significant predictor of wound infection, while patients' age (p=0.056) was on the borderline of statistical significance. Females had a higher probability for wound infection (odds ratio (OR): 1.739; 95% confidence interval (CI):0.483-6.265), but there was no statistical significance (p=0.397). Patients with elevated levels of HbA1c had a higher chance of wound infection compared with patients with controlled diabetes (OR: 2.243; 95% CI: 0.749-6.716), nevertheless, this was not statistically significant (p=0.149). CONCLUSION We found no statistically significant correlation between elevated values of preoperative HbA1c and postoperative groin wound infection.

Abstract
BACKGROUND: Arteriovenous fistulas (AVFs) are pathological, congenital, or acquired communications between the arterial and venous vascular bed. Asymptomatic AVFs do not require surgical or endovascular treatment; however, if they are symptomatic, they must be treated to relieve the patient of symptoms and cardiovascular disorders.
CASE PRESENTATION: Our patient had an undiagnosed AVF that became symptomatic after femoropopliteal bypass surgery. We successfully treated these complications with four cover stents.
CONCLUSION: The presence of AVFs should be kept in mind in the case of rapidly developing leg edema after revascularization. Endovascular treatment of symptomatic AVF is a safe and effective treatment modality. Treatment of symptomatic AVFs is not only recommended for improving impaired arterial or venous blood flow, but also for preventing recurrent PE.

Body mass index and early outcomes after carotid endarterectomy. PLoS One 2022; 17:e0278298. [PMID: 36538553 PMCID: PMC9767338 DOI: 10.1371/journal.pone.0278298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Accepted: 11/14/2022] [Indexed: 12/24/2022] Open
Abstract
As the existing data on the correlation of adiposity with adverse outcomes of carotid endarterectomy (CEA) are inconsistent, the aim of the present study is to examine the correlation of an increased body mass index with 30-day complications after carotid endarterectomy. The cohort study comprises 1586 CEAs, performed at the Clinic for Vascular Surgery in Belgrade, from 2012-2017. Out of them, 550 CEAs were performed in patients with normal body mass index (18.5-24.9), 750 in overweight (25.0-29.9), and 286 in obese (≥30) patients. The association of overweight and obesity with early outcomes of carotid endarterectomy was assessed using univariate and multivariate logistic regression analysis. Overweight patients, in whom CEAs were performed, were significantly more frequently males, compared to normal weight patients-Odds Ratio (OR) 1.51 (95% confidence interval- 1.19-1.89). Moreover, overweight patients significantly more frequently had non-insulin-dependent diabetes mellitus-OR 1.44 (1.09-1.90), and more frequently used ACEI in hospital discharge therapy-OR 1.41 (1.07-1.84) than normal weight patients. Additionally, the CEAs in them were less frequently followed by bleedings-OR 0.37 (0.16-0.83). Compared to normal weight patients, obese patients were significantly younger-OR 0.98 (0.96-0.99), and with insulin-dependent and non-insulin-dependent diabetes mellitus-OR 1.83 (1.09-3.06) and OR 2.13 (1.50-3.01) respectively. They also more frequently had increased triglyceride levels-OR 1.36 (1.01-1.83), and more frequently used oral anticoagulants in therapy before the surgery-OR 2.16 (1.11-4.19). According to the results obtained, overweight and obesity were not associated with an increased death rate, transient ischemic attack (TIA), stroke, myocardial infarction, or with minor complications, and the need for reoperation after carotid endarterectomy. The only exception was bleeding, which was significantly less frequent after CEA in overweight compared to normal weight patients.

Abstract
Carotid endarterectomy (CEA) is a widespread and safe procedure associated with very little risk. Only at our hospital surgeons perform nearly 1000 of these surgeries annually, with serious complications occurring extremely rarely[1]. Cerebral ischemic events due to external carotid artery (ECA) thrombosis following a successful internal carotid artery (ICA) endarterectomy is one of such complications. We present a case of ECA thrombosis, following ICA endarterectomy that caused ischemic events.

Abstract
PURPOSE Carotid artery stenting (CAS) is an option for carotid restenosis (CR) treatment with favorable outcomes. However, CAS has also emerged as an alternative to carotid endarterectomy (CEA) for the management of patients with primary carotid stenosis. This study aimed to report CR rates after CAS was performed in patients with primary lesions versus restenosis after CEA, to identify predictors of CR, and to report both neurological and overall outcomes. MATERIALS AND METHODS From January 2000 to September 2018, a total of 782 patients were divided into 2 groups: The CAS (prim) group consisted of 440 patients in whom CAS was performed for primary lesions, and the CAS (res) group consisted of 342 patients with CAS due to restenosis after CEA. Indications for CAS were symptomatic stenosis/restenosis >70% and asymptomatic stenosis/restenosis >85%. A color duplex scan (CDS) of carotid arteries was performed 6 months after CAS, after 1 year, and annually afterward. Follow-up ranged from 12 to 88 months, with a mean follow-up of 34.6±18.0 months. RESULTS There were no differences in terms of CR rate between the patients in the CAS (prim) and CAS (res) groups (8.7% vs 7.2%, χ2=0.691, p=0.406). The overall CR rate was 7.9%, whereas significant CR (>70%) rate needing re-intervention was 5.6%, but there was no difference between patients in the CAS (prim) and CAS (res) groups (6.4% vs 4.7%, p=0.351). Six independent predictors for CR were smoking, associated previous myocardial infarction and angina pectoris, plaque morphology, spasm after CAS, the use of FilterWire or Spider Fx cerebral protection devices, and time after stenting. A carotid restenosis risk index (CRRI) was created based on these predictors and ranged from -7 (minimal risk) to +10 (maximum risk); patients with a score >-4 were at increased risk for CR. There were no differences in terms of neurological and overall morbidity and mortality between the 2 groups. CONCLUSIONS There was no difference in CR rate after CAS between the patients with primary stenosis and restenosis after CEA. A CRRI score >-4 is a criterion for identifying high-risk patients for post-CAS CR that should be tested in future randomized trials.

Abstract
Introduction: Ischemic postconditioning (IPCT) represents one of the several therapeutic strategies to attenuate ischemic reperfusion injury (IR) after carotid endarterectomy (CEA). We here present the first in-human study of IPCT in carotid surgery. Methods: The study represents an observational case-control study, with the data collected in our Institution carotid database. From December 2015 to December 2020, a total of 300 patients were included in our study; IPCT group consisted of 148 patients in whom ischemic postconditioning was performed while control group consisted of 152 patients in whom IPCT was not performed. Indications for IPCT technique were: severe unilateral internal carotid artery (ICA) stenosis (>90%), severe bilateral ICA stenosis (>80%), severe ICA stenosis (>80%) with contralateral ICA occlusion and ICA subocclusion. IPCT was performed by applying 6 cycles of 30 sec reperfusion (declamping of ICA)/30 sec ischemia (clamping of ICA) after finishing the procedure and initial declamping. Two groups of patients were compared in terms of occurrence of intrahospital and early postoperative stroke, TIA (transient ischemic attack) and neurologic morbidity. Results: Cumulative incidence of intrahospital postoperative stroke or TIA was significantly higher in the control group (5.3% vs 0.7%, P = .036). According to carotid plaque characteristics, patients in the IPCT group had significantly more frequent presence of heterogenous plaque, as well as ulcerated plaque, which was associated with the absence of postoperative stroke and significantly lower cumulative rate of TIA/stroke when compared to the control group (43.9% vs 8% and 47.3% vs 1.5%). During the follow-up period of 1 month after the surgery, there were no cases of stroke, TIA and deaths due to neurological causes in both groups of patients. Conclusion: Our results showed that IPCT significantly reduced the incidence of postoperative cerebral ischemic complications after CEA in high-risk patients for IR injury when compared to the control group.

Abstract
BACKGROUND: The coronavirus disease (COVID-19) is characterized by a high prevalence of deep vein thrombosis (DVT), particularly in its severe form, but the incidence of DVT and risk factors for DVT in non-severe patients are still unknown.
METHODS: The study enrolled 118 patients with non-severe COVID-19 infection which did not required hospital admittance. A duplex ultrasound and laboratory test were performed in all the patients after the first negative polymerase chain reaction SARS-CoV-2 test.
RESULTS: DVT was identified in 50 (42.4%) patients with a median age of 48 years (interquartile range 30–85 years). Symptomatic DVT was present in 40 (80%) patients and was commonly seen in the Class I calf vein thrombosis (38 patients, 76%) (χ2 = 51.71, p < 0.001). The most significant risk factors for DVT were as follows: Increased C-reactive protein (p = 0.000), fibrinogen (p = 0.000), low lymphocyte count (p = 0.002), obesity (p = 0.017), and neutrophil count (p = 0.042). The multivariable logistic regression analysis revealed that a D-dimer cutoff point of 1253.5 μg/L showed a sensitivity of 92% and a specificity of 71%.
CONCLUSION: Patients with increased inflammatory markers and obese patients after a non-severe COVID-19 infection should have an ultrasound examination to ensure early diagnosis of DVT and to prevent the occurrence of any complications.

Abstract
Aneurysms of the splenic artery represent a rare clinical entity, even though they account for 60-70% of all visceral artery aneurysms. Splenic artery aneurysms larger than 5 cm are extremely rare, and they are considered to be giant. Possible causes of splenic artery aneurysm development include: trauma, hormonal and local hemodynamic changes in pregnancy, portal hypertension, arterial degeneration, infection and postsplenectomy occurrence. Surgical treatment of giant splenic artery aneurysms includes procedures that frequently require pancreatectomy and splenectomy. We present a case of a 10.2 cm giant splenic artery aneurysm, firmly adhered to the pancreas, which was treated surgically, with spleen and pancreas preservation. SIMILAR CASES PUBLISHED: Although many cases on treatment of giant splenic artery aneurysm have been published, the majority have described additional visceral resections associated with aneurysmectomy, which is in contrast with our report. Furthermore, aneurysms reaching 10 cm in size were extremely rare.

Abstract
BACKGROUND: Aortic graft infection is one of the most serious complications of vascular reconstruction with the incidence of 1%. The clinical presentation can vary, which delays the diagnosis.
CASE REPORTS: Infections in our patients affected iliac, inguinal region, and retroperitoneum, which are not relatively common sites of graft infection. We present clinical presentation, imaging procedures, and surgical treatment of three patients with unknown cause of late graft infection after 6, 7, and 9 years.
CONCLUSION: In our presentations, the etiological factors of the infection are not known, but they suggest that events in the gastrointestinal tract may be related to them. Aggressive surgery should be taken into consideration as a first choice in the similar cases.

Abstract
INTRODUCTION Infection of synthetic graft in the groin is a rare but devastating complication. When it occurs, several possibilities of treatment are available. Extra-anatomic reconstruction and in-situ implantation of new, infection resistant grafts are associated with high mortality and morbidity. Therefore, more conservative approach is needed in some cases. Negative-pressure wound therapy is one of the options in treating such patients. OBJECTIVE The aim of this study was to assess the outcome for deep groin vascular graft infection treated with negative-pressure wound therapy. METHODS Seventeen patients (19 wounds), treated for Szilagyi grade III groin infections between October 2011 and June 2014, were enrolled into this observational study. RESULTS Majority of the wounds (11/19) were healed by secondary intention, and the rest of the wounds (8/19) were healed by primary intention after initial negative-pressure wound therapy and graft substitution with silver-coated prostheses or autologous artery/vein implantation. No early mortality was observed. Minor bleeding was observed in one patient. Reinfection was noted in three wounds. Only one graft occlusion was noted. Late mortality was observed in three patients. CONCLUSION Negative-pressure wound therapy seems to be safe for groin vascular graft infections and comfortable for both patient and surgeon. However, the rate of persistent infection is high. This technique, in our opinion, can be used as a “bridge” from initial wound debridement to definitive wound management, when good local conditions are achieved for graft substitution, either with new synthetic graft with antimicrobial properties or autologous artery/vein. In selected cases of deep groin infections it can be used as the only therapeutic approach in wound treatment.

Abstract
INTRODUCTION The stump wound complications after above-knee amputation lead to other problems, such as prolonged rehabilitation, delayed prosthetic restoration, the increase in total treatment cost and high mortality rates. OBJECTIVE To evaluate the safety and outcomes of negative-pressure wound therapy (NPWT) using Vacuum-Assisted Closure (VAC®) therapy in patients with stump complication after above-knee amputation (AKA). METHODS From January 2011 to July 2014, AKA was performed in 137 patients at the University Cardiovascular Clinic. Nineteen (12.4%) of these patients (mean age 69.3 ± 9.2 years) were treated with NPWT. The following variables were recorded: wound healing and hospitalization time, rate of NPWT treatment failure, and mortality. RESULTS AKA was performed in 17 (89.5%) patients after the vascular or endovascular procedures had been exhausted, while urgent AKA was performed in two (10.5%) patients due to uncontrolled infection. The time before NPWT application was 3.1 ± 1.9 days and the duration of the NPWT use ranged from 15 to 54 days (mean 27.95 ± 12.1 days). During NPWT treatment, operative debridement was performed in 12 patients. All the patients were kept on culture-directed intravenous antibiotics. The average hospital length of stay was 34.7 days (range 21–77 days). There were four (20.9%) failures during the treatment which required secondary amputation. During the treatment, one (5.3%) patient died due to multi-organ failure after 27 days. CONCLUSIONS The use of NPWT therapy in the treatment of AKA stump complication is a safe and effective procedure associated with low risk and positive outcome in terms of wound healing time and further complications.

Abstract
The aim of this article is to review our experience in surgical treatment of carotid atherosclerosis using eversion carotid endarterectomy (ECEA) in 5,034 patients, with particular attention to temporal changes in patients' characteristics, diagnostic approach, surgical technique, medical therapy, and outcome in the early (group A, 1991–1997) versus late (group B 1998–2004) period of ECEA. From January 1991 to December 2004, 5,034 primary ECEAs were performed for high-grade carotid stenosis. Patients treated for restenosis after previous carotid surgery were excluded from the analysis. Group A consisted of 1,714 patients who underwent surgery between 1991 and 1997, and group B consisted of 3,320 patients who underwent surgery between 1998 and 2004. Follow-up included routine clinical evaluation and noninvasive surveillance, with duplex scanning at 1 month after surgery, after 6 months, and annually afterward. Only 3% of patients in group A and 0.6% in group B were asymptomatic, with 23% and 47% of them having preoperative stroke, respectively. In group A, angiography was used for the final diagnosis in 78% of patients. In group B, duplex scanning was performed in 82% of patients and angiography in only 18% ( p < .001). Clamping time was shorter in the latter group (12.4 ± 3.1 vs 14.5 ± 4.1 min, p < .01). Introperative shunting and regional anesthesia were rarely performed in both groups (1.4% vs. 0.4%, p < .01, and 2% vs 0.3%, p < .001). Total and neurologic morbidity was significantly higher in group A than in group B (6.41% ± 0.47% vs 4.81% ± 0.53%, p < .001, and 2.14% ± 0.31% vs 1.23% ± 0.29%, p < .001, respectively). Total mortality was also higher in group A than in group B (1.92% ± 0.24% vs 1.36% ± 0.50%, p < .05), but although there was a trend toward lower neurologic mortality, it did not reach statistical significance (1.04% ± 0.5% vs 0.57% ± 0.25%, p = .074). There was a lower rate of nonsignificant restenosis (< 50%) in group B (2% vs 5%, p < .01), but the incidence of restenosis ≥ 50% was identical between the groups (5.5% for both). Our data show that ECEA is a reliable surgical technique for the treatment of atherosclerotic carotid disease. Temporal trends in our patients demonstrated a decline in periopertive mortality and morbidity, despite a higher incidence of preoperative stroke.

Abstract
INTRODUCTION In this report, we aim to present a rare case of isolated internal iliac artery aneurysm with associated left ureteric obstruction and consequent hydronephrosis. CASE REPORT A 66-year-old male patient was admitted for occasional pain in the lower back that appeared one month earlier. CT arteriography revealed isolated internal iliac artery (diameter 99 mm) with ureteral obstruction, hydroureter and left kidney hydronephrosis occurrence. Aneurysm was resected, after six months the patient was doing well. Bearing in mind that 77% of the patients with isolated internal iliac artery have symptoms caused by aneurysmal compression on adjacent organs, we wanted to highlight that despite the amazing expansion of endovascular procedures in the last decades, its therapeutic effect in isolated internal iliac artery's treatment is to a great extent limited since compression symptoms cannot be solved. CONCLUSION Open surgery remains the gold standard for isolated internal iliac artery's treatment considering significant limitations of endovascular procedures due to the inability to eliminate problems caused by compression.

Abstract
Purpose The purpose of this study was to analyze clinical outcome of patients for femoropopliteal graft infection who were treated by in situ reconstruction with a silver-coated prosthesis. Basic methods From December 2001 to December 2011, 27 patients were treated for femoropopliteal graft infection. Twenty patients (74%) were male and seven (26%) were female. Mean age was 65 years. The primary endpoint was recurrence of infection. Secondary endpoints were early and late mortality and morbidity, primary graft patency, major amputation rates and patient survival. Principal findings Early reinfection occurred in 11% and late in 8% of patients. Perioperative mortality was 7% and late was 4%. Above-knee amputation was performed in 4% of patients during early postoperative course and in 12% of patients during follow-up. Early and late graft patency was 96% and 72%, respectively. Conclusions Results of in situ implantation of silver-coated grafts for femoropopliteal prosthesis infection are according to our opinion acceptable, but the risk of reinfection remains.

Abstract
To analyze the outcome of urgent carotid endarterectomy (CEA) performed within less than six hours in patients with crescendo transient ischemic attack (TIA) and stroke in progression. From January 1998 to December 2008, 58 urgent CEAs were done for acute neurological ischemic events – 46 patients with crescendo TIA and 12 patients with stroke in progression. Brain computed tomography (CT) was done prior and after the surgery. Disability level was assessed prior to and after urgent CEA using modified Rankin scale. Median follow-up was 42.1 ± 16.6 months. In the early postoperative period stroke rate was 0% for the patients in crescendo TIA group while in patients with stroke in progression group 3 patients (25%) had positive postoperative brain CT, yet neurological status significantly improved. Mid-term stroke rate was 2.2% in crescendo TIA group and 8.3% in stroke in progression group. In the early postoperative period there were no lethal outcomes, mid-term mortality was 8.3% in stroke in progression while in crescendo TIA group lethal outcomes were not observed. In conclusion, based on our results urgent CEA is a safe and effective treatment option for patients with crescendo TIA and stroke in progression with acceptable rate of postoperative complications.

Abstract
INTRODUCTION In this report, we aim to present a very rare case of internal carotid artery (ICA) aneurysm secondary to kinking and cystic medial degeneration. CASE REPORT A 66-year-old female patient was admitted to our institution for multidetector computed tomography (MDCT) angiography of supra-aortic trunks. On admission, she complained of occasional dizziness; 2 months earlier ascending aorta reconstruction was done for aneurysmal disease. Color Doppler ultrasonography and MDCT arteriography revealed significant right ICA kinking associated with large aneurysm, 24.6 × 24.5 mm(2) in diameter. Aneurysm resection was done followed by ICA reconstruction by end-to-end anastomosis. Pathohistological findings of aneurysmal sac revealed cystical medial degeneration with inflammatory infiltrate mostly consisting of lymphocytes and fibrovascular proliferation. CONCLUSION This is the first case that describes mutual contribution of cystic medial degeneration and ICA kinking in carotid aneurysm disease etiology successfully treated by aneurysm resection.

Abstract
BACKGROUND To evaluate safety, short and long-term graft patency, clinical success rates, and factors associated with patency, limb salvage and mortality after surgical reconstruction in patients younger than 50 years of age who had undergone unilateral iliac artery bypass surgery. PATIENTS AND METHODS From January 2000 to January 2010, 65 consecutive reconstructive vascular operations were performed in 22 women and 43 men of age < 50 years with unilateral iliac atherosclerotic lesions and claudication or chronic limb ischemia. All patients were followed at 1, 3, 6, and 12 months after surgery and every 6 months thereafter. RESULTS There was in-hospital vascular graft thrombosis in four (6.1 %) patients. No in-hospital deaths occurred. Median follow-up was 49.6 ± 33 months. Primary patency rates at 1-, 3-, 5-, and 10-year were 92.2 %, 85.6 %, 73.6 %, and 56.5 %, respectively. Seven patients passed away during follow-up of which four patients due to coronary artery disease, two patients due to cerebrovascular disease and one patient due to malignancy. Limb salvage rate after 1-, 3-, 5-, and 10-year follow-up was 100 %, 100 %, 96.3 %, and 91.2 %, respectively. Cox regression analysis including age, sex, risk factors for vascular disease, indication for treatment, preoperative ABI, lesion length, graft diameter and type of pre-procedural lesion (stenosis/occlusion), showed that only age (beta - 0.281, expected beta 0.755, p = 0.007) and presence of diabetes mellitus during index surgery (beta - 1.292, expected beta 0.275, p = 0.026) were found to be significant predictors of diminishing graft patency during the follow-up. Presence of diabetes mellitus during index surgery (beta - 1.246, expected beta 0.291, p = 0.034) was the only variable predicting mortality. CONCLUSIONS Surgical treatment for unilateral iliac lesions in patients with premature atherosclerosis is a safe procedure with a low operative risk and acceptable long-term results. Diabetes mellitus and age at index surgery are predictive for low graft patency. Presence of diabetes is associated with decreased long-term survival.

Missed dissection as a result of the ascending pharyngeal artery arising from the internal carotid artery. Ann Vasc Surg 2011; 25:701.e5-8. [PMID: 21546212 DOI: 10.1016/j.avsg.2011.02.009] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2010] [Revised: 11/30/2010] [Accepted: 02/08/2011] [Indexed: 11/29/2022]
Abstract
Unlike high-grade stenosis, dissections of craniocervical arteries are a rare cause of cerebrovascular infarction. If the internal carotid artery (ICA) dissection is verified by duplex scanning or computed tomography angiography (CTA), the therapies of choice are antiplatelet and anticoagulation drugs, and surgical treatment is rarely performed. However, despite distinct clinical and radiological manifestation, carotid dissections are still under-recognized. In this study, we demonstrate the case of a 66-year-old man with dissection of ICA verified by duplex scanning and computed tomography angiography. The cause of missed diagnosis was an ascending pharyngeal artery originating from the ICA that runs parallel to it. Other than being a rare variation, this case may be interesting as a cause of misdiagnosis.

Abstract
INTRODUCTION Hypersplenism is a common complication of portal hypertension. Cytopenia in hypersplenism is predominantly caused by splenomegaly. Distal splenorenal shunt (Warren) with partial spleen resection is an original surgical technique that regulates cytopenia by reduction of the enlarged spleen. OBJECTIVE The aim of our study was to present the advantages of distal splenorenal shunt (Warren) with partial spleen resection comparing morbidity and mortality in a group of patients treated by distal splenorenal shunt with partial spleen resection with a group of patients treated only by a distal splenorenal shunt. METHOD From 1995 to 2003, 41 patients with portal hypertension were surgically treated due to hypersplenism and oesophageal varices. The first group consisted of 20 patients (11 male, mean age 42.3 years) who were treated by distal splenorenal shunt with partial spleen resection. The second group consisted of 21 patients (13 male, mean age 49.4 years) that were treated by distal splenorenal shunt only. All patients underwent endoscopy and assessment of oesophageal varices. The size of the spleen was evaluated by ultrasound, CT or by scintigraphy. Angiography was performed in all patients. The platelet and white blood cell count and haemoglobin level were registered. Postoperatively, we noted blood transfusion, complications and total hospital stay. Follow-up period was 12 months, with first checkup after one month. RESULTS In the first group, only one patient had splenomegaly postoperatively (5%), while in the second group there were 13 patients with splenomegaly (68%). Before surgery, the mean platelet count in the first group was 51.6 +/- 18.3 x 10(9)/l, to 118.6 +/- 25.4 x 10(9)/l postoperatively. The mean platelet count in the second group was 67.6 +/- 22.8 x 10(9)/l, to 87.8 +/- 32.1 x 10(9)/l postoperatively. Concerning postoperative splenomegaly, statistically significant difference was noted between the first and the second group (p < 0.05). Comparing the postoperative platelet count between the first and second group, we found that there was a very significant statistical difference, too (p < 0.01). CONCLUSION Distal splenorenal shunt (Warren) with partial spleen resection is a very reliable surgical technique in treatment of hypersplenism and decompression of oesophageal varices caused by portal hypertension and has advantage in treatment of hypersplenism over the distal splenorenal shunt method.

Abstract
It has been thought that the spleen is an organ without important functions, until recently. That is, why splenectomy has been the procedure of choice in a treatment of splenic diseases. Even now, when we know the functional [figure: see text] importance of the spleen, splenectomy is performed frequently, regardless of its complications. The need of spleen functions salvage, favours partial resection of the spleen as competitive in a treatment of its traumatic and benign lesions. Improvement in diagnostic procedures, surgical techniques, transfusiology and postoperative treatment, will promote it as a treatment of choice. The authors of this study have experience with 17 partial resections of the spleen for traumatic, 11 for benign lesions of the spleen, and one ectopic spleen with hypersplenism, without mortality and with insignificant complications.

Abstract
Some of serious hepatic diseases with cirrhosis may be complicated by portal hypertension, splenomegaly and hypersplenism. Splenomegaly inhibits regenerative processes of the liver, and also intensifies sequestration of the cellular components of blood up to hypersplenism. Cytopenia caused by hypersplenism is aggravated by negative hepatic influence on bone marrow activity-hemathopoesis, and also by recurrent bleeding from oesophageal varices, and from the other site of gastrointestinal tract. This circle of pathologic conditions may be interrupted only by liver transplantation, until which patients are jeopardized by acute bleeding and chronic anemia. Partial resection of the spleen and splenorenal shunt may correct portal hypertension and hypersplenism, prevent gastrointestinal bleeding, and alleviate hepatic regenerative processes inhibition. In this study, 51 patients with partial resection of the spleen and splenorenal shunt, were analyzed.
