ABSTRACT
Aim To compare long-term outcomes of x-ray endovascular (percutaneous coronary intervention, PCI, and lower limb angioplasty with stent placement, LLA; group 1) and combination treatments (PCI and open LLA surgery; group 2) in patients with chronic lower limb ischemia (CLLI) associated with ischemic heart disease (IHD).Material and methods This retrospective study has been conducted in the Vishnevsky National Medical Research Center of Surgery since 2019. The study includes 92 patients with stage 2B CLLI associated with IHD who were managed from January 1, 2017 through December 31, 2020. Long-term outcomes were evaluated in 76 (82.6â%) patients. The endpoint was severe cardiovascular complications (CVC), including death, myocardial infarction, and acute cerebrovascular disease (ACVD).Results In group 1 during the long-term period, 1 (2.7%) fatal outcome due to pneumonia was observed. In group 2, 4 (10â%) patients died: 1 (2.5â%) patient due to ACVD, 1 (2.5â%) patient due to progression of oncological process, and 2 2 (5â%) patients due to COVID-19. Also, 2 (5.5â%) and 1 (2.5â%) cases of acute coronary syndrome (ACS) were observed in groups 1 and 2, respectively (p=0.61).Conclusion In the x-ray endovascular (group1) and the combination (group 2) intervention groups, lethal outcomes due to myocardial infarction were absent. This fact confirms the importance of PCI in patients with CLLI for prevention of possible ACS in the long-term. Both therapeutic tactics in managing CLLI patients with IHD demonstrated high safety and clinical efficacy during the hospital and long-term periods and can be extensively used in routine clinical practice.

OBJECTIVE: To evaluate technical aspects and clinical results of transcatheter arterial embolization (TAE) for delayed postoperative arterial bleeding after pancreatic surgery. MATERIAL AND METHODS: There were 821 pancreatectomies between 2012 and 2020. Delayed bleeding occurred in 106 (12.9%) patients; 74 patients were included in the study. Previous pancreatic head resection was carried out in 75.7% of cases, pancreatic body resection - in 17.6% of cases, pancreatic tail resection - in 6.8% of patients. Primary endpoint was technical success of TAE, secondary endpoints - complications after TAE, as well as recurrent bleeding after embolization. RESULTS: Angiography of celiac-mesenteric arterial system was performed in 74 patients (91 procedures). The most common sources of bleeding were gastroduodenal and superior mesenteric arteries (35.7%), jejunal arteries (13.1%), common hepatic artery (11.9%). Combination of embolization agents was applied for TAE (metal coils and non-calibrated PVA particles, 48.6%). In 11 (14.9%) patients, we applied stent-grafts. Technical success rate was 100%. Recurrent bleeding occurred in 13 (17.6%) patients. In-hospital mortality was 12.2% (n=9). CONCLUSION: TAE is an effective treatment procedure in patients with arrosive bleeding. This method is characterized by high technical efficiency and low in-hospital mortality, but it does not affect recurrence of bleeding.

Aim To compare in-hospital outcomes (severe cardiovascular complications, CVC) in patients with IIB stage chronic lower limb ischemia (CLLI) in combination with ischemic heart disease (IHD) in the following groups: stepwise percutaneous coronary intervention (PCI) and stenting and angioplasty of lower limb arteries (LLA) (group 1) and combination treatment, including PCI and open surgery on LLA (group 2).Material and methods Since 2019, the A.V. Vishnevsky National Medical Research Center of Surgery has performed a retrospective study that includes patients with stage IIB CLLI in combination with IHD. Patients were divided into 2 groups: group 1 (n=46), stepwise X-ray endovascular treatment (PCI and stenting and angioplasty of LLA); group 2 (n=46), stepwise combination treatment (PCI and open surgery on LLA). The endpoint included severe CVCs (death, acute myocardial infarction, acute cerebrovascular disease) and severe complications in the LLA area (stent thrombosis, repeated intervention on LLA, amputation).Results In 198 surgeries, none of 92 patients had severe CVC, and no fatal outcomes were observed. In group 2, there was one (2.1â%) severe complication on LLA during the early postoperative period, for which a successful additional intervention was performed.Conclusion Individualized approach to care of each patient with LLA pathology in combination with IHD helps avoiding severe CVCs at the hospital stage. It was shown that X-ray endovascular and combination treatments are safe and effective in the absence of fatal outcomes and acute disorders of coronary circulation at the hospital stage.

OBJECTIVE: To report own experience in the treatment of patients with proinsulinoma. MATERIAL AND METHODS: There were 10 patients with increased proinsulin production and normal insulin level since 2017. Most of them were young women. RESULTS: Fasting hypoglycemia in all patients was severe (up to 0.7 mmol/l). Clinical picture consisted of typical symptoms similar to those in insulinoma. The main difference in the course of proinsulinoma was the absence of weight gain in 7 patients and rapid weight loss (from 210 to 90 kg within 9 months) in 1 patient. All patients with proinsulinoma underwent surgery. In most cases, minimally aggressive surgery was performed. CONCLUSION: Proinsulinoma is an extremely rare endocrine-active neuroendocrine pancreatic tumor. Differential features of proinsulinoma are the absence of weight gain and normal insulin levels in the presence of hypoglycemia. Surgery is the only radical method of treatment.

A composition in the form of liquid polymer substance intended for embolization procedures was studied in in vivo experiment. The preparation was injected to rabbits into the femoral artery and abdominal aorta. The polymer composition exhibited properties previously demonstrated in vitro: strong adhesion to the vascular wall, high plasticity sufficient for embolization of the blood vessels, distal distribution, and the absence of toxic effects. The contrast substance remained in the embolus, which simplified its further localization. The agent underwent nether resorption nor organization. Injection of the agent in a volume of 0.1 ml was sufficient for embolization of an artery with a diameter of 0.1 cm. The polymer composition completely obstructed the vessel without inducing perforation of its wall. During the first day of the experiment, a slight infiltration of surrounding tissues with lymphoid cells was observed. By day 7, total dry necrosis of pelvic limb distal to the injection site was diagnosed. Inflammation of the surrounding tissues was shown histologically and was considered as the body response to impaired circulation and necrosis.

AIM: To evaluate an effectiveness of endovascular techniques in pancreatic surgery. MATERIAL AND METHODS: For the period 1995-2017 at Vishnevsky Institute of Surgery endovascular treatment (EVT) was applied in 51 patients with chronic pancreatitis complicated by false aneurysms (FA) and postoperative hemorrhage after pancreatectomy. Various methods of embolization and stenting were used in 24 and 11 cases respectively in order to exclude FA of celiac trunk and superior mesenteric artery from blood flow. Endovascular hemostasis for postoperative hemorrhage was carried out with embolization of damaged vessel in 11 patients. Stent-grafts were deployed in 5 patients with marginal defect of the wall of hepatic/superior mesenteric arteries. RESULTS: In all 35 patients with chronic pancreatitis complicated by false aneurysms EVT ensured thrombosis of the aneurysm's cavity. EVT was final in 14 patients with FA and absent communication with pancreatic duct. Radical surgical treatment was required after 7-10 days for FA communicated with pancreatic duct due to lysis of thrombotic masses by pancreatic enzymes. Spleen infarction was diagnosed in 3 patients. Two of them did not require treatment while 1 patient underwent splenectomy in view of splenic abscess. 1 patient died from liver cirrhosis followed by severe hepatic failure, death was not associated with bleeding. In 16 patients with post-pancreatectomy bleeding hemostasis was achieved in all cases with EVT. However, recurrent bleeding occurred in 2 patients who underwent successful redo endovascular intervention. Complications after EVT were observed in 2 patients: duodenal wall necrosis followed by fistula which was closed spontaneously (n=1); advanced intestinal infarction (n=1) followed by fatal outcome; pulsating hematoma within cubital fossa that required brachial artery ligation and autovenous bypass. CONCLUSION: EVT provides thrombosis of FAs of celiac trunk and superior mesenteric artery branches in patients with chronic pancreatitis, as well as hemostasis for postoperative bleeding after pancreatectomy.

The authors describe herein the use of balloon-distensible stent grafts for endovascular treatment of patients presenting with traumatic arteriovenous fistulas in the first segment of the vertebral artery, exemplified by two clinical case reports. In both cases, the arteriovenous fistula formed after a stab-and-slash wound in the neck area. In order to exclude the arteriovenous aneurysm from the blood flow in the first case we performed endoprosthetic repair of the first segment of the subclavian artery with shutting off of the ostium of the vertebral artery carrying the aneurysm. In the second case, in order to remove the arteriovenous shunt we carried out performed endoprosthetic repair of the first segment of the vertebral artery. These cases show possibilities of roentgenoendovascular methods of treatment, making it possible to successfully replace technically complicated surgical interventions in traumatic arteriovenous fistulas of vertebral arteries.

Arteriovenous dysplasia is rather uncommon disease, quite often leading to severe complications even in young age. Involvement of the osseous apparatus into the pathological process is frequently associated with the problem of amputation of the affected limb. Therefore, salvage of the extremity while removing arteriovenous shunt and trophic impairments is an extremely important clinical task. In the presented herein clinical case report, a female patient with arteriovenous angiodysplasia of the lower limb with the tibial bone involved into the pathological process underwent repeated stagewise embolisations, failing however to achieve complete liquidation of the arteriovenous reflux. In this connection, after removal of angiomatous tissues, requiring also excochleation of the damaged portions of the bone, in order to reinforce the axis of the tibial bone the intramedullary canal of the latter was filled with polymethylmethacrylate (PMMA). Expansion of the spectrum of auxiliary methods, besides the most frequently performed in such patients embolisations of afferent arteries and removal of angiomatous tissues would make it possible to increase radical nature of interventions with salvage of the supporting function of limbs.

AIM: To summarize the experience of endovascular treatment of traumatic arteriovenous fistulae. MATERIAL AND METHODS: Endovascular interventions for arteriovenous fistulae of different locations were applied in 16 patients aged 19 to 83 years (mean 50.4±14.3) in A.V. Vishnevskiy Institute of Surgery from 2003 to 2014. Among causes there were stab wounds, gunshot wounds, blunt trauma, iatrogenic. Different endovascular methods including stenting with self-opening and balloon-expanding stent-grafts, embolic coils and occluders implantation were used. RESULTS: Pain syndrome, disorders of support function and trophic changes were observed in patients with arteriovenous fistulae more localized more distal than lower one third of the thigh. More proximally located arteriovenous fistulae regardless of their diameter resulted severe heart failure and portal hypertension. Angiographic and clinical success was achieved in 100% of cases. Manifestations of heart failure and portal hypertension disappeared in all patients after endovascular interventions. Also support function restored, pain and trophic disorders were cured. CONCLUSION: Arteriovenous fistulae regardless of their size, location and time of existence must be dissociated. Prolonged arteriovenous shunting leads to severe heart failure. Current technologies and tools used in endovascular interventions provide reliable dissociation of arteriovenous fistulae even in case of difficult anatomical features.

The authors describe the use of different methods of endovascular treatment of patients with presenting with posttraumatic arteriovenous fistulas in the first segment of the subclavian artery exemplified by two clinical cases. The first case report concerns a patient having developed was an arteriovenous fistula after catheterization of the jugular vein. The arteriovenous aneurysm was occluded by means of embolizing spirals. In the second case report is patient having developed an arteriovenous fistula after a stab-and-slash wound in the area of the sternoclavicular junction. Long-term existence of the arteriovenous fistula was complicated by severe right-ventricular insufficiency. The arteriovenous fistula was separated by means of endoprosthetic repair of the first segment of the subclavian artery. These case reports demonstrate possibilities of roentgenovascular methods of treatment making it possible to successfully replace a technically complicated, traumatic surgical intervention for false arteriovenous aneurysms.

The authors share herein their experience with an antegrade brachial access for treatment of patients presenting with arteriovenous angiodysplasia localizing on the distal portions of the upper limbs, also describing the choice of the site for puncture and the technique of antegrade catheterization of the brachial artery. This is followed by reporting the results of successful use of this access in a total of 27 patients. The access is simple to create, making it possible to easily perform the intervention using instruments of standard length. It is also safe, requires no bed rest in the postoperative period, and is well tolerated by the patients.

OBJECTIVE: To assess efficacy of the transradial approach and to evaluate possibility of its wide application for coronary interventions as an alternative to the transfemoral access. MATERIAL AND METHODS: A total of 317 percutaneous coronary interventions were performed in 312 patients presenting with coronary artery disease. Percutaneous coronary interventions (PCI) performed through the radial artery (RA) were made using the instruments manufactured by the Terumo Corporation. RESULTS: The right-sided radial approach (RA) was used to perform 172 (54.25%) diagnostic and 42 (13.25%) therapeutic coronary interventions. In 18.30% (n=58) of cases we failed to perform PCI through the RA due to various reasons. Compression haemostasis on the right radial artery in 100% of cases was performed using the device for compression of the puncture site TR Band (Terumo, Japan). Complications related to the approach occurred in 1.25% of cases: thrombosis of the radial artery with no evidence of ischaemia of the hand (n=1), haematoma of soft tissues of the forearm (n=1), haematoma of soft tissues of the shoulder (n=2). A dramatic decrease in the duration of PCI was achieved at the expense of using the RA, hydrophilic guide wire and introducer, universal catheter Tiger and Ikari guide catheters (Terumo, Japan). CONCLUSION: The radial approach makes it possible to perform coronary interventions rapidly, conveniently for both the patient and the roentgenosurgeon. The use of specialized tools makes it possible to perform an atraumatic and mild arterial access, decreasing the rate of haemorrhagic complications, providing rapidity, safety, and full control over PCI.
