Hybrid procedure in a patient with symptomatic thoraco-abdominal aneurysm and prior abdominal aortic reconstruction - case report.

Open repair of thoracoabdominal aortic aneurysm is connected with high mortality and morbidity. On the other hand, endovascular treatment of thoraco-abdominal aneurysms, which started 10 years ago, reduced perioperative mortality and morbidity. However, it results in a high level of late complications. It seems that an interesting solution to the problem is a hybrid procedure, which allows late complications to be reduced with acceptable levels of operative mortality and morbidity. This case report presents the use of a hybrid procedure in treatment of symptomatic thoraco-abdominal aneurysm in a patient with prior abdominal aortic reconstruction. In the first stage the patient underwent open revascularization of visceral vessels of the aorta. One week later a thoraco-abdominal stent-graft was implanted. The perioperative and postoperative period was uncomplicated. Two months after the second intervention the patient returned to work. Control imaging conducted 30 and 90 days after the procedure confirmed patency of all revascularized vessels and did not reveal any graft-related complications. The hybrid procedure seems to be an interesting alternative for open and endovascular repair of thoraco-abdominal aneurysms because it combines the advantages of open and endovascular repair. It also gives an opportunity to perform the procedure within a reasonable period of time from diagnosis of symptomatic thoraco-abdominal aneurysm.

All dangerous types of endoleaks after endovascular aneurysm repair in a single patient.

Endovascular aneurysm repair (EVAR) has become tremendously popular in recent years. However, the long-term results of these stent grafts are uncertain and are still being evaluated. According to some data, the graft-related complication rate after EVAR could be as high as 43% in long-term observation. In this case report, we present a patient who had all dangerous types of endoleaks after EVAR and required sophisticated management including endovascular and open surgical repairs. After repeated invasive treatment, it was possible to exclude all endoleaks, and now the patient is free from graft-related complications. Although EVAR has become very popular, we should remember about possible complications, which could be very severe and life-threatening. For this reason, the choice between endovascular and open repair of abdominal aortic aneurysm should be well considered.

Can deep vein thrombosis be predicted after varicose vein operation in women in rural areas

INTRODUCTION Chronic venous disease is a group of symptoms caused by functional and structural defects of the venous vessels. One of the most common aspects of this disease is the occurrence of varicose veins. There are many ways of prevention and treatment of varicose veins, but in Poland the leading one is still surgery. As in every medical procedure there is the possibility of some complications. One of them is deep vein thrombosis (DVT). The diagnosis of DVT can be difficult, especially when access to a specialist is limited, such as in case of rural patients. The aim of the study. The aim of the study was estimation of the influence of LMWH primary prophylaxis on the formation of postoperative DVT, as well as sensitivity and specificity of clinical examination and D-dimer value in diagnosis of postoperative DVT in women. MATERIALS AND METHODS The study was conducted in a group of 93 women operated on in the Department of General, Vascular Surgery and Angiology at the Karol Marcinkowski University of Medical Sciences in Poznań, Poland. The patients had undergone a varicose vein operation and were randomly divided into two groups: A - 48 women receiving LMWH during two days of the perioperative period, B - 45 women receiving LMWH during seven days of the perioperative period. RESULTS There was no significant difference in the postoperative DVT complications in both groups. The value of D-dimer > 0.987 mcg/ml and swelling > 1.5 cm of shin (in comparison to the preoperative period) plays a significant role in diagnosis of DVT. CONCLUSIONS The extended primary prophylaxis with LMWH does not affect the amount or quality of thrombotic complications after varicose vein operation. If the DVT occurs, the evaluation of the D - dimer and careful clinical examination can be a useful method for its diagnosis.

A rare case of a right common iliac venous aneurysm imitating a neoplastic tumour

BackgroundAneurysms of the deep lower limbs veins are extremely rare. Diagnosis of such conditions may be confusing and suggest the presence of a neoplastic lesion.Case presentationWe herein report a case of a 68-year-old woman who was admitted with a large vein tumour revealed by sonography and computed tomography. A direct phlebography revealed a large venous aneurysm of the right common iliac vein with an adhering thrombus and a large collateral circulation. Anticoagulant treatment and compression with an elastic stocking were initiated because the patient refused surgical treatment. A 2-year follow-up showed no aneurysm growth or thromboembolic complications.ConclusionsWe show herein that conservative management can be effective and safe in cases of this rare condition.

Lack of Serum Creatinine Decrease After Coronary Angiography Despite Prophylactic Hydration After Routine Coronary Angiography/Angioplasty in Stable Angina Patients--Pilot Study.

Background/Aims: To prevent contrast induced renal dysfunction a periprocedural prophylactic hydration is applied. Due to dilution it should cause a drop in serum creatinine concentration (SCR). Surprisingly, no reduction in SCR after contrast admission is found in up to 25% of patients as early as 12-18 hours after coronary angiography/angioplasty. This study aims to find a clinical explanation as well as predict circumstances for this phenomenon. Methods: Retrospective clinical and laboratory data was used from 341 patients who underwent elective coronary angiography/angioplasty, received a prophylactic hydration, and had serum creatinine concentration measured prior to, and 12-18 hours after invasive procedure with iodine contrast administration. To exclude an improper hydration due to no creatinine decrease, the number of red blood cells was analysed as well as hemoglobin and hematocrit in blood donations collected during the study time points. Results: The resulting lack of serum creatinine reduction could be explained by dehydration (measured by increase in number of RBC, HGB and HCT) only in 13.5% , 10.8 %, and 20% of cases, respectively. Any form of abnormal glucose metabolism combined with either baseline serum creatinine concentration <0.87 mg/dL or creatinine clearance >86.77 mL/min, or GFR by CKD EPI >80.08 mL/min/1.73 m2, or GFR by MDRD >74.48 mL/min/1.73 m2 were the predictors for no creatinine decrease at outcome. Additionally, it was demonstrated that the lack of creatinine decrease was more often observed among those patients whose initial renal function was better than in the subjects with reduction of SCR. Conclusions: This observation requires further prospective investigation on extended group of patients.

Unusual abdominal aneurysms in a patient after kidney transplantation treated by endovascular technique

While abdominal aortic aneurysms are quite common, visceral aneurysms are a seldomly diagnosed vascular pathology. Aneurysms of renal arteries, abdominal aorta and iliac arteries seem to be very rare. We present a patient after renal transplantation with aneurysms of both stumps of the renal arteries, abdominal aortic aneurysm and aneurysms of common iliac arteries. Because of the symptomatic course, the patient required urgent treatment. A successful endovascular procedure was performed. Follow-up imaging did not reveal any complications.

Summary Introduction Free flaps with vascular anastomosis have been widely used in clinical practice for more than 30 years. They are standard in reconstructive surgery following extensive resections caused by neoplasms of the head and neck. The anterolateral thigh flap (ALT) constitutes very good reconstructive material due to the long vascular pedicle, the appropriate diameter of vessels, the large skin island plane, and thickness depending on requirements. Material The own material comprises 5 patients who have had extensive neoplastic infiltrations removed at different anatomic locations within the area of healthy tissue. Results Reconstructions have been conducted using a microvascular thigh flap (ALT). All of the operated patients are under constant supervision. The observation period ranges from 2 to 3 months. No recurrence of the neoplastic process or graft rejection has been observed in any of the patients.
