Superior mesenteric vein thrombosis after colectomy in a patient with Crohn's disease

Splanchnic Vein Thrombosis in Inflammatory Bowel Disease: An Observational Study from the ENEIDA Registry and Systematic Review

BACKGROUND

Thromboembolic events are frequent among patients with inflammatory bowel disease (IBD). However, there is little information on the prevalence, features and outcomes of splanchnic vein thrombosis (SVT) in patients with IBD.

AIMS

To describe the clinical features and outcomes of SVT in patients with IBD and to perform a systematic review of these data with published cases and series.

METHODS

A retrospective observational study from the Spanish nationwide ENEIDA registry was performed. A systematic search of the literature was performed to identify studies with at least one case of SVT in IBD patients.

RESULTS

A new cohort of 49 episodes of SVT from the Eneida registry and 318 IBD patients with IBD identified from the literature review (sixty studies: two multicentre, six single-centre and fifty-two case reports or case series) were analysed. There was a mild predominance of Crohn's disease and the most frequent clinical presentation was abdominal pain with or without fever followed by the incidental finding in cross-sectional imaging techniques. The most frequent SVT location was the main portal trunk in two-thirds of the cases, followed by the superior mesenteric vein. Anticoagulation therapy was prescribed in almost 90% of the cases, with a high rate of radiologic resolution of SVT. Thrombophilic conditions other than IBD itself were found in at least one-fifth of patients.

CONCLUSIONS

SVT seems to be a rare (or underdiagnosed) complication in IBD patients. SVT is mostly associated with disease activity and evolves suitably when anticoagulation therapy is started.

Cerebral venous thrombosis in inflammatory bowel disease

Cerebral venous thrombosis (CVT) is a rare but devastating complication of inflammatory bowel disease (IBD). Here we describe six IBD patients with cerebral venous thrombosis. The patients presented with hours to days of headache and were found to have venous thrombosis on imaging. Four of the six patients had ulcerative colitis and two had Crohn's disease. All six patients were treated with therapeutic anticoagulation. There were two deaths; one patient became comatose and died despite anticoagulation while the other recovered well from the sinus thrombosis but died after a bowel perforation 3 weeks later. This case series demonstrates the critical need for early recognition of neurological symptoms in patients with IBD during disease flares. It is important to recognize the clinical signs in order to start anticoagulation expeditiously and improve neurological outcomes.

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

•

Whipple procedure (pancreatoduodenectomy) is an extensive procedure carrying risk of a number of postoperative complications.

•

Thrombosis of superior mesenteric vein is a complication that requires aggressive therapeutical approach.

•

Mesenteroovarian anastomosis is one of the options if thrombectomy is not feasible.

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.

Superior mesenteric vein occlusion causing severe gastrointestinal haemorrhage in two paediatric cases

Reports about superior mesenteric vein thrombosis in childhood are very rare and have not been associated with gastrointestinal bleeding. We describe two cases of severe bleeding from the upper and lower gastrointestinal tract in children who had undergone complex abdominal surgery at considerable time before. The first child had a tracheoesophageal fistula, corrected by division, gastrostomy insertion, and repair of duodenal rupture. The child presented with severe bleeding from the gastrostomy site and was diagnosed with a thrombosis of the proximal superior mesenteric vein. The second child had a gastroschisis and duodenal atresia, and required duodenoplasty, gastrostomy insertion, hemicolectomy, and adhesiolysis. The child presented with intermittent severe lower gastrointestinal bleeding, resulting from collateral vessels at location of the surgical connections. He was diagnosed with a thrombosis of the superior mesenteric vein. In both children, the extensive previous surgery and anastomosis were considered the cause of the mesenteric thrombosis. CT angiography confirmed the diagnosis in both cases, in addition to characteristic findings on endoscopy. Paediatricians should suspect this condition in children with severe gastrointestinal bleeding, particularly in children with previous, complex abdominal surgery.

Thromboembolism in pediatric inflammatory bowel disease: systematic review

BACKGROUND

Several studies suggest an increased risk of venous and arterial thromboembolism (TE) in adults with inflammatory bowel disease (IBD) compared to the general population. We performed a systematic review of studies on incidence and characteristic of TE in children with IBD.

METHODS

We searched Medline, LILACS, EMBASE, POPLINE, CINHAL, and reference lists of identified articles, without language restrictions, in August 2010.

RESULTS

Population studies suggest that there is an increased risk of TE in children with IBD compared to controls. TE occurred in children with IBD in all age ranges, mostly (82.8%) during active disease, and more frequently in children with ulcerative colitis (odds ratio [OR] 3.7, 95% confidence interval [CI] 1.8-7.6). At least one specific risk factor for TE was recognized in 50% of cases; two risk factors were present in 24%. Out of 92 published cases of TE in children with IBD, 54.3% occurred in cerebral site, 26% in the limbs, 13% in the abdominal vessels, and the remaining in the retina and lungs. After a first episode of TE, an early recurrence was observed in 11.4% of children, a late recurrence in 10%. A number of different therapeutic schemes were used. Overall mortality was 5.7% and was mostly associated with cerebral TE.

CONCLUSIONS

Population studies are needed to clarify the risk of TE in children with IBD, the relative weight of other risk factors, the characteristics of the events, and to define guidelines of therapy and prophylaxis.

Intra-abdominal venous and arterial thromboembolism in inflammatory bowel disease

Venous and arterial thromboembolism constitutes a significant cause of morbidity and mortality in patients with inflammatory bowel disease. The most common thrombotic manifestations are lower extremity deep vein thromboses with or without pulmonary embolism. Occasionally, thromboembolic events occur in the main abdominal vessels, such as the portal and superior mesenteric veins, vena cava and hepatic vein, aorta, splanchnic and iliac arteries, or in the limb arteries. The decision-making process for the treatment of these uncommon thromboembolic complications in inflammatory bowel disease may be very challenging for several reasons: 1) no standardized therapies are available; 2) the decision of starting anticoagulant therapy implies the potential risk of intestinal bleeding; 3) thromboembolic events may recur and be life-threatening if inadequately treated. The literature was searched by using MEDLINE, Embase, and the Cochrane library database. Studies published between 1970 and 2007 were reviewed. We discuss the medical and surgical therapeutic options that should be considered to optimize the outcome and reduce the risk of complications in abdominal thromboembolisms associated with inflammatory bowel disease.
